- Butter: Adds richness and helps soften the onions for a flavorful base.
- Small onion, chopped: Brings a mild sweetness and depth when cooked down.
- Cans of cream of mushroom soup (undiluted): Creates the creamy, savory sauce that ties everything together.
- Milk: Lightens the soup sauce and ensures a velvety texture.
- Frozen peas (thawed and drained): Adds a fresh pop of color and a subtle sweetness.
- Cans of tuna (drained): The protein star of the dish, offering a mild, tender bite.

How to Make Tuna Noodle Casserole Recipe
Step 1: Preheat and Prepare
Begin by preheating your oven to 400°F to get it ready for baking. Spray a 3-quart casserole dish with cooking spray to prevent sticking and make cleanup easier. Setting this up early ensures a smooth workflow as we prepare the ingredients.
Step 2: Sauté the Onions
In a small skillet, melt the butter over medium-high heat. Add the chopped onion and cook it until it turns soft and translucent. This step is essential because it unlocks the onion’s natural sweetness and creates a fragrant base that enhances the whole casserole.
Step 3: Combine the Ingredients
While the onions cook, grab a large bowl and combine the cream of mushroom soup, milk, thawed peas, drained tuna, and cooked egg noodles. Once your onions are ready, add them to the mixture and stir everything together until evenly mixed. This harmony of ingredients forms the hearty filling of your casserole.
Step 4: Assemble and Add Cheese
Transfer the mixed ingredients into the prepared casserole dish, spreading it out evenly. Next, generously sprinkle the shredded cheddar cheese over the top. The cheese is the crowning glory that melts into a bubbly, golden crust that everyone loves.
Step 5: Bake Until Bubbly
Place the casserole in your preheated oven and bake it for 20 to 25 minutes. You want the mixture to be piping hot throughout and the cheese melted and slightly golden. Once baked, the kitchen will be filled with that irresistible aroma announcing a meal ready to devour.
How to Serve Tuna Noodle Casserole Recipe
Garnishes
While the Tuna Noodle Casserole Recipe shines on its own, a little garnish can elevate the presentation. Try sprinkling freshly chopped parsley or chives on top to add a burst of color and a fresh, herbaceous note that balances the creaminess.
Side Dishes
This casserole pairs wonderfully with simple sides like a crisp green salad dressed with lemon vinaigrette or steamed broccoli. These lighter accompaniments provide contrast to the richness of the casserole and round out your meal with extra texture and freshness.
Creative Ways to Present
For a fun twist, serve the Tuna Noodle Casserole Recipe in individual ramekins for a charming, personal touch. You can also add a crunchy topping with breadcrumbs mixed with a little melted butter sprinkled over the cheese before baking, adding a delightful textural surprise.
Make Ahead and Storage
Storing Leftovers
Any leftover Tuna Noodle Casserole Recipe should be transferred to an airtight container and refrigerated promptly. It will keep well for up to 3 days, making it a convenient and tasty option for quick meals later in the week.
Freezing
This casserole freezes beautifully. To freeze, prepare the recipe up to the baking step, cover the casserole tightly with foil or plastic wrap, and freeze for up to 2 months. When you’re ready, bake it straight from the freezer, adding extra baking time until heated through and bubbly.
Reheating
Reheat leftovers in the oven at 350°F for about 15-20 minutes or until warmed through, which helps preserve the casserole’s texture and cheesy top. Microwaving is also fine for portions, but it may soften the crispy cheese layer.
FAQs
Can I use fresh mushrooms instead of cream of mushroom soup?
Absolutely! For a fresher, more homemade flavor, sauté finely chopped fresh mushrooms with the onions. You’ll then want to add a bit of extra milk or cream to keep the casserole moist since fresh mushrooms won’t provide the same creaminess as the soup.
Is there a way to make this recipe healthier?
Yes, you can swap the cream of mushroom soup with a low-fat or homemade version, use whole wheat noodles for added fiber, and reduce the cheese quantity or opt for a sharper cheese so you can use less but still get plenty of flavor.
Can this recipe be made dairy-free?
Certainly! Use dairy-free cream of mushroom soup alternatives, substitute milk with unsweetened plant-based milk, and choose dairy-free cheese for the topping. This way you keep the classic taste without the dairy.
How can I add more vegetables to Tuna Noodle Casserole Recipe?
Adding vegetables like diced carrots, chopped celery, or even mushrooms alongside the peas works beautifully. Just sauté them lightly with the onions to soften before mixing into the casserole.
What type of tuna works best for this casserole?
Canned tuna packed in water is ideal for a lighter taste, but if you prefer a richer flavor, tuna packed in oil adds extra depth. Just be sure to drain it well to avoid sogginess in the casserole.
