Question: how long to cook a chicken breast in a convection oven?
Answer: If you cook at a high temperature (400-450°F), cooking time will only be 15-20 minutes. At a lower temp (325-375°F), 25-30 minutes is a good guideline. Obviously, this depends on the thickness of your poultry. I use either convection roast or convection bake when cooking chicken breasts.
