Does McDonald's Signature Sauce contain addictive substances? We think it must because it's so dang tasty, we think about it all day long! First unveiled alongside McDonald's Buttermilk Crispy Tenders in 2017, Signature Sauce is a sweet and tangy creamy sauce inspired by McD's iconic Big Mac Special Sauce.
We tried Signature Sauce on our fries, McNuggets and Double Cheeseburger and it tasted scrumptious on everything! The sauce, reminiscent of the American classic Thousand Island Dressing, is subtle in flavor and highlights anything it touches. Try it out for yourself, but be forewarned . . . you might not be able to stop!
