How to Store or Freeze This Dish
Allow the tuna casserole to cool completely before storing. This helps prevent condensation, which can make the breadcrumbs topping soggy.
For short-term storage, transfer the casserole to an airtight container. Refrigerate for up to 3-4 days. When ready to enjoy, reheat in the oven at 350°F (175°C) until warmed through, or microwave individual portions.
To freeze, first wrap the entire baking dish tightly with plastic wrap, ensuring it is well-sealed to prevent freezer burn. Then, cover with a layer of aluminum foil for extra protection. Alternatively, you can portion the casserole into individual servings and store in freezer-safe containers.
Label the container with the date and contents. Frozen tuna casserole can be stored for up to 2-3 months.
When ready to eat, thaw the casserole in the refrigerator overnight. Reheat in a preheated oven at 350°F (175°C) for about 20-30 minutes, or until the casserole is heated through and the breadcrumbs topping is crispy.
For a quicker option, you can reheat directly from frozen. Cover the casserole with foil and bake at 350°F (175°C) for 45-50 minutes. Remove the foil for the last 10 minutes to allow the breadcrumbs to crisp up.
If the casserole seems dry upon reheating, add a splash of milk or cream of mushroom soup to restore its creamy texture.
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, and bake for about 20-25 minutes or until heated through.
For a quicker option, 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), and heat on medium power for 2-3 minutes. Stir halfway through to ensure even heating.
If you prefer a crispy top, reheat in a skillet. Place a portion of the casserole in a non-stick skillet over medium heat. Cover with a lid and cook for about 5-7 minutes, stirring occasionally, until heated through and the bottom is slightly crispy.
For an air fryer, preheat it to 350°F (175°C). Place the tuna casserole in an air fryer-safe dish, cover with foil, and heat for about 10-15 minutes, checking halfway through to ensure it’s warming evenly. Remove the foil for the last few minutes if you want a crispy top.
To reheat on the stovetop, place the casserole in a saucepan or skillet with a splash of milk or cream of mushroom soup to keep it moist. Cover and heat over low to medium heat, stirring occasionally, until warmed through.
