Ingredients You Need for Tuna Noodle Casserole
This tuna noodle casserole uses simple ingredients you probably already have in your pantry. Each one plays an important role in the final dish.
Egg noodles (16 oz) or elbow macaroni – These wide noodles hold onto the creamy sauce and keep the casserole hearty and filling.
Cream of mushroom soup (22.6 oz) – This creates the creamy base without needing to make a sauce from scratch.
Canned tuna, drained (2 five ounce cans) – Adds protein and makes this casserole satisfying and budget friendly.
Sweet peas, drained (15 oz can) or frozen peas – Adds color, texture, and a touch of sweetness that balances the creamy sauce.
Crushed potato chips (1½ cups) – The crunchy topping that takes this casserole from good to great.
Cheddar cheese (1 cup, shredded) – For a cheesy topping.
