It’s no secret that McDonald’s Big Macs are beloved all over the world, primarily for the sweet and tangy sauce that’s slathered onto the burger buns. And while there have been plenty of rumors suggesting the special sauce is simply Thousand Island dressing in disguise, McDonald’s says otherwise.

After watching McDonald’s executive chef’s YouTube video on how to make the world-famous sauce, we headed into our own kitchens to nail down the specifics (the video provided the ingredients, but no amounts). Several tweaks and taste-tests later, we came up with the most delicious Big Mac sauce.

So skip the drive-thru and make a jar of this sauce at home, and you’ll have it ready whenever Big Mac cravings strike.

What’s the Difference between Big Mac Sauce and Thousand Island Dressing?

It turns out that despite tasting similar to Thousand Island dressing, ketchup is nowhere to be found in Big Mac sauce. Instead, the sauce gets its peachy-pink color from a dash of paprika, and signature creamy tang from a combination of mayo, mustard, and relish.
