Making roasted red peppers at home is a quick process. The Food Network recommends thoroughly washing the peppers before holding them over a heat source with tongs -- a grill or gas range works best. Turn the pepper until the skin is evenly blistered and blackened on all sides. Place the peppers in a bowl and cover with a plate or plastic wrap to allow steam to further loosen the skin from the pepper flesh. Peppers are then ready to be peeled and seeded.
