Sausage gravy is a white gravy recipe using the same ingredients as a classic country gravy - butter, flour, milk, and seasoning - in addition to sausage. It is a classic southern breakfast recipe generally served over biscuits as biscuits and gravy. My sausage gravy recipe consists of breakfast sausage, butter, flour, maple syrup, milk, steak seasoning, garlic powder, salt and pepper, and red pepper flakes (optional).
