In a skillet over medium heat, cook the breakfast sausage until browned and crumbly, about 5-7 minutes.

Sprinkle the flour over the cooked sausage and stir well to combine.

Cook the flour mixture for about 1-2 minutes, stirring constantly.

Slowly whisk in the buttermilk, mixing thoroughly until smooth.

Bring the mixture to a gentle simmer, stirring frequently.

Add salt and pepper to taste, stirring well.

If the gravy is too thick, whisk in a little more buttermilk until you reach the desired consistency.

Remove the skillet from heat and serve warm over biscuits or your dish of choice.
