There are not a lot of directions with this, but over time, you can experiment with it. I’ve used it only 4 times so far, but have been happy with the results. It’s nice not having to heat my big oven for small dishes. I’ve made cookies, banana bread, and roasted potatoes.  The convection oven is new to me also, but I went online to get ideas on how to adjust the cooking times. That worked great. I think I will use it more and more, and save energy in the process.
