Equipment

Ingredients

12 ounces breakfast sausage casings removed
¾ bag hash browns frozen diced, thawed
½ cup onion diced
½ cup red bell pepper diced
2 teaspoons kosher salt divided
1 teaspoon black pepper divided
6 ounces sharp Cheddar cheese shredded (about 1½ cups), divided
3 large eggs lightly beaten
1/2 cup whole milk
1 tablespoon flat-leaf parsley chopped

Instructions

Preheat your oven to 350°F. Grease a 9x13-inch baking dish with butter or cooking spray.
Brown the sausage in a large nonstick skillet over medium-high heat, breaking it up as it cooks, about 10 minutes. Once fully cooked, transfer to a plate lined with paper towels to drain.
Add a little oil if needed, and cook the hash browns until they start to crisp, about 6–8 minutes. Stir in the onion and bell pepper, then cook for another 2–3 minutes until the onions soften slightly. Season with 1 tsp of salt and ½ tsp of black pepper.
Stir together the sausage, cooked hash browns, veggies, and 1 cup of the shredded cheese in a large mixing bowl. Spread this mixture evenly in the greased baking dish.
Whisk together the eggs, milk, remaining 1 tsp salt, and ½ tsp pepper in a separate bowl. Pour evenly over the sausage and potato mixture in the dish.
Sprinkle the remaining ½ cup of cheese evenly over the top.
Bake uncovered for 30 minutes or until the center is set and the top is nicely browned.
Let it rest for 5 minutes before topping with parsley and serving warm.
