Air fryer chestnuts are the fastest way to get that sweet, buttery, street-vendor roasted chestnut flavor at home. Score them, soak them for 10 minutes, air fry for about 15 minutes, and they come out tender inside with shells that curl right back. No open fire, no oven, and no fighting with stubborn skins.

The secret to chestnuts that actually peel is in three small steps most recipes skip: a deep enough score, a quick hot-water soak, and a 5-minute steam in a towel after roasting. I’ll walk you through each one, plus exactly how long to air fry chestnuts by size and the settings I use in the Ninja Foodi.

If you love roasting nuts in the air fryer, you’ll also want my air fryer roasted almonds and roasted pecans in the air fryer. Chestnuts are a little different, though. They’re soft and starchy inside, more like a sweet potato than a crunchy nut, so they need their own method.

Why You’ll Love Roasting Chestnuts in the Air Fryer

  • Done in about 25 minutes total. That’s roughly half the time of oven-roasted chestnuts, with no preheating a big oven.
  • Shells that actually peel. The soak-and-steam method loosens both the hard shell and the papery inner skin.
  • Even roasting. Circulating hot air cooks every chestnut the same, so you don’t get a mix of burnt and raw.
  • One ingredient. Just fresh chestnuts, with a sprinkle of salt if you like.
  • A holiday tradition made easy. Perfect for Thanksgiving, Christmas Eve snacking, or chopping into air fryer stuffing.

Ingredients and Equipment

  • Fresh chestnuts (1 pound): Look for shiny, heavy, firm nuts in the shell. About 1 pound feeds 4 people as a snack.
  • Flaky sea salt (optional): A pinch after roasting brings out their natural sweetness.
  • Butter (optional): A little melted butter tossed with the peeled chestnuts makes them taste like a holiday treat.

You’ll also need a sharp paring knife or a serrated knife for scoring, a bowl for soaking, a clean kitchen towel, and any basket-style or oven-style air fryer.

Don’t confuse these with water chestnuts. Water chestnuts are a crunchy aquatic vegetable, best in recipes like air fryer bacon wrapped water chestnuts, while true chestnuts are a tree nut with a soft, sweet center.

How to Choose Good Chestnuts

  • Good chestnuts feel heavy for their size and have glossy, tight shells with no give when you press them. Skip any that rattle, feel light, have tiny holes, or show mold near the pointed tip, since those are usually dried out or spoiled.
  • When you soak them (step 2 below), toss any that float to the top. Floaters are often hollow or rotten inside. Fresh chestnuts are in season from October through December, and they keep about a week in the fridge in a paper bag.

How to Air Fry Chestnuts (Step by Step)

Scored chestnuts soaking in a bowl of hot water before air frying

Step 1: Score the chestnuts. Lay each chestnut flat side down on a cutting board. Cut a deep X across the rounded side, slicing through the shell and the thin inner skin. A shallow cut is the number one reason chestnuts explode or won’t peel.

Step 2: Soak in hot water. Put the scored chestnuts in a bowl and cover with very hot tap water or just-boiled water. Let them sit for 10 minutes. Remove any that float, then drain well.

Step 3: Preheat the air fryer. Set it to 400°F (200°C) for 3 minutes.

Step 4: Arrange in a single layer. Place the chestnuts cut side up in the basket without crowding. Cook in batches if needed. Cook for 12 to 15 minutes, shaking the basket halfway through. They’re done when the X has curled open and the flesh inside looks golden and smells nutty.

Step 5: Tip the hot chestnuts into a clean kitchen towel, wrap them up, and let them sit for 5 minutes. The trapped steam loosens the skins. Squeeze each chestnut gently so the shell cracks further, then peel back the shell and inner skin together.

How Long to Air Fry Chestnuts

Most chestnuts take 12 to 15 minutes at 400°F in the air fryer. Size makes the biggest difference, so start checking a few minutes early the first time.

