Burger King Zesty Sauce Copycat

This Burger King zesty sauce is creamy, tangy, a little sweet, and has that signature kick. It’s an easy copycat dipping sauce that’s perfect with onion rings, fries, burgers, chicken, and sandwiches.

Why You’ll Love This Burger King Zesty Sauce Recipe

This Burger King zesty sauce is an elevated mayo-based dip. The mayo makes it creamy, the horseradish gives it that sharp zesty bite, the ketchup adds a little sweetness, and the vinegar and lemon juice brighten everything up.

When I tested this sauce, the horseradish was the ingredient that made the biggest difference. Too little and the sauce tasted like a basic burger sauce. Too much and it overpowered everything. Two teaspoons gives it that familiar kick without making it too intense.

I also like adding the smallest amount of soy sauce. It doesn’t make the sauce taste like soy sauce, but it adds a little savory depth that makes the mayo, mustard, ketchup, and horseradish taste more rounded.

The best part is that it takes just a few minutes to mix together. Let it chill for at least 30 minutes, and the flavor gets even better and it tastes closer to the real thing.

Ingredients

This copycat Burger King zesty sauce uses simple ingredients and comes together in one bowl.

Here’s what you’ll need:

• ½ cup mayonnaise
• 2 teaspoons prepared horseradish
• 2 teaspoons ketchup
• 1 teaspoon mustard
• 1 teaspoon white vinegar
• 1 teaspoon lemon juice
• 1 teaspoon cayenne pepper
• ¼ teaspoon salt
• ¼ teaspoon sugar
• 1 drop soy sauce

How To Make Burger King Zesty Sauce

Step 1: Add Everything To A Bowl

Add the mayonnaise, prepared horseradish, ketchup, prepared mustard, white vinegar, lemon juice, cayenne pepper, salt, sugar, and soy sauce to a small bowl. Use a bowl that gives you enough room to whisk without spilling.

Step 2: Whisk Until Smooth

Whisk everything together until the sauce is smooth, creamy, and fully combined. Make sure the horseradish, cayenne, mustard, and ketchup are evenly mixed into the mayo so every bite has the same zesty flavor.

Step 3: Taste And Adjust

Taste the sauce and adjust if needed. Add a little more horseradish if you want extra bite, a little more ketchup if you want it sweeter, or an extra pinch of cayenne if you want more heat.

Step 4: Chill

Cover the sauce and refrigerate it for at least 30 minutes. This gives the flavors time to blend and makes the sauce taste more like the original.

Step 5: Serve

Stir the sauce before serving. Serve it with onion rings, fries, burgers, chicken tenders, nuggets, sandwiches, wraps, or anything that needs a creamy, tangy dipping sauce.

My Tested Expert Tips For The Best Burger King Zesty Sauce

• Use prepared horseradish, not horseradish sauce. Prepared horseradish gives the sauce that sharp, zesty bite. Horseradish sauce is usually creamier and milder, which can make the final sauce taste less like the Burger King version.
• Don’t skip the chill time. Right after mixing, the sauce can taste a little sharp and separate. After 30 minutes in the fridge, the horseradish, vinegar, lemon, mustard, and cayenne blend into the mayo and the sauce tastes smoother.
• Start with 2 teaspoons of horseradish. Horseradish can vary by brand, so 2 teaspoons is a good starting point. After chilling, taste the sauce and add a little more if you want a stronger kick.
• Use a mayo you like. Mayo is the base of the sauce, so its flavor matters. A richer mayo will make the sauce creamier, while a lighter mayo will make it taste slightly tangier.
• Add the soy sauce carefully. You only need a tiny drop. It adds a little savory depth, but too much can make the sauce taste salty or take it away from that zesty fast-food flavor.
• Adjust sweetness with ketchup or sugar. If your horseradish or mustard tastes strong, a tiny bit more ketchup or sugar can balance the sauce without making it overly sweet.
• Use fresh lemon juice if you can. Bottled lemon juice works, but fresh lemon juice gives the sauce a cleaner brightness.
• Taste after chilling. The cayenne and horseradish become more noticeable as the sauce sits, so don’t make all your adjustments immediately. Chill first, then taste again.
