Blooming onion dipping sauce is a delightful combination of mayonnaise, horseradish sauce, ketchup, and spices like cayenne pepper and paprika. I also like to add a hint of herbs such as oregano or parsley.

Blooming Onion Sauce is an excellent choice for pairing with blooming onions, onion rings, or fries in any form. Additionally, it works wonderfully as a dressing for salads or as a dip for a vegetable platter. It’s also tasty on burgers, grilled dishes, or sandwiches with cold cuts and meats. I sometimes even use it with fried green tomatoes.

How to Choose the Best Ingredients for Blooming Onion Sauce

Mayonnaise: Opt for a good quality mayonnaise or make your own from my mayo recipe. Mayonnaise with avocado oil is an excellent option for healthy fats. Alternatively, I often use Greek yogurt for a lighter consistency that allows me to pair it with more dishes. Yogurt also adds a slight tanginess and increases the protein content.

Ketchup: Choose a ketchup that you enjoy; I prefer milder varieties.

Horseradish Sauce: A standard horseradish sauce will work well, as most varieties have a similar taste.

Paprika: You can use sweet paprika powder interchangeably with smoked paprika or a mix of both.

Kosher Salt: This enhances the flavor of the other ingredients, but you can skip it if you're watching your salt intake.

Granulated Garlic: Granulated garlic is easier to incorporate into the sauce and provides a milder flavor compared to fresh garlic.

Dry Oregano: This balances and enhances the taste and aroma.

Black Pepper and Cayenne Pepper: These add a kick, so feel free to adjust the quantities according to your preferred level of spiciness.

Garnish: Chopped fresh parsley leaves or radish sprouts can be used for decoration and a nutritious boost.

Expert Tip for Success

For a smooth consistency, blend all the ingredients using a small blender or an immersion blender.
If you don’t have Greek yogurt, you can substitute it with mayonnaise.
Adjust the amount of horseradish to suit your tolerance for spice; it adds a distinctive zing.
The sauce tastes even better after chilling overnight.
