Thereโs nothing like the aroma of freshly roasted chestnuts to make a home feel warm, festive, and a little bit magical. This easy method shows you how to recreate that winter-market flavor using just an air fryer and a quick hot-water soak, so the shells peel effortlessly and the insides turn tender, sweet, and perfectly caramelized. No fire, no mess, and no special equipment, just simple steps that guarantee delicious results every time. Whether youโre snacking, entertaining, or recreating holiday memories, roasted chestnuts donโt get easier or more nostalgic than this.
Roasted chestnuts are a winter tradition across Europe, filling Christmas markets and streets with that sweet, woodsy aroma everyone recognizes. From Italian caldarroste to cozy vendors in Switzerland, France, and Germany, theyโre sold hot in paper cones and enjoyed as a simple, comforting treat. Chestnuts reach their peak from November to January, which is why theyโre so strongly linked to holiday season food and festive markets.
The best part? You can recreate that street-vendor experience right at home.

Ingredients
Iโm using Italian chestnuts because theyโre naturally sweet, creamy, and roast beautifully. They also peel more easily, especially after a quick hot-water soak. And in Switzerland, Italian chestnuts are the ones youโll find most often in supermarkets, so theyโre the perfect choice for getting that classic street-vendor flavor at home.
- Italian chestnuts
- Hot water
See recipe card for quantities.
Instructions
- Rinse chestnuts and pat dry. On the rounded side, use a sharp paring knife to cut a confident X through the shell and inner skin. Keep fingers behind the blade.
- Place scored chestnuts in a heatproof bowl, cover them with boiling water, and let them soak for 60 seconds. Then, drain them well.
- Arrange the chestnuts in a single layer, X-side up, in the air fryer.
- Roast the chestnuts for 20 min, shaking once or twice at 175 ยฐC / 350 ยฐF.
Hint: Be confident with your scoring. Cut a clear X through both the shell and the papery skin underneath; shallow cuts wonโt open, and the nuts wonโt peel easily.
Equipment
As you have noticed from the instructions you donโt need much to make roasted chestnuts at home. An air fryer does all the work that hot coals and cast-iron pans used to do, giving the nuts that dry, even heat they need. A sharp paring knife is important for scoring the shells cleanly, and a heatproof bowl is handy for the quick hot-water soak that helps them peel. After roasting, a kitchen towel or paper bag is all you need to trap a bit of steam and make peeling easier.
Storage
Roasted chestnuts are always best enjoyed fresh and warm; thatโs when theyโre soft, sweet, and the shells slide off easily. If they cool down, the skin tightens again and becomes harder to peel, so try to shell them while theyโre still hot. If you have leftovers, keep the peeled chestnuts in an airtight container in the fridge for 2โ3 days, or freeze them for up to a few months. You can reheat them gently in the air fryer or a warm oven, but nothing beats them straight out of the steam towel.
Top Tip
Start checking the chestnuts a few minutes before the timer ends. Every batch is a little different, and once the shells curl back and the nuts smell sweet and toasty, theyโre ready. If you roast them too long, they dry out and lose that soft, creamy texture. Pull the ones that are done and let the other ones cook just a bit longer.
FAQ
Look for chestnuts with smooth, shiny shells and no cracks or holes. Pick them up, fresh chestnuts feel heavy for their size because theyโre full of moisture. When you press them gently with your fingers, they should feel firm, not soft or spongy. If the shell gives in or feels hollow, the nut is likely dried out. Another easy test: place them in water. Fresh chestnuts sink; old or spoiled ones often float.
Chestnuts build steam inside the shell as they roast. If you donโt score them, they can burst in the air fryer or oven, making a mess (and a loud pop!). A firm X through the shell and inner skin lets steam escape and makes peeling easier.
Chestnuts vary in size and moisture. If some are ready early, pull them out and let the larger ones roast a bit longer. Lower the temperature slightly and extend the time for big chestnuts so the centers soften without burning the shells.
A quick hot-water soak helps loosen the shells and the thin inner skin. When the chestnuts roast, the added moisture creates gentle steam under the shell, so it curls back and peels easily. Without soaking, the skin can stick and peeling becomes frustrating.
A short hot-water soak helps the shell and inner skin loosen just enough so they peel easily after roasting. More than 60โ90 seconds starts pushing moisture into the nut itself, which can make the texture mushy or mealy instead of sweet and creamy. The goal is a quick boost of steam under the shell, not waterlogged chestnuts, so a short soak is all you need.
Edible chestnuts are easy to find in supermarkets, farmersโ markets, and specialty shops from October to January, when theyโre in season. Look for loose chestnuts sold by weight or packaged in mesh bags.
Plain chestnuts (no salt or seasoning) are generally safe for dogs in very small amounts, but avoid giving them chestnuts in shells as it's a choking hazard. Never give chestnuts coated in salt, sugar, or chocolate.
Tiny holes mean insects or larvae were inside. This happens more with older or improperly stored chestnuts. If you see holes, compost them, donโt roast.
Theyโre ready when the shells have curled back at the score marks and the nuts smell sweet and toasty. The flesh should be soft, golden, and slightly caramelized, not pale or firm. If you gently squeeze one (with tongs or a towel), it should feel tender, not hard in the center. If some are larger and still firm, leave them in the air fryer for a few extra minutes while you pull out the smaller ones.

- Start checking at 15 minutes: shells should curl back, nuts smell sweet/toasty.
- Pull any chestnuts that open early and give the stubborn ones 2โ3 more minutes.
Steam for easy peel
- Transfer immediately to a clean towel or paper bag. Close and rest 5โ10 minutes to trap steam. Peel while hot (shell + papery skin).
