Ingredients
- Green Beans: You can save time by using 12 ounces of pre-trimmed green beans if you like.
- Olive Oil: No need to pull out the good stuff! Regular olive oil, avocado oil, or your favorite keto-friendly oil works well here.
- Lemon Juice: Make sure to use freshly squeezed lemon juice for the most flavorful dish.
- Sea Salt: You can adjust the seasonings to your personal preference.
- Black Pepper: Freshly ground black pepper gives the dish an extra kick.
- Parmesan Cheese: Grated parmesan cheese adds a nice salty finish. I recommend grating your own cheese because pre-grated cheese has additives. (And in my experience, it doesn't taste nearly as good!)
Step by Step
For the full recipe with measurements, see the recipe card at the end of the post.
First, start by prepping the green beans. Rinse and trim off any ends as needed. Place them in a large bowl.
In a small bowl, whisk together the olive oil, lemon juice, salt, and pepper. Pour this mixture over the green beans, and toss until everything is evenly coated.
Next, preheat your air fryer to 375° F.
Arrange the green beans in a single layer in the air fryer basket, working in batches as necessary. Cook for 6 to 8 minutes, shaking the basket halfway through.
Finally, add the parmesan and cook for another 2 minutes or until cheese is melted.
Pro Tips
- Make sure to trim off the ends of your green beans before air frying them - this will help them cook evenly and avoid them being too stringy.
- When you're done cooking, serve immediately so that your green beans stay nice and crispy!
- Don't forget to cook in batches if you need to. If you crowd your air fryer, you won't get the same results. (If you have an air fryer oven, you should be able to cook this recipe in a single batch and still get crispy green beans.)
- You can also add other spices to customize this dish - try some garlic powder, red pepper flakes, chili powder or Italian herb blend for a tasty twist for your string beans.
Serving Suggestions
Air fried green beans are a simple side that works with so many different proteins - from steak to seafood.
Try serving it with keto air fryer salmon, air fryer whole chicken, air fryer filet mignon, or air fryer short ribs.
