Sauces & Condiments
This B&K coney sauce recipe delivers the signature velvety tomato base with its signature horseradish kick that makes every bite unforgettable. The secret lies in balancing sweet ketchup with tangy mustard and relish, then building depth with warm spices and a touch of vinegar.
What makes this sauce special is how the horseradish—often overlooked—creates that signature zing without overpowering the rich tomato flavor.
The foundation starts with a simple combination of ketchup, mustard, and relish, but it's the spices that elevate it to restaurant-quality. I use a blend of black pepper, garlic powder, and a hint of onion powder for warmth, then finish with a splash of vinegar to brighten the flavors.
The sauce should be thick enough to cling to hot dogs or burgers but still smooth enough to drizzle.
What you'll end up with is a sauce that's rich, slightly tangy, and just spicy enough to leave you wanting more. It's the perfect balance of sweet, savory, and a little heat—ideal for coney dogs, burgers, or even as a dipping sauce for fries.
The best part? This recipe comes together in just 15 minutes with ingredients you likely already have on hand.
For those who love a little extra kick, I include a spicier variation with added horseradish or hot sauce. Whether you're serving it at a backyard cookout or keeping it on hand for weeknight dinners, this sauce will become a staple in your kitchen. Let's get started!
Ingredients for b&k coney sauce
Nine simple ingredients blend into the iconic tangy-sweet coney sauce everyone loves.
| Ingredient | Amount | Notes |
|---|---|---|
| Ketchup 🍅 | 1 cup | High-quality, no sugar added preferred |
| Yellow Mustard 🥬 | ½ cup | Dijon or classic yellow style |
| Sweet Pickle Relish 🥒 | ¼ cup | Sweet, not dill or sour kind |
| Prepared Horseradish 🌶️ | 1 tbsp | Creama style preferred for creaminess |
| White Vinegar 💧 | 1 tbsp | For brightness and tang |
| Garlic Powder 🧄 | 1 tsp | Freshly ground preferred |
| Onion Powder 🧅 | ½ tsp | For subtle depth |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked for best flavor |
| Granulated Sugar 🍚 | 1 tbsp | Balances tanginess |
| Worcestershire Sauce 🍶 | 1 tbsp | For umami depth |
The ketchup and mustard are your foundation—Heinz and French's are the classic choices, but any good-quality brands work. Relish matters too; B&G or Vlasic sweet relish (the kind with seeds) gives that authentic texture. Horseradish is the secret weapon—creama style blends smoother than the crunchy kind. I grab mine from Trader Joe's when it's on sale, but any brand works. The spices? Freshly ground black pepper and garlic powder make all the difference—pre-ground loses flavor fast. If you're short on time, Penzeys sells pre-ground spices that stay fresh longer.
No horseradish? Hot sauce at half the amount adds heat without the texture. Short on relish? Extra mustard or a splash of pickle juice works in a pinch. Worcestershire sauce hard to find? Soy sauce at double the amount gives umami, but it'll be slightly saltier. The sugar can be swapped for honey or maple syrup if you prefer, but it'll change the balance slightly. Vinegar substitutes? Lemon juice works too, but it has a different brightness. Pro tip: Taste as you go—the sauce should be tangy-sweet with a hint of spice, not overwhelming in any one flavor.
This sauce keeps beautifully—1 week in the fridge in an airtight jar. Double the batch and freeze half for later; it reheats perfectly. I make a big batch every time, portion it into small jars, and keep them in the fridge for quick weeknight dinners. The flavors actually get better after a day or two as everything melds together. If it thickens too much, just add a splash of water or vinegar to loosen it up. Trust me, this sauce is worth making ahead for game days or cookouts.

Step-by-step instructions for B&k coney sauce
Here's how to craft that iconic Chicago Coney sauce—smooth, tangy, and with just the right horseradish bite.
Combine the Base Ingredients
In a medium saucepan, pour in the 1 cup ketchup and 0.5 cup yellow mustard. Stir them together over medium-low heat until they begin to warm through—about 2-3 minutes. You'll notice the mixture thicken slightly as the flavors start to meld. This initial step builds the sauce's velvety tomato foundation.
Add the 0.25 cup sweet pickle relish next, stirring constantly to distribute it evenly. The relish brings that signature sweetness that balances the tang. Let the mixture simmer gently for another 2 minutes, watching as the colors blend into a rich, deep red. This is where the sauce starts taking shape—keep your eye on it to prevent any scorching.
Add the Horseradish and Aromatics
Reduce the heat to low and carefully stir in the 1 tablespoon prepared horseradish. This is where the sauce gets its signature kick—just enough to add depth without overpowering. Next, add the 1 tablespoon white vinegar, 1 teaspoon garlic powder, and 0.5 teaspoon onion powder. Stir well to combine, letting the vinegar brighten the flavors while the powders add subtle warmth.
Let the mixture simmer for 3-4 minutes, giving everything time to meld. You should smell the garlic and horseradish coming through, but it should still taste balanced—not too sharp or overpowering. If it starts to thicken too much, add 1 tablespoon water to keep it smooth and pourable.
Balance and Finish the Sauce
Taste the sauce now—it should have a tangy, slightly sweet profile with a hint of horseradish. If it needs more depth, add the 1 tablespoon Worcestershire sauce and stir. For balance, sprinkle in the 1 tablespoon granulated sugar and 0.5 teaspoon ground black pepper, adjusting to taste. The sugar mellows the acidity, while the pepper adds a final layer of complexity.
Simmer for another 2 minutes to let all the flavors fully integrate. The sauce should be smooth, glossy, and ready to drizzle over hot dogs or coney sandwiches. If it's too thick, thin it with a splash of water or broth. If it's too thin, let it reduce slightly longer over low heat.
