HOW DO YOU ADJUST COOKING TIMES FOR MULTIPLE DISHES?
In a conventional cooking cycle, heat travels from the bottom to the top of the oven. Make it a best practice to place the largest dishes that require longer cooking times on the bottom rack for direct heat exposure. You will still need to keep an eye on food for crisping and browning and rotate dishes as needed.
If you’re running into overcooked or undercooked food, you may need to calibrate your oven temperature. This can be quickly tested prior to preparing your meals by preheating your oven to 350°F with an oven thermometer centered on the middle rack. If the thermometer reads 15°F higher or lower than it should when preheating is complete, your oven may need calibration.
