This Blooming Onion Sauce is a bold, creamy, and tangy dipping sauce that mirrors the iconic condiment served with Outback Steakhouse’s legendary Bloomin’ Onion. It’s a flavor bomb of savory spices, a touch of heat, and a smooth, mayo-based texture that clings perfectly to every crispy bite. Whether you’re recreating the full blooming onion experience at home or just want a versatile sauce to elevate your snacks and meals, this copycat recipe delivers all the punchy flavor of the original—without the restaurant bill.
The beauty of this sauce lies in its balance: the richness of mayonnaise, the sharpness of horseradish, the warmth of paprika and cayenne, and the brightness of vinegar and garlic. It’s easy to whip up in minutes and even better after a short chill in the fridge, allowing the flavors to meld into creamy perfection.
Ingredients:
- ½ cup mayonnaise (preferably full-fat for richness)
- 2 tablespoons ketchup
- 2 tablespoons prepared horseradish (adjust to taste for heat)
- 1 teaspoon paprika (smoked or sweet, depending on preference)
- ½ teaspoon garlic powder
- ¼ teaspoon onion powder
- ¼ teaspoon ground cayenne pepper (optional, for extra heat)
- ¼ teaspoon salt
- ⅛ teaspoon freshly ground black pepper
- 1 teaspoon white vinegar or apple cider vinegar
- ½ teaspoon Worcestershire sauce (optional, for umami depth)
Instructions:
1. Combine the Base:
- In a medium-sized mixing bowl, add the mayonnaise, ketchup, and horseradish.
- Stir until the mixture is smooth and evenly blended. This forms the creamy, tangy base of the sauce.
2. Add the Seasonings:
- Sprinkle in the paprika, garlic powder, onion powder, cayenne pepper (if using), salt, and black pepper.
- Stir well to incorporate the spices thoroughly. The paprika adds warmth and color, while the garlic and onion powders bring savory depth.
3. Brighten the Flavor:
- Add the vinegar and Worcestershire sauce (if using). These ingredients cut through the richness and add a subtle tang and umami kick.
- Mix until the sauce is completely smooth and uniform in color.
4. Taste and Adjust:
- Give the sauce a taste and adjust the seasoning to your liking. Want more heat? Add a pinch more cayenne or horseradish. Prefer it tangier? A few extra drops of vinegar will do the trick.
5. Chill for Best Flavor:
- Transfer the sauce to an airtight container and refrigerate for at least 30 minutes before serving. This resting time allows the flavors to meld and intensify.
- It can be made up to 3 days in advance and stored in the fridge.
