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.

    Delicious! I’ve made this MANY times, exactly as written. Tonight, I subbed sweet chili sauce for the ketchup. Yummy!

    Great job on this sauce. I personally use both mayo & sour cream when making this dipping sauce. The tang from the sour cream seems to add something.

    I was given this recipe by an Outback employee years ago.
    Garlic powder is not in the original recipe.

    Also some of the measurements can be altered for taste.
    Oregano- just a pinch.

    pretty good! it’s not an exact replica of outbacks sauce but close. i use this recipe as a starting point and usually end up doubling the seasonings and adding an extra squirt or two of ketchup and it turns out extremely yummy! very happy to have found this recipe.

    Really good! I can’t say I’ve ever had Outback’s blooming onion sauce, but was just looking for a typical blooming onion sauce recipe to serve with onion rings. I added a dash of smoked paprika as well, just because I love it, it added a little smokey flavor without taking away from the original recipe.
