Roasting chestnuts at home is easy to do! Learn how to roast chestnuts in your oven or over hot coals! Get tips on how to buy, prepare and store chestnuts, too.
This ultimate guide to roasting chestnuts has been a work in process for the past three years. I've prepped, cooked and shelled more chestnuts than I care to admit, and I've got the burnt fingers to prove it!
I've done by best to include everything you need to know to successfully roast chestnuts at home. I hope you'll find this guide helpful!
If you've never cooked or eaten a chestnut before, you're in for a treat. Freshly roasted chestnuts are delicious!
They do take some work to prepare and cook, and you're going to find more than a few hard or mouldy chestnuts along the way, but it's worth it.
What Are Chestnuts?
Chestnuts are the edible seeds of the sweet chestnut tree that grow inside of a prickly casing called a burr. They have an inedible dark brown outer shell, and a bitter paper-like skin that needs to be removed before eating.
The flesh of a chestnut has a somewhat soft texture, and a sweet nutty flavour. I usually eat mine with melted butter and salt, so it kind of tastes like popcorn, just less crunchy.
Aside from eating them as is, you can also use chestnuts in savoury recipes like Thanksgiving stuffing, or in sweet preparations like Marrons Glacé.
The important thing to remember here is that raw chestnuts must be cooked before you eat them.
Did you know that roasted chestnuts are sold in brown paper bags as a street food in Italy?
Yum!
It's important to note that while chestnuts look similar to conkers - the seed of the horse chestnut tree, they are not the same. Although horse chestnuts are safe for animals to eat, they can be poisonous to humans.
Where to Buy Chestnuts
Fresh raw chestnuts are generally available in groceries and farmers markets around Thanksgiving in Canada and the United States. I usually see them in stores from October to December.
Most of the chestnuts that I've purchased from the grocery have been from either China or Italy. They don't taste exactly the same, but I haven't found that I prefer one over the other.
Imported chestnuts are a good option, but keep in mind that by the time they reach Canadian shelves, they are far from fresh.
This often means that the chestnuts have become dry or mouldy long before you bring them home, and you might not realize it until you've gone through the trouble of cooking and peeling them.
Unfortunately, it can be difficult to tell if a chestnut has gone bad while it's still raw and in the shell. I'll share some tips for selecting good chestnuts below!
Buy Locally Grown if You Can
If you have the option to buy locally grown chestnuts, go for it! The absolute best chestnuts that I've eaten have all been small, locally grown chestnuts.
The level of freshness seems to make a big difference. I get far less bad chestnuts in a pound of locally grown chestnuts compared to imported chestnuts.
Also, small chestnuts cook quickly, and are a breeze to peel compared to large ones.
Check with your local farmers or farmers markets to see if anyone grows chestnuts. I had never thought to check, and then one year I came across tiny chestnuts at a farmer's market in Toronto that were grown in the Niagara region. They were so small that I wasn't sure they'd taste like anything, and they were a bit pricy, but ultimately it was a good purchase.
I've also bought fresh local chestnuts from my friend Lis at Jewels Under the Kilt (seriously, that's her company's name!). Her chestnuts are also quite small, but have a wonderful sweet nutty flavour. Lis usually sells her chestnuts at the Evergreen Brickworks Market in Toronto when they are in season, if she's had a good crop.
How to Select and Store Chestnuts
If your grocery sells chestnuts loose, you can pick through them to find the best ones.
It's important to look at the shells of the chestnuts that you're buying. They should be shiny and hard, with a vibrant brown colour. Look for chestnuts that are heavy for their size, and don't rattle when you shake them.
As chestnuts get older, they become dull, sad-looking and bland. You can see the difference in this photo below.
If the chestnuts are sold pre-packed (where you can't select the individual ones you want), you may end up with chestnuts that are cracked (like the one below), or blemished. These should be discarded.
Lastly, avoid buying chestnuts that are in closed plastic bags. Chestnuts can go mouldy when they aren't able to breathe, so it's a good idea to look for ones sold in mesh or paper bags, or at least plastic bags that have ventilation holes in them.
Be sure to cook your chestnuts soon after purchasing, as they spoil quickly. If you can't cook them right away, refrigerate raw chestnuts in perforated plastic bags for a few days, or freeze in an airtight container for up to one month.
Cooked chestnuts are best eaten immediately, however you can store them in an airtight container in the fridge for the next day if needed. Just reheat them in a pot placed over medium-low heat, and add some butter to the pan to prevent them from becoming too dry.
