Ingredients
Here’s what you’ll need to make a delicious and satisfying hashbrown breakfast casserole:
- 1 bag (about 20 oz) frozen hashbrowns: The base of the casserole, frozen hashbrowns offer the perfect balance of crispy and tender texture once baked. You can use shredded or diced hashbrowns, depending on your preference.
- 1 lb breakfast sausage: A key component that adds savory flavor to the casserole. You can use regular or mild sausage, or swap it for turkey sausage or any other protein you prefer.
- 1/2 cup diced onion: Adds flavor and depth to the dish. You can use yellow, white, or red onion for slightly different tastes.
- 1 1/2 cups shredded cheddar cheese: The melty, gooey cheese is a must in this casserole. Cheddar works well, but feel free to experiment with mozzarella, pepper jack, or any other cheese you like.
- 6 large eggs: These hold everything together and provide the structure needed for the casserole. Eggs also add protein and make the casserole rich and creamy.
- 1 cup milk: To create a smooth texture, milk helps blend the eggs and cheese together. You can use any type of milk—dairy or non-dairy, depending on your preference.
- 1 teaspoon garlic powder: Adds a savory, aromatic flavor that complements the rest of the ingredients.
- 1/2 teaspoon salt: Enhances the flavors in the casserole.
- 1/4 teaspoon black pepper: A pinch of pepper brings balance and mild heat to the dish.
- Optional toppings: Fresh herbs like parsley or chives, or even hot sauce, if you like a little kick.
How To Make Hashbrown Breakfast Casserole

Making hashbrown breakfast casserole is simple and straightforward. Follow these easy steps, and you’ll have a warm, flavorful casserole ready to serve:
- Preheat the oven: Start by preheating your oven to 375°F (190°C). This ensures that the casserole will cook evenly and turn golden brown.
- Cook the sausage: In a large skillet over medium heat, cook the breakfast sausage, breaking it apart with a spoon as it cooks. Once browned and fully cooked (about 5-7 minutes), remove from the heat and set aside.
- Sauté the onion: In the same skillet, add the diced onion and cook until soft and translucent, about 3-4 minutes. This brings out the sweetness of the onion and adds extra flavor to the casserole.
- Prepare the casserole base: In a large bowl, whisk together the eggs, milk, garlic powder, salt, and black pepper. Add the cooked sausage and onions to the bowl, followed by the frozen hashbrowns. Stir everything together until well combined.
- Assemble the casserole: Grease a 9×13-inch casserole dish with cooking spray or butter. Pour the hashbrown mixture into the dish, spreading it evenly. Top with the shredded cheddar cheese.
- Bake: Place the casserole in the preheated oven and bake for 35-40 minutes, or until the eggs are fully set, and the top is golden brown and bubbly. You can check doneness by inserting a knife into the center; if it comes out clean, the casserole is ready.
- Cool and serve: Let the casserole cool for a few minutes before slicing and serving. This helps it set up and makes it easier to cut into neat squares.
Pro Tips
Here are some pro tips to make your hashbrown breakfast casserole even better:
- Make it ahead: You can assemble the casserole the night before and refrigerate it overnight. In the morning, simply pop it in the oven for a quick and easy breakfast.
- Customize the protein: If you’re not a fan of sausage, you can substitute it with bacon, ham, or even crumbled breakfast sausage patties. For a vegetarian option, sauté mushrooms, peppers, and spinach for a veggie-packed casserole.
- Add more veggies: Want to make your casserole even healthier? Add vegetables like bell peppers, spinach, or tomatoes to the mixture. Sauté them with the onions before adding them to the casserole for extra flavor.
- Try different cheeses: While cheddar is classic, you can experiment with different cheese combinations. Pepper jack adds a bit of spice, while mozzarella makes it extra gooey and creamy.
- Adjust the seasonings: Don’t be afraid to add more spices if you like. A pinch of paprika, cumin, or even a dash of hot sauce can enhance the flavor of the casserole.
How To Serve
Hashbrown breakfast casserole is delicious on its own, but here are a few ways to serve it for an even more satisfying meal:
- Top with fresh herbs: Sprinkle fresh parsley, chives, or green onions over the top to add a pop of color and freshness to the casserole.
- Serve with salsa or hot sauce: If you like a bit of spice, serve the casserole with a side of salsa or drizzle hot sauce over the top.
- Pair with fruit: Serve the casserole with a side of fresh fruit, like orange slices, berries, or a fruit salad. The sweetness of the fruit balances out the savory casserole.
- Pair with a side salad: For a lighter meal, serve the casserole with a side of mixed greens or a simple salad with your favorite dressing.

- In the freezer: You can freeze the casserole before baking or after it’s baked. To freeze before baking, cover the assembled casserole tightly with foil and store it in the freezer for up to 3 months. When you’re ready to bake, let it thaw in the fridge overnight and bake as usual.
