You can freeze your tuna casserole in three ways: - Without the noodles - With precooked noodles - Finish the recipe
If you choose to freeze your tuna noodle casserole, you have to remember to thaw it for 24 to 32 hours first then let it stand for 30 minutes at room temperature before baking.
To reheat your tuna casserole using the oven, start by preheating the oven at 350F. Cover the top of your casserole with aluminum foil before popping it in the oven.
To prevent your casserole from drying out, put a small microwave safe cup with a bit of water in the microwave along with your tuna casserole. Microwave for 2 to 3 minutes.
