In a large skillet, brown the sausage. Do not drain fat.
Add butter.
Once the butter is melted, sprinkle the flour over the sausage, stirring until the mixture is a pasty, thick consistency. Cook for approximately 2 minutes.
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.
Serve immediately over your favorite biscuits.
Notes
You won't need less milk, but you may want additional milk to get the desired consistency before serving.
Be sure you are using breakfast pork sausage, not Italian sausage.
Don't save this recipe for breakfast only. Breakfast at dinnertime is a delicious treat!
