Chow time: Reheat and serve Heat the enchiladas: If you're feeding the whole family or a crowd, the enchiladas can be reheated directly from the refrigerator or freezer in the casserole dish they were baked in. Preheat the oven to 350˚F. Keep the foil on the dish and reheat for 20-30 minutes (refrigerated) or 45 minutes (frozen), until the enchiladas are warmed through. If you'd rather reheat individual servings, enchiladas in small microwave-safe containers can be zapped in the microwave for 2-3 minutes or reheated in a toaster oven for 10-15 minutes. Eat up: Serve the enchiladas with sour cream, guacamole, and/or salsa.
