How to Store / Freeze Your Dish
Allow the egg casserole to cool completely after baking. This helps prevent condensation, which can make the dish soggy.
For short-term storage, cover the baking dish tightly with plastic wrap or transfer the casserole to an airtight container. Store it in the refrigerator for up to 3-4 days.
To freeze, cut the cooled casserole into individual portions. Wrap each portion tightly in plastic wrap or aluminum foil. Place the wrapped portions in a freezer-safe bag or container. Label with the date and contents.
When ready to reheat, thaw the frozen portions in the refrigerator overnight. This ensures even reheating and maintains the texture of the egg casserole.
Reheat in the microwave by placing a portion on a microwave-safe plate. Cover with a damp paper towel to retain moisture and heat on medium power for 1-2 minutes, or until heated through.
Alternatively, reheat in the oven by placing the thawed portions in a baking dish. Cover with aluminum foil and bake at 350°F (175°C) for 15-20 minutes, or until warmed through.
For an extra touch, sprinkle a bit of shredded cheddar cheese on top before reheating in the oven. This will give the casserole a fresh, melty finish.
Avoid refreezing previously frozen portions, as this can affect the texture and flavor of the egg casserole.
How to Reheat Leftovers
Oven Method: Preheat your oven to 350°F (175°C). Place the leftover egg casserole in an oven-safe dish. Cover it with aluminum foil to prevent it from drying out. Heat for about 20-25 minutes or until it is warmed through and the cheese is melty.
Microwave Method: Place a portion of the egg casserole on a microwave-safe plate. Cover it with a microwave-safe lid or a damp paper towel to retain moisture. Heat on medium power for 1-2 minutes, checking halfway through to ensure it heats evenly. If needed, continue heating in 30-second intervals until hot.
Stovetop Method: Heat a non-stick skillet over medium-low heat. Add a small amount of butter or olive oil to the pan. Place the egg casserole in the skillet and cover with a lid. Heat for about 5-7 minutes, flipping occasionally to ensure even warming.
Air Fryer Method: Preheat your air fryer to 300°F (150°C). Place the egg casserole in the air fryer basket. Heat for about 5-7 minutes, checking halfway through to ensure it heats evenly. This method will give the casserole a slightly crispy texture on the outside.
Toaster Oven Method: Preheat your toaster oven to 350°F (175°C). Place the egg casserole on a toaster oven-safe tray. Cover with aluminum foil and heat for about 15-20 minutes or until warmed through. Remove the foil for the last 5 minutes if you prefer a crispy top.
