  • Total Time: 1 hour 10 minutes
  • Yield: 8 servings

Ingredients

Main Ingredients

  • 4 cups frozen hashbrowns or diced potatoes, thawed
  • ½ pound breakfast sausage
  • 6 slices bacon, cooked and crumbled
  • 8 large eggs
  • 1 cup milk
  • 2 cups shredded cheddar cheese
  • ½ cup shredded Monterey Jack cheese
  • ½ cup diced bell peppers
  • ¼ cup diced onion
  • ½ teaspoon salt
  • ½ teaspoon black pepper
  • ½ teaspoon garlic powder
  • ½ teaspoon paprika
  • 1 tablespoon butter or cooking spray (for greasing the dish)

Instructions

  1. Preheat and Prepare: Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish thoroughly with butter or cooking spray to prevent sticking.
  2. Cook Sausage: In a medium skillet over medium heat, cook the breakfast sausage until it is browned and fully cooked through. Drain any excess grease to keep the casserole from being too oily.
  3. Layer Hashbrowns: Spread the thawed hashbrowns evenly at the bottom of the prepared baking dish, creating a solid base layer for the casserole.
  4. Add Meat and Vegetables: Distribute the cooked sausage, crumbled bacon, diced bell peppers, and onions evenly over the hashbrowns for a balanced mix of flavors and textures.
  5. Add Cheese: Sprinkle shredded cheddar and Monterey Jack cheese evenly over the top of the layered ingredients to create a rich, cheesy crust.
  6. Mix Egg Mixture: In a large bowl, whisk together the eggs, milk, salt, black pepper, garlic powder, and paprika until fully combined and smooth.
  7. Pour Egg Mixture: Carefully pour the egg mixture evenly over the casserole layers, ensuring it seeps through the ingredients for a cohesive bake.
  8. Bake: Place the casserole in the preheated oven and bake uncovered for 45 to 50 minutes, or until the center is fully set, and the top is golden brown and bubbly.
  9. Rest and Serve: Remove the casserole from the oven and let it rest for 5 to 10 minutes before slicing. This helps it firm up for easier serving and better flavor.

Notes

  • Add sliced jalapeños to the mix for a spicy kick.
  • Feel free to swap out meats or use just one type of protein if preferred.
  • This casserole can be assembled the night before and baked fresh in the morning for convenience.
  • Leftovers store well in the refrigerator for up to 4 days and reheat nicely.
