Start by trimming the ends off your fresh green beans and patting them dry thoroughly with a towel. This helps them crisp up better in the air fryer.
Preheat your air fryer to 200°C (390°F). This ensures the beans start crisping immediately once they go in.
In a mixing bowl, toss the green beans with a tablespoon of olive oil, making sure they are evenly coated. The oil helps create that irresistible crispy exterior.
Add a pinch of sea salt and any optional seasonings like garlic powder or chili flakes to the bowl. Toss again to distribute the flavors evenly.
Arrange the beans in a single layer in the air fryer basket. Avoid overcrowding to ensure even crisping and browning.
Air fry the green beans for 8-10 minutes, shaking the basket halfway through. You'll hear a crackling sound and see the edges turn golden brown.
Check the beans—they should be crispy around the edges with a tender interior. If they need more crunch, air fry for another 1-2 minutes.
Transfer the beans to a serving dish and sprinkle with fresh lemon zest for a bright, citrusy finish. Toss gently to distribute.
Serve immediately while they’re hot and crispy. Enjoy the smoky aroma and satisfying crunch in every bite!
