While air fryer preheats, trim and wash green beans. Add to a large bowl, then drizzle with olive oil. Add a sprinkling of salt and pepper. Toss to combine.
Add to air fryer basket and cook for 8-10 minutes at 380 degrees F, shaking halfway through cooking.
Remove from air fryer basket and serve as desired.
Notes
Cook times may vary depending on your air fryer.
Start checking around the 8 minute mark for doneness, and leave in longer if needed. Green beans should be roasted, but not burned.
