Step 3: Once the butter has melted, sprinkle the flour over the sausage, stirring until the mixture is a pasty, thick consistency. Cook for approximately 2 minutes.
Step 4: Raise heat to medium-high and add half the milk, salt, and pepper. Once the milk begins to absorb, add in the remaining milk.
Continue to cook over medium heat, stirring frequently, until the gravy is thick and bubbly.
