Homemade Outback Bloomin Onion Sauce Recipe (Better Than The Original)
That little bowl of creamy, peppery sauce that lands next to a Bloomin Onion is the reason most of us keep dipping long after the onion is gone. This Outback Bloomin Onion Sauce starts with a smooth mayonnaise base, then adds prepared horseradish, ketchup, paprika, and a touch of cayenne, so it tastes creamy first and spicy at the finish. It uses nine pantry ingredients and takes about 5 minutes to stir together with no cooking at all. Chill it for 30 minutes and it is ready for onion rings, fries, burgers, and fried shrimp.

The iconic Bloomin Onion sauce
Outback’s dipping sauce is what turns a fried onion into the Bloomin Onion experience. It is creamy and pale orange, with a clear horseradish bite and a warm, slow finish from cayenne.
This version is built for home kitchens. Everything goes in one bowl, with no cooking, blending, or special equipment. The sauce works on far more than onions, so one small batch rarely sits around for long.
Why this recipe works
- Mayonnaise carries the heat. The fat in the mayo spreads the horseradish and cayenne evenly and softens their sharpness, so the sauce tastes creamy before the spice arrives.
- Ketchup rounds the edges. A small amount adds sweetness, a little tang, and the soft orange color.
- Resting time matters. Right after mixing, the sauce can taste flat or uneven. A short chill gives the horseradish and spices time to blend into the mayonnaise, and one reader said that step made it taste right.
- Layered seasoning. Paprika, garlic powder, oregano, black pepper, and cayenne each add a small note, so no single spice stands out.
This copycat Blooming Onion Sauce has many uses
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. This sauce also works particularly well with mild or sweet fried vegetables, such as fried mushrooms, sweet potato fries, and French fries.
Try it on breaded shrimp, chicken tenders, tater tots, or mozzarella sticks! 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.
Bloomin Onion Sauce ingredients
Here is what you need to make the blooming onion dipping sauce (click on the recipe card to get the exact amount of the ingredients and the full recipe.) :
- Mayonnaise – I recommend using Hellman’s, Best Foods, or Duke’s
- Ketchup – I typically make this with Heinz brand
- Prepared horseradish – you can find this in the grocery store in the refrigerated section
- Paprika – this is for color and a hint of spice
- Salt – dials up the flavor
- Garlic powder – this gives the sauce a bit of a kick
- Dried oregano – balances out the flavor
- Black pepper – this gives a delicious note to this sauce
- Cayenne pepper – gives another layer of heat
Ingredient Notes
- Fresh horseradish root is much stronger than the jarred kind, so use a little less if you grate your own.
- Oregano divides readers. Some say it is essential, and others leave it out, so it is the easiest ingredient to adjust to your taste.
- Use jarred prepared horseradish, not horseradish powder. See the questions below for how to handle powder.
How to Make Outback Bloomin Onion Sauce
- Place all the ingredients in a bowl and stir to combine.
- Refrigerate the sauce for at least 30 minutes before serving.
Preparing and storing tips for the Outback Bloomin Onion Sauce recipe
- Start with a little less horseradish than you think you need. You can add more, but you cannot take it out.
- Make it ahead. The flavor settles in as it sits, so it is a good party sauce.
- Spoon what you plan to serve into a small bowl and keep the rest covered in the refrigerator.
What to serve with Outback Bloom sauce?
You can serve this sauce with so many things; here are some of my favorites!
- Fried shrimp
- French fries
- Outback Bloomin Chicken
- Outback Bloomin Onion
Storage & Reheating Instructions
- Refrigerator Storage: Store in an airtight container for up to 7 days. Stir before serving, since a little liquid can settle on top.
- Reheating Method: No reheating needed. Serve cold, straight from the refrigerator.
- Freezer Storage: Not recommended. Mayonnaise-based sauces separate when thawed.

Nice recipe . I will try this recipe.
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.
Am delighted to have run across this recipe.
This sauce was spot on! Now I am Looking for outback recipe for mustard vinaigrette dressing!! Love it.
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.
Yeah, sometimes you need to let the flavors mingle for a bit! I am glad it worked out for you.
This works good on sausage too! I make a little of this 30 minutes before naughty time.
He loves the taste and the double up on horseradish really opens him up !!!
Thank you so much!!!
I thought this sauce was right on the money. I use this sauce to dip wings.
Where is the measurement for it
I liked this, a lot.
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.
Thank you for the suggestion.
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
Thank you!
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!!!
I was told at outback the recioe is mayonnaise and chili sauce.
I think there is more going on there than that.
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!!
My kids are picky, and they liked it.
Best dipping sauce ever! Had it for New Year’s Eve party and it was a Hit! Everyone love, loved, loved It! With a blooming Onion! Thank you!
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.
You realize you taking photos of corporate recipes is illegal, correct?
And yes, I’m a professional chef of over 20 years to know this.

Where do you buy batter for blooming onion?
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.
This is wonderful with sweet potato fries!!
Trying to get Logan’s peanut Butter Sauce recipe and chocolate mousse they serve in their little pails over a brownie.
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!!!!
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 http://www.copykatchat.com in the recipe requests section.
Thanks!

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!
