How to Store or Freeze This Casserole
Allow the tuna casserole to cool to room temperature before storing or freezing. This prevents condensation and sogginess.
For short-term storage, transfer the casserole to an airtight container. Refrigerate for up to 3-4 days. Reheat in the oven at 350°F (175°C) until warmed through, or microwave in individual portions.
To freeze, portion the casserole into individual servings or keep it whole. Wrap each portion tightly with plastic wrap, then aluminum foil, or place in a freezer-safe container. This double layer prevents freezer burn.
Label the containers with the date and contents. Frozen tuna casserole can be stored for up to 2-3 months.
When ready to enjoy, thaw the casserole in the refrigerator overnight. Reheat in the oven at 350°F (175°C) for 20-30 minutes, or until heated through. If reheating from frozen, cover with foil and bake for 45-60 minutes, removing the foil for the last 10 minutes to crisp the top.
For a crispy topping, add a fresh layer of breadcrumbs and shredded cheddar cheese before reheating. This ensures a delightful texture even after freezing.
Avoid freezing casserole with high water content vegetables like zucchini or tomatoes, as they can become mushy upon reheating. Stick to ingredients like peas and tuna that hold up well in the freezer.
