This tuna casserole is a comforting and easy-to-make dish that brings together simple ingredients for a delicious meal. Perfect for busy weeknights or a cozy family dinner, this recipe combines egg noodles, tuna, and peas in a creamy mushroom soup base, topped with cheddar cheese and breadcrumbs for a satisfying crunch.
While most of the ingredients in this recipe are pantry staples, you might need to pick up a can of cream of mushroom soup and a bag of frozen peas if they are not already in your kitchen. Additionally, make sure you have egg noodles and breadcrumbs on hand, as these are essential for the texture and structure of the casserole.

Ingredients for Tuna Casserole Recipe
Egg noodles: These are the base of the casserole, providing a hearty and filling component.
Tuna: Adds protein and a savory flavor to the dish.
Frozen peas: Brings a pop of color and a slight sweetness to balance the savory elements.
Cream of mushroom soup: Acts as the creamy binder that holds the casserole together.
Shredded cheddar cheese: Melts into the casserole, adding richness and a cheesy flavor.
Milk: Helps to thin out the soup and create a smooth sauce.
Breadcrumbs: Sprinkled on top for a crunchy, golden-brown crust.
Technique Tip for This Recipe
When preparing the egg noodles, ensure they are cooked al dente. This means they should be firm to the bite and not overly soft. Overcooking the noodles can result in a mushy texture once the casserole is baked. To achieve this, follow the package instructions closely and taste-test a noodle a minute or two before the suggested cooking time is up. This will help maintain the structural integrity of the casserole and provide a more enjoyable eating experience.

How to Store / Freeze This Casserole
Allow the tuna casserole to cool completely at room temperature before storing. This prevents condensation from forming inside the storage container, which can make the dish soggy.
Transfer the cooled casserole to an airtight container. If you don't have one large enough, you can use multiple smaller containers or cover the baking dish tightly with plastic wrap or aluminum foil.
For short-term storage, place the container in the refrigerator. The tuna casserole will stay fresh for up to 3-4 days.
For longer storage, consider freezing the casserole. Wrap the container tightly with plastic wrap and then a layer of aluminum foil to prevent freezer burn. Label the container with the date for easy reference.
When ready to reheat, if frozen, transfer the casserole to the refrigerator to thaw overnight. This ensures even reheating and maintains the texture of the dish.
To reheat, preheat your oven to 350°F (175°C). Remove any plastic wrap and cover the casserole with aluminum foil to prevent the top from burning. Heat for 20-25 minutes, or until the casserole is warmed through.
For a crispier topping, remove the foil during the last 5 minutes of reheating. This will help the breadcrumbs regain their crunch.
If reheating individual portions, you can use a microwave. Place a portion on a microwave-safe plate, cover with a microwave-safe lid or another plate, and heat on medium power for 2-3 minutes, or until hot. Stir halfway through to ensure even heating.
Enjoy your reheated tuna casserole as if it were freshly baked!
