Cheesy Hash Brown & Sausage Casserole Recipe

Ingredients

1 pound breakfast sausage (pork or turkey)
1 bag (20 ounces) frozen shredded hash browns, thawed
1 ½ cups shredded cheddar cheese
½ cup shredded mozzarella cheese
6 large eggs
1 cup whole milk
½ teaspoon garlic powder
½ teaspoon onion powder
½ teaspoon salt
¼ teaspoon black pepper
1 tablespoon butter (for greasing the baking dish)
2 green onions, sliced (optional, for garnish)

Instructions

Preheat the oven to 375°F and grease a 9×13-inch baking dish with butter.

In a large skillet over medium heat, cook the sausage until browned and fully cooked, breaking it up into crumbles as it cooks. Drain any excess grease.

In a large mixing bowl, whisk together the eggs, milk, garlic powder, onion powder, salt, and pepper.

Spread the thawed hash browns evenly in the greased baking dish. Sprinkle the cooked sausage over the top, followed by the shredded cheddar and mozzarella cheeses.

Pour the egg mixture evenly over the entire casserole, ensuring it soaks into the layers.

Bake uncovered for 35-40 minutes, or until the center is set and the top is golden brown.

Let the casserole cool for a few minutes before slicing. Garnish with sliced green onions if desired, then serve warm.
