- 1 red bell pepper, diced (optional, for color and sweetness)
- 1 pound frozen shredded hash browns, thawed and patted dry (or 6 cups day-old bread cubes)
- 2 cups shredded sharp cheddar cheese (pre-shredded saves time; mix with Monterey Jack for extra melt)
- 8 large eggs
- 1.5 cups milk (whole or 2%; use 1 cup milk + 0.5 cup half-and-half for extra richness)
- 1/2 cup sour cream (optional, for a softer custard)
- 1 teaspoon kosher salt
- 1/2 teaspoon black pepper
- 1/2 teaspoon garlic powder
- 1/2 teaspoon dry mustard powder
- 1/4 teaspoon smoked paprika or chili powder
- 2 tablespoons unsalted butter, melted, for the pan
- 2 tablespoons sliced scallions or chives, for garnish
- Hot sauce, for serving
Pantry shortcuts and swaps:
- Use pre-cooked sausage crumbles to skip browning.

- Go with refrigerated hash browns if you forgot to thaw frozen ones.

Quick Tips & substitutions
- Pat the hash browns dry so the casserole bakes up fluffy, not watery.
- Drain sausage well and blot with a paper towel to remove extra grease.
- Shred some cheese fresh if you can; it melts smoother than all pre-shredded.
- Mix half cheddar, half pepper jack for a little kick.
- Swap bread cubes for hash browns if you like a strata-style texture.
- Stir in 1 cup cottage cheese for extra protein and creaminess.
- Assemble the night before, cover, and chill; bake straight from the fridge, adding 5 to 10 minutes.
- Let it rest 10 minutes after baking so slices hold their shape.
- Check doneness with a thermometer; the center should hit 165°F.
- For lighter fare, use turkey sausage and low-fat milk.
How to Make Cheesy Sausage Breakfast Casserole
Prep: 15 minutes | Cook: 40 minutes | Total: 55 minutes
- Heat the oven to 350°F. Grease a 9×13 baking dish with melted butter.
- Brown the sausage in a skillet over medium heat, breaking it into crumbles. Add onion and bell pepper, and cook until tender, about 4 to 5 minutes. Drain well.
- Spread hash browns in the baking dish in an even layer. Scatter the sausage mixture over the top. Sprinkle 1.5 cups of the cheese over everything.
- Whisk eggs, milk, sour cream, salt, pepper, garlic powder, mustard powder, and smoked paprika in a large bowl until smooth.
- Pour the egg mixture evenly over the sausage and hash browns. Tap the dish on the counter to settle the custard into the gaps.
- Cover loosely with foil and bake for 25 minutes. Remove foil, sprinkle the remaining 1/2 cup cheese on top, and bake 15 minutes more, until the center feels set and the edges look golden.
- Let the casserole rest for 10 minutes. Garnish with scallions, slice into squares, and serve with hot sauce.
Variations
- Gluten-free: Use certified gluten-free hash browns and sausage.
- Low carb: Swap hash browns for 3 cups riced cauliflower and reduce milk to 1 cup.
- Veggie-loaded: Add 1 cup sautéed mushrooms and 1 cup spinach, squeezed dry.
- Tex-Mex: Use pepper jack, add a small can of diced green chiles, and top with pico.
- Greek-ish: Use feta, sautéed spinach, red onion, and a pinch of oregano.
- Bacon swap: Use 8 slices cooked, crumbled bacon in place of sausage or mix half and half.
- Heat lovers: Add crushed red pepper or a drizzle of chili crisp before serving.
- Bread version: Replace hash browns with 6 cups day-old bread cubes and reduce hash browns to zero.
Ways to Serve Cheesy Sausage Breakfast Casserole
- Pair with a simple fruit salad and yogurt.
- Add a green side like arugula with lemon vinaigrette for brightness.
- Offer toppings: salsa, avocado slices, hot sauce, or a dollop of sour cream.
- Serve with warm biscuits or toast soldiers for dipping.
- Pour fresh coffee and set out orange juice for an easy brunch spread.
Storage
Cool leftovers to room temp, then cover and refrigerate for up to 4 days. Reheat slices in a 300°F oven for 10 to 12 minutes or microwave in 30-second bursts until hot. Freeze tightly wrapped squares for up to 2 months; thaw overnight in the fridge and reheat as above. If the top needs crisping, give it 1 to 2 minutes under the broiler and keep an eye on it.
