The iconic Bloomin Onion sauce

No trip to Outback Steakhouse is complete without an order or two of Bloomin Onions. Without the legendary Bloomin Onion dip sauce, the famous appetizer is little more than a fancy-looking onion ring.

The good news is that you probably already have most ingredients in your cupboard to whip up your Outback Bloomin Onion sauce. The next time you make a homemade Bloomin Onion or want to add a bit of zest to your next meal, try this quick and easy recipe.

Why everyone loves this sauce

This spicy sauce has the perfect balance of spices and just a bit of heat. The overall flavor of The Bloomin Onion dip sauce packs a bit more kick than most other condiments, and that power comes from horseradish. While not everyone has a jar of horseradish hanging out in the back of the fridge, leaving it out of this recipe would undoubtedly be a big mistake to save a trip to the store. Your taste buds will be delighted by this easy copycat Outback’s blooming onion sauce. You can recreate this recipe with ingredients found in your local grocery stores. What is one of the best parts of making this tasty sauce? No exotic ingredients are needed. 

For those unfamiliar with horseradish, it is a root with a pungent and spicy taste similar to wasabi. It is the ingredient that gives cocktail sauce its nose-clearing ability.

Most supermarkets only stock horseradish pre-shredded and preserved in a jar, but depending on where you shop, you may find it in its original root form. The fresh horseradish is exceptionally flavorful but stick to the milder and longer-lasting jarred variety unless you make a lot of Outback Bloomin Onion sauce.

If you choose to use fresh horseradish in the dipping sauce recipe, you may want to reduce the horseradish slightly.

This sauce can be used in so many different ways

You can’t find a better dipping sauce for onion rings or onion petals than this recipe, but Blooming Onion dip sauce is much more versatile than that. This sauce also works particularly well with any mild or sweet fried vegetables like fried mushrooms, sweet potato fries, and French fries.

Try it on breaded shrimp, chicken tenders, tater tots, or mozzarella sticks! Are you trying to get your family to eat a little healthier? Kids (and their parents) will gobble up carrots, celery sticks, and even broccoli when they can dip them in a bowl of Bloomin Onion sauce!

Bloomin Onion sauce is a wonderful condiment for hamburgers, chicken, and salmon. Experiment for yourself, and you will find that it’s the perfect accompaniment for any meal that needs a little zip.

Preparing and Storing Tips For the Outback Bloomin Onion Sauce Recipe

  • Be careful with the horseradish. Remember that horseradish is spicy, so it is best to add it at the end of the recipe and taste it so you won’t end up with a sauce that is too spicy for you to enjoy.
  • Prepare the sauce in advance. The sauce needs a few hours in the fridge to cool down and fully incorporate its flavors. Remember to store the sauce in an airtight container in the refrigerator and use it before two weeks to ensure it stays fresh.
  • Throw out any unused sauce that you serve. You should not re-refrigerate any sauce for health reasons. Avoid throwing out extra sauce by serving only a little at a time.
  • Storing the sauce. Store in the refrigerator for up to 10 days in an airtight container.

    Hi Stephanie
    I thought this was spot on ! I made this recipe after a 2 week long search. All the other recipes called for “horseradish sauce” I just knew that couldn’t be the same , the taste of the horseradish is just to prevalent. This sauce is absolutely amazing !!! Taking it to a cookout this weekend. I know it will be a hit.

    It did not seem to taste right when I first made it, but I followed the recipe and let it sit in the refrigerator for a while. That was the trick. It tastes fantastic.

  3. Jasmine

    Your recreations are always great & spot on! Can you try to make Outbacks Three Cheese Steak Dip? Its so good but don’t know the amounts to get the taste at home.

    I don’t know why anyone here is claiming that this recipe is “off.” I just bought an air fryer and was making some onion pedals and decided to Google the Outback recipe for this sauce and stumbled upon this. Just whipped it up and I’ll be damned if this isn’t spot on. So much so that I felt compelled to come back to comment so other people would feel a bit more confident to give it a go. I’m not sure how people deconstruct the flavors in things in order to backwards engineer them, but bravo. This is truly delicious. Thank you for posting this! This one is going on an index card. lol

    Wow is this good!!! We made onion straws last night and I made this. Doubled it for 4 people! Tasted exactly like Outback’s!!! Great job! Thanks!!!

    • james H shank

      I used to work at OB. It is not chili sauce. it was a seasoning packet just for bloom sauce. It did how ever have chili seasoning as an ingrediant. If you put mayo 1/2 cup and sweet thai chili sauce 1/4 cup and tad bit of sriracha sauce you would have bang bang sauce which is great too btw!!

    I CAN TELL YOU ONE THING THE DIPPING SAUCE DOES NOT HAVE OREGANO IN IT. I LOVE THIS DIP AND I Hate Oregano it is not in Out Backs dipping sauce!!!!!!!

      Your funny, clearly you are oblivious when your out to eat. I worked at outback and there is indeed oregano in the sauce. I won’t say how much, and this recipe is nowhere near the same, but it is tasty and worth making again. Lucky for myself I took pictures of all the recipes when I prepped at outback, empire brewery, delmonico’s and texas de Brazil.

    This is a huge hit at my house we use it on everything from onion rings and french fries to hambugers. It is great, I did tweak a little bit but it is great.

    I am looking for a copycat recipe for the fried zucchini dipping sauce at The Italian Oven. My husband is just crazy about it and I asked but they don’t sell it. I would be totally delighted if someone could help!!!!

    Thanks a bunch!!!!

    • admin

      I have a couple of suggestions. I don’t know where this restaurant is. I don’t have any information on this recipe, but I might suggest that you post a request on the message board in the recipe requests section.


    • Mitzi

      Hi Joyce: This recipe for the Bloomin’ Onion is great for that. I bake zucchini and use it for a dip. However, the only thing about this recipe is I add (tablespoon at a time, until it is to my taste) sour cream. The sour cream takes away the little bit of 1000 Island dressing taste and to me gives it that perfect sauce for dipping onion rings, zuch., fried green tomatoes, etc. Enjoy!
