Chestnuts roasting on an open fire! It's a song I'm sure you're familiar with—those soothing melodic tones certainly spread holiday cheer. But what exactly does it take to roast chestnuts on an open fire? Better yet, how in the world do you roast chestnuts?

If you've ever been curious about how to roast chestnuts, never fear, we're here to show you! Roasting chestnuts in the oven is actually easy to do.

Buy dry chestnuts

This may seem obvious, but for this recipe, you'll need dry chestnuts! You can actually buy wet chestnuts in the store that have already been roasted and shelled. These types of chestnuts usually come in a jar, which are not the type you want. The type of chestnuts you want to buy typically pop up in the produce section of a grocery store around the holiday season.

Here's a step-by-step guide on roasting chestnuts.

Makes 20-30 chestnuts


1 lb. chestnuts
1 tbsp butter, melted
1 tsp salt
1 sprig rosemary

How to Make It

Cut an 'X' into the round side of the chestnut

Typically chestnuts have a round side and a flat side, so for this step, lay each chestnut down on the table on their flat side. Using a serrated knife, carefully cut an 'X' into the chestnut. You'll want to cut in pretty deep to make sure you cut through both skins of the chestnut (the outer shell and the inner skin), or it will be impossible to peel them later.

Soak the chestnuts in hot water

Heat up some water on a kettle, or in a microwavable bowl, until the water is very hot. Soak the chestnuts in hot water for 3 minutes.

Pat them dry

In another bowl, mix together the chestnuts with the melted butter, salt, and rosemary.

Spread the chestnuts on sheet pan

Make sure the 'X' cut side of the chestnut is facing up before placing them in the oven.

Roast in the oven for 15-20 minutes

Bake at 425 degrees Fahrenheit in the oven for 15 to 20 minutes. The easiest way to know if the chestnuts are done is if you see they are starting to peel. If they peel on their own a bit, it makes it easier to peel them with your hands later. But watch out! If you leave them in too long, they may actually explode. So keep an eye on them!

"Steam" them in a bowl

As soon as they are done, immediately transfer the chestnuts to a bowl and cover them in a towel to "steam" them. This will make them easier to peel. Leave them in the bowl with the towel for at least 5 minutes.

Peel while warm

The chestnuts will still be pretty warm after the steam, but peeling them warm is much easier than peeling them cold! Some of the nuts may not come out as easily as others, but if you're simply opening them up for a fun winter snack, the shape shouldn't matter as much.
