How to Store or 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.
Once cooled, cut the casserole into individual portions. This makes it easier to reheat only what you need, reducing waste and maintaining freshness.
For short-term storage, place the portions in an airtight container. You can also use resealable plastic bags, ensuring you remove as much air as possible to keep the casserole fresh.
Store the container or bags in the refrigerator. The casserole will stay fresh for up to 3-4 days.
For longer storage, wrap each portion tightly in plastic wrap. Then, place the wrapped portions in a resealable freezer bag or an airtight container. Label the container with the date to keep track of its freshness.
Freeze the portions for up to 2-3 months. The egg and sausage casserole maintains its flavor and texture well when frozen properly.
When ready to enjoy, thaw the frozen portions in the refrigerator overnight. This gradual thawing helps maintain the dish's texture and flavor.
Reheat the thawed casserole in the microwave or oven. For the microwave, place the portion on a microwave-safe plate and cover it with a microwave-safe lid or another plate to retain moisture. Heat on medium power for 2-3 minutes, checking and stirring halfway through.
To reheat in the oven, preheat to 350°F (175°C). Place the portion in an oven-safe dish and cover with aluminum foil to prevent drying out. Heat 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 adds a fresh, melty layer of cheese that enhances the dish's flavor.
Enjoy your reheated egg and sausage casserole with a side of fresh fruit or a simple green salad for a balanced meal.
How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the leftover egg and sausage casserole in an oven-safe dish, cover with aluminum foil to prevent drying out, and bake for about 20-25 minutes or until heated through.
For a quicker option, use the microwave. Place a portion of the casserole on a microwave-safe plate, cover with a microwave-safe lid or another plate to retain moisture, and heat on medium power for 2-3 minutes. Check the temperature and continue heating in 30-second intervals until warmed through.
If you prefer a crispy top, use a toaster oven. Set it to 350°F (175°C), place the casserole on a baking sheet, and heat for 15-20 minutes. This method will help maintain the texture of the cheese and sausage.
For stovetop reheating, cut the casserole into smaller pieces and place them in a non-stick skillet over medium-low heat. Cover the skillet with a lid and heat for about 5-7 minutes, flipping occasionally to ensure even warming.
If you have an air fryer, preheat it to 350°F (175°C). Place the casserole pieces in the basket, making sure they are not overlapping, and heat for 5-7 minutes. This method will give you a nice, crispy exterior while keeping the inside moist.
