This tuna noodle casserole is a comforting and easy-to-make dish that's perfect for busy weeknights. Combining tender egg noodles, flaky tuna, and a creamy mushroom sauce, it's a family favorite that brings warmth to the dinner table.

Ingredients For Tuna Noodle Casserole Recipe
Egg noodles: These are the base of the casserole, providing a hearty texture and absorbing the flavors of the sauce.
Tuna: Canned tuna adds protein and a savory flavor to the dish.
Cream of mushroom soup: This soup creates a creamy, flavorful sauce that binds the casserole together.
Frozen peas: These add a pop of color and a sweet, fresh taste to the casserole.
Cheddar cheese: Shredded cheddar melts into the casserole, adding a rich, cheesy flavor.
Milk: This helps to thin out the soup, creating a smooth, creamy sauce.
Breadcrumbs: Optional, but they add a crunchy topping to the casserole.
Technique Tip for This Recipe
When preparing the egg noodles, make sure to cook them just until al dente. This ensures they maintain a slight firmness and won't become mushy during the baking process. Additionally, when mixing the tuna, cream of mushroom soup, peas, cheese, and milk, ensure the ingredients are evenly distributed to achieve a consistent flavor throughout the casserole. If using breadcrumbs for the topping, consider toasting them lightly in a pan with a bit of butter before adding them to the dish. This will give them a richer flavor and a satisfying crunch.

How to Store or Freeze This Casserole
Allow the tuna noodle casserole to cool completely before storing. This helps prevent condensation, which can make the dish soggy.
For short-term storage, transfer the casserole to an airtight container. Refrigerate for up to 3-4 days. When ready to eat, reheat in the oven at 350°F (175°C) until warmed through, about 15-20 minutes.
For freezing, portion the casserole into individual servings or keep it whole. Wrap each portion tightly in plastic wrap, then place in a freezer-safe container or heavy-duty freezer bag. Label with the date and contents.
To reheat from frozen, preheat your oven to 350°F (175°C). Remove the plastic wrap and cover the casserole with aluminum foil. Bake for 45-60 minutes, or until heated through. For a crispy topping, remove the foil during the last 10 minutes of baking.
If you prefer to use a microwave, thaw the casserole in the refrigerator overnight. Transfer to a microwave-safe dish and heat on medium power, stirring occasionally, until hot.
For added freshness, sprinkle some extra shredded cheddar cheese or breadcrumbs on top before reheating. This will help revive the texture and flavor.
Avoid freezing casseroles that contain high-water content vegetables like zucchini or tomatoes, as they can become mushy when thawed. Stick to ingredients like peas and mushrooms that hold up well in the freezer.
If you plan to freeze the casserole, consider undercooking the egg noodles slightly. They will finish cooking during the reheating process, preventing them from becoming overly soft.
Always use fresh ingredients when preparing a casserole for freezing. This ensures the best possible taste and texture when you’re ready to enjoy it later.
How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the leftover tuna noodle casserole in an oven-safe dish. Cover it with aluminum foil to prevent it from drying out. Bake for about 20-25 minutes, or until heated through and bubbly.
For a quicker method, use the microwave. Transfer a portion of the casserole to a microwave-safe dish. Cover it with a microwave-safe lid or plastic wrap, leaving a small vent for steam to escape. Heat on medium power for 2-3 minutes, stirring halfway through to ensure even heating. Continue heating in 1-minute intervals if needed.
If you prefer a stovetop method, place the leftover casserole in a non-stick skillet. Add a splash of milk or broth to keep it moist. Cover and heat over medium-low heat, stirring occasionally, until warmed through.
For an air fryer, preheat it to 350°F (175°C). Place the casserole in an air fryer-safe dish. Heat for about 10 minutes, checking halfway through to ensure it doesn't dry out. This method can help retain a crispy topping if you used breadcrumbs.
If you have a toaster oven, preheat it to 350°F (175°C). Place the leftover casserole in a toaster oven-safe dish. Cover with foil and heat for 15-20 minutes, or until thoroughly warmed. This method is great for smaller portions.