You can also freeze cooked and peeled chestnuts in a ziptop freezer bag if you can't eat all of them right away.
CAUTION: I have set chestnuts on fire while trying to reheat them in the microwave! Chestnuts loose their moisture during the roasting process, making them a hazard in the microwave. The stovetop method is definitely safer.
How to Prepare Chestnuts for Roasting:
First of all, you should wash your chestnuts.
Yes, I know we're going to be roasting the chestnuts and then peeling them. It doesn't matter that you're not eating the shell - you're going to touch the shell to peel them when you eat them! So be sure to wash them properly before cooking.
Some people recommend soaking chestnuts before roasting them, which allows the meat inside to steam. I haven't found that soaking makes a big difference, but feel free to try it out.
Once your chestnuts are clean, dry them off and place them on a cutting board. You need to cut a slit into the shell of each chestnut, as this allows steam to escape during the cooking process.
Just like a baked potato, if you don't create a hole for the steam to escape, they will explode. And to be honest, some of them might still explode, but it's better to deal with cleaning up just one or two rather than a whole batch of exploded chestnuts.
A sharp sturdy pairing knife or serrated knife are the best tools to get this job done, just be careful not to cut yourself.
You're meant to cut the x into the FLAT side of the chestnut. But if your chestnut is rolling around and you can't get it to sit still round-side down, just cut the round side. At least the steam will have somewhere to escape, and you can avoid cutting yourself.
Traditionally, an "x" is cut into the chestnut, but some people prefer to cut a slit across the point end of the chestnut, like in this video. No matter how you score them, be careful to not cut all the way through. You only want to cut the shell.
Creating a large enough cut makes the chestnuts easier to peel. The cut edges tend to curl back during cooking, giving you something to hold on to when you try to peel them.
When you're scoring the shells, you may find that some are mouldy, or have a bad smell, or are dry and hard. Any chestnuts like these should be thrown away.
How to Roast Chestnuts
We've all heard about chestnuts roasting on an open fire. And while that's a romantic way to prepare these little treats, not everyone has access to a campfire or wood burning fireplace.
Luckily, it's pretty to cook chestnuts in other ways. Most of the time I roast my chestnuts in the oven, but there are other options too.
Just remember that you must cut a slit into each chestnut before roasting chestnuts, or they absolutely will explode.
Also, roasted chestnuts are MUCH easier to peel when they are still very warm. That bitter paper-like skin gets incredibly difficult to remove once the chestnuts have cooled down. I've got tips on how to peel them lower down in this article.
How to Roast Chestnuts in an Oven
(Scroll all the way down for a printable recipe!)
Roasting chestnuts in an oven is pretty simple. Simply place prepared chestnuts in a single layer on a sheet pan with the X facing up, then roast at 425°F until they smell nutty and the shells start to peel back where you scored them.
I've found that roasting chestnuts for about 15-20 minutes works for the large imported chestnuts that I find in most groceries. The smaller local chestnuts only take about 7-10 minutes though.
It can take a bit of trial and error to figure out how long you need to cook the chestnuts for in your specific oven. Try cooking just a few at first so you don't ruin your whole batch.
The chestnuts are cooked when they smell nutty and are HOT to the touch. If your chestnuts are a bit underdone, just pop them back into the oven for a few more minutes.
Peel your chestnuts while they're warm and enjoy.
Be careful not to overcook or burn your chestnuts. Overcooking them will make them so hard that you could confuse them with pieces on a checkers board.
If your chestnuts come out of the oven looking as black as the ones in my photo here, then you've probably overcooked them. Oops!
The shells should only be this dark if you're roasting the chestnuts outside on a fire or over coals.
How to Roast Chestnuts on a Stovetop
Place a heavy skillet over medium heat and place the chestnuts x side up in a single layer in the pan. Roast the chestnuts until they smell nutty and the shells begin to peel back.
Some people recommend adding a bit of oil to the pan, but I've roasting mine dry and they turned out just fine.
This method works almost as well as roasting the chestnuts on a tray, except that I've found that it takes at least 10 minutes longer for the chestnuts to cook.
Again, peel your chestnuts while they're quite warm. See below for tips on how to do this.
You can also use a special chestnut pan to cook the chestnuts on your stovetop. This kind of pan has holes on the bottom, which is supposed to allow steam to escape resulting in a better-roasted chestnut. I've never used one of these before, but I kind of want one...
