Now add the green beans into a large bowl and mix it with 1 Tbsp avocado oil, 1/2 tsp garlic powder, 1/8 tsp black pepper, and 1/2 tsp kosher salt (add more as needed).
Once everything is well combined, transfer the green beans into the air fryer basket and air-fryer for about 8-10 minutes (give it a quick shake halfway through). Serve warm.
Notes
Dry the green beans- Oil doesn't adhere to wet green beans so dry them off after washing so the oil will stick, and the seasonings, too.
Trim the ends- The ends are tough and fibrous, so it's best to chop them off so these Air Fryer Green Beans have the best texture.
Thoroughly coat with oil- The oil helps them get that delicious crispness on the outside. Coating them well with oil will ensure they have great texture and are well-seasoned.
Don't overfill the basket- Because air fryers work by circulating hot air quickly, overfilling the basket will cause some green beans to be undercooked or mushy.
