Ingredients For Tuna Casserole
Egg noodles: A type of pasta made with eggs, giving them a rich flavor and tender texture.
Tuna: Canned tuna, a convenient and protein-rich ingredient.
Peas: Frozen peas add a pop of color and sweetness.
Cream of mushroom soup: A creamy soup that serves as the base for the casserole.
Cheddar cheese: Shredded cheese that melts into the casserole, adding a rich, cheesy flavor.
Milk: Helps to thin out the soup and create a creamy sauce.
Breadcrumbs: Optional topping that adds a crunchy texture to the casserole.
Technique Tip for This Recipe
To enhance the flavor of your tuna casserole, consider sautéing the frozen peas in a bit of butter and garlic before mixing them into the casserole mixture. This will add a subtle depth of flavor and make the peas more tender. Additionally, for a crispier topping, toast the breadcrumbs in a skillet with a little olive oil until golden brown before sprinkling them over the casserole.

How to Store or Freeze This Dish
Allow the tuna 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. Store it in the refrigerator 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 or aluminum foil. For added protection, place the wrapped portions in a resealable freezer bag or an airtight container.
Label the containers with the date and contents. This helps you keep track of how long the tuna casserole has been stored.
When ready to enjoy, thaw the casserole in the refrigerator overnight. This ensures even reheating and maintains the dish's texture.
Reheat the thawed casserole in a preheated oven at 350°F (175°C) for about 20-25 minutes, or until heated through. If reheating from frozen, it may take up to 45 minutes.
For a crispy topping, add fresh breadcrumbs or additional shredded cheddar cheese before reheating.
If using a microwave, reheat individual portions on medium power to avoid drying out the egg noodles and tuna. Cover with a microwave-safe lid or wrap to retain moisture.
Always check the internal temperature of the reheated casserole. It should reach at least 165°F (74°C) to ensure it is safe to eat.
How to Reheat Leftovers
Oven Method:
- Preheat your oven to 350°F (175°C).
- Place the leftover tuna casserole in an oven-safe dish. If it seems a bit dry, you can add a splash of milk or cream of mushroom soup to keep it moist.
- Cover the dish with aluminum foil to prevent the top from over-browning.
- Bake for about 20-25 minutes, or until the casserole is heated through and bubbly.
- Remove the foil for the last 5 minutes if you want to crisp up the breadcrumbs topping again.
Microwave Method:
- Place a portion of the tuna casserole in a microwave-safe dish.
- Cover the dish with a microwave-safe lid or plastic wrap, leaving a small corner open to vent steam.
- Microwave on medium power for 2-3 minutes, then stir.
- Continue microwaving in 1-minute intervals, stirring in between, until the casserole is heated through.
Stovetop Method:
- Transfer the leftover tuna casserole to a large skillet or saucepan.
- Add a splash of milk or cream of mushroom soup to help rehydrate the dish.
- Heat over medium-low, stirring occasionally, until the casserole is warmed through.

Air Fryer Method:
- Preheat your air fryer to 350°F (175°C).
- Place the leftover tuna casserole in an air fryer-safe dish.
- Heat for about 10-15 minutes, checking halfway through to ensure it’s not drying out. You can add a bit of milk if needed.
