Bread machines come with their own “built-in”, non-stick bread pans. The pan will have a paddle in the bottom, and be detachable from the machine.
You don’t grease bread pans in bread machines; as the bread pans double as a “mixing bowl”, anything you coat them with will just get caught up in the mixing. Never, ever insert a knife or anything metal into a bread machine’s bread pan. If the bread pan’s non-stick surface gets damaged or scratched, you have to order a new one. Some services will resurface them (and other non-stick pans), but they are very hard to find.
Always use oven mitts to remove them from the bread machine when the baking cycle has finished. These pans are not dishwasher safe, but rarely need anything more than a rinse.
After a period of time, the pans may start to leak or develop other problems. Replacement ones can be ordered from the maker of the bread machine. Some makers will replace the pans for free if problems with the pan developed within the machine’s warranty period.
