Ingredients
- 1 pound breakfast sausage
- 6 slices bacon, cooked and crumbled
- 1 bag (20 ounces) refrigerated shredded hash browns, thawed
- 8 large eggs
- 1 cup whole milk
- 2 cups shredded cheddar cheese, divided
- 1 cup shredded mozzarella cheese
- 1/2 cup diced onion
- 1/2 cup diced green bell pepper, optional
- 1 teaspoon garlic powder
- 1/2 teaspoon smoked paprika
- 1/2 teaspoon black pepper
- 1/2 teaspoon salt, or to taste
- 2 green onions, sliced, optional for garnish
- Butter or nonstick cooking spray for the baking dish
How to Make Cheesy Bacon Potato Breakfast Casserole
Preheat the oven to 375°F. Grease a 9-by-13-inch baking dish with butter or nonstick cooking spray.
Heat a large skillet over medium heat. Cook the breakfast sausage, breaking it apart with a spoon, until browned and fully cooked. If using onion and bell pepper, add them during the last few minutes of cooking until softened. Drain any excess grease.
Spread the thawed hash browns evenly in the prepared baking dish. Spoon the cooked sausage mixture over the potatoes, then scatter the crumbled bacon on top. Sprinkle with 1 cup of cheddar cheese and the mozzarella.
In a large bowl, whisk together the eggs, milk, garlic powder, smoked paprika, black pepper, and salt. Pour the egg mixture slowly and evenly over the casserole.
Top with the remaining cup of cheddar cheese. Bake uncovered for 45 to 55 minutes, until the center is set and the cheese is melted and golden. A knife inserted near the middle should come out mostly clean.
Let the casserole rest for 10 minutes before slicing. Finish with green onions if desired.
Tips for the Best Casserole
Use thawed hash browns so the casserole bakes evenly and does not release excess moisture. If they are very wet after thawing, gently pat them dry with paper towels.
Cook the sausage completely before assembling the dish. This keeps the casserole flavorful without adding unnecessary grease.
For the best cheesy pull, use a combination of sharp cheddar for flavor and mozzarella for meltiness. Freshly shredded cheese melts more smoothly than pre-shredded cheese.
Do not overbake. Remove the casserole once the eggs are set in the middle; it will continue to firm up while resting.
Easy Variations
For a sausage-only version, leave out the bacon and add an extra 1/2 pound of sausage.
For a bacon and egg casserole, skip the sausage and use 10 slices of bacon instead.
For a spicy breakfast casserole, use hot breakfast sausage, pepper jack cheese, or diced jalapeños.
For extra vegetables, add sautéed mushrooms, spinach, diced tomatoes, or chopped broccoli. Cook watery vegetables first so they do not make the casserole soggy.
For a lighter version, use turkey sausage, reduced-fat cheese, and milk of your choice.
What to Serve with It
This casserole is hearty enough to serve on its own, but it pairs beautifully with fresh fruit, orange slices, a simple green salad, or toasted bread.
For a brunch spread, serve it with cinnamon rolls, muffins, pancakes, coffee, and fresh juice.
Make-Ahead Instructions
Assemble the casserole through the cheese topping, cover tightly, and refrigerate overnight. Bake it the next morning as directed, adding 5 to 10 extra minutes if it is very cold from the refrigerator.
You can also cook the sausage and bacon one day ahead to make assembly even faster.
Storing and Reheating Leftovers
Store leftover casserole in an airtight container in the refrigerator for up to 4 days.
Reheat individual portions in the microwave until hot throughout. For a larger portion, cover the baking dish with foil and warm in a 350°F oven for 15 to 20 minutes.
Can You Freeze Breakfast Casserole?
Yes. Let the baked casserole cool completely, then cut it into portions and place them in freezer-safe containers. Freeze for up to 2 months.
Thaw overnight in the refrigerator before reheating, or microwave individual portions from frozen in short intervals until hot.
Frequently Asked Questions
Can I use diced potatoes instead of hash browns?
Yes. Use about 4 cups of cooked diced potatoes, roasted potatoes, or frozen diced potatoes that have been thawed.
Can I use a different cheese?
Absolutely. Monterey Jack, Colby Jack, pepper jack, Swiss, or gouda all work well in this recipe.
How do I know when it is done?
The center should no longer look wet or jiggle when the dish is gently moved. The eggs should be fully set, and the top should be golden and bubbly.
Can I make this without meat?
Yes. Leave out the sausage and bacon, then add sautéed vegetables such as mushrooms, spinach, peppers, and onions for a satisfying vegetarian version.
