@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.

@merpreb @lioness I cooked a tenderloin roast for Christmas dinner and followed Ina Garten's recipe. It was 500° for about 30 minutes. My son, who cooks a bit, thought it was going to turn to ash but it was perfect! When we were visiting him in February and his future parents-in-law came too, he cooked one also, following the same recipe. Perfect. It is alarming, but dear Ina, knows her stuff.
