The good news? You don’t need the drive-thru to enjoy it anymore. With a handful of pantry staples and about five minutes, you can whip up this copycat Burger King Zesty Sauce at home. It’s bold, customizable, and versatile enough for fries, burgers, wraps, or even veggie platters.
Whether you love the heat, crave the creaminess, or simply want the best homemade dipping sauce for your onion rings, this recipe brings the flavor straight to your kitchen.
What You’ll Need (makes ~1 ¼ cups)
- ½ cup (120 g) mayonnaise – the creamy base that ties everything together
- 2 teaspoons ketchup – adds sweetness and color
- 1 teaspoon yellow mustard – tangy sharpness that cuts the richness
- 1 ½–2 teaspoons prepared horseradish – the key to Burger King’s zesty kick (adjust to taste)
- 1 teaspoon lemon juice – fresh brightness to balance the spice
- ½ teaspoon white vinegar – gives that signature fast-food tang
- ¼ teaspoon cayenne pepper – warmth and heat (add more for extra zing)
- ¼ teaspoon sugar or honey– softens acidity and rounds the flavor
- ¼ teaspoon fine salt – enhances all the other ingredients
- 2–3 drops soy sauce (optional) – a secret trick for umami depth
Ingredient Notes & Substitutions
- Horseradish: Brands vary in heat, start small and adjust after chilling. If you can’t find it, try a dab of wasabi paste + extra lemon juice.
- Mayo base: Regular mayo works best, but vegan mayo swaps in seamlessly.
- Vinegar swap: Apple cider vinegar adds a softer tang if you prefer less sharpness.
- Cayenne alternative: Smoked paprika for a milder, smoky twist.
How to Make Burger King Zesty Sauce at Home
Mix the base:
In a medium bowl, whisk together the mayonnaise, ketchup, mustard, horseradish, lemon juice, vinegar, cayenne, sugar, salt, and (if using) soy sauce until smooth and creamy.
Pro Tip: Use room-temperature mayo for a silkier texture and easier blending.
Chill the sauce:
Cover the bowl (or transfer to a jar) and refrigerate for at least 30 minutes. This allows the flavors to meld and the heat of the horseradish to settle into balance.
Pro Tip: If you’re in a rush, 10 minutes will work, but the sauce tastes closest to the Burger King original after a longer chill.
Taste & adjust:
After chilling, taste your sauce. Add extra horseradish or cayenne for more heat, a pinch of sugar if it’s too sharp, or an extra drop of lemon for brightness.
Pro Tip: Always adjust after chilling, not before. The flavor evolves as it rests.
Why This Version Wins
What makes this copycat Burger King Zesty Sauce better than the rest? It’s all in the balance and the little details that most recipes skip.
- The perfect balance of heat and tang – Too much horseradish overwhelms; too little makes it bland. This version hits the sweet spot: bold without burning.
- A secret umami boost – Just a couple drops of soy sauce deepen the flavor, making it taste closer to the real fast-food version.
- Customizable spice levels – Like it fiery? Add an extra pinch of cayenne. Want it mild? Dial back the horseradish. This recipe adapts to your taste.
- Restaurant-quality texture – Whisking everything until smooth and chilling properly gives that silky, spoonable consistency you expect from a dipping sauce.
- Versatility built-in – Other recipes focus only on onion rings, but this sauce works just as well on burgers, fries, wraps, or even roasted vegetables.
This isn’t just a quick knockoff. It’s a carefully tested version designed to capture why people love Burger King’s Zesty Sauce in the first place, while giving you the flexibility to make it even better at home.
Tips, Variations & Substitutions
One of the best things about this Burger King Zesty Sauce copycat is how easy it is to adapt. Here are a few smart tweaks depending on your diet, pantry, or heat preference:
Substitutions
- No horseradish on hand? Use ½ teaspoon wasabi paste + an extra squeeze of lemon juice. It won’t be identical, but it gives a similar punch.
- Out of white vinegar? Swap in apple cider vinegar for a gentler tang.
- Prefer smoky heat? Replace cayenne with smoked paprika for a milder, smoky finish.
Variations
- Vegan Zesty Sauce: Use vegan mayonnaise and swap the sugar for maple syrup or agave. The flavor stays bold, creamy, and satisfying.
- Low-Fat Version: Replace half the mayo with Greek yogurt and add a drizzle of olive oil to keep the texture smooth.
- Spicy Upgrade: Stir in a few drops of hot sauce or an extra pinch of cayenne if you like it fiery.
Pro Tips for Customizing
- Too spicy? Add a pinch more sugar or another teaspoon of mayo to mellow the heat.
- Too mild? A tiny dash more horseradish after chilling will wake it up.
- Batch cooking? Double or triple the recipe for parties, it stores well and tastes even better the next day.

Storage & Make-Ahead

FAQs
Not currently. Burger King only serves it in restaurants. The only way to enjoy it at home is with a copycat recipe like this one.
Yes, but mildly so. The horseradish and cayenne give it a gentle burn that’s balanced by mayo and a touch of sweetness. It’s more zesty than hot.
If you can’t find prepared horseradish, use ½ teaspoon wasabi paste plus a squeeze of lemon juice. It won’t be identical, but it brings a similar heat.
Freezing isn’t recommended. Mayo-based sauces separate and lose their creamy texture after thawing. Stick to refrigerating for up to 7 days.
Cut the horseradish in half and skip the cayenne. For extra creaminess, add a little more mayo or even a dollop of Greek yogurt.
