If using Buddig Original Deli Thin Beef, remove it from the packaging and stack the slices. Use a sharp knife or kitchen shears to cut the beef into small squares, approximately ½ inch in size.
Brown The Beef
Heat a large skillet over medium heat. Add the cut beef to the skillet and fry, stirring occasionally, for 1-2 minutes until the beef is warmed and slightly browned. If the beef is very lean, you may need to add a teaspoon of butter or oil to prevent sticking.
Make The Roux
Add 4 Tablespoons of butter and sprinkle 4 Tablespoons of flour over the the beef mixture. Stir gently buththoroughly to combine the flour and butter. The mixture should look like a paste coating the beef.
Add The Milk
Gradually pour in 2 cups of milk, about ½ cup at a time, stirring constantly with a whisk or wooden spoon to prevent lumps. Continue stirring as the mixture heats, scraping the bottom of the skillet to incorporate all the roux into the mik.
Thicken The Gravy
Bring the mixture to a gently simmer over medium heat, stirring frequently. The gravy will begin to thicken after a few minutes. You'll know the gravy is ready when it clings to the back of a spoon, and running your finger through it leaves a trail that holds its shape.
Season and Serve
Taste the gravy and adjust the seasoning with salt and pepper if needed. Serve with warm biscuits or toast.
