The beauty of this Sausage Breakfast Casserole Recipe lies in its simplicity and hearty ingredients. Each component plays a crucial role in creating a balanced dish full of flavor, texture, and color, from the savory sausage to the cheesy topping.
- 1 pound breakfast sausage: Choose a quality sausage to ensure the base flavor is robust and savory.
- 3 cups frozen shredded hash browns: These create a crispy, golden foundation that holds the casserole together beautifully.
- 8 large eggs: Eggs act as the binder, lending creaminess and structure to the casserole.
- 2 cups whole milk: Whole milk adds richness and a smooth texture to the egg mixture.
- 1 teaspoon salt: Enhances all the other flavors without overpowering.
- 1/2 teaspoon black pepper: Brings a gentle heat and depth to the dish.
- 2 cups shredded cheddar cheese: Sharp cheddar melts into gooey, golden perfection, topping the casserole with a delightful cheesiness.
How to Make Sausage Breakfast Casserole Recipe
Step 1: Cook the Sausage
Start by heating a large skillet over medium heat. Add the breakfast sausage and break it up as it cooks until it’s nicely browned and fully crumbled. Browning the sausage thoroughly is important to develop that rich flavor and a slight crispness that will add wonderful texture later. Once done, drain any excess fat and set the sausage aside while you prepare the rest.
Step 2: Whisk the Egg Mixture
In a medium bowl, crack in the eggs and add the whole milk along with salt and pepper. Whisk this mixture until everything is fully combined and smooth. This mixture will soak into the hash browns and sausage, binding the casserole with a creamy custard-like texture once baked.
Step 3: Prepare the Baking Dish
Grease a 9×13-inch baking dish liberally to prevent sticking. Then, evenly spread the frozen shredded hash browns in the bottom of the dish. This layer acts as the crispy base for the casserole and will become beautifully golden in the oven.
Step 4: Layer the Sausage and Cheese
Sprinkle the cooked sausage evenly over the hash browns, ensuring every bite will have some meaty goodness. Follow this by generously topping the sausage layer with shredded cheddar cheese, which will melt throughout the casserole and create that irresistible cheesy crust you’re after.
Step 5: Add the Egg Mixture
Slowly pour the egg mixture over all the layers, letting it seep between the cheese, sausage, and hash browns evenly. This step ensures every element is moistened and will bake together into a cohesive dish with a creamy center and crispy edges.
Step 6: Bake the Casserole
Place the casserole in your preheated oven at 350°F (175°C) and bake for about 45 to 50 minutes. You’ll know it’s ready when the center is set—no longer jiggly—and the top is a gorgeous golden brown. This baking time allows the flavors to meld while keeping the casserole rich and tender inside.
Step 7: Let it Rest
Once out of the oven, give your dish about 10 minutes to rest before slicing and serving. This pause helps the casserole firm up slightly, making it easier to cut perfect portions that hold their shape but remain creamy inside.
How to Serve Sausage Breakfast Casserole Recipe

Garnishes
A fresh touch goes a long way! Sprinkle chopped green onions or fresh parsley on top for a burst of color and mild oniony flavor that pairs beautifully with the sausage and cheese. Adding a dollop of sour cream or a spoonful of salsa can elevate the flavors and add a nice creamy or tangy contrast.
Side Dishes
Serve this casserole alongside fresh fruit salad or crispy bacon for a balanced breakfast spread. A simple green salad with a light vinaigrette also works well, providing a refreshing crispness to cut through the richness of the casserole.
Creative Ways to Present
Try serving the Sausage Breakfast Casserole Recipe in individual ramekins for a charming presentation perfect for brunch parties. Another fun idea is to cut the casserole into squares and skewer each with a small cocktail fork for easy grab-and-go bites. This dish also pairs wonderfully with a mimosa or fresh squeezed orange juice to brighten the meal.
Make Ahead and Storage
Storing Leftovers
Leftover casserole can be stored in an airtight container in the refrigerator for up to 3 days. Make sure to cool it completely before covering to avoid sogginess. Reheat individual portions in the microwave or oven for a quick and satisfying breakfast the next day.
Freezing
This Sausage Breakfast Casserole Recipe freezes beautifully. Wrap tightly with plastic wrap and foil, or store in a freezer-safe container, and freeze for up to 2 months. When ready to enjoy, thaw overnight in the refrigerator before reheating to preserve texture and flavor.
Reheating
To reheat, cover the casserole with foil and warm in a 350°F (175°C) oven until heated through, about 15-20 minutes depending on the portion size. For individual servings, the microwave also works well—just be mindful to prevent drying out by adding a small splash of water or covering the dish.
FAQs
Can I make this casserole vegetarian?
Absolutely! Simply replace the sausage with sautéed mushrooms, diced bell peppers, or a plant-based sausage substitute to keep the dish flavorful and hearty without meat.
What type of cheese works best in this recipe?
While shredded cheddar cheese is traditional and delicious, feel free to experiment with Monterey Jack, mozzarella, or a sharp gouda for different textures and flavor profiles.
Can I use fresh potatoes instead of frozen hash browns?
Yes, just make sure to shred fresh potatoes and squeeze out excess moisture before using. This ensures the casserole won’t become watery and will have that desirable crispy edge.
Is this casserole suitable for meal prepping?
Definitely! Prepare the casserole fully, then refrigerate and bake fresh when you’re ready. It’s a great way to save time on busy mornings while enjoying a homemade meal.
How can I make the casserole extra fluffy?
Whisk the eggs and milk mixture vigorously before pouring and consider adding a tablespoon of flour or baking powder for a lighter texture. Freshly grated cheese also helps with fluffiness as it melts evenly throughout the casserole.
