You can freeze Buffalo Chicken dip! I suggest that you mix all of the ingredients together and then freeze, uncooked, in a ziplock bag or other air-tight container. When you want to put the dip in the crockpot, let it thaw overnight in the fridge first. Be sure to stir the dip as it’s cooking. Cream cheese can try to separate after it’s been frozen, but stirring should help you avoid that.
