Instructions

  • Take the frozen onion rings straight from the freezer without thawing, and lightly spray with olive oil if you prefer extra crispiness; preheat the air fryer.
  • Coat the air fryer basket with olive oil to prevent sticking and help achieve a golden, crunchy texture.
  • Arrange onion rings in a single layer inside the basket, avoiding overcrowding for even crisping; cook in batches if needed.
  • Set the air fryer to 400°Fahrenheit (200°Celsius) and cook for 7 minutes, checking halfway through to ensure even browning.
  • Flip each onion ring with tongs and continue cooking for another 7 minutes at the same temperature until golden and crispy; serve hot with your favorite dip.

Notes

  • Spread onion rings in a single layer to keep them crispy.
  • Avoid using extra oil to prevent greasiness.
  • Check for crispiness and add an extra minute if needed.
  • Let them cool slightly before serving for the best crunch.
