Venison Roast in a Bag

Preheat oven to 325 degrees. Place flour in oven bag and shake to coat sides of bag. Place bag in a 13x9 inch baking pan. Add gravy and water to bag and squeeze to blend. Add venison roast, salt, pepper, bay leaf and mushrooms. Place carrots, onions and potatoes around roast. Seal bag and cut 4 to 6 small slits in the top to allow steam to escape. Bake 2 to 2 1/2 hours until venison is cooked through and tender. Remove bag from oven and let stand 5 minutes before serving.
