In a medium bowl, toss the green beans with oil. Sprinkle with garlic powder, salt, and 1/2 teaspoon minced garlic.
Pour into the air fryer basket and shake to distribute evenly. Air fry for 7-9 minutes, shaking halfway through.
With 1 minute remaining in the cook time, add the remaining 1/2 teaspoon of minced garlic to the green beans. Shake the basket and continue cooking until crispy.
Serve immediately.
