Thanksgiving Crock Pot Recipes Sweet Potatoes This one takes minimal effort, but packs maximum flavor. Wash and dry your sweet potatoes before wrapping them in tinfoil and piling into the crock pot. Cook on high for six hours, and resist the urge to open the lid so the steam doesn’t escape. Serve with butter, brown sugar and mini marshmallows. #crockpotrecipes #sweetpotatoes #potatorecipes #bakedpotato