Rest and Serve
Remove the sauce from heat and let it rest for 5 minutes. This resting period allows the flavors to settle and deepen, ensuring a cohesive taste in every bite. Taste again before serving—adjust seasoning if needed, adding a pinch more sugar, pepper, or even a dash of vinegar for brightness.
Serve the sauce warm over hot dogs, coney sandwiches, or even as a dip for fries. The key to great Coney sauce is patience—letting the flavors develop slowly rather than rushing the process. This method guarantees a sauce that's velvety, balanced, and packed with that classic Chicago kick.
Pro Tips For Making B&K Coney Sauce
- STIR CONSTANTLY: This sauce is all about balance, and skipping the stir means the horseradish and vinegar will burn while the mustard and ketchup stay raw. I used to walk away for "just a minute"—bad idea. Keep a spoon in your hand and move it in steady circles until the heat hits 200°F, then simmer another 10 minutes without fail.
- DRAIN THE RELISH: Sweet pickle relish is packed with juice, and dumping it straight in turns your sauce into a watery mess. My grandmother made me strain it through a fine-mesh sieve first—yes, even if it looks tedious. The extra 30 seconds saves you from thinning out the sauce later.
- TASTE AS YOU GO: The magic ratio of ketchup to mustard (usually 2:1) can go wrong fast. I learned this the hard way when I eyeballed it and ended up with a sauce that tasted like a mustard bomb. After each addition of horseradish or vinegar, take a bite—adjust as you go, not all at once.
- USE A SPLASH OF WATER: If your sauce thickens too fast (thanks, ketchup), don’t panic. A tablespoon of water or even a splash of vinegar thins it out without killing the flavor. I was skeptical until I tried it—now I keep a small bowl of water nearby just in case. Works every time.
Dietary considerations for this recipe
Gluten-Free Adaptations
The original B&K coney sauce recipe is naturally gluten-free EXCEPT for the mustard and Worcestershire sauce. I always check labels—French's Classic Yellow Mustard is gluten-free, but Dijon-style mustards often contain wheat.
For Worcestershire, Annie's Organic or Lea & Perrins (check their gluten-free label) work perfectly. The rest of the ingredients—ketchup, relish, horseradish—are inherently safe. 🌾
Dairy-Free Considerations
This sauce is already dairy-free, but the creamy texture comes from the mustard and horseradish. If you want extra richness without dairy, stir in 1 tablespoon coconut cream or 1 teaspoon mayo at the end.
Both blend seamlessly and add a velvety finish. Just avoid sour cream or milk substitutes that might curdle when heated.
Low-Sugar Options
For a lower-sugar version, reduce the granulated sugar to ½ tablespoon and boost the tang with an extra ½ teaspoon vinegar. I also swap the ketchup for sugar-free ketchup (like Hunt's No Sugar Added) to cut sweetness while keeping the tomato base.
The horseradish and mustard provide enough depth to balance the flavors without extra sugar.
Spicy Variations
Want more heat? Add ½ teaspoon cayenne pepper or 1 teaspoon hot sauce (like Frank's RedHot) to the finished sauce. For a smoky kick, stir in ½ teaspoon smoked paprika after removing from heat.
I love adding 1 teaspoon of finely chopped jalapeño for fresh heat—just remove seeds if you prefer less intensity. 🌶️
Allergen-Friendly Substitutes
For egg-free needs, no changes are needed—this sauce has no eggs. If you're avoiding mustard, replace it with extra relish (¼ cup) plus 1 teaspoon apple cider vinegar for tang.
For horseradish allergies, use ½ teaspoon hot sauce instead. Always taste as you go—these swaps can alter the balance, so adjust other ingredients (like sugar or vinegar) to compensate.
Keto-Friendly Tweaks
To make this keto-friendly, skip the granulated sugar entirely and use 1 tablespoon erythritol or monk fruit sweetener instead. For a richer base, replace ¼ cup of the ketchup with tomato paste (unsweetened) to reduce carbs.
The mustard and relish are already low-carb, so no further adjustments are needed—just watch your portion sizes if tracking macros closely.

Frequently asked questions
What makes B&K coney sauce different from regular ketchup?
B&K coney sauce stands out with its signature blend of tangy mustard, sweet relish, and a subtle horseradish kick that regular ketchup lacks. The spices like garlic powder and onion powder add depth, while the vinegar brightens the flavor. It's thicker, richer, and designed to complement hearty dishes like Chicago-style hot dogs or burgers rather than just being a simple tomato condiment.
Can I make this sauce without horseradish?
Yes! If you dislike horseradish, substitute it with ½ teaspoon hot sauce or ¼ teaspoon extra black pepper for a similar kick. The sauce will still have its signature tangy-sweet balance, just without the sharp horseradish bite. Taste as you go to adjust the heat level to your preference.
How long does this sauce keep in the fridge?
This sauce stays fresh for up to 1 week when stored in an airtight container in the refrigerator. For longer storage, double the batch and freeze half in small portions. Thaw overnight in the fridge and reheat gently on the stove—no need to add extra liquid when reheating.
What's the best way to use leftover coney sauce?
Beyond hot dogs and burgers, this sauce is perfect for dipping fries, topping grilled cheese sandwiches, or even as a marinade for chicken wings. For extra flavor, simmer leftover sauce with a splash of beef broth to deepen its richness before using.
Why did my sauce turn out too thin?
If your sauce is too thin, it likely didn't reduce enough during simmering. Next time, cook it uncovered on low heat for 5-10 extra minutes, stirring occasionally. For instant thickening, mix 1 teaspoon cornstarch with 1 tablespoon water, stir into the sauce, and simmer for 2 minutes until it reaches your desired consistency.
