Step 1: Preheat the Air Fryer

Start by preheating your air fryer to 375°F (190°C). Preheating ensures that your green beans cook evenly and become crispy.

Step 2: Prepare the Green Beans

While the air fryer is preheating, wash the green beans thoroughly and trim the ends - OPTIONAL. You can leave them whole or cut them into bite-sized pieces, depending on your preference. Pat them dry with a kitchen towel to remove any excess moisture.

Step 3: Create the Coating Mixture

In a mixing bowl, combine the neutral oil, panko bread crumbs, grated Parmesan cheese, minced garlic, and a pinch of salt and pepper. Combine the mixture well. 

Step 4: Coat the Green Beans

Toss the green beans in the coating mixture, ensuring they are well coated on all sides.

Step 5: Air Fry the Green Beans

Place the coated green beans in the preheated air fryer basket. You may need to cook them in batches depending on the size of your air fryer.

Cook the green beans at 375°F (190°C) for 8-10 minutes, shaking the basket or tossing the beans halfway through the cooking time. Keep a close eye on them to prevent overcooking; you want them to be crispy and lightly browned.

Step 6: Serve and Enjoy

Once the green beans are golden brown and crispy, remove them from the air fryer basket. Transfer them to a serving platter and serve immediately while they're still hot.
