Air frying vegetables: what you need to know
Vegetables transform in an air fryer: the rapid airflow removes surface moisture and caramelizes natural sugars, producing edges that are crispy and slightly charred while the interior stays tender. This is the same Maillard reaction you get on a grill or in a very hot oven, but faster and with less oil — typically 1–2 teaspoons per portion is enough. Dense vegetables like carrots, broccoli, and Brussels sprouts need more time than thin or leafy ones. Cut vegetables into similar sizes for even cooking, and toss them with a light coating of oil and seasoning before cooking. Shake the basket halfway through to prevent sticking and ensure even browning.
