Place a large skillet over medium heat. Add the breakfast sausage. Break it into small pieces while cooking. Stir often until browned and fully cooked. This usually takes about 8 minutes. Keep some grease in the skillet for flavor.

Add butter to the cooked sausage. Stir gently until melted completely. The butter gives extra richness and smooth texture. This step also helps the flour blend evenly into the sausage mixture.

Sprinkle flour over the sausage mixture slowly. Stir continuously for about 2 minutes. The flour should coat every sausage piece well. Cooking the flour removes the raw taste and helps thicken the gravy perfectly.

Slowly pour milk into the skillet while whisking constantly. This prevents lumps from forming. Keep stirring gently as the gravy starts thickening. The mixture will become creamy and smooth after several minutes.

Add salt, black pepper, garlic powder, and red pepper flakes. Stir everything well. Taste the gravy carefully. Adjust seasoning if needed. The black pepper gives the classic Southern gravy flavor everyone loves.

Reduce the heat to low. Let the gravy simmer gently for 5 minutes. Stir often to avoid sticking. The gravy will become thicker and richer during this time while keeping a creamy texture.

Spoon the hot sausage gravy over warm biscuits. Serve immediately while fresh and creamy. Add extra black pepper on top if desired. This dish tastes best warm straight from the skillet.
