Ingredients

• 10 large eggs
• 1 cup whole milk
• 1 pound breakfast sausage
• 4 medium russet potatoes
• 1 large red bell pepper
• 1 large green bell pepper
• 1 medium yellow onion
• 2 cups shredded cheddar cheese
• 1 cup shredded mozzarella cheese
• 1 teaspoon garlic powder
• 1 teaspoon paprika
• 1 teaspoon salt
• 0.5 teaspoon black pepper
• 1 tablespoon unsalted butter
• 1 sufficient cooking spray

Directions

Step 1

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

Step 2

Peel the russet potatoes and dice them into small cubes. Parboil them in boiling water for 5 minutes, then drain and set aside.

Step 3

In a large skillet, cook the breakfast sausage over medium heat until browned and fully cooked. Break it up into crumbles with a spoon or spatula. Drain any excess grease and set aside.

Step 4

Dice the red bell pepper, green bell pepper, and yellow onion into small pieces.

Step 5

In the same skillet, melt the unsalted butter over medium heat. Add the diced bell peppers and onion, cooking until softened, about 5 minutes. Remove from heat and set aside.

Step 6

In a large mixing bowl, whisk together the eggs, whole milk, garlic powder, paprika, salt, and black pepper.

Step 7

Layer the parboiled potatoes evenly across the bottom of the prepared baking dish.

Step 8

Spread the cooked sausage crumbles evenly over the potatoes.

Step 9

Top the sausage with the sautéed vegetables and an even layer of shredded cheddar cheese and shredded mozzarella cheese.

Step 10

Pour the egg mixture over the top of the ingredients, making sure it spreads evenly throughout the dish.

Step 11

Bake the casserole in the preheated oven for 40-45 minutes, or until the eggs are set and the top is golden brown.

Step 12

Let the casserole rest for 5 minutes before slicing and serving.
