Big Mac Secret Sauce Copycat Recipe

I remember going to McDonald’s as a kid. Like all kids, I loved going there to get the Happy Meal. It was great to open up that little box and see what was inside. More than anything, I loved the toy. I still remember the McDonald’s Changeables – Transformers that turn into burgers, fries, drinks and more. How cool is that? It is crazy now as the parent and seeing my own kids respond the very same way. The first thing they do go straight to the Happy Meal Toy. The toys have improved a lot since the days I was a kid.

As a parent, I am not overly excited now about going to McD’s. We go there on occasion when we are driving somewhere and looking for a quick bite to eat. The kids are always first to shout it out when we are discussing where we will go, but I prefer other burger joints much more. The one thing about McDonald’s that I do like though, is the Big Mac. It is not so much the burger that I like, because those patties are crazy small and there are almost no toppings. What I love about the Big Mac is that secret sauce! Some people say that the sauce is just Thousand Island salad dressing. It is close, but does not match it exactly.

Here is my recipe that come pretty close to perfectly matching the flavor of that sauce. I love making it at home and spreading it on a quality burger with lots of toppings!
