Step 1

Preheat oven to 350 degrees F (175 degrees C). Grease a 9x13-inch dish with cooking spray.

Step 2

Cook sausage in a large skillet, stirring occasionally, until no longer pink, 6 to 8 minutes. Drain fat and transfer to a bowl.

Step 3

Cook and stir hash browns to the same skillet until lightly browned, about 8 minutes. Place hash browns in the baking dish; top with sausage, shredded Cheddar cheese, and green chile peppers.

Step 4

Whisk eggs, milk, salt, pepper, onion powder, and garlic powder in a bowl. Pour over hash brown mixture.

Step 5

Bake uncovered in the preheated oven until bubbly and the top is golden brown, 35 to 40 minutes.
