Safely store your delicious homemade tuna casserole to enjoy its creamy texture and savory flavors for days to come. Proper refrigeration is key to preserving the freshness of this comforting dish, ensuring it remains a delightful meal option.

Storage Time

3–4 days in the refrigerator, up to 2–3 months in the freezer for best quality.

Temperature

Keep refrigerated at or below 4°C (40°F).

Freezing

Yes, homemade tuna casserole freezes beautifully! Allow the casserole to cool completely before portioning it into airtight containers or heavy-duty freezer bags. For best results, avoid freezing if it contains a very creamy sauce, as it might separate slightly upon thawing. To thaw, transfer the frozen casserole to the refrigerator overnight and reheat gently in the oven or microwave until heated through. Do not refreeze once thawed.

Signs of Spoilage

• A sour or off smell, distinct from its usual savory aroma.
• A slimy or mushy texture, especially in the noodles or tuna.
• Visible mold growth, which can appear as fuzzy spots of various colors.
