How to Make Blooming Onion Sauce Recipe

Step 1: Mix the Ingredients

Grab a small bowl and combine the mayonnaise, ketchup, lemon juice, Worcestershire sauce, garlic powder, onion powder, paprika, and cayenne pepper if you want that extra kick. Stir everything together until you get a glossy, smooth mixture. This step is where all those flavors start chatting and coming to life.

Step 2: Season to Taste

Once your sauce looks well combined, it’s time for the important taste test. Add salt and pepper little by little, stirring and sampling until it hits just the right note for your palate. This personal touch is what transforms good sauce into a great one.

Step 3: Chill for Best Flavor

Although you can serve immediately, your Blooming Onion Sauce Recipe will taste even better if you refrigerate it for at least 30 minutes. This chill time allows the flavors to meld together beautifully, creating that irresistible depth that makes the sauce so addicting.

Step 4: Serve and Enjoy

Bring out your crispy blooming onions, onion rings, or any fried snack and serve them alongside this creamy, zesty sauce. Watching friends and family dive into this combo is one of life’s simple pleasures!
