To reheat a fully cooked casserole, preheat your oven to 350°F (175°C). Cover the casserole with aluminum foil to prevent the top from burning or drying out. Heat it for about 20-30 minutes, or until it's heated through. For casseroles with a cheese or breadcrumb topping, remove the foil for the last 5-10 minutes of baking to allow the top to become crispy and golden.
