For the Onions
  • 8 pieces mini onions Sweet and tender, perfect for blooming.
  • 1 cup flour Ensures a crispy coating.
  • 1 tablespoon cornstarch For added crunch and lightness.
  • 1 large egg Binds the coating to the onions.

  • to spray none oil spray Helps achieve a nice golden color.
  • optional none dipping sauce Perfect complement to the onions.

Method
 

Preparation
  1. Peel the mini onions carefully, removing any papery skins.
  2. Cut a small portion off the top of each onion to create a flat surface.
  3. Slice the onions downwards towards the center, creating petal shapes while leaving the base intact.
  4. Soak the petals in cold water for at least 30 minutes to help them bloom nicely.
  5. Prepare the batter by whisking together the flour, cornstarch, and seasonings in a mixing bowl.
Cooking
  1. Preheat your air fryer to 400°F (200°C).
  2. In a separate bowl, whisk the egg with the milk until smooth.
  3. Remove the onions from the water and pat them dry with a paper towel.
  4. Dip each onion into the egg mixture, ensuring all petals are coated, then transfer them to the dry flour mixture.
  5. Shake off any excess flour and repeat the dipping process for a second layer for extra crunch.
  6. Spray the coated onions lightly with oil spray, then place them in the air fryer basket without crowding.
  7. Cook for 12-15 minutes, or until golden brown and crispy.
Serving
  1. Remove the mini onions from the air fryer and allow them to cool slightly on a wire rack.
  2. Serve with your favorite dipping sauce and enjoy fresh while warm.

Notes

Soaking the onions helps achieve the perfect bloom. For extra crispiness, increase cooking time slightly. Panko breadcrumbs can be used for a crunchier coating. Store any leftovers in an airtight container for freshness.
