This sausage brunch casserole is a delightful and hearty dish perfect for a weekend breakfast or brunch. Combining savory sausage, fluffy eggs, and gooey cheese, this casserole is sure to be a crowd-pleaser. The addition of bread cubes gives it a satisfying texture, making it a complete meal in one dish.
Most of the ingredients for this recipe are common pantry staples, but you may need to pick up a few items if you don't have them on hand. Make sure to get crumbled sausage from the meat section, and if you don't have day-old bread, you can buy a fresh loaf and let it sit out overnight. Shredded cheddar cheese can be found in the dairy aisle.

Ingredients For Sausage Brunch Casserole
Sausage: Crumbled and cooked, this adds a savory and meaty flavor to the casserole.
Eggs: Beaten, they provide structure and richness to the dish.
Milk: Adds creaminess and helps bind the ingredients together.
Salt: Enhances the overall flavor of the casserole.
Black pepper: Adds a touch of heat and depth to the flavor profile.
Cheddar cheese: Shredded, it melts beautifully and adds a cheesy goodness.
Bread cubes: Day-old, they absorb the egg mixture and add texture to the casserole.
Technique Tip for This Brunch Casserole
When preparing the bread cubes, ensure they are truly day-old or slightly stale. Fresh bread can become too soggy during baking, while slightly dried-out bread will absorb the egg mixture better, resulting in a more cohesive and less mushy casserole. If you don't have day-old bread, you can quickly dry out fresh bread by spreading the cubes on a baking sheet and toasting them in a 300°F (150°C) oven for about 10 minutes.

How to Store / Freeze This Brunch Casserole
Allow the sausage brunch casserole to cool completely before storing. This helps prevent condensation, which can make the dish 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.
If you plan to freeze the casserole, cut it into individual portions. This makes reheating easier and more convenient.
Wrap each portion tightly with plastic wrap, then place them in a resealable freezer bag or an airtight container. Label with the date to keep track of freshness.
For best results, consume the frozen casserole within 2-3 months. Beyond this period, the texture and flavor may begin to degrade.
To reheat from the refrigerator, preheat your oven to 350°F (175°C). Place the casserole in an oven-safe dish and cover with foil. Heat for about 20-25 minutes or until warmed through.
For reheating from frozen, it's best to thaw the casserole in the refrigerator overnight. Once thawed, follow the same reheating instructions as for refrigerated portions.
If you're in a hurry, you can reheat the frozen casserole directly. Preheat your oven to 350°F (175°C), cover the dish with foil, and bake for 45-60 minutes, or until heated through. Check occasionally to ensure it doesn't dry out.
For a quicker option, use the microwave. Place a portion on a microwave-safe plate, cover with a microwave-safe lid or another plate, and heat on medium power for 3-5 minutes, checking and stirring halfway through.
To maintain the casserole's texture, avoid reheating multiple times. Only reheat the portion you plan to eat immediately.
