A true classic comfort dish, Tuna Noodle Casserole brings creamy nostalgia with every bite. It’s that easy weeknight meal you turn to when you need something hearty, cozy, and crowd-pleasing. Loaded with tender egg noodles, flaky tuna, sweet peas, and a crunchy topping, it hits all the right notes of texture and flavor.

What Kind of Noodles Work Best in Tuna Noodle Casserole?

Wide egg noodles are the go-to for this dish because they soak up the creamy sauce without getting too mushy. Their gentle curve holds bits of tuna and vegetables perfectly. However, you can substitute with rotini or fusilli if that’s what you have on hand—just cook them al dente to avoid a soggy bake.

Ingredients for the Tuna Noodle Casserole

• Egg noodles: These soft, twisty noodles provide a tender bite and are perfect for casseroles.
• Canned tuna: Choose a high-quality tuna in water or oil; it’s the protein backbone of the dish.
• Cream of mushroom soup: Adds rich creaminess and binds everything together with umami flavor.
• Frozen peas and carrots: For a pop of sweetness and color.
• Onion: Diced finely, it enhances the savory depth of the casserole.
• Cheddar cheese: Melted into the mix for a gooey, cheesy base.
• Sour cream or Greek yogurt: Adds tang and creaminess.
• Potato chips or breadcrumbs: For that irresistible crunchy topping.
• Salt and pepper: Essential seasoning.
