Place hatch chiles on a baking sheet in a single layer.

Turn your oven on the "broil" setting. Place baking sheet under the broiler for 6-8 minutes, until the skin has blackened.

Remove baking sheet from the oven and flip over each pepper using tongs. Bake an additional 6-8 minutes, until this side of the pepper has also blackened.

Carefully pull the skin off each pepper and store in Ziploc bags or vacuum seal and store in the freezer until ready to use.
