- Prep Time: 15 minutes
- Cook Time: 45 minutes
- Total Time: 1 hour
- Yield: 8 servings 1x
- Category: Breakfast
- Method: Baking
- Cuisine: American
Ingredients
- 1 pound ground breakfast sausage
- 1 (30 oz) bag frozen hashbrowns, thawed
- 1 1/2 cups shredded cheddar cheese
- 1/2 cup shredded mozzarella cheese
- 6 large eggs
- 1 cup whole milk
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- Optional: green onions or parsley
Instructions
- Preheat the Oven: Preheat your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish. Preheating the oven ensures even cooking. Greasing the baking dish prevents the casserole from sticking. Use a baking dish that is oven-safe and large enough to accommodate the ingredients. Beginner Note: Use a pastry brush to apply a thin layer of grease to the baking dish.
- Cook the Sausage: In a large skillet over medium heat, cook the sausage until browned and fully cooked. Drain excess grease and set aside. Cook the sausage thoroughly to ensure food safety. Draining excess grease prevents the casserole from becoming greasy. Use a skillet that is large enough to accommodate the sausage. Beginner Note: Use a spatula or wooden spoon to break up the sausage as it cooks.
- Assemble the Casserole: Spread the thawed hashbrowns evenly in the prepared baking dish. Sprinkle the cooked sausage over the hashbrowns. Top with 1 cup of shredded cheddar cheese and the mozzarella cheese. Spread the hashbrowns in an even layer to ensure even cooking. Layer the ingredients evenly for a balanced flavor in each serving. Use your hands or a spatula to spread the ingredients. Beginner Note: Distribute the sausage evenly over the hashbrowns.
- Prepare the Egg Mixture: In a medium bowl, whisk together the eggs, milk, garlic powder, onion powder, salt, and black pepper until well combined. Whisk the egg mixture thoroughly to ensure a smooth and even texture. Use a whisk or a fork to mix the ingredients. Beginner Note: Add the milk gradually to the eggs while whisking.
- Combine and Bake: Pour the egg mixture evenly over the casserole. Sprinkle the remaining 1/2 cup of cheddar cheese on top. Bake for 40-45 minutes, or until the eggs are set and the top is golden brown. Pour the egg mixture slowly and evenly to prevent it from overflowing. Bake until the eggs are fully cooked and the cheese is melted and bubbly. Use a toothpick to check if the eggs are set. Insert the toothpick into the center of the casserole; if it comes out clean, the eggs are cooked. Beginner Note: Rotate the baking dish halfway through baking for even browning.
- Serve: Let the casserole cool for 5-10 minutes before slicing. Garnish with chopped green onions or parsley if desired. Letting the casserole cool slightly allows the eggs to set further and makes it easier to slice. Garnish adds a touch of freshness and visual appeal. Use a sharp knife to slice the casserole. Beginner Note: Use a spatula to serve the casserole.
Notes
- Thaw hashbrowns fully.
- Drain sausage well.
- Customize cheese and spices.

Ingredients and Preparation: The Building Blocks of a Hearty Breakfast
This recipe uses simple, readily accessible ingredients, making it a breeze for even the most novice cooks to assemble.
- 1 pound ground breakfast sausage (mild or spicy) – Alternative: You can use Italian sausage, turkey sausage, or even a plant-based sausage alternative. Choose a sausage that fits your dietary needs and flavor preferences. For a leaner option, use turkey sausage. If you prefer a vegetarian version, substitute with a plant-based sausage or a mixture of sautéed vegetables like mushrooms, bell peppers, and onions. Consider using a sausage with added spices for a more robust flavor. Ensure the sausage is thoroughly cooked before adding it to the casserole.
- 1 (30 oz) bag frozen hashbrowns, thawed – Alternative: You can use shredded potatoes, diced potatoes, or even sweet potato hashbrowns. Thawing the hashbrowns is crucial for even cooking. If you have fresh potatoes, you can shred them using a box grater or food processor. Make sure to squeeze out excess moisture from the fresh potatoes using a clean kitchen towel. Consider using seasoned hashbrowns for added flavor.
