This 5-ingredient oven baked tuna egg noodles recipe is the kind of practical pantry dinner that earns a regular spot in a busy weeknight rotation. By layering dry egg noodles with undrained chunk light tuna and a few shelf-stable basics, you get a creamy, savory casserole-style meal with very little prep and almost no stovetop work. It’s a smart shortcut meal that leans on classic American tuna-noodle comfort food, but simplifies the method into an easy dump-and-bake format.
Serve this dish with something fresh and crisp to balance its creamy, hearty character. A simple green salad with a sharp vinaigrette, steamed green beans, roasted broccoli, or peas all pair nicely, and a piece of buttered toast or warm dinner rolls works well for soaking up the sauce. If you want a brighter finish, a squeeze of lemon and a sprinkle of parsley at the table help lighten the flavors.
5-Ingredient Oven Baked Tuna Egg Noodles
Servings: 4 to 6
Ingredients
8 ounces dry uncooked egg noodles
2 cans (5 ounces each) chunk light tuna, undrained
1 can (10.5 ounces) condensed cream of mushroom soup
2 cups milk
1 cup shredded cheddar cheese
Directions
1. Preheat the oven to 375°F. Lightly grease an oven-safe sheet pan or a small rimmed baking tray with sides so the liquid stays contained while the noodles bake.
2. Spread the dry egg noodles evenly in the prepared pan. Spoon the undrained tuna over the noodles, then add the condensed cream of mushroom soup and pour the milk over everything.
3. Stir well so the soup and milk combine and coat the noodles. Make sure the noodles are mostly submerged in the liquid, then spread the mixture into an even layer.
4. Cover the pan tightly with foil and bake for 25 minutes. Remove the foil, stir the noodles to prevent sticking, and check that they are softening as they absorb the liquid.
5. Sprinkle the shredded cheddar cheese evenly over the top. Return the pan to the oven, uncovered, and bake for 10 to 15 minutes more, until the noodles are tender, the sauce is bubbly, and the cheese is melted and lightly golden. Let rest for 5 minutes before serving.
Variations & Tips
Add vegetables: Frozen peas are the most natural addition here and can be stirred in before baking without thawing. Diced cooked carrots or sautéed mushrooms also fit well if you want a more complete one-pan dinner.
Change the soup base: Cream of celery or cream of chicken can be used instead of cream of mushroom if that is what you have in the pantry. Each will change the flavor slightly, but the texture will remain similarly creamy.
Use a deeper dish if needed: If your sheet pan is very shallow, switch to a 9-by-13-inch baking dish so the liquid does not spill. The key is keeping the noodles surrounded by enough liquid to cook through properly in the oven.
Prevent dry noodles: Oven temperatures and noodle thickness can vary, so if the mixture looks dry before the noodles are tender, add a small splash of milk, cover again, and continue baking for a few more minutes. Resting the casserole after baking also helps the sauce thicken and settle.
Finish with extra flavor: A little black pepper, garlic powder, dried dill, or a squeeze of lemon can sharpen the flavor without changing the simple pantry nature of the recipe. If you like a crisper top, place the pan under the broiler for 1 to 2 minutes at the end, watching closely.