How to Roast Chestnuts Over Hot Coals
Roasting chestnuts over hot coals is my new favourite way to prepare them! They take on the same charred smokey flavour that you'd get if you roasted them over an actual fire, but you can easily do this on a charcoal barbecue or charcoal fire pit.
I used my mom's DIY concrete fire pit. She just lays charcoal in there with wax fire starter pellets and it works really well.
I used a seasoned cast iron pan, so I was able to nestle the pan right into the coals. If you're using a barbecue that has a grate over your coals, you can use cast iron or use that chestnut pan with the holes that I mentioned earlier.
To get started, light your charcoal. Lump charcoal is great, but you can use briquettes or the embers from a wood fire as well. Avoid using any chemical starter fluids that could alter the taste of your food. I like using wood and wax starters instead.
When we made this batch, we let the charcoals get white hot and ashy before we started cooking. You're looking for a medium-high heat, but if it's really cold and windy out, you may need to a hotter temperature for your chestnuts to roast properly.
Again, you want to place the chestnuts onto the pan in a single layer with the x side up. Then either nestle the pan into the coals (if using a seasoned cast iron pan), or place the pan on the barbecue grate.
Give the pan about 5-7 minutes to heat up (with the chestnuts in it) for your first batch. Once hot, the chestnuts will take about 4-10 minutes to cook, depending on their size.
Stir the chestnuts every couple of minutes of so to help them roast evenly. If it's very windy out, you may want to use a lid to keep the heat in the pan.
CAUTION: The handle of your pot will get hot. Please wear heat proof gloves so you don't accidentally burn yourself.
My first batch of tiny chestnuts took about 9 minutes to cook, but my second batch took only 4 minutes. These were extra small though - about the size of a hazelnut.
Once cooked, remove the chestnuts from the heat or they will burn. Peel and enjoy while they are still warm.
How to Peel Chestnuts:
If you want to get the shells and the bitter paper-like membrane off of the chestnuts, you must peel them when they're still very warm. The hotter they are, the easier they will be to peel.
Unfortunately, as chestnuts cool the membrane begins to stick to the flesh of the nut. Once the chestnuts have cooled completely, you may find that the membrane is down right impossible to get off.
My trick for handling hot chestnuts is to use an old kitchen towel. I take one end of the towel and cover my left hand, and place the chestnut in that hand. Then, I use the other end of the towel in my right hand to peel off the shell.
Not only does the towel protect my hands from the heat, but I'm less likely to cut myself this way too.
I can't tell you how many times I've cut my fingers on sharp bits of chestnut shells. It's not fun, especially when the shell goes under your fingernails...
Well, on THAT happy note (sorry!), I hope you've found this article useful.
Despite everything I've told you here, the reality is that there is no "correct" method for roasting chestnuts. This is because not all chestnuts are the same. They come in different sizes, some have membranes that go through the flesh or the nut, and it can be difficult to figure out how old your chestnuts are.
Just start cooking one small batch at a time, and soon enough you'll figure out what works best for the chestnuts in your area. If you have any tips or tricks on roasting chestnuts, leave them in the comments below. I'd love to hear from you 🙂
Good luck, and happy cooking!

This was a really fascinating post, Shareba. I've never known how to cook chestnuts and found it really interesting (also liked the what not to do sections with the old nuts and burning the chestnuts). I'm now off to google exploding chestnuts, as I'm a little curious... hehe.
Shareba Abdul
Ha! If you find any good videos, be sure to share them with me 😛

Years ago we tried to roast whole chestnuts in our fireplace. After cleaning up the mess that ensued we forgot about making them. Lately I've been wanting to have another go at them so I'm very happy to find your post. Thanks Shareba!
Shareba Abdul
I hope it's helpful Bernice!
Gabrielle @ eyecandypopper
what?! oh my gosh, I've never roasted chestnuts but this is awesome! I kind of want my own chestnut tree now..... 🙂
maria
I have always had a fascination with chestnuts. In fact, growing up Italian meant my whole family was obsessed with chestnuts! We would use them in baking, cooking and for snacking. In fact, i just roasted a few pounds in order to make one of my favorite Christmas desserts. Great post, thanks for sharing the love on chestnuts 🙂
Charlotte
I always see these at the grocery store but am always too intimidated to cook them. Thanks for the tips for roasting them! I'll have to pick some up next time I see them.
