Ingredient Notes

A large sweet onion will give the perfect flavor. Use a Vidalia or 1015 onion.

My preference for cooking oil is peanut oil, followed by vegetable oil. Any liquid oil will do, but peanut makes the onion crispier.

How to Prepare a Bloomin Onion

Preparing this onion isn’t too difficult. You’ll make a seasoned beer batter and flour mixture, cut and batter the onion, then deep fry it. Here are the step-by-step instructions:

  1. Whisk cornstarch, minced garlic, flour, paprika, and pepper until well blended.
  2. Add the beer and mix well until the batter is well combined.

  1. Combine flour with garlic powder, cayenne pepper, paprika, and pepper in a separate bowl. Mix until well blended.
  2. Peel the onions and place the root side on the cutting board. Use a sharp knife to slice the first 3/4 inches off the top of the onion. Then you will make 10 to 12 verticle cuts, but don’t go all of the way to the root.
  3. Separate the onion petals slightly, but do not do this too much or you will destroy the onion.

  1. Dip the onions into the bowl of flour and shake off the excess flour.
  2. Dip the onions into the batter and separate the petals to ensure they are thoroughly coated.
  3. Then dip the onion into the seasoned flour again.

  1. Heat the oil in a deep fryer until the oil temperature is 375 to 400°F. Place the onion in the fryer basket and deep-fry for 1½ minutes on one side. Flip the onion and fry for 1½ minutes, until golden brown.
  2. Lift the fried onion out of the hot oil with a wire skimmer or large slotted spoon and drain it on paper towels.

Recipe Tips

You may want to make sure your cutting board has a damp cloth under it so it doesn’t move.

If desired, you can cut out the center of the fried blooming onion and put a small cup of dipping sauce in it.

If you feel cutting the blooming onion is too much, try cutting it into petals, strings, or onion rings.

What To Serve With The Outback Blooming Onion

Be sure to serve it with plenty of blooming onion sauce! If you want other sauce ideas, pair it with honey BBQ sauce, ranch, sriracha, honey mustard, ketchup, and more. The crispy onion tastes amazing with virtually any sauce you can think of.

To use it as part of a meal, you can always serve it with Outback Steakhouse Mac and Cheese or Outback Steakhouse Queensland Chicken and Shrimp Pasta. It tastes fantastic with pasta because the crispy onion offsets the tender noodles and creamy sauce.

How To Store The Outback Steakhouse Onion

Keep the bloomin’ in an airtight container to retain its freshness until you plan to reheat it. Although it will last 4-5 days, the sooner you use it, the better.

What is the best way to Heal the leftover Bloomin Onion?

The best way to reheat the bloomin onion appetizer is to use the oven or air fryer. Unfortunately, with the microwave, the onion loses all of its crispiness (which is the best part!).

Heat the oven to 400 degrees Fahrenheit and bake it for approximately 10 minutes. If your onion is already a dark golden color, you might want to wrap it with foil so it doesn’t burn loosely.

You can set your air fryer to the same temperature and keep in mind it heats much faster this way, and it will take about half the time.

    Can’t have a steak without the Blooming Onion! I use this recipe with Outstanding Results Every time. A family fave. Ty for this great CopyCat recipe.

    I used this recipe not only for onion rings (I didn’t have enough oil for the whole onion). They were fantastic. I used my leftover batter and breading to make fried pickles. Excellent! Next time I fry chicken, I am going to use this. Oh- and the sauce is good on everything (except maybe dessert).

  3. Pat

    Just curious… Have you changed the recipe for the sauce? Mine is different. (I have the identical onion recipe tho). My recipes say “Source: Outback Steak House, Miami, FL. ” …can’t remember where I found it.
    I like the cold water hint – thanks people!

  4. Dennis

    We can try to get close to their recipes. The main thing they do is all of the seasonings for everything is shipped in. They are locked up. There isn’t beer in this dish at all. There is a machine that is used to cut the onions. Then they have to be soaked in water ton get them to open.

      • justin

        No there is not its a milk and egg wash pre dip and a straight seasoning mix there are only 2 items with beer in them at outback the beer batter for coconut shrimp has budweiser in it and the chicken breading batter has fosters in it. I don’t get the incentive to lying or maybe your a know it all waitress?

    • Katt

      What about an alcohol free beer like O’Doule’s ? If gluten is the issue instead of alcohol, there are now some gf friendly varieties available that would work. Without that beer-y flavor, the batter is just not right.

      I used 6 oz. of carbonated water (for the bubbles) and 6 oz. of apple cider vinegar (for the bitterness) and it worked out great! Added a subtle vinegary flavor to the batter that really complements the onion.

  5. ldawg

    There is no beer in the outback bloomin onion… the flour comes in a large box already seasoned and is a bright orange color.. soak onion in ice water squeeze excess out (don’t need to completely dry it) flour it lightly, dip in egg and milk wash, reflour and fry.. that’s it. No beer… only thing they use beer in is coconut shrimp

  6. MM91

    Tastes just like outback! If you have no taste buds…. Followed the recipe to a “T” without any problems, just tasted awful. Rather whoever wrote this had no taste buds, or has never had a bloomin onion at outback!

    The onion will come out better if, after slicing the petals, you float the onion upside down in ice water for fifteen minutes. The water must be as cold as possible. It will spread more easily, and lose fewer petals. This is how Outback gets it to bloom so nicely.

    Tried the Hooters fried pickles recipe the other night and it turned out great..I tried this recipe (Bloomin Onion) tonight and what a disaster..lol..The batter was so thick that I couldn’t get the onion into it without the onion breaking into pieces, plus after dipping it into the flour mixture, the batter wouldn’t stick to the onion. I ended up adding some bear to the batter to thin it out a bit but it didnt help. After dipping it into the flour mixture, it just wouldn’t stay on the onion..Any suggestions??

      Make sure the onion is dry, and coat it with starch first. Usually it’s easier if you also place it in the refrigerator for 30 minutes to chill down. Then do the batter dip after.

      Once you did the batter, put it on a rack for a minute before you do a second coat of flour.

    • Guest

      when you added the bear to the batter… did he get upset?

      and i also think a bear in the batter would be worthy of a spot on the evening news

      so was it?
