How To Store / Freeze This Casserole
Allow the spaghetti casserole to cool completely before storing. This helps prevent condensation, which can make the dish soggy.
For short-term storage, transfer the casserole to an airtight container. Store in the refrigerator for up to 3-4 days.
If you plan to freeze the casserole, portion it into individual servings. This makes reheating easier and reduces waste.
Wrap each portion tightly with plastic wrap or aluminum foil. Then, place the wrapped portions in a freezer-safe bag or container. Label with the date to keep track of freshness.
For best results, consume frozen portions within 2-3 months. This ensures the flavors and textures remain optimal.
When ready to reheat, thaw the casserole in the refrigerator overnight. This gradual thawing helps maintain the dish's integrity.
Reheat in the oven at 350°F (175°C) for about 20-25 minutes, or until heated through. Cover with foil to prevent the cheese from over-browning.
Alternatively, you can reheat individual portions in the microwave. Place the portion on a microwave-safe plate, cover with a microwave-safe lid or wrap, and heat on medium power for 2-3 minutes, or until hot.
For an extra touch, sprinkle some fresh herbs like basil or parsley on top before serving to revive the flavors.
