Step 1

Rinse and dry the chestnuts well.

Step 2

With a sharp knife (like a paring knife), carefully score the chestnuts in the center, making a line going across the round side, just piercing the inner skin and not the chestnut itself.

Step 3

Scoring is an important step, because chestnuts expand as they roast.

Step 4

Optional: Soak the scored chestnuts in a bowl of hot water for one minute to help with steaming. Drain and dry them well.

Step 5

Preheat the oven or airfryer 356F / 180C, unless you are using a pan on the stovetop.

Step 6

Oven - cook chestnuts on a lined baking sheet. Shake baking sheet halfway through cooking. Depending on your oven, you may need to flip the chestnuts so they cook evenly. (Approximately 30 minutes).

Step 7

Air Fryer - shake basket to flip chestnuts a couple of times during cooking. (Approximately 30 minutes).

Step 8

Pan - Roast over a medium-low flame, tossing often. (Approximately 10-15 minutes).
