Bennett’s BBQ Sauce Recipe: Smoky Alabama-Style White Sauce

This Alabama-style white sauce brings a unique, tangy twist to traditional barbecue. I developed this recipe to capture that signature smoky flavor without overpowering the main dish.

Perfect for drizzling over smoked chicken or using as a dipping sauce, it delivers a creamy, zesty kick that stands out. The balance of vinegar and horseradish creates depth you won’t find in store-bought versions.

Ingredients for Bennett’s Bbq Sauce

Ten ingredients transform into this creamy, tangy Alabama classic with serious smoky depth.

The mayonnaise is the base, so Duke’s or Hellmann’s give you that perfect texture—skip the light versions. Horseradish at the grocery store varies wildly in heat, so taste before adding. Whole Foods and Publix usually have consistent quality. For the vinegar, Bragg’s apple cider vinegar (the one with the mother) adds a nice complexity, but any brand works in a pinch.

No horseradish? Extra black pepper plus a dash of hot sauce gets you close to the heat. Swap cider vinegar for white vinegar at half the amount—it’s sharper. Out of smoked paprika? Regular paprika plus a pinch of liquid smoke works, though the flavor won’t be as layered. The mustard can be Dijon if that’s what you’ve got (it’ll be a little sharper but still delicious).

This keeps 2 weeks in the fridge—the flavors actually deepen over time. Doesn’t freeze well (mayo separates), so make what you’ll use. Perfect for drizzling over pulled pork or as a dip for fries.

Step-by-Step Instructions for Smoky Alabama-Style White Sauce

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

Step 1: Combine the Base Ingredients

In a large bowl, whisk together the 2 cups Mayonnaise and 0.5 cup Apple Cider Vinegar until smooth. I use full-fat mayonnaise here for that signature creamy texture that defines Alabama-style sauce. The vinegar adds the necessary tang to cut through the richness.

At this stage, the mixture will look thin, but don’t worry. The mayonnaise base will thicken slightly as you incorporate the remaining ingredients. Make sure to scrape the bottom of the bowl to fully combine the vinegar, which tends to settle.

Step 2: Add the Flavorful Components

Stir in the 2 tbsp Prepared Horseradish, 1 tbsp Yellow Mustard, and 1 tbsp Granulated Sugar. The horseradish provides a subtle heat that builds complexity, while the mustard adds depth. The sugar balances the acidity from the vinegar and horseradish.

Here’s the thing—if you prefer a milder sauce, start with 1 tbsp Prepared Horseradish and adjust to taste. I like the full 2 tbsp for a noticeable but not overpowering kick. The mustard should be classic American yellow for authenticity.

Step 3: Season with Spices and Dry Ingredients

Add the 1 tsp Kosher Salt, 0.5 tsp Black Pepper, 0.5 tsp Garlic Powder, 0.5 tsp Onion Powder, and 0.5 tsp Smoked Paprika. These dry ingredients are what give the sauce its signature smoky, savory profile.

Use Diamond Crystal kosher salt if you have it—its coarse texture dissolves evenly without over-salting. The smoked paprika is non-negotiable; it’s what sets this apart from regular mayo-based sauces. Freshly ground black pepper makes a noticeable difference in flavor.

Step 4: Rest and Allow Flavors to Meld

Once all ingredients are fully incorporated, cover the bowl and refrigerate for at least 1 hour. This resting time allows the flavors to meld together. The sauce will thicken slightly as it chills, reaching the perfect consistency for drizzling or dipping.

I always make this the day before serving if possible. The flavors deepen and become more cohesive overnight. Give it a good stir before using, as the ingredients may separate slightly during storage.

Step 5: Adjust and Serve

Before serving, taste and adjust the seasoning if needed. If the sauce tastes too sharp, add a pinch more Granulated Sugar. If it needs more depth, a dash of additional Smoked Paprika can help. The sauce should have a balanced tang with a subtle smoky sweetness.

This sauce is incredibly versatile—use it as a dipping sauce for smoked meats, a dressing for pulled pork sandwiches, or even a unique topping for grilled vegetables. It keeps in the refrigerator for up to 1 week in an airtight container.

Pro Cooking Tips for This Recipe

Mayo Selection Matters

I always use Duke’s or Hellmann’s full-fat mayonnaise for the perfect creamy base. Light versions won’t give you that signature Alabama-style richness. The fat content is what makes this sauce cling beautifully to smoked meats. 💛

Horseradish Heat Control

Store-bought horseradish varies in intensity. Start with 1 tbsp, taste, then add more if you want more kick. I prefer Whole Foods’ prepared horseradish for consistent quality. Remember, the heat mellows slightly after resting in the fridge.

Vinegar Quality Tip

Bragg’s apple cider vinegar with the mother adds nice complexity, but any brand works. The key is using the full ½ cup for that essential tang that balances the richness. Never substitute white vinegar at full volume—it’s too sharp.

Spice Blending Secret

For the best flavor distribution, whisk the smoked paprika with the dry spices first before adding to the wet ingredients. This prevents clumping. Diamond Crystal kosher salt dissolves most evenly, so I always keep it on hand for sauces.

Resting Time

Don’t skip the 1-hour rest in the fridge. This lets the flavors meld and the sauce thicken slightly. I often make it the day before serving—the depth of flavor improves dramatically overnight. 🔥

Consistency Check

If your sauce seems too thick after resting, stir in 1-2 tbsp cold water. For separation issues, just whisk vigorously. The emulsion holds better when served at room temperature, so pull it from the fridge 30 minutes before using.
