- 2 cups shredded cheddar cheese: Sharp or mild, the cheese melts beautifully to create gooey pockets of deliciousness.
- 1/2 teaspoon salt: Enhances the natural flavors without overpowering.
- 1/4 teaspoon black pepper: Adds just the right touch of warmth and spice.

How to Make Delicious Sausage and Egg Breakfast Casserole Recipe
Step 1: Cook the Sausage
Start by heating a skillet over medium heat and cooking the breakfast sausage until it’s nicely browned and crumbled. The aroma of sizzling sausage sets the tone for the dish, and draining the excess grease ensures your casserole will be flavorful but not greasy. Set the cooked sausage aside to cool slightly while you prep the bread.
Step 2: Prepare the Bread Layer
Cube the six slices of white sandwich bread into bite-sized pieces. Then, evenly layer these cubes in a greased 9×13-inch baking dish. This bread base will soak up the savory sausage flavors and the creamy egg mixture, creating a soft and satisfying texture throughout the casserole.
Step 3: Assemble Sausage and Cheese Layers
Next, sprinkle the browned sausage generously over the layer of bread cubes. Follow this by sprinkling the shredded cheddar cheese evenly on top. The cheese will melt during baking, creating gooey, cheesy pockets that everyone will love.
Step 4: Mix and Pour the Egg Mixture
In a mixing bowl, whisk together the eggs, whole milk, salt, and black pepper until perfectly smooth. This mixture is the heart of the casserole, infusing it with richness and binding the ingredients together. Pour it evenly over the bread, sausage, and cheese layers. Press the layers gently so the bread absorbs the egg mixture thoroughly.
Step 5: Refrigerate Before Baking
Cover the casserole and refrigerate it for at least 2 hours or, even better, overnight. This resting time allows the bread to soak up the egg custard fully, ensuring a moist, custardy interior that’s bursting with flavor once baked.
Step 6: Bake to Golden Perfection
When ready to bake, preheat your oven to 350°F (175°C). Uncover the casserole and bake it for about 45 to 50 minutes or until the top is golden and the custard is set. The aroma filling your kitchen at this stage is truly irresistible!
Step 7: Let it Rest and Garnish
Once out of the oven, let the casserole cool for 10 minutes. This helps it set up for clean slicing and serving. If you like, sprinkle chopped parsley on top to add a pop of fresh color and a light herbal note that complements the rich flavors beautifully.
How to Serve Delicious Sausage and Egg Breakfast Casserole Recipe
Garnishes
A sprinkle of fresh parsley is a simple yet elegant way to finish this casserole. If you want to add even more flavor, consider a dusting of smoked paprika or a few slices of green onion. These small touches elevate the dish visually and flavor-wise, making it feel special every time.
Side Dishes
This casserole pairs wonderfully with light, fresh sides like a mixed green salad tossed with a tangy vinaigrette or a crisp fruit salad to balance the richness. For a heartier brunch, serve it alongside roasted potatoes or buttered toast for extra comfort and variety.
Creative Ways to Present
For a festive brunch or family gathering, bake the casserole in individual ramekins for personal servings. You can also layer additional veggies like bell peppers or spinach in the mix to add color and nutrients while keeping the comforting base of sausage and egg. Either way, this dish is a guaranteed breakfast showstopper.
Make Ahead and Storage
Storing Leftovers
After enjoying this Delicious Sausage and Egg Breakfast Casserole Recipe, store any leftovers in an airtight container in the refrigerator. It will keep well for 3 to 4 days, making for easy next-day breakfasts or quick lunches that still taste fresh and delicious.
Freezing
You can freeze the casserole either before or after baking. Freeze it in a tightly wrapped container or foil to protect against freezer burn. When stored properly, the casserole remains flavorful for up to two months. Just remember to thaw it overnight in the refrigerator before reheating for best results.
Reheating
Reheat individual portions in the microwave until warmed through, or place leftovers in a preheated 350°F oven covered loosely with foil for about 15-20 minutes. You want it hot and melty without drying it out. This makes leftovers just as comforting as the first serving.
FAQs
Can I use different types of bread for the casserole?
Absolutely! While white sandwich bread is traditional for its texture and absorbency, you can substitute with whole wheat, sourdough, or even croissants for a richer flavor. Just make sure the bread cubes are relatively fresh to soak up the egg mixture properly.
Is it possible to make this casserole vegetarian?
Yes! Simply omit the sausage and add your favorite vegetables like mushrooms, spinach, or bell peppers. You can also use vegetarian sausage alternatives for the same savory punch without the meat.
Can I prepare this casserole the night before?
Definitely. One of the best parts of this recipe is its make-ahead convenience. Assemble the casserole the night before, refrigerate it to let flavors meld, and bake it fresh in the morning for a stress-free breakfast.
What type of cheese works best in this recipe?
Cheddar cheese is classic here, providing a nice sharpness and great melting quality. However, feel free to experiment with Monterey Jack, mozzarella, or a blend if you prefer a different flavor profile or a creamier texture.
How can I make this healthier?
To lighten up the casserole, use turkey or chicken sausage, replace whole milk with a lower-fat option, and add plenty of veggies to increase fiber and nutrients. Using whole grain bread also boosts the health factor without sacrificing taste.
