The ultimate tuna noodle casserole is an easy, family-friendly comfort food made with wide egg noodles, flaky tuna, creamy mushroom soup, sweet peas, cheddar cheese, and a crisp buttery breadcrumb topping. This classic recipe serves 6 and takes approximately 40–45 minutes from start to finish, including 15–20 minutes of prep, 7–9 minutes for boiling the noodles, and 20–25 minutes in the oven.
Every bite combines tender noodles with a creamy, savory sauce, mild tuna, melty cheddar, and golden crumbs that crackle lightly as you serve it. It is an especially practical weeknight dinner because the ingredients are simple, the casserole needs no complicated sauce, and the frozen peas can go straight into the mixing bowl.

This tuna noodle casserole earns its place in the regular dinner rotation because it delivers a complete meal from a short list of pantry and freezer staples. The creamy mushroom soup creates a savory sauce without requiring a separate roux, while milk loosens it enough to coat every noodle.
The texture is what makes this version so satisfying. The noodles remain pleasantly tender, the peas add little pops of sweetness, the tuna brings hearty protein, and the cheddar melts into the sauce while the buttery crumbs provide a golden contrast.
It is also an excellent make-and-bake option for busy evenings. While the oven heats, you can boil the noodles and mix the filling, making the casserole practical for a weeknight when you want something warm without a long list of steps.

Ingredients You’ll Need
The ingredient list is intentionally classic. Use wide egg noodles for their tender bite and broad shape, which gives the creamy sauce plenty of surface area to cling to.
- Wide egg noodles: You need 12 ounces, cooked just shy of tender.
- Tuna: Two 5-ounce cans should be drained thoroughly and flaked before mixing.
- Cream of mushroom soup and milk: Together, they form the quick, creamy casserole sauce.
- Frozen peas: One cup adds color and a mild sweetness; there is no need to thaw them first.
- Cheddar cheese: One cup is divided between the filling and the topping.
- Breadcrumbs or panko: Either works for the crisp finish. Panko tends to create a slightly airier crunch.
- Butter, salt, and pepper: Melted butter coats the crumbs, while the seasonings round out the savory flavor.
For the pasta water, use enough salt to season the noodles as they cook. Since the soup, tuna, and cheese may already contain salt, taste carefully before adding more than the specified 1/2 teaspoon to the sauce mixture.
How to Make It Step-by-Step
Step 1: Heat the oven to 375°F or 400°F and grease a 9-by-13-inch baking dish. Coating the dish helps with serving later and keeps the creamy noodles from sticking firmly to the sides.
Step 2: Bring a large pot of salted water to a boil and cook the egg noodles for 7–9 minutes, or 1–2 minutes less than the package directions. They should be just shy of tender because they will continue cooking while the casserole bakes.
Step 3: Drain the noodles very well. A thorough drain matters because extra water can make the sauce loose, and the finished casserole should be creamy enough to coat the noodles rather than watery at the bottom of the dish.
Step 4: In a large mixing bowl, combine the condensed cream of mushroom soup, milk, 1/2 teaspoon salt, and 1/4 teaspoon black pepper. Stir until the mixture looks smooth and evenly seasoned.
Step 5: Add the drained, flaked tuna, frozen peas, cooked noodles, and 3/4 cup of the cheddar. Fold gently until everything is coated, taking care not to crush the noodles or turn the tuna into a paste.
Step 6: Transfer the mixture to the greased baking dish and spread it into an even layer. An even surface helps the casserole heat at the same rate and gives the topping a consistent golden finish.
Step 7: Mix the dry breadcrumbs or panko with the 2 tablespoons of melted butter. Sprinkle the buttery crumbs over the noodles, then scatter the remaining 1/4 cup cheddar across the top.
Step 8: Bake the casserole uncovered for 20–25 minutes. Look for bubbling around the edges and a browned topping, then remove it from the oven and let it rest for 5 minutes before spooning it onto plates.
Pro Tips for the Best Casserole
The most important technique is to undercook the noodles slightly. Fully cooked noodles can become soft or mushy after spending another 20–25 minutes in the oven, whereas noodles removed 1–2 minutes early finish cooking in the creamy sauce.
Drain the tuna thoroughly and flake it with a fork before adding it to the bowl. Too much liquid from the cans can dilute the sauce, while large compact pieces of tuna can leave some servings less evenly distributed.
Keep the casserole uncovered during baking so moisture can escape and the topping can brown. Begin checking around the 20-minute mark, since oven temperatures vary and overbaking can dry the edges.
For a scratch-style variation, replace the condensed soup with a sauce made from butter, flour, milk, and chicken broth. You can also add sautéed onion, garlic, and fresh mushrooms, or mix Parmesan into the breadcrumbs for a more savory topping; sour cream or mayonnaise can add richness, but neither is essential to the classic recipe.
When planning a full comfort-food menu, serve this casserole with a crisp green salad or steamed vegetables. On a chilly night, a bowl of spicy chicken noodle soup may inspire another cozy dinner idea for the week.
Serving Suggestions
Letting the casserole rest for 5 minutes makes it easier to scoop and gives the creamy filling a moment to settle. Serve generous portions while the topping is still crisp and the cheese is warm.
A simple green salad, sliced cucumbers, roasted vegetables, or lightly dressed cabbage can balance the richness. If you are serving a larger comfort-food spread, easy minestrone soup offers a vegetable-filled option for another meal or a light first course.
For extra color at the table, add a small sprinkle of chopped parsley after baking. The classic recipe is flavorful as written, so any garnish should be used lightly rather than covering the crunchy breadcrumb layer.
Storage & Reheating
Cool leftover casserole promptly, cover it well, and refrigerate it. It is best enjoyed within a few days, reheated until hot throughout.
For individual portions, use the microwave in short intervals, stirring or checking the center between intervals when possible. For a larger amount, place it in an oven-safe dish and warm it in the oven until heated through; covering it at first can help protect the noodles from drying, while uncovering near the end can bring back some topping crispness.
If you are organizing several make-ahead meals, pair this recipe with other hearty favorites such as an easy stovetop turkey chili. Save a simple sweet treat like KitKat fudge for dessert when you want the meal to finish with a playful chocolate bite.
Common Questions
Can I use another pasta shape? Wide egg noodles are the standard choice, but another medium pasta can work if it is cooked just shy of tender. Keep the total amount at 12 ounces so the sauce remains balanced.
Should I thaw the peas? No. The frozen peas can be stirred directly into the bowl, where they will warm as the casserole bakes.
How do I know it is done? The casserole is ready when it is hot, bubbling around the edges, and topped with golden crumbs. Rest it for 5 minutes before serving for the best texture.
