Ingredients

(Tip: You'll find the full list of ingredients and measurements in the recipe card below.)

2 lb frozen southern-style diced hash browns

1 lb breakfast sausage, browned and drained

15 oz country sausage gravy

2 cups shredded cheddar cheese, divided

Salt, to taste

Black pepper, to taste

Garlic powder, to taste

6 eggs, whisked

2 cups crushed corn flakes

4 tablespoon melted butter

Cooking spray

Directions

I brown the breakfast sausage in a skillet over medium heat until it is fully cooked, then drain any excess grease.

I lightly coat a 9x13-inch oven-safe or smoker-safe baking dish with cooking spray.

I combine the diced hash browns, cooked sausage, country sausage gravy, 1 cup of shredded cheddar cheese, salt, black pepper, and garlic powder in the prepared baking dish, stirring until everything is evenly mixed.

I pour the whisked eggs evenly over the casserole mixture.

I sprinkle the remaining cup of shredded cheddar cheese over the top.

I mix the crushed corn flakes with the melted butter in a small bowl until evenly coated.

I scatter the buttery cornflake mixture evenly across the casserole.

I bake or smoke the casserole at 350°F (175°C) for 1 hour to 1 hour 10 minutes, until the potatoes are tender and the eggs are fully set.

I let the casserole cool for a few minutes before serving it warm with ketchup or hot sauce if I like.

Variations

I like to switch up this casserole depending on what I have available. I sometimes replace the breakfast sausage with cooked bacon, diced ham, or spicy sausage for a different flavor. Pepper Jack cheese adds a little heat, while Monterey Jack or Colby cheese melts beautifully as well. I also enjoy mixing in diced bell peppers, onions, mushrooms, or spinach to add extra vegetables. For a smoky flavor, I occasionally add a dash of smoked paprika or use smoked cheddar cheese.

Storage/Reheating

I store any leftovers in an airtight container in the refrigerator for up to 4 days. If I want to keep the casserole longer, I wrap individual portions tightly and freeze them for up to 3 months. When I'm ready to enjoy it again, I thaw frozen portions overnight in the refrigerator before reheating. I warm individual servings in the microwave for 1 to 2 minutes, or I reheat larger portions in a 350°F oven for about 20 minutes until heated through.

FAQs

Can I prepare this casserole ahead of time?

Yes. I like to assemble the casserole the night before, cover it, refrigerate it, and bake it the following morning for an easy breakfast.

Can I use fresh potatoes instead of frozen hash browns?

Yes. I simply dice fresh potatoes into small pieces and partially cook them before adding them to the casserole so they become tender during baking.

Can I make this casserole without sausage gravy?

Yes. I can replace the gravy with a homemade cheese sauce or simply add a little milk or heavy cream for a lighter texture.

How do I know when the casserole is fully cooked?

I check that the eggs are completely set, the potatoes are tender, and the center reaches a safe temperature before serving.

What can I serve with this breakfast casserole?

I enjoy serving it with fresh fruit, biscuits, toast, orange juice, coffee, or a simple green salad for a complete brunch.

Conclusion

I always enjoy making this Cheesy Hash Brown Breakfast Casserole because it delivers rich, comforting flavors with very little effort. The combination of crispy hash browns, savory sausage, creamy gravy, fluffy eggs, melted cheddar cheese, and crunchy buttery cornflakes creates a breakfast that everyone looks forward to. Whether I make it for a holiday brunch, a weekend breakfast, or meal prep for the week, this casserole never disappoints.
