Sausage gravy is a popular breakfast dish that consists of crumbled sausage cooked in a creamy gravy and served over biscuits. However, there are a few other names it goes by, depending on where you are in the world. In the southern United States, it's often called "white gravy," while in the northeast, it's sometimes called "sawmill gravy." Other variations include "red-eye gravy," which is made with coffee, and "ham gravy," which replaces the sausage with ham. Regardless of the name, one thing is for sure: sausage gravy is a delicious and satisfying breakfast dish that's perfect for a lazy weekend morning.
