Can you roast chestnuts in foil?

Online Answer
Place a large sheet of foil on a rimmed baking sheet. Place chestnuts, flat side down, on a work surface. Using a utility knife or a sharp paring knife, carefully cut through the shell on the rounded side of each chestnut to score an X. Soak in a bowl of hot water for 1 minute (this helps them steam while roasting).
