Begin by removing your package of frozen green beans from the freezer. Cut it open and pour the frozen green beans into a mixing bowl.
Drizzle with olive oil, and season with your garlic salt. Toss until the green beans are coated in both olive oil and garlic salt.
Preheat your air fryer to 375°F (190°C).
Once coated, pour your green bean mixture into the air fryer basket. Replace the basket into your preheated air fryer and cook for approximately 5 to 6 minutes.
Then open the air fryer basket and toss the beans, replacing the basket. Continue cooking for another 2 to 4 minutes until the beans are done to your liking.
Once done, remove from your air fryer basket, serve, and enjoy!
