For air frying your Cheese and Herb Oven Fries, you would typically cook them at 400°F (200°C). The cooking time can vary based on the thickness of your fries, but generally, they should be ready in about 15-20 minutes. It's a good idea to shake the basket halfway through the cooking time to ensure the fries cook evenly and get a nice, even crispiness. Remember to check the fries towards the end of cooking to ensure they don't overcook and adjust the time as needed for your desired level of crispiness.
