Bake biscuits according to package directions (or make your own — see Maggie's Buttermilk Biscuits recipe).

While biscuits bake, cook sausage in a large skillet over medium heat, breaking into crumbles, until fully browned.

Sprinkle flour over the sausage and stir to coat. Cook 1 minute.

Slowly pour in milk, stirring constantly. Cook 5-7 minutes, stirring often, until gravy thickens. Season with salt and plenty of pepper.

Split warm biscuits on plates and smother with sausage gravy. Serve immediately.
