How to Make Tuna Mushroom Casserole

Start by cooking the egg noodles according to the package directions. I find that egg noodles are light and perfect for casserole making. After the noodles are cooked combine the noodles, two 6 ounce cans of tuna and the mushrooms in a large bowl.

Combine the milk and the cream of mushroom soup in a bowl. Whisk or stir well to combine. You will want to stir these together completely before combining them with the noodles.

After you have the creamy mushroom sauce combined, you will want to mix it with the noodles.
