Ingredients You’ll Need
These ingredients are straightforward but crucial for creating the perfect balance of flavor, texture, and color in your casserole. Each one plays its part, from the savory sausage to the creamy eggs and melty cheese, ensuring every forkful is packed with deliciousness.
- Breakfast sausage (1 pound): Pork or turkey sausage provides a flavorful, protein-packed base that complements the potatoes perfectly.
- Frozen hash browns (30 oz, thawed): These add a wonderfully crispy and tender texture that holds up beautifully in the casserole.
- Large eggs (8): Eggs bind everything together and bring a rich, creamy consistency.
- Milk or half-and-half (1 ½ cups): Using half-and-half adds extra creaminess, but milk works great for a lighter version.
- Salt (1 teaspoon): Enhances all the flavors, making each ingredient shine.
- Black pepper (½ teaspoon): Adds a subtle kick without overpowering the dish.
- Garlic powder (½ teaspoon): Gives a gentle depth of savory flavor.
- Onion powder (½ teaspoon): Adds a mild sweetness and aroma that complements the sausage.
- Shredded cheddar cheese (1 ½ cups): Brings melty, sharp richness that’s absolutely irresistible.
- Shredded mozzarella cheese (½ cup, optional): Adds gooey stretchiness and a hint of mild creaminess.
How to Make Sausage Hash Brown Breakfast Casserole Recipe
Step 1: Brown the Sausage
Begin by heating a large skillet over medium heat. Add your breakfast sausage and cook it until it’s fully browned, breaking it apart with a spoon as it cooks. This step infuses the dish with that signature savory flavor and ensures every bite of your casserole has a wonderful meaty texture.
Step 2: Prepare the Hash Browns
After draining excess grease from the sausage, make sure your frozen hash browns are completely thawed and patted dry. This prevents unwanted moisture that could make your casserole soggy. Then, evenly spread the hash browns in a well-greased 9×13-inch baking dish to form a golden, crispy crust layer.
Step 3: Mix the Egg Base
In a large bowl, whisk together the eggs, milk (or half-and-half), salt, black pepper, garlic powder, and onion powder until smooth and well combined. This creamy mixture is the glue that holds each delicious component together, permeating the casserole with flavor and moisture.
Step 4: Assemble the Casserole
Sprinkle the cooked sausage evenly over the hash brown base, then pour the seasoned egg mixture over the entire dish. Finally, scatter shredded cheddar and optional mozzarella cheese on top. These layers create a rich, cheesy finish you’ll love.
Step 5: Bake to Perfection
Preheat your oven to 375°F (190°C). Place the casserole in the oven uncovered and bake for 40 to 45 minutes until the eggs are fully set and the cheese is golden and bubbling. Let the casserole rest for about 5 minutes before slicing—it helps everything settle, making serving a breeze.
How to Serve Sausage Hash Brown Breakfast Casserole Recipe

Garnishes
Enhance your casserole with a sprinkle of chopped green onions for fresh color and a mild onion flavor. A dollop of sour cream or a drizzle of hot sauce or salsa adds brightness and a little zing, perfect for those who love a bit of tang or heat.
Side Dishes
This casserole certainly stands strong on its own, but pairing it with fresh fruit or a crisp green salad balances the richness and adds a refreshing touch. Toasted English muffins or warm cinnamon rolls make sweet companions, turning your breakfast into a full feast.
Creative Ways to Present
Try baking this Sausage Hash Brown Breakfast Casserole Recipe in individual ramekins for a charming single-serve option.

Make Ahead and Storage
Storing Leftovers
Your leftover casserole stores beautifully in an airtight container in the refrigerator for up to 4 days. This makes it an excellent candidate for breakfast or brunch on busy mornings when you want something quick but homemade.
Freezing
To freeze, cool the casserole completely, then wrap it tightly with plastic wrap and aluminum foil or store in a freezer-safe container. It will keep well for up to 2 months, allowing you to enjoy this breakfast favorite anytime you need a hearty, ready-to-bake meal.
Reheating
Reheat individual slices in the microwave for about 1 to 2 minutes until warmed through, or reheat in a 350°F oven uncovered for 15 to 20 minutes to preserve that crispy top. This restores the casserole’s delightful texture and melty, cheesy goodness.
FAQs
Can I make this casserole vegetarian?
Absolutely! Substitute the sausage with sautéed mushrooms, diced bell peppers, or a plant-based sausage alternative to keep the hearty flavor without the meat.
Is it okay to use fresh potatoes instead of frozen hash browns?
Yes, but be sure to shred and parboil or sauté them first to remove excess moisture and achieve the right texture before assembling the casserole.
Can I prepare the casserole the night before?
Definitely! Assemble it the night before, cover tightly, and refrigerate. Bake it fresh in the morning, adding about 10 extra minutes to the baking time if it’s cold from the fridge.
What’s the best cheese to use?
Cheddar is a classic choice for its sharpness and meltability, but feel free to mix in mozzarella or even pepper jack for some extra creaminess or a little kick.
Can I add vegetables to the casserole?
Of course! Spinach, bell peppers, onions, or mushrooms make great additions. Just sauté them first to reduce moisture and enhance their flavors.
