How to Store / Freeze This Dish
Allow the tuna casserole to cool completely after baking. This prevents condensation, which can make the dish soggy.
For storing in the refrigerator:
- Transfer the casserole to an airtight container or cover the baking dish tightly with plastic wrap or aluminum foil.
- Store in the refrigerator for up to 3-4 days.
- Reheat individual portions in the microwave or the entire dish in the oven at 350°F (175°C) until heated through.
For freezing:
- Once the tuna casserole has cooled, portion it into individual servings or keep it whole, depending on your preference.
- Wrap each portion tightly with plastic wrap and then with aluminum foil, or place them in airtight freezer-safe containers.
- Label each package with the date and contents to keep track of freshness.
- Freeze for up to 2-3 months for optimal flavor and texture.
Reheating from frozen:
- Thaw the tuna casserole in the refrigerator overnight for best results.
- Preheat your oven to 350°F (175°C).
- Remove any plastic wrap and cover the casserole with aluminum foil.
- Bake for 20-30 minutes or until heated through. If reheating individual portions, microwave on high for 2-3 minutes, checking and stirring halfway through.
Tips for maintaining texture and flavor:
- Avoid freezing the bread crumb topping. Instead, add fresh bread crumbs mixed with melted butter just before reheating in the oven to retain the crunchy texture.
- If the casserole seems dry after reheating, add a splash of milk or cream of mushroom soup to restore moisture.
- For added freshness, sprinkle some freshly grated cheddar cheese on top before reheating.
How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the leftover tuna 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.
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. Heat on medium power for 2-3 minutes, stirring halfway through to ensure even heating.
If you prefer a crispy top, use the broiler. First, reheat the casserole in the microwave for 2-3 minutes. Then, transfer it to an oven-safe dish and place it under the broiler for 2-3 minutes until the top is bubbly and golden brown.
For stovetop reheating, place the casserole in a non-stick skillet over medium heat. Add a splash of milk or broth to keep it moist. Stir occasionally and heat until warmed through, about 5-7 minutes.
If you have an air fryer, preheat it to 350°F (175°C). Place the casserole in an air fryer-safe dish and heat for 5-7 minutes, checking halfway through to ensure it doesn’t overcook.
