Ingredients For Bacon Breakfast Casserole
Bacon: Adds a savory and crispy element to the casserole.
Eggs: The base that binds all the ingredients together.
Milk: Provides moisture and helps create a custard-like texture.
Salt: Enhances the overall flavor of the dish.
Black pepper: Adds a touch of spice and depth to the flavor.

Technique Tip for This Recipe
When cooking bacon, ensure you start with a cold skillet. This allows the fat to render out slowly, resulting in evenly cooked, crispy bacon. Additionally, when whisking the eggs and milk together, make sure to whisk thoroughly to incorporate air, which will make the casserole light and fluffy.

How to Store or Freeze This Casserole
Allow the bacon breakfast casserole to cool completely after baking. This ensures that condensation doesn't form inside the storage container, which could make the bread 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.
To reheat, preheat your oven to 350°F (175°C). Place the casserole in an oven-safe dish and cover with foil to prevent drying out. Heat for about 20-25 minutes or until warmed through. Alternatively, individual portions can be microwaved for 1-2 minutes.
For freezing, cut the cooled casserole into individual portions. Wrap each portion tightly in plastic wrap, then place in a freezer-safe bag or container. Label with the date and contents.
When ready to enjoy, thaw the frozen portions in the refrigerator overnight. Reheat in the oven at 350°F (175°C) for about 20-25 minutes, or until heated through. Microwaving is also an option, but the texture may be slightly different.
If you prefer to freeze the entire casserole, wrap the entire dish tightly in plastic wrap and then in aluminum foil. This double layer helps prevent freezer burn. Freeze for up to 2-3 months.
To reheat a whole frozen casserole, remove the plastic wrap and cover with foil. Bake at 350°F (175°C) for about 60-75 minutes, or until heated through. Remove the foil during the last 10-15 minutes to allow the top to crisp up.
Always ensure the casserole reaches an internal temperature of 165°F (74°C) when reheating to ensure food safety.
How to Reheat Leftovers
Oven Method: Preheat your oven to 350°F (175°C). Place the leftover bacon breakfast casserole in an oven-safe dish. Cover it with aluminum foil to prevent it from drying out. Bake for about 20-25 minutes, or until heated through. Remove the foil for the last 5 minutes to regain some of that golden-brown crispiness.
Microwave Method: Place a portion of the casserole on a microwave-safe plate. Cover it with a microwave-safe lid or a damp paper towel to keep it moist. Heat on medium power for 1-2 minutes, checking halfway through. If it's not hot enough, continue heating in 30-second increments until warmed through.
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 casserole slices in the skillet and cover with a lid. Cook for about 5-7 minutes, flipping halfway through, until both sides are heated and slightly crispy.
Air Fryer Method: Preheat your air fryer to 350°F (175°C). Place the casserole pieces in the air fryer basket in a single layer. Heat for about 5-7 minutes, shaking the basket halfway through, until the casserole is hot and the edges are crispy.
Toaster Oven Method: Preheat your toaster oven to 350°F (175°C). Place the casserole on a piece of aluminum foil or a small baking sheet. Cover loosely with foil to prevent drying. Heat for about 15-20 minutes, removing the foil for the last 5 minutes to crisp up the top.
