How To Store / Freeze This Casserole
Allow the egg and sausage casserole to cool completely at room temperature before storing. This helps prevent condensation, which can make the dish soggy.
For short-term storage, transfer the casserole to an airtight container or cover the baking dish tightly with plastic wrap or aluminum foil. Store in the refrigerator for up to 3-4 days.
If you plan to freeze the casserole, cut it into individual portions. This makes reheating easier and more convenient.
Wrap each portion tightly in plastic wrap, then place them in a resealable freezer bag or an airtight container. Label with the date to keep track of freshness.
For optimal quality, consume frozen portions within 2-3 months. While they may remain safe to eat beyond this period, the texture and flavor might degrade.
To reheat refrigerated portions, preheat your oven to 350°F (175°C). Place the casserole in an oven-safe dish and cover with aluminum foil. Heat for about 20-25 minutes or until warmed through.
For frozen portions, thaw them overnight in the refrigerator before reheating. If you're in a hurry, you can reheat directly from frozen by adding an extra 10-15 minutes to the baking time.
Alternatively, microwave reheating is an option. Place a portion on a microwave-safe plate, cover with a microwave-safe lid or another plate, and heat on medium power for 2-3 minutes. Check and stir halfway through to ensure even heating.
To maintain the best texture, avoid reheating the casserole multiple times. Reheat only the amount you plan to consume immediately.
Pair your reheated casserole with a fresh side salad or some steamed vegetables to add a burst of freshness and balance to your meal.