- 1 1/2 cups shredded cheddar cheese (or your favorite cheese blend) – Alternative: You can use Monterey Jack, Colby Jack, pepper jack, or a combination of cheeses. Choose a cheese that melts well and complements the other flavors. For a dairy-free option, use a vegan cheese alternative. Consider using a sharp cheddar cheese for a more pronounced flavor. Use pre-shredded cheese for convenience, or shred your own cheese for a fresher taste.
- 1/2 cup shredded mozzarella cheese – Alternative: You can use provolone, fontina, or another mild melting cheese. Mozzarella adds a creamy texture and mild flavor. Consider using fresh mozzarella for a softer, more delicate texture.
- 6 large eggs – Alternative: You can use egg whites for a lower-calorie option. Ensure the eggs are fresh for the best results. Use eggs that are at room temperature for even cooking. Consider adding a splash of milk or cream to the eggs for a richer texture.
- 1 cup whole milk – Alternative: You can use 2% milk, almond milk, oat milk, or another milk alternative. Choose a milk that fits your dietary needs and preferences. For a richer flavor, use heavy cream or half-and-half. Consider using a milk alternative that is unsweetened to avoid adding unnecessary sweetness.
- 1/2 teaspoon garlic powder – Alternative: You can use 2-3 cloves of minced fresh garlic. Garlic powder provides a convenient and consistent flavor. Consider roasting the garlic before mincing for a sweeter, milder flavor. Use freshly minced garlic for a more intense flavor.
- 1/2 teaspoon onion powder – Alternative: You can use 1/4 cup of finely chopped onion. Onion powder adds a subtle onion flavor. Consider using sautéed onions for a more robust flavor. Use a combination of onion powder and granulated onion for a more complex flavor.
- 1/2 teaspoon salt – Alternative: You can use sea salt, kosher salt, or any other type of salt you prefer. Adjust the amount of salt to your taste. Consider using flaky sea salt for a textural element.
- 1/4 teaspoon black pepper – Alternative: You can use freshly ground black pepper for a more robust flavor. Consider using a blend of different types of peppercorns for a more complex flavor.
- Optional garnish: chopped green onions or parsley – Alternative: You can use chives, cilantro, or any other fresh herb you prefer. Garnish adds a touch of freshness and visual appeal. Consider using a microgreen mix for a visually appealing garnish.

Beginner Tips and Notes: Your Kitchen Companion
Even simple recipes have a few tricks to make them even better:
- Thaw the Hashbrowns: Thawing the hashbrowns is essential for even cooking. Frozen hashbrowns will release water during baking, which can make the casserole soggy. Place the hashbrowns in the refrigerator overnight to thaw.
- Drain the Sausage: Draining excess grease from the sausage prevents the casserole from becoming greasy. Use a slotted spoon or a colander to drain the sausage.
- Use a Cheese Blend: Using a blend of cheeses adds complexity to the flavor. Choose cheeses that complement each other.
- Don’t Overcook the Eggs: Overcooked eggs will be tough and rubbery. Cook the casserole until the eggs are just set. Use a toothpick to check the doneness of the eggs.
Serving Suggestions: Completing the Breakfast Experience
This Sausage Hashbrown Breakfast Casserole is delicious and satisfying on its own, but you can also enhance it with some complementary sides and pairings.
- Fresh Fruit Salad: A fruit salad adds a refreshing and healthy element to the meal. Use seasonal fruits for the best flavor.
- Toast or English Muffins: Toast or English muffins are perfect for soaking up any leftover egg mixture. Butter the toast or English muffins for added flavor.
- Yogurt with Granola: Yogurt with granola is a light and satisfying side dish. Use plain Greek yogurt or your favorite flavored yogurt.
- Orange Juice or Coffee: Orange juice or coffee are classic breakfast beverages that pair well with the casserole. Use freshly squeezed orange juice for the best flavor.
- Hot Sauce: A dash of hot sauce adds a spicy kick to the casserole. Use your favorite hot sauce.
Storage Tips for Leftovers:
Store leftover casserole in an airtight container in the refrigerator for up to 3 days. Reheat in the microwave or oven until heated through. For best results, reheat the casserole in the oven at 350°F for 15-20 minutes. This will help to restore the crispy texture of the hashbrowns. Reheat the casserole until it is heated through. Avoid reheating the casserole multiple times.
