This bacon breakfast casserole is a hearty and delicious way to start your day. Combining the savory flavors of bacon, cheddar cheese, and eggs with the comforting texture of bread cubes, this dish is perfect for a family breakfast or brunch. It's easy to prepare and can be made ahead of time, making your morning routine a breeze.
Most of the ingredients for this recipe are common pantry staples, but you might need to pick up some day-old bread if you don't have any on hand. Day-old bread is preferred because it absorbs the egg mixture better, giving the casserole a perfect texture. Additionally, make sure you have enough shredded cheddar cheese and cooked bacon ready before you start.

Ingredients For Bacon Breakfast Casserole
Bacon: Adds a savory and smoky flavor to the casserole.
Eggs: Bind the ingredients together and provide richness.
Milk: Helps to create a creamy texture in the casserole.
Shredded cheddar cheese: Adds a sharp and tangy flavor.
Salt: Enhances the overall flavor of the dish.
Black pepper: Adds a hint of spice and depth.
Day-old bread cubes: Absorb the egg mixture and provide structure to the casserole.
Technique Tip for This Breakfast Casserole
To ensure your casserole has a perfect texture, make sure the bread cubes are truly day-old or slightly stale. Fresh bread can become too soggy when mixed with the egg and milk mixture. If you don't have day-old bread, you can dry out fresh bread by cutting it into cubes and baking it in a 300°F (150°C) oven for about 10 minutes, or until it's dry but not browned. This will help the casserole hold its shape and give it a delightful texture.

How to Store / Freeze This Breakfast Casserole
Allow the bacon breakfast casserole to cool completely before storing. This helps prevent condensation, which can make the dish soggy.
For short-term storage, cover the casserole dish tightly with plastic wrap or aluminum foil. Alternatively, transfer the casserole to an airtight container. Store 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, then place them in a freezer-safe bag or container. Label with the date to keep track of freshness.
When ready to enjoy, thaw the frozen portions in the refrigerator overnight. This gradual thawing helps maintain the texture and flavor of the casserole.
Reheat the thawed casserole portions in the microwave or oven. For the microwave, place a portion on a microwave-safe plate and heat on high for 1-2 minutes, or until heated through. For the oven, preheat to 350°F (175°C) and bake for about 15-20 minutes, or until warmed thoroughly.
If you prefer a crispier texture, reheat the casserole in the oven rather than the microwave. This will help maintain the golden, crunchy top layer.
Avoid refreezing the casserole once it has been thawed, as this can affect the quality and safety of the dish.
