Step 5: Chill the Onion
  1. Place the coated onion in the refrigerator for 10 minutes.I learned this trick after several failed attempts. Chilling helps the coating stay attached during frying.

Step 6: Heat the Oil

Notes

  • Use a large sweet onion for the best blooming effect.
  • Keep oil temperature at 375°F for maximum crispiness.
  • Double-coating helps create a thicker restaurant-style crust.
  • The dipping sauce tastes even better after chilling for 15–20 minutes.
  • Leftovers can be reheated in an air fryer at 375°F for 4–5 minutes to restore crunch.
