While most of the ingredients for this recipe are common pantry staples, you may need to pick up a few items at the supermarket. Make sure you have egg noodles, canned tuna, frozen peas, cream of mushroom soup, milk, shredded cheddar cheese, breadcrumbs, and butter. These ingredients are essential for creating the creamy and flavorful base of the casserole.

Ingredients For Tuna Noodle Casserole
Egg noodles: These are the base of the casserole, providing a hearty and filling texture.
Tuna: Canned tuna adds protein and a savory flavor to the dish.
Frozen peas: These add a pop of color and a touch of sweetness.
Cream of mushroom soup: This creates the creamy sauce that binds all the ingredients together.
Milk: Helps to thin out the soup and create a smooth sauce.
Shredded cheddar cheese: Adds a rich, cheesy flavor to the casserole.
Breadcrumbs: These create a crispy, golden topping.
Butter: Used to mix with the breadcrumbs for the topping, adding richness and flavor.
Technique Tip for This Recipe
When preparing the breadcrumbs topping, ensure that the butter is fully melted and evenly mixed with the breadcrumbs. This will create a uniform, golden-brown crust that adds a delightful crunch to the casserole. Additionally, for an extra layer of flavor, consider toasting the breadcrumbs lightly in a pan before mixing them with the butter. This step enhances the nutty flavor and provides a more complex texture to the dish.

How to Store or Freeze This Casserole
Allow the tuna noodle casserole to cool completely before storing. This prevents 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.
If you plan to freeze the casserole, portion it into individual servings. This makes reheating easier and reduces waste.
Wrap each portion tightly with plastic wrap, then place them in a freezer-safe bag or container. Label with the date to keep track of freshness.
To reheat from the refrigerator, preheat your oven to 350°F (175°C). Place the casserole in an oven-safe dish and cover with foil. Heat for 20-25 minutes or until warmed through.
For reheating from frozen, allow the casserole to thaw in the refrigerator overnight. Then follow the same reheating instructions as above.
If you prefer to use the microwave, place the portion in a microwave-safe dish. Cover loosely and heat on medium power in 1-minute intervals, stirring occasionally, until hot.
To maintain the crispy topping, consider reheating the casserole in the oven rather than the microwave. This helps keep the breadcrumbs crunchy.
Avoid refreezing the casserole once it has been thawed, as this can affect the texture and flavor of the egg noodles and other ingredients.
For added freshness, you can sprinkle a bit of extra shredded cheddar cheese on top before reheating. This gives the dish a freshly baked feel.
