my Stuffing is already made, How long should i put it in the oven for to just warm it up, and at what temp.?
Are you channeling your best self with this comment? (If you're not sure, check out our Code of Conduct.)
At 350 or so for about 30 minutes covered with foil and then pour turkey drippings over it (or a little butter if no drippings available) and then crisp it up uncovered for another 20-30 minutes depending on the surface size of your dish.
Agree with pewins but I would let it sit at room temp for about 1/2 hour before heating.
