Roast the eggplant
25 minPierce the whole eggplants in a few places with a fork. Roast them in an air fryer set to 200°C / 390°F for 25 minutes, until the skins wrinkle and the flesh softens. If you do not have an air fryer, roast them in an oven preheated to 200°C / 390°F for the same amount of time.
