I find it hard to believe that an oven, let alone a gas oven, instantly heats to the desired temperature with no pre-heat. However, nothing is stopping you from pre-heating and cooking the way you normally do. If you don't pre-heat, just put your food in the oven, set your temp and add an additional 5-10 minutes of cooking time, checking your food for doneness/overcooking during those last minutes.
I absolutely agree with realaud. But the no preheat function refers to the air fryer. Please continue to preheat your oven as you normally would for cooking. We look forward to hearing more from you in the future!
