Roasted chestnuts: oven, microwave and air fryer, with a trick for peeling them

Ingredients

• 1 kgchestnuts

Instructions

1. 1

   Score the chestnuts

   Use a knife to cut a cross into the base of each chestnut or across its rounded side.

2. 2

   Allow for variation

   Treat the cooking times below as a guide: chestnut size and appliance performance can vary, so adjust the time by a few seconds as needed.

3. 3

   Use an air fryer

   Cook the chestnuts at 180°C for 15 minutes.

4. 4

   Use a conventional oven

   Cook at 200°C with top and bottom heat for 20–25 minutes, depending on the size of the chestnuts.

5. 5

   Use a microwave

   Cook at 1,000 W for 3 minutes.

6. 6

   Peel while warm

   As soon as the chestnuts are cooked, cover them with a cloth to keep them warm and start peeling. They are usually easiest to peel while hot.

7. 7

   Loosen cold skins

   If some chestnuts have cooled, or their inner skin is stuck, put them in a bowl and cover them with boiling water. This brief blanch can make the chestnuts and their inner skins easier to peel.

What are roasted chestnuts?

Roasted chestnuts are a familiar autumn snack across parts of Europe, including Spain, where they are enjoyed as the weather turns cooler. Their sweet, earthy flesh softens as it cooks, while scoring lets steam escape and helps the shells open.

This recipe offers three ways to cook them, so you can use an air fryer, oven or microwave. The key is to score each chestnut first and peel it while it is still warm.

Nutrition and macros by portion

The nutrition label shows one serving as written: 533 calories, 9g protein, 112g carbs, 3g fat.

Chestnuts provide most of this dish’s carbohydrates, with a smaller amount of protein and very little fat; there are no added ingredients contributing extra fat. Pair a portion with a protein-rich food and vegetables for a more balanced plate.

Scoring the chestnuts

The cut: Make a clear cross at the base or on the rounded side of each chestnut. Take care with the knife, as the shells are hard and the chestnuts can roll.

Choosing a cooking method

Air fryer: The recipe gives 15 minutes at 180°C. Chestnut size and air-fryer performance affect the result, so use the time as a guide.

Conventional oven: Roast at 200°C with heat from above and below for 20–25 minutes. Larger chestnuts may need more time than smaller ones.

Microwave: The method specifies 3 minutes at 1,000 W. Follow the scored-chestnut preparation, and check how easily the shells open before peeling.

Knowing when they are ready

The timing: Chestnuts are different sizes, and appliances do not all cook alike, so the stated times are approximate. Look for shells that have opened at the cuts, then check one chestnut before peeling the rest.

Peeling without frustration

While warm: Cover the cooked chestnuts with a cloth and peel them soon after cooking; warmth generally makes both the shell and inner skin easier to remove.

If they cool: Place stubborn chestnuts in a bowl and cover them with boiling water. This brief soak can help loosen the inner skin as well as the shell.

Serving roasted chestnuts

Serve them warm as a simple snack, or add peeled chestnuts to a seasonal meal. Their naturally sweet, starchy flavour works well alongside savoury dishes such as roast vegetables or greens.

Recipe notes & tips

• Make a definite cross in every shell so the chestnuts can open as they cook.
• Keep the chestnuts covered with a cloth after cooking to slow cooling while you peel them.
• Use the time as a starting point, since chestnut size and appliance performance vary.
• Test one chestnut for tenderness before peeling the whole batch.
• Handle the knife carefully when scoring the hard, rounded shells.

Variations

• Serve savoury: Pair the peeled chestnuts with roast vegetables or greens.
• Add to stuffing: Chop peeled chestnuts and mix them into a savoury stuffing.
• Make a purée: Mash peeled chestnuts for a simple, soft side dish.
• Choose another method: Use the oven, air fryer or microwave according to the equipment you have.

Common mistakes to avoid

• Skipping the cuts: Unscored shells are harder to peel; cut a cross into every chestnut before cooking.
• Using the time rigidly: Chestnuts and appliances vary; check the result and adjust the cooking time as needed.
• Leaving them uncovered: They cool before peeling; cover them with a cloth as soon as they are cooked.
• Waiting too long to peel: The skins can be more difficult to remove when cold; start while the chestnuts are warm.
• Forcing off a stuck inner skin: Soak the chestnut in a bowl of boiling water to help loosen it.

How to store

For easiest peeling, serve and peel the chestnuts while warm. If you have leftovers, cool them and refrigerate in a covered container for up to 3 days; reheat briefly until warm, then peel if needed.