Shareba
Just be careful when you're scoring them, and you should be ok! Let me know how they turn out 🙂

Jane Fuller
Hi and thanks for the beautiful page. I soak almonds, then drive off the water in a very low temperature oven. This with the understanding that letting the nuts (seeds) do their initial step, absorbing water, enhances their nutritional value. They come out softer and crunchier too. I've just pealed one chestnut and put it in warm water. I'll see if it plumps up as the almonds do. Do you know anything about this? Thanks. Jane in Vermont, usa.
Shareba
Hi Jane, thanks for your comment. I have soaked shelled almonds and roasted them, and that works really well. However, I've never soaked shelled chestnuts. I have soaked the chestnuts with the shell on before baking, which can sometimes make them easier to peel. I would be interested to know how soaking the peeled chestnuts worked out for you. Please let me know!
Jane Fuller
Hi, I will let you know. Thanks for your post and best wishes for the lovely season of candles and bright colors, if not the great Christian drama.
Shareba
Best wishes to you too Jane, take care 🙂
Sandy
I love all of your ideas. Great information. I am getting my family an Air Fryer for Christmas. After doing a little research, it looks like it is possible to roast them using this appliance. Going to try it so we will see. Wish us luck!
Shareba
Good luck Sandy!! Let me know how they turn out in the air fryer!
Andy
Some great tips. Thanks!

Pat Borecky
Hi , I washed my chestnuts then roasted in oven 18 min just like the instructions. I put in towel then proceeded to peel open - very hard to do & had to scape the mealy out ( used a strawberry hull spoon after trying a few knives) No such thing as a full nut. Now I ave a bowl of mealy chestnut flour which taste terrible.
Do I need to bake the flour then process for cooking? or have I wasted 3 hrs. I have another huge batch some in fridge, some freezer. What to do?
Txs Pat
Shareba
Hey Pat,
Were your chestnuts quite small? If so, 18 minutes was probably ok, but I do recommend in my instructions that you roast for about 25 minutes for average-sized chestnuts.
That being said, even when cooked properly, you will sometimes find that the chestnuts are not good. They can be mouldy, or dry, or hard to peel and they just fall apart. It's the unfortunate nature of chestnuts. If you get a bad batch, you won't know until you try to cook them. You can't do anything with the broken pieces of they aren't cooked through, from my experience.
I have the best results when I buy chestnuts that are grown locally, instead of buying what we import from China or Italy. We don't know how old the nuts are when we buy the imported stuff, so it's always a bit of a gamble. Sometimes they turn out fine, sometimes they just don't and it's very disappointing. I try to cook the imported ones as soon as I get them home, but even then sometimes they are already too stale and I won't know until I try to cook them.
I'm sorry that you've had a poor experience with roasting your chestnuts though. I hope your next batch turns out better.
Ricardo W Jordan III
Awesome...I've never tried roasting chestnuts but have lately had the desire to do so. Chestnuts grow all over in my hometown and are hard to walk on, you can twist an ankle if you're not careful when going for a walk. I do want, more than anything else, to smell the aroma they give off in an attempt to get in the holiday spirit. Thank you for the info.
Shareba
Ah that's so cool! If chestnuts grew all over the place like that here, I'd eat them all the time! I hope you do get a chance to roast a bunch this holiday season, they really do smell quite lovely.
Betty Cutler
Just remember these are NOT horse chestnuts that are SO often seen here in Ontario. I don't know the proper name for the edible ones...we just called them English. Betty
Barry
Hi. Just read your great piece on chestnuts.
My favourite winter food.
Here, walking around the west end shops, street vendors sell chestnuts that they cook on portable braziers.
The smell and taste is awesome even though they are quite expensive and the portions get smaller each year 😉
Shareba
I'm glad you liked my blog post Barry!
I wish we had street vendors selling chestnuts here - sounds a lot more tasty than just hot dogs!
I do love the smell of them, I can't imagine what it must be like being able to walk around that smell! It's a shame they are becoming more expensive where you are though.
Rachel Smolen
This post is wonderfully informative! Thank you so much for going to the trouble of detailing all aspects of cooking the lovely chestnut. I just went apple and pumpkin picking in southern California and stumbled upon chestnut picking as well. To say I was thrilled would definitely be an understatement!!!! But my question is this; what are your favorite recipes and favorite preparations of chestnuts? I’ve only ever made chestnut stuffing (GF) and once a kind of french holiday rolled cake with chestnut cream..? But we didn’t start with the raw goods we had some sort of jarred product I think. But I love the idea of little red henning it starting with the chestnuts we smashed and twisted under the chestnut trees and I carefully peeled out from those spiky burrs! I have exactly 1 pound of them! What to make!!!!????
