The easiest way to freeze this chili con queso will be to place it in a Ziplock bag or freezable airtight container once it has cooled completely. Place the bag, flat, in the freezer. It should keep for up to 3 months if stored properly. To reheat, allow to thaw in the fridge and then heat in the microwave. You may need to add a little milk when reheating to keep the consistency smooth.u003cbr/u003e
