The Outback Steakhouse Bloomin’ Onion

Here’s a recipe to prepare The Outback Steakhouse Bloomin’ Onion:


  • 1 large sweet onion
  • 2 cups all-purpose flour
  • 2 tablespoons paprika
  • 1 tablespoon garlic powder
  • 1 tablespoon salt
  • 1 tablespoon cayenne pepper
  • 1 teaspoon black pepper
  • 1 cup buttermilk
  • Vegetable oil, for frying
  • Dipping sauce (e.g., Outback’s signature Bloomin’ Onion sauce)


  1. Start by preparing the onion. Cut off about half an inch from the top and bottom of the onion. Peel off the skin and discard. Place the onion upright on a cutting board, with the root end facing downward.
  2. Using a sharp knife, make vertical cuts around the onion, about 1/2 inch apart, but be careful not to cut all the way through. You want to create “petals” of onion that will open up during frying. It’s ideal to make around 12-16 cuts.
  3. In a large mixing bowl, combine the flour, paprika, garlic powder, salt, cayenne pepper, and black pepper. Mix well to ensure all the spices are evenly incorporated.
  4. Pour the buttermilk into a separate bowl. Dip the onion into the buttermilk, making sure it gets inside the cuts, and allow any excess to drip off.
  5. Place the onion in the bowl with the seasoned flour mixture. Use your hands or a spoon to gently coat the entire onion, ensuring that the flour mixture gets into the cuts.

  1. In a deep pot or fryer, heat vegetable oil to approximately 350°F (175°C).
  2. Carefully lower the coated onion into the hot oil, root-end up. Be cautious as the oil may splatter. Fry the onion for about 4-5 minutes, then carefully flip it over using tongs or a slotted spoon, and continue frying for another 4-5 minutes until it turns golden brown.
  3. Once cooked, remove the Bloomin’ Onion from the oil and let it drain on a paper towel-lined plate to remove excess oil.
  4. Optional: To enhance presentation, you can carefully use a knife to remove the center core of the onion before serving.
  5. Serve the Bloomin’ Onion on a plate and accompany it with a dipping sauce of your choice. Outback Steakhouse serves it with their signature Bloomin’ Onion sauce, which you can either purchase or try to replicate at home by combining mayonnaise, ketchup, horseradish sauce, and spices.
  6. Enjoy your homemade Outback Steakhouse Bloomin’ Onion!

Please note that deep-frying can be dangerous, so it’s essential to exercise caution when working with hot oil.
