How Do You Heat Up Tuna Casserole?
To heat up tuna casserole, start by preheating your oven to 350°F (175°C) and transferring the casserole to an oven-safe dish. Cover the dish with foil and bake for 20-25 minutes or until the casserole is heated through. Alternatively, you can microwave the casserole on high for 2-3 minutes, stirring halfway through. Make sure the internal temperature of the casserole reaches 165°F (74°C) before serving.
