ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

6 cups frozen hashbrowns, thawed
2 cups shredded cheddar cheese
1 cup cooked breakfast sausage, crumbled
8 large eggs
2 cups milk
1/2 cup diced onion
1/2 cup diced bell pepper
1 teaspoon salt
1/2 teaspoon black pepper
1/2 teaspoon garlic powder
2 tablespoons melted butter

directions

I start by preheating the oven to 375°F (190°C) and greasing a baking dish. Then I spread the thawed hashbrowns evenly in the dish and drizzle the melted butter over them.

Next, I layer the cooked sausage, diced onion, and bell pepper on top of the hashbrowns, followed by the shredded cheese.

In a separate bowl, I whisk together the eggs, milk, salt, pepper, and garlic powder until everything is well combined. I pour this mixture evenly over the casserole.

I bake the casserole for about 40–45 minutes, until the eggs are set and the top is golden. After removing it from the oven, I let it rest for a few minutes before slicing and serving.

Servings and timing

I usually get about 6 to 8 servings from this casserole. Preparation takes around 15 minutes, and baking takes about 45 minutes, so the total time is roughly 1 hour.

Variations

I also enjoy adding vegetables like spinach or mushrooms for extra flavor. If I want a bit of heat, I mix in some chopped jalapeños or a pinch of chili flakes. Different cheeses like mozzarella or pepper jack also work well.

storage/reheating

I store leftovers in an airtight container in the refrigerator for up to 3 days. When I want to reheat, I use the microwave for quick portions or place it back in the oven at 350°F (175°C) until warmed through. If I plan ahead, I can also freeze portions and reheat them later.

FAQs

Can I make this casserole ahead of time?

I often prepare everything the night before, cover it, and keep it in the refrigerator. In the morning, I just bake it as directed.

Can I use fresh potatoes instead of frozen hashbrowns?

I can grate fresh potatoes and squeeze out excess moisture before using them as a substitute.

How do I know when the casserole is fully cooked?

I check that the center is set and not jiggly, and a knife inserted in the middle comes out clean.

Can I make this recipe vegetarian?

I simply leave out the sausage and add more vegetables like mushrooms, spinach, or tomatoes.

What type of cheese works best?

I usually use cheddar for its flavor, but I also like experimenting with blends or other cheeses depending on what I have.

Conclusion

This hashbrown breakfast casserole is one of my go-to recipes when I want something comforting, easy, and delicious. I appreciate how flexible it is and how it always turns out satisfying. Whether I am cooking for myself or sharing with others, this dish never disappoints.
