My old crock pot died and I saved the tall round crock insert to bake/roast in the oven. It can take very high heat. It is excellent to roast the upright chickens (beer can chicken). It's usually easy to find the crock inserts at thrift stores. I have a big oval one I use to bake big casseroles for potlucks. The food stays warm a long time and the crock pot lid fits perfectly. But I don't put the lid in the oven. I cover it with foil if the pot needs to be covered.
