For the Blooming Onion:

  • 1 large sweet onion
  • 2 1/2 cups all-purpose flour
  • 2 tablespoons paprika
  • 1 teaspoon cayenne pepper
  • 1/2 teaspoon dried thyme
  • 1/2 teaspoon dried oregano
  • 1/2 teaspoon black pepper
  • 1/4 teaspoon garlic powder
  • 1 cup buttermilk
  • Vegetable oil for frying
  • Salt to taste

For the Dipping Sauce:

  • 1/2 cup mayonnaise
  • 2 tablespoons ketchup
  • 2 tablespoons horseradish sauce
  • 1/4 teaspoon paprika
  • 1/4 teaspoon salt
  • 1/4 teaspoon dried oregano
  • 1/4 teaspoon black pepper
  • 1/4 teaspoon cayenne pepper


1. Prepare the Blooming Onion:

  • Cut off the top of the onion (about 1/2 inch from the root end) and peel the skin.
  • Using a sharp knife, make 4 vertical cuts from the top of the onion towards the root end, leaving about 1/2 inch uncut at the bottom. This will create “petals.”

2. Mix the Dry Ingredients:

  • In a large mixing bowl, combine the all-purpose flour, paprika, cayenne pepper, dried thyme, dried oregano, black pepper, and garlic powder.

3. Coat the Onion:

  • Place the onion in a separate bowl and pour the buttermilk over it, ensuring it gets into the petals.
  • Carefully dredge the onion in the seasoned flour mixture, making sure to coat all the petals. Shake off any excess flour.

4. Rest and Repeat:

  • Let the coated onion rest for about 10 minutes to allow the coating to set.
  • Repeat the coating process once more for a thicker crust.

5. Heat the Oil:

  • In a large, deep pot or a deep fryer, heat vegetable oil to 350°F (175°C).

6. Fry the Blooming Onion:

  • Gently lower the coated onion into the hot oil, petals-side down.
  • Fry for approximately 3-4 minutes, or until the exterior is golden brown and crispy.

7. Drain and Season:

  • Carefully remove the fried onion from the oil and drain on paper towels.
  • Sprinkle with salt to taste.

8. Prepare the Dipping Sauce:

  • In a small bowl, combine mayonnaise, ketchup, horseradish sauce, paprika, salt, dried oregano, black pepper, and cayenne pepper. Mix well.

9. Serve and Enjoy:

  • Serve the Outback Steakhouse Blooming Onion hot with the prepared dipping sauce.
