Step 1: Prepare the Oven, Pan, and Biscuits - Preheat your oven to 350°F and lightly coat a
9x13 inch baking dish with nonstick cooking spray. While the oven heats, open the biscuits and cut each one into about four to six smaller pieces. I lean toward smaller pieces because thick chunks of dough can stay undercooked in the middle of a creamy casserole. Set the pieces aside while you make the filling.
