Here is my method of roasting chestnuts in an oven.

Score a line with a sharp knife on the flat side of the chestnut. This allows steam to escape while the chestnut is roasting. If you do not, chestnuts will explode in your oven! Some folks say to score an X on the flat side, but I find that a line works just as well and saves time if you have a lot of chestnuts to roast.

Arrange chestnuts on a baking tray and put in an oven at 200°C, for about 30 minutes. Check regularly.

Allow chestnuts to cool a little before taking off the shells. They can be fiddly to peel, so unless you want whole chestnuts, try squeezing the shell in half and scooping out the contents with a teaspoon.
