Easy Steps

Preheat your air fryer to 375°F (190°C) for about 5 minutes.

In a large bowl, toss the trimmed green beans with olive oil, salt, pepper, and garlic powder. Make sure the green beans are evenly coated with the seasonings and oil.

Place the seasoned green beans in a single layer in the air fryer basket. This allows for better air circulation and even cooking.

Cook the green beans in the preheated air fryer for approximately 8 minutes, tossing them once at the halfway point. Keep an eye on them; cooking times may vary based on the specific air fryer model and the thickness of the beans. They should become lightly charred, blistered, and tender.

Once the green beans are done, remove them from the air fryer basket. Sprinkle the lemon zest over the cooked green beans while they are still hot.
