Wash and dry green beans and trim the ends. Add them to a large bowl.
Add oil, salt, pepper and garlic powder. Toss the beans in the seasoning.
Preheat the air fryer at 400°F for 2 minutes. Spread the seasoned beans in the fryer basket. Reduce the temperature to 370°F and cook for 8 minutes, shaking the basket after 6 minutes.
Find already washed and cut green beans at your local grocery store for minimal prep.
Dry the green beans thoroughly after washing so they get nice and crispy when they cook. Too much moisture will result in soggy green beans.
For even cooking, shake the air fryer basket after 6 minutes of cooking. This redistributes the green beans so they cook all the way around.
Adjust the cook time, as needed. If you prefer softer beans, cook for less time. If you prefer a crispier texture, cook longer.
Play around with seasonings to pair this with different foods. Try Italian seasoning to serve it next to pastas, toss with sesame oil to serve next to chicken lo mein, spice it up with cayenne pepper or red pepper flakes, etc. The possibilities are endless.
To roast string beans in the oven, preheat the oven at 425 degrees F. Spread the seasoned beans on an aluminum lined baking sheet. Cook for 12-15 minutes depending on your preferred crispness.
