Steps to Make Outback Steakhouse Blooming Onion
- Prepare the Onion:
- Peel the onion and cut off about ½ inch from the pointy end (opposite the root). Place the onion cut side down and make 12-16 cuts from the top, stopping ½ inch from the root to create “petals.” Gently separate the petals to create the blooming effect.
- Mix the Batter and Coating:
- In a medium bowl, whisk together the flour, paprika, garlic powder, onion powder, cayenne pepper, salt, and black pepper.
- In another bowl, pour the buttermilk.
- Coat the Onion:
- Dip the onion into the flour mixture, ensuring all petals are coated. Shake off excess.
- Submerge the onion into the buttermilk, then return it to the flour mixture, coating thoroughly.
- Fry the Onion:
- Heat oil in a deep fryer or large pot to 375°F (190°C). Carefully place the onion in the oil, cut side down. Fry for 3-4 minutes, then gently flip and fry another 3-4 minutes until golden brown. Remove and drain on paper towels.
- Make the Dipping Sauce:
- In a small bowl, combine mayonnaise, ketchup, horseradish, smoked paprika, garlic powder, onion powder, and cayenne pepper. Mix well and refrigerate until serving.
- Serve:
- Place the blooming onion on a serving plate with the dipping sauce in the center or on the side.
