BBQ Plaza Sauce Recipe: Tangy White Glaze for Pitmasters

This white BBQ sauce delivers a tangy, creamy alternative to traditional red sauces that pitmasters swear by. I developed this version after testing countless combinations to achieve the perfect balance of sweet, tangy, and slightly spicy flavors.

Use it as a finishing glaze for smoked chicken, a dipping sauce for fries, or a marinade for pork. The sauce keeps 1 week in the fridge, making it ideal for meal prep and grilling sessions.

Ingredients for Bbq Plaza Sauce

Nine ingredients blend into a tangy, creamy sauce that beats any store-bought.

The mayonnaise base is non-negotiable here—Duke’s or Hellmann’s give you that rich, creamy foundation you need. I grab mine at Costco for the big jars (worth it if you make this often). Horseradish is what gives it that signature kick, so don’t skip it. Look for it in the refrigerated section near the condiments—Bubbies or Gold’s are solid brands. The vinegar should be apple cider, not white, for the right tang.

No horseradish? Extra Dijon mustard at half the amount adds a similar sharpness. Swap honey for maple syrup if you want it vegan-friendly (or skip it entirely for a less sweet version). The garlic and onion powders are interchangeable with fresh if you prefer—just use one clove minced garlic and 1 tbsp minced onion. For a smoother sauce, strain out any horseradish chunks.

This keeps 1 week in the fridge in an airtight container. The flavors meld after a day, so it tastes even better later. Freezing isn’t ideal—it can separate—but if you must, use within 1 month and stir well after thawing.

Step-by-Step Instructions for BBQ Plaza Sauce

Here’s the method. Straightforward, tested, works every time.

Step 1: Whisk Together the Base Ingredients

In a medium bowl, combine the 1.5 cups mayonnaise and 0.5 cup apple cider vinegar. The vinegar will look like it’s curdling the mayonnaise at first—that’s completely normal. I use a wire whisk here for maximum control and to break up any lumps that form.

Whisk vigorously for 30-45 seconds until the mixture is completely smooth and uniform. You’re looking for a creamy, slightly thin consistency at this stage. The acidity from the vinegar will start to balance the richness of the mayonnaise, creating that signature tang we’re after.

Step 2: Incorporate the Flavor Boosters

Add the 2 tbsp prepared horseradish, 1 tbsp Dijon mustard, and 0.25 cup honey to the bowl. The horseradish adds a subtle heat and complexity, while the mustard provides depth and a touch of sharpness that complements the tangy base.

The honey will seem to thicken the mixture as you whisk it in. I prefer to add it in a slow drizzle while constantly whisking to ensure it incorporates evenly rather than pooling at the bottom. After 1-2 minutes of whisking, you should have a glossy, well-combined base.

Step 3: Season and Balance the Flavors

Sprinkle in the 1 tsp garlic powder, 1 tsp onion powder, 1 tsp salt, 0.5 tsp black pepper, and 0.25 tsp cayenne pepper. These dry ingredients might look like a lot at first, but they’re essential for building the complex flavor profile that makes this sauce special.

Whisk for another 30 seconds until all the spices are fully distributed. Taste and adjust the seasoning if needed—remember that the flavors will meld and intensify as the sauce rests. The cayenne adds a gentle warmth that builds gradually, so don’t be tempted to add more right away.

Step 4: Rest and Allow Flavors to Meld

Cover the bowl with plastic wrap or a tight-fitting lid and let the sauce rest at room temperature for at least 30 minutes. This resting period is crucial—it allows the flavors to marry and the mixture to thicken slightly as the mayonnaise absorbs the liquid ingredients.

I’ve found that the sauce reaches its peak flavor after 2 hours of resting. The horseradish mellows slightly, the spices become more harmonious, and the overall taste becomes more balanced. If you’re in a hurry, 30 minutes will work, but don’t skip the resting step entirely.

Transfer to an airtight container and store in the refrigerator for up to 1 week. The sauce will thicken further as it chills, but it loosens up beautifully when brought back to room temperature or warmed slightly.

Creative Variations of This Recipe

Spicy Kick Variation

For a bolder heat profile, increase the horseradish to 3 tbsp and add ½ tsp smoked paprika. The paprika deepens the flavor while the extra horseradish gives it a serious punch. I love this version with grilled shrimp skewers. 🌶️

Sweet Heat Twist

Replace the honey with ⅓ cup maple syrup and add 1 tsp chipotle powder. This creates a smoky-sweet balance that’s incredible on pulled pork sandwiches. The chipotle adds complexity without overwhelming heat.

Herb-Infused Version

Stir in 1 tbsp fresh dill or 1 tsp dried dill at the end for a bright, herby note. This pairs especially well with smoked chicken. I discovered this combo at a Kansas City BBQ joint and never looked back.

Smoky Depth

For a deeper, smokier flavor, add 1 tsp liquid smoke and reduce the vinegar to ⅓ cup. This mimics the flavor of traditional pit-smoked sauces. I use Wright’s liquid smoke for the most authentic taste.

Creamy Garlic Lovers

Double the garlic powder to 2 tsp and add 1 tsp onion powder. Roast 3 garlic cloves first for an even more intense flavor. This variation is perfect for garlic bread dipping or as a topping for baked potatoes.

Vegan Alternative

Swap mayonnaise for vegan mayo and use agave syrup instead of honey. Just Mayo or Hellmann’s Vegan work beautifully. The texture remains nearly identical to the original, with the same tangy kick.