Chestnut sizeTemperatureTimeNotes
Small (under 1 inch)400°F / 200°C10–12 minCheck at 10 minutes
Medium (about 1 inch)400°F / 200°C12–15 minThe standard for this recipe
Large (over 1¼ inches)400°F / 200°C15–18 minShake twice for even cooking
Gentler roast, any size350°F / 175°C17–20 minLess risk of scorched edges

Basket-style air fryers usually run hotter than oven-style models. If your chestnuts look dark before the X opens, drop to 350°F and add a few minutes, the same way you’d adjust for softer nuts like air fryer toasted walnuts.

How to Air Fry Chestnuts in the Ninja Foodi

In a Ninja Foodi, use the Air Crisp function at 390°F for 12 to 15 minutes with the crisping lid closed. Place the scored, soaked chestnuts in the Cook & Crisp basket in a single layer and shake once halfway through.

The Foodi’s basket is deeper than most air fryers, so don’t pile chestnuts on top of each other. For a full pound, cook in two batches. In a Ninja dual-basket air fryer, split the chestnuts between both baskets and use Match Cook so they finish together.

While the Foodi is out, it’s a great time to make a holiday side too, like this Ninja Foodi baked sweet potato.enly roasted.

Hot roasted chestnuts wrapped in a kitchen towel to steam before peeling

How to Peel Roasted Chestnuts Easily

Peel chestnuts while they’re still warm. Once they cool, the inner skin (called the pellicle) sticks to the nut again and gets bitter and hard to remove.

After the 5-minute towel steam, press each chestnut between your fingers until the shell cracks along the X. Pull the shell back from the cut, then rub off any papery skin left behind. If a few start getting stubborn, put them back in the air fryer for 1 to 2 minutes to warm up, then try again.

If you’re peeling a big batch for a recipe, keep the unpeeled chestnuts wrapped in the towel and work a handful at a time.

Tips, Troubleshooting, and Storage

Why did my chestnuts explode? The score wasn’t deep enough. Steam builds up inside the shell and needs a way out, so make sure your X cuts through both the shell and the inner skin.

Why won’t my chestnuts peel? They’re either undercooked, cooled too long, or weren’t steamed. Return them to the air fryer for 2 minutes, then wrap them in a towel for 5 minutes before peeling.

Why are my chestnuts burnt or dry? The basket was overcrowded, the heat was too high for your model, or they skipped the soak. Try 350°F and always soak first.

How to store: Keep peeled roasted chestnuts in an airtight container in the fridge for up to 4 days. For longer storage, freeze them peeled in a freezer bag for up to 3 months.

How to reheat: Air fry at 350°F for 2 to 3 minutes until warm.

Ways to Use Roasted Chestnuts

Air Fryer Chestnuts FAQs

How long do you air fry chestnuts? Air fry chestnuts at 400°F for 12 to 15 minutes, shaking the basket halfway. Small chestnuts may be done in 10 minutes, and large ones can take up to 18.

What temperature do you air fry chestnuts at? 400°F (200°C) gives the fastest roast. If your air fryer runs hot or the shells darken early, use 350°F for 17 to 20 minutes.

Do you have to soak chestnuts before air frying? It’s not required, but a 10-minute hot-water soak adds steam inside the shell, which keeps the nuts moist and makes them much easier to peel.

Do you need to score chestnuts before air frying? Yes. Without a cut, steam can’t escape and the chestnuts can burst inside your air fryer.

Can you air fry chestnuts in a Ninja Foodi? Yes. Use Air Crisp at 390°F for 12 to 15 minutes in a single layer, shaking once halfway through.

Can I air fry frozen or pre-peeled chestnuts? Pre-peeled, vacuum-packed chestnuts are already cooked, so just warm them at 350°F for 3 to 4 minutes. Frozen in-shell chestnuts should be thawed first, and they’re often harder to peel than fresh.

Are roasted chestnuts healthy? Chestnuts are much lower in fat than most nuts and are a good source of fiber and vitamin C, so they make a lighter holiday snack.
