How long do you cook a 13 x 9 pan of frozen cooked cornbread dressing?

To reheat a 13 x 9 pan of frozen cooked cornbread dressing, preheat your oven to 350°F (175°C) and cover the pan with aluminum foil. Bake for about 45 minutes to 1 hour, or until it is heated through and reaches an internal temperature of 165°F (74°C). You can remove the foil for the last 10-15 minutes to crisp the top if desired. Always check for even heating before serving.
