Enjoying the guilty pleasure of a Bloomin' Onion does not require a trip to Outback Steakhouse. This copycat Bloomin' Onion recipe will allow you to make this appetizer and its special dipping sauce at home without using a bloomin onion slicer or an onion flower cutter.

Also called an Awesome Blossom at Chili's or a Texas Rose at Lone Star Steakhouse & Saloon, a Bloomin' Onion is a whole sweet onion that is sliced, coated in a beer batter, and deep fried until golden brown.[1] While the onion cooks, the petals move away from the center of the onion, creating a blooming effect. The Bloomin' Onion is generally served as an appetizer with a spicy sauce seasoned with horseradish.[2]

Bloomin' Onion Recipe

  1. Heat the oil in a deep fryer or large deep pan to 375 degrees Fahrenheit.
  2. Peel the onions and slice off the root on one end only. Make 12 to 16 vertical cuts into the open end of the onions, making sure not to cut all the way through. Start by slicing through the center, then turn the onion and continue to slice all the way around. Leave about one inch of un-cut onion near the intact root. Peel back the onion petals slightly, but do not remove them from the onion.[6]
  3. Combine two cups flour, four teaspoons paprika, two teaspoons garlic powder, 1/2 teaspoon pepper, and 1/4 teaspoon cayenne pepper in a large plastic bag. Add the onions to the bag and shake to coat in the seasoned flour.
  4. Mix the remaining flour, cornstarch, paprika, garlic powder, salt and pepper in a large mixing bowl. Stir in the beer.
  5. Tap the floured onions to remove excess flour. Dip the onions into the batter to coat well. Allow excess batter to drip away.
  6. Carefully place the onions in the hot oil. Allow to fry for about 90 seconds, then turn it over and cook for another 90 seconds or until golden brown.
  7. Place on paper towels to drain. When cooled, remove the center portion of the onion petals, if desired, to create a space for the dipping sauce.

Though reportedly containing over 1,500 calories and 80 grams of fat per onion, the Bloomin' Onion remains a top choice at Outback Steakhouse restaurants around the world.[7] Outback has been serving the deep-fried appetizer since first opening in 1988 after company co-founder Tin Gannon created the concept. Following a search for the best onions for the task and careful selection of the 17 herbs and spices used in the batter, Outback Steakhouse has sold over 133 million Bloomin' Onion appetizers over 20 years.

  • To prepare a lower-calorie version of this recipe, cooks can skip the beer batter and bake the sliced onion at 425 degrees for 20 minutes. Remove the onion from the oven and then brush it with a mixture of butter and mustard, then sprinkle it with bread crumbs, salt, and pepper. The entire onion cooked in this way only contains about 260 calories.[8]
  • Cooks that prefer to omit the beer can use a batter consisting of egg, flour, and milk to get a similar battered texture instead.
