Step 1

Preheat oven to 450 degrees F. Spray a 9 x 13″ baking dish liberally with cooking spray.

Step 2

Pour a shallow layer of hashbrown potatoes over the bottom of the pan, about an inch deep. Bake in preheated oven for 20 minutes.

Step 3

Meanwhile, heat olive oil in a large skillet over medium-high heat. Saute bell pepper, jalapeño, and 1/2 tsp. salt for 5 minutes. Add onion and sausage. Continue to cook, stirring often, until sausage is cooked through.

Step 4

When potatoes have cooked for 20 minutes, carefully remove pan from the oven. Spread sausage mixture over the potatoes.

Step 5

Whisk together eggs, milk, 1/2 tsp. salt, garlic powder, and pepper. Pour eggs evenly over the casserole. Spread cheese over the top.

Step 6

Reduce oven temperature to 350 degrees F. Return casserole to the oven, and bake 20-25 minutes longer, or until eggs are set in the center. Garnish with cilantro if desired.
