Ingredients You’ll Need

These ingredients are straightforward and easy to find, yet each one plays a vital role in making this casserole irresistibly delicious. From the rich beef sausage to the creamy eggs and the sharp cheddar cheese, every component contributes to the vibrant flavors and textures that make this dish special.

8 large eggs: The eggs bind everything together and give the casserole a fluffy, tender texture.
1 pound beef sausage: Adds a robust, savory flavor and hearty protein to keep you full all morning.
1 1/2 cups whole milk or heavy cream: Infuses creaminess and richness into the egg mixture.
1 package (30 oz) frozen shredded hash browns, thawed: Provides a crispy, hearty base layer that contrasts perfectly with the soft eggs.
2 cups shredded cheddar cheese: Melts throughout the casserole, adding gooey, tangy goodness.
1 1/2 teaspoons salt: Enhances the flavors and balances the dish.
1 teaspoon black pepper: Adds a mild kick and depth of flavor.
1/4 teaspoon garlic powder: Brings a subtle savory warmth without overpowering the other flavors.

How to Make Hearty Winter Breakfast Casserole with Beef Sausage

Step 1: Cook the Sausage

Start by browning the beef sausage in a large skillet over medium-high heat. Breaking it apart with your spatula, cook until it’s fully browned and slightly crispy. This step is crucial for developing a rich, meaty flavor. Once cooked, drain off any excess grease to keep the casserole from becoming too oily, and set the sausage aside.

Step 2: Prepare the Hash Browns and Cheese Layer

Next, preheat your oven to 375°F (190°C). Spread the thawed shredded hash browns evenly across the bottom of a 9×13 inch baking dish. This creates a sturdy and delicious base. Scatter the browned beef sausage on top, then sprinkle with one cup of shredded cheddar cheese for that first burst of melty, cheesy flavor.

Step 3: Whisk the Eggs and Seasonings

In a large mixing bowl, combine the eggs, whole milk or heavy cream, salt, black pepper, and garlic powder. Whisk vigorously until the mixture is fully blended and slightly frothy. This mixture will seep through the layers, binding everything with rich creaminess and seasoning.

Step 4: Assemble the Casserole

Carefully pour the egg mixture over the layers in your baking dish. Make sure the liquid seeps down into every nook and cranny for even cooking. The eggs will soak into the hash browns and sausage, marrying all the components beautifully.

Step 5: Top with Cheese and Bake Covered

Sprinkle the remaining cup of shredded cheddar cheese evenly over the casserole’s surface. Cover the dish tightly with aluminum foil. This keeps the moisture in and helps the eggs cook through gently. Bake for 45 minutes to let those flavors meld and the casserole set up.

Step 6: Uncover and Finish Baking

Remove the foil and bake for another 15-20 minutes until the top turns golden brown and the casserole is bubbly and fully cooked. Let it rest for at least 10 minutes before slicing — this pause helps it firm up, making serving easier and keeping every slice intact.

How to Serve Hearty Winter Breakfast Casserole with Beef Sausage

Garnishes

To elevate the presentation and flavor, try sprinkling freshly chopped chives or parsley over the top after baking. A dollop of sour cream or a spoonful of salsa can also add a refreshing contrast to the rich, cheesy base.

Side Dishes

This casserole shines all on its own, but you can round out the meal with crisp fruit salad or sautéed greens. A warm muffin or a piece of crusty toast can make it feel even more substantial.

Creative Ways to Present

For brunch parties, cut the casserole into bite-sized squares and serve on a platter with toothpicks. Or, add a drizzle of hot sauce or a sprinkle of smoked paprika for an extra flavor kick. The possibilities to customize this dish are as welcoming as the casserole itself.

Make Ahead and Storage

Storing Leftovers

Wrap any leftover casserole tightly with plastic wrap or store it in an airtight container. It will keep well for up to four days in the refrigerator without losing its delicious texture.

Freezing

If you want to save this for a future breakfast, freeze the casserole either before baking or after cooking. Just cover it tightly with foil and plastic wrap to prevent freezer burn. It can last up to two months frozen, making meal prep a breeze on busy days.

Reheating

Reheat individual slices in the microwave for about 1-2 minutes or warm the whole dish in a 350°F (175°C) oven until heated through. To keep the top from drying out, cover loosely with foil when reheating in the oven.

FAQs

Can I use a different type of sausage?

Absolutely! While beef sausage offers a rich flavor, you can swap it for pork, turkey, or even a plant-based sausage depending on your preference. Just be mindful of the seasoning and fat content as it can affect the casserole’s taste and texture.

Is there a vegetarian version of this casserole?

Yes! Replace the beef sausage with sautéed vegetables like mushrooms, bell peppers, and onions or use a vegetarian sausage alternative. The cheese and eggs provide plenty of protein and flavor to keep it satisfying.

Can I prepare this casserole the night before?

Definitely. You can assemble the casserole and refrigerate it overnight. Just add a few extra minutes to the baking time the next morning since the casserole will be cold going into the oven.

What type of cheese works best?

Shredded cheddar cheese is my favorite for this casserole because it melts beautifully and has a nice sharp flavor. However, you can mix in Monterey Jack, mozzarella, or even a bit of Parmesan for a unique twist.

How do I know when the casserole is fully cooked?

The casserole is done when the eggs are fully set, and the top is golden brown and bubbly. You can also insert a knife into the center—if it comes out clean, your casserole is perfectly cooked.

This Hearty Winter Breakfast Casserole with Beef Sausage is more than just breakfast; it’s an experience of comfort and warmth perfect for cold mornings.
