Ingredients You’ll Need

Each ingredient in this Sausage Hash Brown Breakfast Casserole brings its own magic, from savory depth to creamy richness. The beauty is in the balance: simple pantry staples that together create something both cozy and celebratory.

• Breakfast Sausage: Adds a boldly savory and satisfying flavor that’s the signature of this casserole.
• Frozen Shredded Hash Browns: These provide the golden, tender (and wonderfully convenient) base—make sure they’re thawed for even baking.
• Shredded Cheddar Cheese: Melts to perfection for cheesiness in every layer; use sharp cheddar for extra punch.
• Large Eggs: Whisked into the casserole to bind everything together into a fluffy, custardy delight.
• Milk: Gives the egg mixture that creamy, rich lift you want in a brunch bake.
• Garlic Powder: Just the right touch of background warmth to bring out all the other flavors.
• Onion Powder: Rounds out the flavor profile and gives subtle depth with every bite.
• Salt: Enhances the savory goodness of the sausage and the cheese.
• Black Pepper: For a flicker of spice that perfectly complements the other seasonings.
• Cooking Spray: Makes sure your casserole slides right out of the dish—no sticking, just easy serving.

How to Make Sausage Hash Brown Breakfast Casserole

Step 1: Prep Your Baking Dish & Oven

To get started, preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with cooking spray, making sure every corner gets coated. This step makes serving and cleanup a breeze and ensures your Sausage Hash Brown Breakfast Casserole lifts out beautifully!

Step 2: Brown the Sausage

Heat a large skillet over medium, then crumble in your breakfast sausage. Cook, stirring gently, until it’s all browned and no longer pink. Don’t forget to drain off any excess grease to keep the casserole from feeling too heavy. The cooked sausage should be flavorful and just a little crispy around the edges—perfect for building those savory layers!

Step 3: Assemble the Base

In a large bowl, combine your thawed hash browns, browned sausage, and shredded cheddar cheese. Stir everything together until well mixed, and then spread this mixture evenly into your prepared baking dish. The cheese will hug the hash browns and sausage, promising extra richness in every forkful.

Step 4: Mix the Egg Mixture

Whisk the eggs, milk, garlic powder, onion powder, salt, and black pepper in a separate bowl until smooth and fully blended. This simple mixture is key to creating the creamy, fluffy texture that makes Sausage Hash Brown Breakfast Casserole so irresistible.

Step 5: Layer and Bake

Pour the egg mixture slowly and evenly over the hash brown, sausage, and cheese base. Gently tilt the dish if needed to help the egg mixture settle in around all the ingredients. Bake uncovered for 45–50 minutes, or until the center is set and the top is gloriously golden with bubbling edges. Let your casserole cool for 5–10 minutes before slicing to allow everything to set perfectly.

How to Serve Sausage Hash Brown Breakfast Casserole

Garnishes

This casserole is delicious as-is, but a sprinkle of fresh chopped parsley or sliced green onions adds a dash of color and a touch of freshness. For a little extra heat, you can scatter some red pepper flakes or drizzle a little hot sauce across the top right before serving.

Side Dishes

I love serving Sausage Hash Brown Breakfast Casserole alongside a fresh fruit salad or with zesty citrus wedges. Fluffy biscuits or a simple green salad make perfect additions, too—the contrast is light and satisfying, letting the casserole shine as the star of your breakfast spread.

Creative Ways to Present

If you’re hosting a brunch, slice the casserole into neat squares and place them on a platter with fun cocktail picks. Try cutting it into bite-sized cubes for a finger-food option at parties, or bake mini versions in muffin tins for individual servings—same cozy flavor, perfectly portioned!

Make Ahead and Storage

Storing Leftovers

Leftover Sausage Hash Brown Breakfast Casserole keeps beautifully! Allow it to cool completely, then transfer slices to an airtight container and refrigerate for up to four days. It makes an awesome, grab-and-go breakfast through the week.

Freezing

For longer storage, freeze leftovers in tightly wrapped individual portions or the entire casserole (after baking and cooling). Just cover well with foil or plastic wrap, and keep for up to two months. When ready to enjoy, thaw overnight in the fridge for best texture.

Reheating

Reheat individual slices in the microwave on medium power until just heated through, or warm larger portions in a low oven (about 325°F) covered with foil to prevent drying out. Either way, it’ll taste just as comforting as when fresh from the oven!

FAQs

Can I assemble the Sausage Hash Brown Breakfast Casserole the night before?

Absolutely! Prep everything the night before, cover tightly, and refrigerate. In the morning, just pop it in the oven and follow the baking instructions—perfect for holiday breakfasts or easy entertaining.

Can I substitute the sausage in the recipe?

Yes! Feel free to swap in turkey sausage, plant-based sausage, or even chopped bacon. The flavor profile changes a bit, but the casserole turns out just as hearty and delicious.

What can I add to customize the casserole?

This dish is endlessly adaptable: try adding sautéed bell peppers, spinach, or mushrooms for extra color and nutrition. Switch up the cheeses or throw in some diced jalapeños for a spicy kick!

Can I use fresh potatoes instead of frozen hash browns?

You sure can. Peel and shred your potatoes, then squeeze out as much moisture as possible using a clean kitchen towel before mixing them in, so your casserole stays nice and fluffy.

How do I know when the casserole is fully baked?

The center should be puffed up, set, and not jiggly when gently shaken. You can also insert a knife into the center—if it comes out clean with no wet egg mixture, it’s ready to come out of the oven.

Final Thoughts

Bringing this Sausage Hash Brown Breakfast Casserole to your table is like serving a warm hug to everyone around you. Whether you’re sharing it for a special celebration or just making an ordinary morning fabulous, it never fails to impress with simplicity and heartiness. Give it a try—you may just start a new breakfast tradition!
