Big Y's Easy Guide to Roasting Chestnuts in the Oven
Start with 1 1/2 pounds fresh chestnuts. Rinse with cold water.
Soak chestnuts in lukewarm water for about 30 minutes to soften the shells.
With a serrated knife, cut an "X" through the rounded part of the shell. This keeps it from exploding while roasting in the oven.
Place chestnuts in a single layer on a cookie sheet.
Bake at 475 degrees for 20-25 minutes or until the shells peel back and nuts are tender.
Mound the nuts in the center of a clean kitchen towel and draw up edges into a pouch.
Squeeze the pouch a few times to loosen shells. Let sit for about 10-12 minutes.
Peel the chestnuts gently to remove shells.
Toss with a little olive oil and salt and enjoy!
