Bov860BSS vs Bov900BSS Breville manufactures a cutting board that can be placed on top of the oven. It effectively diffuses heat on the top, preventing any cabinet above it from heating up. The cutting board has insulated feet, so it does not become hot. For many years, I've used a Breville Pro oven. This year, I purchased the Air Fryer Pro, mostly for the greater frying capacity.   Both yes and no. If you can locate a dish with a lid that fits, it will.
