How To Store or Freeze This Casserole
- Allow the casserole to cool completely before storing. This helps to prevent condensation, which can make the dish soggy.
- For short-term storage, cover the baking dish tightly with plastic wrap or aluminum foil and place it in the refrigerator. It will stay fresh for up to 3-4 days.
- If you prefer to store individual portions, cut the casserole into squares and place them in airtight containers. This makes it easy to grab a quick breakfast or snack.
- To freeze the casserole, first ensure it is fully cooled. Then, wrap the entire dish or individual portions tightly in plastic wrap, followed by a layer of aluminum foil. This double wrapping helps to prevent freezer burn.
- Label the wrapped casserole with the date and contents before placing it in the freezer. It can be stored for up to 2-3 months.
- When ready to enjoy, thaw the casserole in the refrigerator overnight. This gradual thawing helps maintain the texture and flavor.
- Reheat the casserole in the oven at 350°F (175°C) for about 20-25 minutes, or until heated through. If reheating individual portions, you can use a microwave, heating on high for 1-2 minutes or until warm.
- For added freshness, sprinkle a bit of extra shredded cheddar cheese on top before reheating. This will give it a freshly baked feel.
- If the casserole seems a bit dry after reheating, consider adding a splash of milk or a dollop of sour cream to moisten it up.
- Always check the internal temperature of the reheated casserole to ensure it reaches at least 165°F (74°C) for safe consumption.
How To Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the leftover Wake Up 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, and heat on medium power for 2-3 minutes. Check and stir halfway through to ensure even heating.
If you prefer a crispy top, use a toaster oven. Preheat the toaster oven to 350°F (175°C), place the casserole on a toaster oven tray, and heat for 15-20 minutes. Keep an eye on it to avoid burning.
For stovetop reheating, place a non-stick skillet over medium heat. Add a small amount of olive oil or butter to the pan, then add the casserole. Cover with a lid and heat for 5-7 minutes, stirring occasionally to ensure even heating.
If you have an air fryer, preheat it to 350°F (175°C). Place the casserole in the air fryer basket and heat for 10-12 minutes, shaking the basket halfway through to ensure even heating.
