Wash the green beans and trim off the ends if needed.
Add the green beans to a large bowl. Drizzle the 3 tablespoon olive oil over top. Add the 2 tablespoon freshly grated parmesan cheese (if using, it's optional). Sprinkle the ½ teaspoon garlic powder, ½ teaspoon onion powder, ½ teaspoon ground black pepper and ¼ teaspoon salt.
Toss the green beans together with all the seasonings so that they are evenly coated.
Preheat the air fryer at 350°F for 2 minutes.
Add in the green beans. Use a spatula to scrape along the side of the bowl to get all the oil, parmesan and spices as well. Spread the green beans into an even layer.
Cook for 14 minutes, tossing and shaking the basket with green beans half way through the process. The edges will start to turn golden brown and the parmesan cheese will crispen up during the process.
Recipe Notes:
Check the beans in the last couple of minutes to make sure they’re not overcooking. Every air fryer is different so it might take more time or less time to cook your green beans. It can take a little bit of practice to get used to your specific air fryer temperature and how it works.
Parmesan cheese is optional! I highly recommend using freshly grated parmesan cheese as it adds flavor and these perfect little crispy bits that taste wonderful when served with the veggies!
Refrigerate – These green beans can be stored in an air-tight container or bag in the fridge for up to 3 days. They will naturally gain a bit of sogginess as they’re stored in the fridge, but will still taste great!
To Reheat – Green beans can be reheated in the air fryer at 350°F for 5-10 minutes until they’re heated through and begin to crispen a little on the edges. You can also reheat these in the microwave for 1-2 minutes.
