What Is Blooming Onion Sauce?

This copycat version captures all the original flavor, so you can bring that restaurant experience into your kitchen.
Ingredients
Here’s everything you’ll need to make this bold, flavorful sauce:
- ½ cup mayonnaise – forms the creamy base.
- ½ cup sour cream – adds tanginess and depth.
- 3 tablespoons ketchup – for a touch of sweetness and color.
- 2 tablespoons prepared horseradish – for heat and sharp flavor.
- 1 teaspoon paprika – adds smokiness and color.
- ½ teaspoon kosher salt – to enhance flavor.
- 1 teaspoon granulated garlic (garlic powder) – for a savory boost.
- ½ teaspoon dried oregano – adds a subtle herbal note.
- ½ teaspoon ground black pepper – for mild spice.
- ¼ teaspoon cayenne pepper – optional, for an extra kick.
Instructions
1. Mix the creamy base:
In a medium bowl, combine the mayonnaise and sour cream. Stir until smooth and fully blended.
2. Add the flavor boosters:
Mix in the ketchup and horseradish. Stir thoroughly to combine.
3. Add the seasonings:
Sprinkle in the paprika, salt, garlic powder, oregano, black pepper, and cayenne pepper. Stir again until the sauce is completely smooth and all the spices are evenly distributed.
4. Chill for flavor:
Cover the bowl and refrigerate the sauce for at least 1 hour before serving. This allows the flavors to meld and develop.
