Sausage and potato casserole

1 pound bulk breakfast sausage
2 tablespoons all purpose flour
1 1/2 cups milk

1 1-pound package frozen shredded hash brown potatoes
2 green onions, finely chopped
1 1/4 cups grated sharp cheddar cheese

Preheat oven to 350°F. Butter 8x8x2-inch glass baking dish. Cook sausage in heavy large skillet over medium-high heat until brown, breaking into small pieces with back of spoon, about 5 minutes.
Mix in flour, then milk. Cook until mixture thickens and comes to boil, stirring occasionally, about 5 minutes.

Arrange potatoes in prepared dish. Top with green onions, 1 cup cheese, sausage mixture and remaining 1/4 cup cheese.

Bake casserole until potatoes are tender, about 45 minutes.
