Outback Steakhouse Bloomin’ Onion Dipping Sauce: Copycat Recipe

Homemade Fried Bloomin Onion with Dipping Sauce

Outback Steakhouse Bloomin’ Onion Dipping Sauce: Copycat Recipe

The Outback Steakhouse's website tells us that one out of every four appetizers ordered is a Bloomin' Onion. They sell eight million Bloomin' Onions each year. Outback Steakhouse founder Tim Gannon created the restaurant chain's iconic appetizer, the Bloomin' Onion, in 1988. Drawing inspiration from a traditional Australian food called the “Blossoming Onion,” Gannon accidentally created a quintessentially American food — a colossal, deep-fried onion with petals resembling a blooming flower. 

Gannon introduced a spicy, mayonnaise-based dipping sauce that adds a zesty kick to this fried onion dish, completing this perfect appetizer. If you have tried it, you know this dipping sauce flawlessly balances the richness of the Bloomin' Onion. If you love the Bloomin' Onion dipping sauce, you can now make a copycat recipe at home to enjoy on your homemade onion rings, not to mention many other foods.

What Ingredients Are In the Bloomin' Onion Dipping Sauce?

The Bloomin' Onion dipping sauce is a combination of several ingredients. This dipping sauce has a creamy base of mayonnaise, which is complemented by the sweetness and tanginess of ketchup. To add a spicy kick and depth of flavor, cream-style horseradish sauce is added.

While some people choose to omit the horseradish, our recipe includes it as we think it is an essential ingredient for this dipping sauce. However, be cautious with the horseradish. It is strong. Add it gradually to this recipe and taste as you go to avoid ending up with a sauce that is too intense for your liking.

Paprika adds a hint of smokiness and color to the sauce. Salt enhances the overall flavor while balancing out the sweetness and acidity. Additionally, dried oregano contributes a hint of herbal flavor, while ground black pepper adds a touch of heat. However, cayenne pepper can be added for those who prefer a spicier sauce.

Worcestershire sauce also enhances the flavor of the Bloomin' Onion's dipping sauce. Garlic powder provides a rich garlic flavor without the texture of minced garlic, while onion powder intensifies the onion flavor of this dipping sauce. However, you can adjust these ingredients as needed, such as leaving out the horseradish or using cayenne instead of black pepper.

Can You Buy the Bloomin' Onion Dipping Sauce?

Outback Steakhouse restaurants only serve the Bloomin' Onion dipping sauce at the restaurant. Sadly, it is not sold in stores. Many people have tried to recreate the sauce at home, coming up with their own recipes as a result.

How to Use Your Copycat Bloomin' Onion Sauce

Storing Your Copycat Bloomin' Onion Sauce

If you have any leftovers, you can store your copycat sauce in the refrigerator for up to five days. Additionally, you can prepare this sauce in advance as the flavors actually improve when given time to set. We recommend refrigerating your copycat sauce for 30 minutes to enhance the flavor.

However, we do not recommend freezing the copycat Bloomin' Onion dipping sauce or any mayonnaise-based sauces, really. When a sauce containing mayonnaise is frozen, the mayonnaise may undergo changes in texture and separate, consequently affecting the overall consistency of the sauce. Since it is easy to make, it is better to prepare a fresh batch when needed.
