Wash and trim the ends off your green beans. Thoroughly dry the green beans with paper towel.
In a medium bowl add your green beans and drizzle the oil over top. Sprinkle the salt and pepper over and mix well until the green beans are coated completely.
Add 1/2 the green beans to the air fryer basket in a single layer. Cook for 5 minutes, then shake the basket and stir, then keep cooking for another 3-5 minutes until they are tender.
Serve with a slice of lemon to squeeze over top and enjoy!
Notes
To add a little extra flavor you can always add 1/4 teaspoon of garlic powder when preparing these.
