Prep Your Vegetables. Before you start air frying, wash and chop your vegetables into uniform pieces. This will ensure that they cook evenly. If you're using denser vegetables like potatoes or carrots, you may want to soak them in cold water for a few minutes before cooking to help them crisp up. Make sure to dry them well before air frying them.

Preheat the Air Fryer. Most air fryers have a preheat setting, so be sure to use it before adding your vegetables. This will help to ensure that they cook evenly and get nice and crispy.

Add a Light Coat of Oil. To help your vegetables crisp up, lightly coat them in oil before adding them to the air fryer. You can use any type of oil that you like, but olive oil or avocado oil work well. Just be sure not to use too much, as this can lead to soggy vegetables.

Cook Your Vegetables. Once your air fryer is preheated, add your vegetables to the basket in a single layer. Close the air fryer and set the timer for the recommended cooking time. Most vegetables will cook in about 10-15 minutes, but denser vegetables like potatoes may take a bit longer.

Enjoy! Once your vegetables are cooked to your liking, remove them from the air fryer and serve immediately. You can season them with your favorite herbs and spices, or enjoy them as is.
