How This Recipe Comes Together
First, cook the pasta just until al dente so it does not turn mushy in the oven. Then stir together the creamy sauce, combine it with tuna, peas, cheese, and pasta, and spread everything into a casserole dish. Add cheese and an optional crunchy topping, then bake until hot, bubbly, and lightly golden.

Tips Before You Start
Use short pasta shapes that hold sauce well, such as shells, rotini, penne, macaroni, or bowties.
Cook the pasta just until al dente. Soft pasta can turn mushy after baking.
Drain the tuna well so the casserole does not become watery.
Frozen peas can go in straight from the freezer. They will heat through while the casserole bakes.
For a creamier bake, stir in an extra splash of milk before baking.
For a crispier top, use crushed buttery crackers, breadcrumbs, or crushed plain potato chips.
Ingredient Swaps
No cream of mushroom soup?
Use cream of chicken, cream of celery, or a simple homemade white sauce.
No peas?
Use frozen corn, mixed vegetables, chopped broccoli, or spinach.
No cheddar?
Use mozzarella, Monterey Jack, Colby Jack, or a mild shredded cheese blend.
No sour cream?
Use plain Greek yogurt, extra milk, or leave it out for a simpler sauce.
Want more flavor?
Add a spoonful of Dijon mustard, a pinch of paprika, or a small squeeze of lemon juice after baking.
Storage
Let leftovers cool, then store them in an airtight container in the refrigerator for up to 3 to 4 days.
Do not leave the casserole sitting out at room temperature for more than 2 hours.
Reheating
Reheat individual portions in the microwave until steaming hot.
To reheat in the oven, cover the baking dish with foil and warm at 350°F until heated through. Add a splash of milk before reheating if the pasta looks dry.
Food Safety Note
Because this recipe includes fish, dairy, and leftovers, keep it refrigerated after serving. Leftovers and casseroles should be reheated to 165°F, according to FoodSafety.gov and USDA guidance. Baking and reheating times can vary by oven, dish size, pasta amount, and starting temperature, so do not rely on time alone. A food thermometer is the most reliable way to check when food safety matters.
