@lioness I only use an oven temperature over 350 F for roasting veges and certain recipes that call for it. I like it for veges because it goes quickly and if your veges are cut thin enough they get done without getting tough and chewy. The denser veges I cook 20 min, but less dense like asparagus, peppers, onions, celery, etc. I only cook for 10-15 minutes. It was scary the first time but I am getting used to it.
