  • 1 large sweet onion
  • ½ cup all purpose flour
  • 1 Tbsp. seasoning salt
  • 1 tsp. garlic powder
  • ½ tsp. cayenne pepper
  • 1 egg
  • ¼ cup milk
  • Cooking spray


  1. Cut onion into sections so that it forms the blooming onion petal effect. (Click here for full instructions.) Separate onion petals apart a bit.
  2. Whisk together flour and spices in a medium size bowl. Whisk together egg and milk in a medium size bowl. Dip onion into egg mixture, cut side up and spoon liquid over the onion so that all of the onion pieces are coated. Dip onion into flour mixture, cut side up and sprinkle flour mixture over the onion to coat each petal. Turn onion over and shake out any excess flour back into bowl. You don’t want too much flour, or it will turn gummy. Spray onion and petals with cooking spray, coating each piece and section of onion.
  3. Preheat air fryer to 370°F for a few minutes. Cook for 10 minutes. If it’s not golden brown, cook for an additional 5 minutes.
