Burger King Stacker Sauce Recipe You Can Make at Home

If you remember those epic Stacker burgers from the mid-2000s like I do, you know that creamy, tangy sauce was pure magic.

This burger king stacker sauce recipe brings back all those drive-thru memories!

I used to order those massive burgers just for the sauce – honestly, I’d ask for extra cups of it to dip everything. The Stacker line might be gone, but that legendary sauce lives on in my kitchen now.

After way too many late-night fast food runs and countless attempts to recreate the BK stacker sauce copycat, I finally did make it. This homemade version tastes exactly like the original that had us all obsessed back in the day.

My teenagers think I’m some kind of sauce wizard now. The best part? You probably have everything you need sitting in your pantry right now, and it takes literally five minutes to make.

What Makes Burger King Stacker Sauce so Irresistible

The magic of Burger King stacker sauce is all in the balance. It’s creamy, tangy, sweet, smoky, and just a little spicy—all at the same time.

The creaminess comes from mayonnaise, which gives the sauce a smooth, rich base. Ketchup adds a hint of sweetness and a light tomato taste.

Mustard brings in that bright tangy kick, while sweet pickle relish adds tiny bursts of flavor and a little crunch in every bite.

Burger King Stacker Sauce Ingredients

½ cup mayonnaise – This gives the sauce a creamy, smooth base that coats every bite and makes it rich and satisfying without being too heavy.

½ tablespoon ketchup – Adds a touch of sweetness and a hint of tomato flavor, giving the sauce a familiar, comforting taste everyone loves.

½ tablespoon yellow mustard – Brings a tangy kick that brightens the sauce and balances the sweet and creamy flavors perfectly.

1 tablespoon sweet relish – I love how it adds little bursts of sweetness and tang, plus a tiny crunch that makes the sauce more interesting.

½ teaspoon prepared horseradish – Adds just a subtle heat that wakes up your taste buds without overpowering the other flavors.

½ teaspoon Worcestershire sauce – Gives the sauce a deeper, savory flavor, tying all the creamy, sweet, and tangy elements together beautifully.

¼ teaspoon garlic powder – Adds a mild garlic flavor that enhances the sauce without being too strong or sharp.

¼ teaspoon onion powder – Brings a gentle savory note that rounds out the flavor and adds richness.

¼ teaspoon paprika – Adds a hint of smokiness and a soft red color that makes the sauce look as good as it tastes.

½ teaspoon lemon juice – Adds brightness and a little tang, keeping the sauce fresh and lively on your palate.

¼ teaspoon salt – Balances all the flavors and helps bring out the sweetness, tang, and creaminess in every bite.

¼ teaspoon black pepper – Adds a light peppery bite that rounds out the sauce with subtle warmth and depth.

How to Make Burger King Stacker Sauce Copycat

Step 1: Measure Ingredients

First, gather everything from your fridge and pantry. Then I always measure ahead so I don’t forget anything.

Step 2: Mix the Base

In a medium bowl, stir together mayonnaise, ketchup, and yellow mustard. Stir until the mix looks smooth and creamy.

Step 3: Add Flavor Boosters

Now add in the sweet relish, horseradish, and Worcestershire sauce. Stir again until it’s well blended.

Step 4: Season the Sauce

After you mixed them well, sprinkle in the garlic powder, onion powder, paprika, lemon juice, salt, and pepper. Mix until the sauce looks even in color and texture.

Step 5: Chill the Sauce

Cover the bowl with plastic wrap and chill it for about 15 to 30 minutes. This wait lets the flavors blend together so much better.

Step 6: Serve

Give it one more quick stir, and then use it right away on burgers, fries, or even as a dip.

Tips for Perfecting The BK Stacker Sauce

• Use fresh lemon juice for brighter flavor.
• Let the sauce chill longer if you have time—it only gets better.
• If you like it spicier, add a pinch more horseradish.
• A dash of smoked paprika gives extra smokiness.
• Stir right before serving for the best texture.

Ingredient Substitutions & Variations

Sometimes you may not have everything on hand, and that’s okay. Here’s what I’ve tried:

• Swap yellow mustard for Dijon for a sharper taste.
• Replace sweet relish with dill relish if you want less sweetness.
• Use light mayo for a lighter version.
• If you don’t like horseradish, try a little hot sauce instead.
• Paprika can be swapped with chili powder for more heat.

Foods to Pair with This BK Stacker Sauce

French fries – I love dipping hot, crispy fries in this sauce. It’s so much better than plain ketchup and makes every fry taste extra indulgent.

Grilled chicken – I spread the sauce over my grilled chicken, and it keeps the meat juicy while adding that creamy, tangy flavor I crave.

Fish sticks – The tangy, slightly sweet sauce pairs perfectly with crunchy fish sticks. It cuts through the fried coating and makes every bite more exciting.

Roasted veggies – I drizzle this sauce on roasted veggies. It turns simple carrots, broccoli, or cauliflower into something creamy, flavorful, and totally addictive.

Sandwich wraps – I like adding a smear of this sauce to wraps. It keeps the sandwich moist and adds a punch of zesty flavor in every bite.

Breakfast sausage – I sometimes use this sauce as a dip for breakfast sausage. It adds creaminess and tang that makes the savory sausage taste extra special.

How to Store & Keep Stacker Sauce Fresh

Once you make it, store the sauce in a sealed jar or container. Keep it in the fridge, and it will stay good for about 4 to 5 days.

Before pouring the sauce in your salad or enjoy as a dip stir or shake it because it can settle a little. Don’t freeze it—the texture changes too much.
