What temperature does stuffing have to be?

165°F.
Also, you’ll need a food thermometer for determining when stuffing is safely cooked to a minimum internal temperature of 165°F. Use this temperature as a guide, whether you serve stuffing separately in a casserole dish or stuffed into poultry or meat.

How do you know when your stuffing is done?

Any extra stuffing gets cooked alongside the bird in a casserole dish. Cook the stuffing in the bird to 160° to 165°F. Check it with an instant-read thermometer inserted all the way into the center of the stuffing.
