Question: do you cook a 20 pound turkey?
Answer: Unsure how long you're supposed to leave the bird in the oven? If you're baking it at 325°F (the lowest temperature the USDA recommends), you'll need to bake a 20-lb turkey in the oven for 4 to 5 hours if it's unstuffed, and 4 ¼ to 5 ¼ hours if it's stuffed.
