Ingredients
- 1 lb breakfast sausage (mild or spicy)
- 1 tbsp olive oil (if needed)
- 1 small onion, finely chopped
- 3 cups frozen shredded hash browns (thawed)

Step-by-Step Instructions
Preheat the Oven:
Preheat oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
Cook the Sausage:
In a skillet over medium heat, cook the sausage until browned and fully cooked. Remove excess grease if needed. Add chopped onion and sauté until translucent, about 3 minutes. Set aside.
Assemble the Base:
Spread the thawed hash browns evenly across the bottom of the baking dish. Layer the cooked sausage and onion mixture on top, followed by a generous sprinkle of cheddar cheese.
Prepare the Egg Mixture:
In a bowl, whisk together the eggs, milk, garlic powder, salt, and pepper. Pour evenly over the casserole layers.
Bake:
Bake for 40–45 minutes, or until the center is set and the top is golden brown. Let cool slightly before slicing.
Serve:
Garnish with chopped chives or parsley and serve warm. Leftovers reheat beautifully.
