- 1 teaspoon salt: Enhances all the flavors and ensures a well-seasoned dish.

How to Make Sausage Breakfast Casserole Recipe
Step 1: Cook the Sausage
Start by heating a large skillet over medium heat and cooking the breakfast sausage, breaking it into crumbles as it browns. This step is essential to develop the sausage’s full flavor and texture before it goes into the casserole. Once cooked through and browned, drain off any excess fat and set the sausage aside to cool slightly.
Step 2: Whisk the Egg Mixture
While the sausage cooks, whisk together the eggs, whole milk, salt, and pepper in a large bowl. This custard-like mixture will bind all the ingredients and set perfectly in the oven, so make sure it’s well combined and smooth for an even bake.
Step 3: Prepare the Baking Dish
Grease a 9×13-inch baking dish with butter or non-stick spray to prevent sticking. Evenly spread the frozen shredded hash browns across the bottom, creating a crispy, hearty base that will soak up all the delicious flavors from the layers above.
Step 4: Layer the Sausage and Cheese
Distribute the cooked sausage evenly over the hash browns, then sprinkle the shredded cheddar cheese on top. This layering ensures every slice has a perfect bite of meat and cheese, mingling beautifully during baking.
Step 5: Pour the Egg Mixture
Carefully pour the whisked egg and milk mixture over the layered ingredients. Pour slowly and evenly to allow the liquid to seep through the hash browns and surround the sausage and cheese, setting the stage for a cohesive, tender bake.
Step 6: Bake to Perfection
Bake the casserole in a preheated oven at 350°F (175°C) for 45 to 50 minutes. You’ll know it’s done when the center is set, and the top turns a lovely golden brown. This slow baking ensures the eggs cook through without overcooking and the cheese melts into irresistibly gooey pockets.
Step 7: Rest Before Serving
Once out of the oven, let the casserole rest for about 10 minutes before slicing. This resting time helps the casserole set a bit more for clean, beautiful slices and allows the flavors to settle and mingle even further. Then, it’s time to dig in and enjoy!
How to Serve Sausage Breakfast Casserole Recipe

Garnishes
Fresh garnishes bring brightness and contrast to this rich casserole. Try a sprinkle of chopped fresh parsley or chives for a pop of color and mild herbal notes. For a bit of creaminess and tang, a dollop of sour cream or a light drizzle of hot sauce elevates each forkful delightfully.
Side Dishes
This casserole is quite filling on its own, but you can round out your breakfast spread with some fresh fruit salad or sliced avocado for refreshing balance. A simple green salad or roasted tomatoes also complement the savory depth of the casserole beautifully, adding freshness and color to your plate.
Creative Ways to Present
If you’re serving a brunch crowd, consider presenting the casserole on a rustic wooden board with small bowls of garnish toppings alongside for a fun, interactive meal. You can also slice the casserole into individual portions, placing each on colorful plates paired with small side servings, making the experience feel special and festive.
Make Ahead and Storage
Storing Leftovers
Leftover sausage breakfast casserole keeps wonderfully in the refrigerator for up to 4 days when stored in an airtight container. This makes it an ideal make-ahead meal or a convenient next-day breakfast, ready to perk you up without extra cooking.
Freezing
This recipe also freezes beautifully for longer storage. Cool the casserole completely, then wrap tightly with plastic wrap and aluminum foil or place in a freezer-safe container. It will maintain optimal flavor and texture for up to 2 months in the freezer.
Reheating
To reheat, thaw overnight in the fridge if frozen, then warm slices individually in the microwave or cover with foil and bake in the oven at 350°F (175°C) until hot and bubbly, about 15 to 20 minutes. This helps revive the flavors and keeps the texture just right.
FAQs
Can I use a different type of sausage?
Absolutely! While breakfast sausage brings a classic flavor, you can substitute with spicy Italian sausage or even turkey sausage for a lighter option. Just make sure it’s cooked thoroughly before layering.
Can I make this casserole vegetarian?
Yes! Simply omit the sausage and consider adding sautéed mushrooms, bell peppers, or crumbled veggie sausage to maintain hearty texture and flavor.
Is it possible to use fresh potatoes instead of frozen hash browns?
Definitely. Just grate fresh potatoes, squeeze out excess moisture, and use the same quantity. Keep in mind fresh potatoes might yield a slightly different texture but still delicious.
Can I prepare this casserole the night before?
Yes, layering everything the night before and refrigerating overnight is a great time saver. Just cover tightly and bake fresh in the morning, adding a few extra minutes to the bake time if needed.
What can I substitute for cheddar cheese?
Feel free to use Monterey Jack, Colby, or a cheese blend you love. These cheeses melt well and complement the flavors nicely, offering slight variations in taste and creaminess.
