Ingredients
  

  • 2 white onions
  • 1 cup white flour
  • 1 teaspoon ground cumin
  • 1 egg
  • 1 teaspoon mixed herb seasoning
  • 1 cup buttermilk
  • 1 teaspoon cayenne
  • 1 teaspoon garlic powder
  • Salt and pepper

Instructions
 

  • Whisk the buttermilk and egg in a jar and set aside.
  • In a shallow bowl, combine flour and all the seasonings. Set aside.
  • Peel the onions and slice off their bottoms to create a flat surface.
  • Carefully make slits all around the onion, starting from the top around the head, right up to the bottom.
  • Dip the onion into the egg and buttermilk mixture.
  • Transfer the onion to the flour mixture and make sure it is well coated.
  • Move to a lined Air Fryer basket and air fry at 300 F for 20 minutes, spraying the onion twice with cooking oil. Remove once the onion looks golden brown and crispy.

Notes

  • Use firm, medium-sized white onions with an even shape so the petals are easier to cut and spread apart. Sweet onions are also a great option for a milder flavor.
  • Keep the root end intact when cutting the onion, as it holds all the petals together during coating and cooking.
  • Gently separate the onion petals before dipping them into the buttermilk and egg mixture to ensure the coating reaches between all the layers.
  • Let the excess buttermilk mixture drip off before coating the onion with seasoned flour to prevent a thick, gummy coating.
  • Spoon the seasoned flour between the petals and gently shake off any excess to get an even, crispy coating.
  • Spray the coated onion lightly with cooking oil, paying attention to any dry flour patches between the petals. Spray again during cooking for even browning.
  • Arrange the onions upright in the air fryer basket without overcrowding. Cook them in batches if necessary to allow proper air circulation.
  • Air fry at 300°F for approximately 20 minutes, checking that the coating is golden and crispy and the onion is tender. Larger onions may need a few extra minutes.
  • Adjust the cayenne pepper to your preferred spice level, or replace it with sweet paprika for a milder version.
  • Serve immediately with ranch dressing, chipotle aioli, or your favorite creamy dipping sauce for the best texture.
  • Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the air fryer at 300°F until heated through and crispy again.
