The Furrion oven will work pretty good, but you can expect to burn the bottom of anything you put in it. So, use a lower temperature, or put a flat cookie dish under the item you are baking. Also, set the food item as high as possible in the oven.
Next, about every 10 minutes, open the oven door and rotate you food item 180 degrees. This keep the cooking temperature a little more consistent throughout the entire food item.
Some folks will put a pizza stone in the oven, but for the life of me I have no idea how they do that. My oven simply does not have the space for one and still have room for the what's being baked.
Another tip.... the numbers on the knob mean absolutely nothing. You should get an oven thermometer and place it in the oven and get the actual temperature on different tick-marks on the dial. They can off as much as 100 degrees. But, the temperature at the top of the oven will be different than an item at the bottom. So, even that is hard to figure out.
So, we learned to set the oven at a very low setting for everything we do, rotate the pan every 10 minutes, and set the items on the highest shelf setting that still allow the pan to be placed in the oven.
Another tip: in order to begin to learn the quirks with your oven, pick up a roll of Pillsbury bisquits or rolls and bake them one at a time, adjusting your technique, temperature, and shelf setting. When you get the biscuits right, that setting will work well for just about everything .... except baked potatoes, and those we simply put on the highest the knob will turn, and rotate the potatoes ever 10 minutes until they are done.
My wife now spits out some fantastic foods from our oven, all kinds of pastries and baked dishes. And we haven't had anything burn in the oven or have a hard bottom for over 6 years now. (It took about a year to learn the quirks of that oven).... so be patient.... that's why the biscuits are the way to start! Cheap biscuits at that... you will burn them initially.
