Sausage Gravy

1 lb. mild breakfast sausage (we're loyal to Jimmy Dean)
1 small onion, diced
1/3 cup flour
3/4 tsp. seasoned salt
Brown sausage over medium heat. After about half the meat is browned, add diced onions. Continue cooking until all the sausage is browned and onions are soft. Sprinkle the flour over the sausage and stir well. Continue stir until no flour is visible and sausage is coated, about one minute. Add enough milk to mostly cover the sausage. Add in seasoned salt and increase the heat to high, stirring constantly. The gravy should come to a boil and thicken quickly. Once it reaches desired consistency, remove from heat. Serve over warm biscuits.
