I make biscuits and gravy at least a couple times a month on the weekends. Here’s my really easy recipe that everyone seems to really like:
Brown 1lb ground breakfast sausage in a cast iron skillet breaking it up like you would ground beef. When the sausage is brown season with about 1 TBS ground dried sage. Slowly stir in 1/4 cup AP flour (stir in a little at a time so that it’s soaking up the grease and coating the sausage). Slowly stir in 2 1/2 cups of whole milk. Simmer, stirring constantly until it thickens.
That’s it, 4 ingredients and it takes maybe 15-20 minutes total. I buy the pre-made biscuits at the store because scratch made biscuits would be too much hassle.
