1 lb breakfast sausage: Provides that rich, savory base that carries the dish.
8 large eggs: The binding and fluffy backbone of the casserole.
2 cups milk (whole or 2%): Keeps everything tender and moist as it bakes.
2 cups shredded cheddar cheese: Melts into gooey pockets of flavor that everyone adores.
6 cups bread cubes (day-old preferred): Absorb the egg mixture and add a delightful texture contrast.
½ tsp salt: Balances the flavors perfectly.
¼ tsp black pepper: Adds a gentle kick without overpowering.
Optional add-ins: Diced bell peppers, green onions, spinach, or hash browns to personalize the casserole and add a pop of color and nutrition.

How to Make Sausage and Egg Breakfast Casserole Recipe

Step 1: Prepare the Oven and Baking Dish

Start by preheating your oven to 350°F (175°C) and greasing a 9×13-inch baking dish. This step ensures your casserole won’t stick and will brown evenly, giving that inviting golden top everyone loves.

Step 2: Cook the Sausage

Heat a skillet over medium heat and cook the breakfast sausage until it’s thoroughly browned, breaking it apart as it cooks. Draining the excess fat prevents sogginess, letting the sausage’s savory flavor shine through beautifully in the casserole.

Step 3: Assemble the Layers

Spread the bread cubes evenly across the bottom of the baking dish to create a sturdy base. Then sprinkle the browned sausage evenly over the bread, followed by generous layers of shredded cheddar cheese. This layering ensures every bite delivers a perfect balance of textures and flavors.

Step 4: Mix and Pour the Egg Mixture

Whisk together the eggs, milk, salt, and black pepper until smooth and combined. Pour the mixture evenly over the layered bread, sausage, and cheese, allowing the bread to soak up the custardy egg mixture. This soak-in step is key to that tender, fluffy center.

Step 5: Bake to Perfection

Place the casserole in the oven and bake for 40 to 45 minutes, or until the eggs are set and the top turns a light golden brown. The smell during baking is already a signal that breakfast is going to be unforgettable!

Step 6: Rest and Serve

Once baked, allow the casserole to rest for about 5 minutes before slicing. This resting time lets everything settle, making it easier to cut and enhancing the blend of flavors and textures in each portion.

Garnishes

Adding fresh garnishes takes your casserole from great to unforgettable. Sprinkle chopped green onions or fresh parsley on top for a splash of color and a fresh herbal note that balances the richness. A dash of hot sauce or salsa on the side can also add just the right amount of zing!

Side Dishes

Pair this classic casserole with light sides like fresh fruit salad, mixed greens with a tangy vinaigrette, or even crispy breakfast potatoes for a more hearty meal. These sides provide contrast and round out the meal without overwhelming those delicious eggs and sausage.

Creative Ways to Present

Feeling playful? Try serving individual portions in ramekins for a personal touch, or layer this dish with other ingredients such as sautéed mushrooms or caramelized onions before baking. For a fun twist, add a sprinkle of your favorite cheese blend on top halfway through baking to create a bubbly, golden crust.

Make Ahead and Storage

Storing Leftovers

After enjoying your delicious casserole, don’t pack away those leftovers just yet. Store airtight in the refrigerator for up to 3 days. This dish reheats wonderfully and maintains its flavor and texture, making it perfect for easy breakfasts later in the week.

Freezing

If you want to plan even further ahead, the Sausage and Egg Breakfast Casserole Recipe freezes beautifully. Assemble it fully, then wrap tightly with foil and plastic wrap before freezing for up to 3 months. When ready to use, thaw overnight in the fridge before baking as directed.

Reheating

To reheat, simply warm individual portions in the microwave for 1 to 2 minutes or bake the whole dish at 350°F until warmed through. This ensures you get that fresh-from-the-oven taste every time, with melty cheese and fluffy eggs just as delightful as day one.

FAQs

Can I use a different type of sausage in this recipe?

Absolutely! Feel free to swap breakfast sausage for Italian sausage, turkey sausage, or even a plant-based alternative to fit your taste or dietary needs. Just adjust seasoning if your sausage is already heavily seasoned.

What kind of bread works best for this casserole?

Day-old white or whole wheat bread works wonderfully because it soaks up the egg mixture without becoming mushy. You can also experiment with sourdough or gluten-free bread if preferred.

Can I make this recipe vegetarian?

Sure thing! Simply omit the sausage and add hearty vegetables like mushrooms, zucchini, or roasted peppers to keep it flavorful and filling.

Is it possible to prepare this the night before?

Yes! Preparing the casserole the night before and refrigerating it not only saves time but also lets the flavors meld beautifully. Just cover it tightly and bake fresh the next morning.

How do I know when the casserole is fully cooked?

The casserole is done when the eggs are set and no longer jiggly in the center. A light golden top is a good sign, but to be sure, you can insert a knife in the middle—it should come out clean.
