Sauce for Blooming Onion

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

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

The Outback Bloomin Onion Sauce’s Secret

The Bloomin Onion dip sauce packs a bit more of a 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, it would undoubtedly be a big mistake to leave it out of this recipe to save a trip to the store.

For those unfamiliar with horseradish, it is a root with a pungent and spicy taste similar to wasabi, and 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 also find it in its original root form. The fresh horseradish is particularly flavorful, but unless you plan on making a lot of Outback Bloomin Onion sauce, stick to the milder and longer-lasting jarred variety.

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

It’s Delicious With More Than Just Onions

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 even mozzarella sticks! Are you trying to get your family to eat a little healthier? Kids (and their parents) will gobble up carrot and celery sticks, and even broccoli when they can dip them in a bowl of Bloomin Onion sauce!

Bloomin Onion sauce also makes 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 strong, so it is best to add it little by little at the end of the recipe and taste so you won’t end up with a sauce that is too pungent 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.

    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.
