Ingredients Equipment Method Notes

Ingredients
  

  • 1 pound fresh green beans trimmed and washed
  • 1-2 tablespoons olive oil for tossing
  • 1/2 teaspoon salt or to taste
  • 1/4 teaspoon black pepper optional
  • 1 teaspoon lemon zest freshly grated
  • 2 tablespoons parmesan parmesan cheese optional, grated

Equipment

  • Air fryer basket
  • Tongs
  • Measuring spoons
  • Sharp knife

Method
 

  1. Preheat your air fryer to 200°C (390°F) for about 3 minutes, so it's nice and hot when the beans go in.
  2. Trim the green beans by snapping off any tough stems or yellowed tips, then give them a quick rinse and pat dry to remove excess moisture.
  3. Place the beans in a large bowl and drizzle with olive oil, tossing gently to coat evenly. Sprinkle with salt and black pepper, then toss again to distribute the seasonings.
  4. Spread the seasoned beans in a single layer inside the air fryer basket, making sure they’re not overcrowded so the air can circulate freely and crisp them up.
  5. Roast for 8-10 minutes, shaking or tossing the basket halfway through, until the edges look crispy and slightly browned, and the beans are vibrant green.
  6. Once done, transfer the beans to a serving bowl and sprinkle with freshly grated lemon zest for a bright, zesty flavor.
  7. If desired, sprinkle grated Parmesan over the hot beans for a savory, cheesy touch, then toss gently to combine.
  8. Serve immediately while the beans are crispy and fragrant, with extra lemon wedges on the side if you like a little extra zing.

Notes

For extra crunch, roast the beans a minute or two longer, keeping a close eye to prevent burning. You can also customize seasonings with garlic powder, paprika, or herbs to suit your taste.
