Ingredients

Scale

Blooming Onion

  • 1 large yellow onion
  • 2 tablespoons olive oil
  • 1/2 cup all-purpose flour
  • 1 teaspoon paprika
  • 1/2 teaspoon garlic powder
  • 1/4 teaspoon cayenne pepper (optional)
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1/2 cup milk
  • 1 large egg

Dipping Sauce

  • 1/2 cup mayonnaise
  • 2 tablespoons ketchup
  • 1 tablespoon prepared horseradish
  • 1/2 teaspoon paprika
  • 1/4 teaspoon garlic powder
  • Pinch of cayenne pepper

Instructions

  1. Preheat the Oven: Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper to ensure easy cleanup and prevent sticking.
  2. Prepare the Onion: Peel the onion and slice off about 1/2 inch from the top, but keep the root end intact. Place the onion root side up on your cutting surface for stability.
  3. Cut the Onion into Petals: Make 12 to 16 evenly spaced cuts from the top of the onion down towards the root, stopping about 1/2 inch from the root to keep the onion intact. This creates the signature blooming petals.
  4. Separate the Petals: Gently pull apart the onion petals to loosen them, forming the blooming shape but being careful not to break the petals.
  5. Prepare the Flour Mixture: In a shallow bowl, whisk together flour, paprika, garlic powder, cayenne pepper if using, salt, and black pepper until well combined.
  6. Prepare the Wet Mixture: In another shallow bowl, whisk together the milk and egg until fully mixed.
  7. Dip the Onion in Wet Mixture: Carefully dip the entire onion into the milk and egg mixture, making sure to coat all the petals thoroughly. Allow any excess to drip off.
  8. Dredge in Flour Mixture: Next, coat the onion thoroughly in the seasoned flour mixture, ensuring each petal is covered. Gently shake off any excess flour to avoid clumping.
  9. Place and Drizzle: Set the coated onion upright on the baking sheet. Drizzle the olive oil evenly over the onion to help it crisp up and bake evenly.
  10. Bake the Onion: Bake in the preheated oven for 30 to 40 minutes, or until the onion petals are tender and golden brown with slightly crispy edges.
  11. Prepare the Dipping Sauce: While the onion bakes, whisk together mayonnaise, ketchup, prepared horseradish, paprika, garlic powder, and a pinch of cayenne pepper in a small bowl until smooth and well combined.
  12. Serve: Serve the blooming onion immediately while warm, paired with the prepared dipping sauce for a delicious, savory treat.

Notes

  • Do not cut through the root end to keep the onion intact when blooming.
  • Use a sharp knife for cleaner, safer cuts of the onion petals.
  • For extra crispiness, you can broil the onion for the last 2-3 minutes of baking but watch closely to avoid burning.
  • If you want a spicier dip, increase the amount of horseradish or cayenne pepper.
  • This recipe can be made gluten-free by substituting the all-purpose flour with a gluten-free flour blend.
  • Leftovers are best eaten the same day as the onion may lose its crispiness over time.
