Preheat oven to 350. Prepare a 13 "x 9" pan with cooking spray; set aside. In a mixing bowl, combine hash browns, bacon crumbs, half the cheese, and one teaspoon salt. Mix well. Spoon into prepared pan. In another mixing bowl, combine eggs, milk, remaining salt, and black pepper. Mix until smooth. Pour evenly over the hash brown mixture. Top with the remaining cheese. Bake, uncovered, for 50 minutes, or until eg mixture is cooked through.
