It doesn't strike me as a very difficult thing to do. If it fits in one of your panniers, stick it in and take it that way. If not, strap it down securely to whatever cargo rack you have. One of those wide "porteur" style front racks would probably work best, but with adequate use of tie downs a rear rack would probably also be fine.
You could also use a trailer if you wanted, but it seems a bit excessive unless this is a truly giant crock pot.
