Recipe Information
Ingredients
- 12 large eggs
- 1 cup whole milk
- 1 teaspoon salt
- 0.5 teaspoon black pepper
- 1 pound breakfast sausage (ground or links, cooked and crumbled)
- 2 cups shredded cheddar cheese
- 1 small onion, diced
- 2 bell peppers, diced (any color)
- 3 cups frozen shredded hash browns (thawed)
- 1 tablespoon butter or cooking spray (for greasing the pan)
- 2 cups optional ingredients (spinach, mushrooms, hot sauce, etc.)
Instructions
Preheat your oven to 375°F (190°C) and lightly grease a 9x13-inch casserole dish with butter or cooking spray.
In a large skillet, cook the breakfast sausage over medium heat until browned and fully cooked. Drain any excess grease and set aside.
In the same skillet, sauté the diced onion and bell peppers until softened, about 5 minutes. If using additional vegetables like mushrooms or spinach, cook them at this stage as well.
Spread the thawed hash browns evenly across the bottom of the greased casserole dish.
Layer the cooked sausage and sautéed vegetables over the hash browns.
In a large mixing bowl, whisk together the eggs, milk, salt, and black pepper until well combined.
Pour the egg mixture evenly over the layers in the casserole dish, ensuring it covers all the ingredients.
Sprinkle the shredded cheddar cheese evenly over the top of the casserole.
Bake in the preheated oven for 45-50 minutes, or until the eggs are set and the top is golden brown.
Remove the casserole from the oven and let it cool for 5-10 minutes before slicing and serving.
Store leftovers in an airtight container in the refrigerator for up to 4 days. To reheat, microwave individual portions until warmed through.
