Tuna noodle casserole is one of those classic Midwestern comfort dishes that feels like a warm hug in a baking dish. It really took off in American home kitchens in the 1950s, when canned tuna and condensed soups became pantry staples and families were looking for economical, filling meals. At its best, this casserole is creamy, savory, and just a little bit nostalgic—a perfect make-ahead option for busy weeknights or casual gatherings. Using egg noodles gives it a tender, slightly rich base that stands up nicely to the sauce and tuna. This version keeps things simple and true to the original spirit, with just enough technique to ensure you get a bubbly, golden-topped casserole every time.
This tuna noodle casserole pairs well with bright, fresh sides to balance its richness. A simple green salad with a tangy vinaigrette (think mixed greens, thinly sliced red onion, and a lemony dressing) cuts through the creaminess nicely. Steamed or roasted vegetables—such as green beans, broccoli, or carrots—also make a good match and keep the meal feeling complete. If you’d like a little extra comfort on the table, warm dinner rolls or a crusty baguette are perfect for scooping up any leftover sauce. For a light finish, serve fresh fruit or a citrusy dessert to keep the meal from feeling too heavy.
Classic Tuna Noodle Casserole with Egg Noodles
Servings: 6 servings
Ingredients
8 oz (about 4 cups) wide egg noodles
2 (5 oz) cans tuna in water, drained and flaked
1 (10.5 oz) can condensed cream of mushroom soup
1 cup whole milk (or 2% milk)
1 cup frozen peas, thawed (or run under cool water to thaw quickly)
1/2 cup finely chopped celery (about 1 rib)
1/4 cup finely chopped onion
1 cup shredded cheddar cheese, divided
1/2 cup sour cream (optional but recommended for extra creaminess)
1/2 teaspoon kosher salt, plus more for pasta water
1/2 teaspoon freshly ground black pepper
1/2 teaspoon garlic powder
1/2 teaspoon dried thyme or dried parsley
1 cup crushed butter crackers or plain breadcrumbs
2 tablespoons unsalted butter, melted
Nonstick cooking spray or a little butter for greasing the baking dish
Directions
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with cooking spray or a thin layer of butter.
Bring a large pot of well-salted water to a boil. Add the egg noodles and cook until just shy of al dente, 1–2 minutes less than the package directions. The noodles will continue to cook in the oven, so keeping them slightly underdone helps prevent a mushy casserole. Drain and set aside.
While the noodles cook, prepare the sauce. In a large mixing bowl, whisk together the condensed cream of mushroom soup and milk until smooth. Stir in the sour cream (if using), 1/2 cup of the shredded cheddar cheese, salt, pepper, garlic powder, and dried thyme or parsley.
Fold the drained tuna, peas, chopped celery, and chopped onion into the sauce mixture, breaking up any large pieces of tuna with a fork. You’re aiming for an evenly distributed mixture so each bite has a bit of everything.
Add the drained egg noodles to the bowl and gently toss to coat them thoroughly in the sauce. Be careful not to overmix, as egg noodles are more delicate than some other pastas.
Transfer the mixture to the prepared baking dish, spreading it out into an even layer. Sprinkle the remaining 1/2 cup shredded cheddar cheese evenly over the top.
In a small bowl, combine the crushed butter crackers or breadcrumbs with the melted butter, stirring until the crumbs are evenly moistened. Scatter this mixture over the top of the casserole to create a crisp, golden crust.
Bake, uncovered, for 25–30 minutes, or until the casserole is bubbling around the edges and the topping is lightly browned. If the top is browning too quickly, you can loosely tent the dish with foil for the last 5–10 minutes.
Remove the casserole from the oven and let it rest for about 5–10 minutes before serving. This short resting time allows the sauce to thicken slightly and makes it easier to cut and serve neat portions.
Variations & Tips
This classic tuna noodle casserole is very adaptable to what you have in your pantry. For a slightly more modern flavor, you can swap the cream of mushroom soup for cream of celery or even a homemade white sauce (a simple roux with milk and a bit of stock) and add sautéed mushrooms. If you prefer a lighter dish, use low-sodium soup, reduced-fat milk, and skip the sour cream, adding a squeeze of lemon juice at the end to brighten the flavors. For extra vegetables, fold in sautéed mushrooms, bell peppers, or spinach along with the peas. The topping is another place to play: crushed potato chips, panko breadcrumbs, or even French-fried onions each add a different kind of crunch and nostalgia. If you’re cooking for someone who isn’t fond of tuna, the same base works well with canned salmon or shredded rotisserie chicken. Finally, for make-ahead convenience, assemble the casserole up to the point of baking, cover tightly, and refrigerate for up to 24 hours; when baking from cold, add an extra 5–10 minutes to the oven time and cover loosely with foil if the top browns too quickly.
