Instructions

Cook the Sausage: Preheat oven to 350°F. Lightly grease a 13×9-inch baking dish with cooking spray. In a large skillet over medium-high heat, cook sausage until browned, about 7 minutes. Transfer to a paper towel-lined plate.
Cook the Bell Pepper: In the same skillet, sauté bell pepper over medium heat for 3–4 minutes until softened. Add to the plate with sausage.
Make the Egg Mixture: In a large bowl, whisk together eggs, half-and-half, onion powder, 1 teaspoon garlic salt, and 1/2 teaspoon black pepper. Stir in the sausage, bell pepper, Cheddar, and pepper Jack cheeses.
Layer the Hash Browns: In the prepared baking dish, toss hash browns with the remaining garlic salt and black pepper. Spread evenly across the bottom.
Combine: Pour the egg mixture over the hash browns, pressing down slightly to submerge everything.
Bake: Bake uncovered for 45 minutes, or until eggs are set and hash browns are golden brown. Let rest for 15–20 minutes before serving.
Garnish: Sprinkle with scallions before serving.

Notes

Assemble the casserole the night before, cover, and refrigerate for an easy bake in the morning.

Swap the sausage for bacon, turkey sausage, or ham for variety.

Add jalapeños or spicy sausage for a kick of heat.
