How to Make It
Start by preheating your oven to 350°F and greasing a 9×13-inch baking dish. Brown the breakfast sausage in a large skillet over medium heat, breaking it into crumbles as it cooks.
In a large bowl, whisk together eggs, milk, sour cream, and all your seasonings until well combined. Stir in the thawed hashbrowns, cooked sausage, and half of both cheeses.
Pour everything into your prepared baking dish and spread it evenly. Top with the remaining cheese and bake for 45-50 minutes until golden and set in the center.

Ingredients
1 pound breakfast sausage (mild or spicy)
1 (30 oz) bag frozen hashbrowns, thawed
2 cups shredded cheddar cheese
1 cup shredded mozzarella cheese
6 large eggs
1 cup whole milk
1/2 cup sour cream
1/2 teaspoon garlic powder
1/2 teaspoon onion powder
1/2 teaspoon salt
1/4 teaspoon black pepper
2 tablespoons butter, melted (for greasing dish)
Optional: chopped green onions, fresh parsley for garnish
Directions
- Preheat oven to 350°F. Grease a 9×13-inch baking dish with melted butter and set aside.
- In a large skillet over medium heat, cook the breakfast sausage until browned and crumbly, about 8-10 minutes. Drain excess grease and set aside.
- In a large mixing bowl, whisk together eggs, milk, sour cream, garlic powder, onion powder, salt, and pepper until smooth and well combined.
- Add the thawed hashbrowns (make sure to squeeze out excess moisture), cooked sausage, 1 cup cheddar cheese, and 1/2 cup mozzarella cheese to the egg mixture. Stir until everything is evenly distributed.
- Pour the mixture into the prepared baking dish and spread evenly. Top with the remaining 1 cup cheddar and 1/2 cup mozzarella cheese.
- Bake uncovered for 45-50 minutes, until the casserole is golden brown on top and set in the center (a knife inserted should come out clean).
- Let the casserole rest for 5-10 minutes before slicing. Garnish with green onions or parsley if desired.
- Serve warm and enjoy!
Notes
- Make-Ahead: Assemble the casserole the night before, cover with foil, and refrigerate. Bake the next morning, adding 5-10 extra minutes to the cook time.
Freezing: Freeze unbaked casserole tightly wrapped for up to 3 months. Thaw overnight before baking. - Vegetable Add-Ins: Sauté diced bell peppers, onions, or mushrooms with the sausage for extra veggies.
Cheese Swaps: Use pepper jack, Swiss, Monterey Jack, or a Mexican blend for different flavor profiles.
Lighter Version: Use turkey sausage, low-fat cheese, and egg whites to reduce calories.

Tips for the Best Casserole
Make sure to thaw your hashbrowns completely and squeeze out any excess moisture. This prevents your casserole from becoming watery and ensures a perfect texture.
Let the casserole rest for 5-10 minutes after baking before slicing. This allows everything to set properly so you get clean, beautiful slices instead of a soupy mess.
For extra crispy edges, brush the top with melted butter before the final 10 minutes of baking. You can also broil it for 2-3 minutes at the end for an extra golden finish.
Storage and Reheating
Store leftover casserole in an airtight container in the refrigerator for up to 4 days. It reheats beautifully, making it perfect for quick breakfasts throughout the week.
To reheat, microwave individual portions for 1-2 minutes or warm in a 350°F oven for 15-20 minutes. Cover with foil to prevent the top from over-browning.
You can also freeze baked portions for up to 2 months. Thaw in the fridge overnight and reheat as directed above.
Variations to Try
Switch up the sausage flavor based on your preference. Italian sausage adds a fennel kick, while turkey sausage makes it a bit lighter.
Try different cheese combinations like pepper jack for heat, Swiss for a milder flavor, or a Mexican blend for taco-inspired vibes. Each variation brings its own unique character.
Add extra veggies like diced bell peppers, sautéed mushrooms, or fresh spinach for more nutrition. Just make sure to cook and drain any moisture-heavy vegetables first.
Frequently Asked Questions
Can I use fresh potatoes instead of frozen hashbrowns?
Yes, you can use fresh potatoes. Grate 4-5 medium russet potatoes, rinse well, and squeeze out all excess moisture using a clean kitchen towel. Fresh potatoes may release more liquid, so make sure they’re very dry before mixing into the casserole.
Can I make this casserole in a slow cooker?
Absolutely! Grease your slow cooker, add all the mixed ingredients, and cook on low for 4-5 hours or high for 2-3 hours until the eggs are set. The texture will be slightly softer than the oven version, but it’s still delicious and convenient.
Why is my casserole watery?
Excess moisture usually comes from not thawing and draining the hashbrowns properly, or not cooking off enough fat from the sausage. Always thaw hashbrowns completely, squeeze out moisture with paper towels, and drain your cooked sausage well before mixing everything.