Shareba
Hi Rachel, I'm glad you found the post useful! I wish chestnut picking was a thing around here, I'd definitely give that a try!
As far as my favourite chestnut recipes... honestly, I just eat them roasted with a ton of salt and butter. I've heard they work well in stuffing though, like this one: https://www.bbcgoodfood.com/recipes/3170/chestnut-bacon-and-cranberry-stuffing.
I really should experiment with them more though!
Lenny Josephs
Thanks Shareba. Your information is very useful and accurate.
I roast chestnuts over an open fire every Christmas Eve (just like the song)
I was looking for alternate ways to eat them and will definitely try the salt and butter. One way I like to eat them is by putting them in a cast iron pan with some Grand Marnier and flambeing in fire to get the sweet orange flavour to coat them. Its quite delicious!
Lenny
Shareba
Oh that sounds delicious! I'll have to try that if I can get my hands on some decent chestnuts this season. The last few I got from the grocery was awful, and one of the local farmers I know said her crop was poor this year. Such a shame. Anyhow, thanks for the comment, and I hope you enjoy eating them with salt and butter!
Peter Shepherd
Well Done!! This got me through my first successful chestnut roasting perfectly. Among other things, you helped me be confident in the face of some bad chestnuts (It's not my fault), and happy with the successful ones. I used store-bought Italian imports, but I'm going to keep my eyes out for local (central Ontario) chestnuts next year. Thanks.
Shareba
Hi Peter, I'm so glad you found my post helpful! Roasting chestnuts is one of my favourite things to do in the winter months, but some years it's so hard to get a good batch! My farmer friend in Ontario said her crop was poor this year, but hopefully next year will be better.
Marjorie
Thanks for this great info on roasting chestnuts. Just off to have a go with some my son bought from our local supermarket in Highlands of Scotland! Will let you know how we get on.

Hello! After twenty years of roasting our chestnuts in the microwave our microwave bit the dust. (Cut an x in the top, arrange on microwave safe plate, cover with Saran Wrap and cook for two minutes). Never caught any on fire as the Saran Wrap keeps them nice and moist! While we await delivery of a new one, I found your recipe on how to roast them the regular way. This worked very well for me though we cooked longer as they were rather large. Thanks for the recipe! Delicious!
Shareba
That's good to know about the saran wrap! I think part of the my problem is that I was re-heating already cooked chestnuts in the microwave, and they don't have much moisture left after roasting.
I'm so glad that my recipe worked for you! 😀
Julie F
We used to have roasted chestnuts when I was a kid, on Boxing Day we would go to the market square to watch the hunt leave and we would always buy a bag of roasted chestunts to help keep us warm!
Shareba
What a lovely tradition! I wish roasted chestnuts were still a street food here.
Moksha
Thank you!!! You opened my chestnut 🌰 chakra ,,,, all the best, moksha

Happy to help!
Jane D Clark
I am going to roast some in the oven tonight. Mom used to get some every year and roast when I was little, now I am doing so for my grandson. Will bring back memories from 55plus years!!
Shareba
What a wonderful tradition to uphold! I hope you and your grandson get to do this together for years to come 🙂
T. Furlong
Been experimenting with various recipes for years. This is the best. Hint, use gardening gloves with rubberized grips to pull the chestnuts right out of the oven. Protect from the heat and just rub the membrane off.
Shareba
I'm glad that my recipe worked for you, and thank you so much for the tip about the gloves!

Hi
I have fond memories of both walking through the woods with my Dad, finding and eating chestnuts raw. The other is buying chestnuts from stalls in London streets where they have just cooked chestnuts over hot coals. The skins often blackened but peel off easily as we rub the chestnuts with our hands, warming them in the process. A great winter snack in cold weather.
Chukwuma Nma
Thanks for your time.
I'm an African, and I want to try it out
Shirley
great article! Chestnut stuffing has always been a staple at holiday dinners. After my mom passed away my dad made it. Sadly he passed in January and I was trying to make it for Christmas. 4 pounds of nuts from Sobeys and 98% are moldy. Thanks for the tip about local Niagara chestnuts, I am in Niagara and will source local from this point forward.
Thanks again for the info it was most helpful
Shareba
Hi Shirley, I'm so sorry for your loss. Hopefully you will be able to find some good chestnuts in your area! You can also try reaching out Elisabeth at [email protected]. She sells chestnuts at GTA farmers markets when she has them, and might be able to point you in the right direction. I hope this helps! Merry Christmas 🙂
