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.)

Directions

Step 1

Preheat your oven to 375°F (190°C) and lightly grease a 9x13-inch casserole dish with butter or cooking spray.

Step 2

In a large skillet, cook the breakfast sausage over medium heat until browned and fully cooked. Drain any excess grease and set aside.

Step 3

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.

Step 4

Spread the thawed hash browns evenly across the bottom of the greased casserole dish.

Step 5

Layer the cooked sausage and sautéed vegetables over the hash browns.

Step 6

In a large mixing bowl, whisk together the eggs, milk, salt, and black pepper until well combined.

Step 7

Pour the egg mixture evenly over the layers in the casserole dish, ensuring it covers all the ingredients.

Step 8

Sprinkle the shredded cheddar cheese evenly over the top of the casserole.

Step 9

Bake in the preheated oven for 45-50 minutes, or until the eggs are set and the top is golden brown.

Step 10

Remove the casserole from the oven and let it cool for 5-10 minutes before slicing and serving.

Step 11

Store leftovers in an airtight container in the refrigerator for up to 4 days. To reheat, microwave individual portions until warmed through.
