Stir together everything but the butter in a 6 quart slow cooker that you've greased.
Dot with the butter.
Cook, covered, on LOW for 4 hours or until cooked through and set.
Fluff with fork if needed.
CAN THIS CORNBREAD DRESSING BE MADE AHEAD OF TIME?
Yep. You can assemble it about a day ahead and store it in the refrigerator, tightly covered. Since you’re starting from cold I’d give the slow cooker an extra hour or two.
CAN SOUTHERN CORNBREAD DRESSING BE FROZEN?
It freezes relatively well. It’s so easy I wouldn’t make it ahead and freeze it but if you have leftovers you could freeze and then serve it with chicken and gravy later on. The texture changes just a touch. To freeze, pack into freezer containers and freeze for up to 3 months. Thaw in the fridge overnight before using.
