Easy Tuna Casserole with Egg Noodles

Tuna Casserole with Egg Noodles

This classic American casserole blends simple pantry staples into one hearty dish. Cooked egg noodles are combined with canned tuna, peas, and a creamy sauce—often made with condensed soup and milk—then baked with a crispy topping. It’s quick to assemble, budget-friendly, and a favorite for both kids and adults.

Ingredients

  • 2 cans (5 oz each) tuna, drained and flaked

  • 3 cups cooked egg noodles

  • 1 can (10 oz) cream of mushroom soup
