This tuna pasta bake is pure comfort from the pantry: pasta, canned tuna and peas in a creamy cheddar sauce, baked under a crisp breadcrumb topping.
Canned tuna is one of the least expensive proteins you can keep on hand, and it’s ready whenever you are. With pasta, frozen peas and a quick sauce made from milk and flour, this is a dinner you can make without going to the store.
The sauce is made from scratch in about five minutes, so there’s no canned soup involved.
Ingredients and Swaps
- Pasta: Short shapes like shells, rotini, elbows or penne hold the sauce.
- Tuna: Two 5-ounce cans, drained well. Tuna packed in water or oil both work. Canned salmon or chicken are easy swaps.
- Milk, butter and flour: These make the creamy sauce.
- Cheddar: Sharp cheddar gives the most flavor.
- Peas: Frozen, straight from the freezer. Corn or small broccoli florets work too.
- Breadcrumbs: Plain or panko. Crushed crackers or potato chips make a good topping as well.
Tips for a Creamy Bake
- Undercook the pasta. Boil it 1–2 minutes less than the package says. It finishes cooking in the oven.
- Make the sauce a little loose. The pasta absorbs liquid as it bakes, so the sauce should look slightly thin going in.
- Fold the tuna in gently. Leaving some chunks gives the bake better texture.
- Butter the crumbs. Tossing them with melted butter is what makes them brown and crisp.
Creamy Tuna Pasta Bake
Ingredients
Method
- Preheat the oven to 375°F. Grease an 8×8-inch or 2-quart baking dish.
- Cook the pasta in salted boiling water for 1–2 minutes less than the package directions. Drain.
- Melt 2 tablespoons of the butter in a large saucepan over medium heat. Whisk in the flour and cook for 1 minute. Slowly whisk in the milk and simmer for 3–4 minutes, until slightly thickened.
- Remove from the heat. Stir in the salt, pepper and 1 cup of the cheese until melted.
- Fold in the pasta, tuna and peas. Spread in the baking dish and top with the remaining cheese.
- Melt the remaining tablespoon of butter and toss it with the breadcrumbs. Sprinkle over the top.
- Bake for 20–25 minutes, until bubbly and golden.
Notes
- Add corn or small broccoli florets with the peas.
- Whole wheat pasta works well here.
- Crushed crackers can replace the breadcrumbs.

Tuna Pasta Bake Questions
Can I freeze it?
It can be frozen for up to 2 months, but the pasta softens and the sauce may separate slightly. It’s at its best fresh.
Can I skip the oven?
Yes. Cook the pasta fully, stir everything together on the stove until hot and serve it as a creamy skillet pasta.
How do I keep it from tasting fishy?
Drain the tuna well and add a squeeze of lemon juice or a teaspoon of Dijon mustard to the sauce.
