Trim the Green Beans: Start by trimming the ends off the fresh green beans, removing any tough or fibrous parts. If you prefer, you can also cut them into smaller, bite-sized pieces.
Blanch the Green Beans (Optional): For a softer texture, you can blanch the green beans by boiling them for about 2-3 minutes and then immediately transferring them into an ice bath. This step is optional but can help achieve a more tender inside while still keeping the outside crispy.
Make the Dry Ingredients: In a medium bowl, whisk together the flour, cornstarch, baking powder, garlic powder, onion powder, black pepper, and salt.
Add Sparkling Water: Gradually pour in the cold sparkling water (or regular cold water if you prefer) into the dry ingredients while stirring gently. The goal is to create a batter that’s smooth but slightly thick. Don’t overmix – the batter should be lumpy, not too smooth, to give that crispy texture once fried.
Coat the Green Beans: Dip each green bean into the tempura batter, ensuring it’s fully coated. Shake off any excess batter, as too much batter may prevent the beans from becoming crisp.
Preheat the Air Fryer: Preheat your air fryer to 375°F (190°C) for about 3-5 minutes.
Arrange in Air Fryer Basket: Lightly coat the air fryer basket with olive oil or cooking spray to prevent sticking. Arrange the battered green beans in a single layer in the basket. Make sure they don’t overlap too much to ensure even cooking. You may need to do this in batches depending on the size of your air fryer.
Air Fry the Green Beans: Cook the green beans at 375°F (190°C) for 12-15 minutes, shaking the basket halfway through the cooking time. The green beans should be golden brown and crispy when done.
