Start by preheating your air fryer at 375 degrees.
White the air fryer is preheating, wash and then snap the ends off of your green beans. Toss them in a bowl with the olive oil, salt, pepper, and garlic powder.
Transfer to the air fryer and fry at 375 degrees for 8-10 minutes, removing 1-2 times during cooking to toss.
Allow the beans to cool slightly before serving.
Nutrition information is approximate.You can adjust the cook time to ensure your green beans are cooked to your preferences. If you like them a little less cooked/crispy, only cook for about 8 minutes. If you prefer them to be a little crispier, cook for closer to 10 minutes. Exact time and level of crispiness will depend on your air fryer.
