How To Bake Thaw Biscuits overnight in the fridge. Preheat oven to 400 degrees. Prepare filling by mixing turkey, mashed potatoes, gravy, cranberry sauce and green beans in a mixing bowl. Flatten out a biscuit using your hands or a rolling pin into a 4-5 inch circle and place 1 tablespoon of filling in the center of the dough. Using your fingers, bring all edges together and pinch close until sealed. Place on a lined baking sheet seam side down. Bake for 20 minutes or until golden brown. Enjoy!
