What is the typical shelf life of tuna casserole in the refrigerator?

The shelf life of tuna casserole in the refrigerator typically ranges from 3 to 5 days. This is because the casserole contains perishable ingredients such as tuna, dairy products, and eggs, which can spoil quickly if not stored properly. It’s essential to store the casserole in a covered container and keep it refrigerated at a temperature of 40°F (4°C) or below to prevent bacterial growth.

If you notice any signs of spoilage, such as an off smell, slimy texture, or mold growth, it’s best to err on the side of caution and discard the casserole. Even if the casserole looks and smells fine, it’s still possible for bacteria to be present, which can cause food poisoning. Therefore, it’s crucial to consume the casserole within the recommended timeframe and always check its condition before serving.

Can I freeze tuna casserole to extend its shelf life?

Yes, you can freeze tuna casserole to extend its shelf life. Freezing is an excellent way to preserve the casserole for a longer period. When frozen, the casserole can last for up to 3-4 months. It’s essential to freeze the casserole in an airtight container or freezer bag to prevent freezer burn and other flavors from affecting the casserole.
