Bk stacker sauce recipe has become one of the most iconic, talked-about, and re-created fast-food condiments on the internet. Known for its creamy, tangy, smoky, slightly sweet flavor, this sauce gained a massive following thanks to Burger King’s legendary BK Stacker Burger—a towering combination of beef patties, cheese, bacon, and the unforgettable Stacker Sauce layered between each bite.
Today, home cooks, food bloggers, and fast-food lovers all try to recreate the authentic BK Stacker Sauce recipe, searching for the perfect balance of mayo, ketchup, relish, mustard, vinegar, and spices. This guide breaks down everything about Stacker Sauce—its taste, ingredients, variations, comparisons, storage, nutrition, usage ideas, and how to make the ultimate copycat version at home.
What Is BK Stacker Sauce?
BK Stacker Sauce is Burger King’s signature burger sauce, originally created for the 2006 launch of the BK Stacker Burger. Unlike typical Thousand Island-style spreads, Stacker Sauce is:
- Creamier
- Slightly smokier
- Less sweet
- More savory
- Balanced with relish, mustard, and vinegar
It quickly developed a cult following, especially because it was used generously on the Stacker Burger, famously built with two, three, or four beef patties stacked with cheese and bacon. Even long after Burger King removed and revived the burger, fans continued searching for a way to recreate the sauce at home.
Why Stacker Sauce Became Famous
The sauce stands out because:
- It enhances rich, meaty flavors.
- It’s simple but balanced—creamy, tangy, smoky, sweet, and savory.
- It pairs well with burgers, fries, chicken, wraps, and more.
- For years, Burger King kept the exact formula secret.
A homemade version became a viral topic online, and now thousands of home cooks replicate the authentic BK Stacker Sauce copycat recipe.
