Step 1: Heat the Oven and Prepare the Dish - Start by heating your oven to 375°F. Lightly grease a
9x13 inch baking dish so the creamy filling does not cling stubbornly to the sides later. I like getting the oven and pan ready first because once the beef mixture and biscuit dough are assembled, you can move straight into baking without stopping in the middle of the process.
