Ingredients

Scale

For the Crust:

  • For the Blooming Onion:
  • 1 large sweet onion (such as Vidalia)
  • 1 cup buttermilk
  • 1 cup all-purpose flour
  • 1 teaspoon paprika
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1/2 teaspoon cayenne pepper (optional)
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • Cooking spray or oil spray
  • For the Dipping Sauce:
  • 1/2 cup mayonnaise
  • 2 tablespoons ketchup
  • 1 tablespoon horseradish
  • 1/2 teaspoon paprika
  • 1/4 teaspoon garlic powder
  • 1/4 teaspoon salt
  • 1/4 teaspoon black pepper

Instructions

1. Prepare the Crust:

  1. 1. Prepare the Onion: Peel the onion and cut about 1/2 inch off the top. Leave the root end intact.
  2. 2. Turn the onion upside down (root side up). Using a sharp knife, make vertical cuts from the top down, stopping about 1/2 inch from the root to create ‘petals.’ Gently separate the layers.
  3. 3. Soak the Onion: Place the onion in a bowl and cover with buttermilk. Let soak for at least 30 minutes (or up to 2 hours).
  4. 4. Make the Coating: In a separate bowl, mix flour, paprika, garlic powder, onion powder, cayenne, salt, and black pepper.
  5. 5. Coat the Onion: Remove the onion from buttermilk, letting excess drip off. Dredge in the flour mixture, ensuring all petals are coated. Shake off excess.
  6. 6. Air Fry: Preheat air fryer to 375°F (190°C). Lightly spray the air fryer basket with oil. Place the onion root-side down in the basket and spray lightly with oil.
  7. 7. Cook for 10-12 minutes until golden and crispy. Check halfway and respray if needed.
  8. 8. Make the Sauce: While cooking, mix mayonnaise, ketchup, horseradish, paprika, garlic powder, salt, and pepper in a small bowl.
  9. 9. Serve immediately with dipping sauce.

Notes

For extra crispiness, double-coat the onion by dipping it back in buttermilk and flour a second time. If petals stick together, gently separate after the first few minutes of cooking.
