Of course, it’s perfect on a classic burger with all the trimmings. But my favorite way is to create a “Big Mac salad” night at home.

It’s a fun, interactive meal that always brings back the happiest memories of family dinners and laughter around the table.
Frequently Asked Questions

How do you make McDonald’s Big Mac sauce at home?
It’s surprisingly simple! You just whisk together mayonnaise, sweet pickle relish, yellow mustard, vinegar, spices, and a tablespoon of French dressing. Let it chill in the fridge for an hour to let all the flavors become best friends.
Is Big Mac sauce just Thousand Island dressing?
It’s a common misconception! While they share a similar creamy and tangy base, Big Mac sauce has a more complex flavor profile with distinct spices and that hint of French dressing, setting it apart from classic Thousand Island.

Yes, indeed! The sauce gets its signature sweet tang and little bits of texture from sweet pickle relish, which is finely chopped pickles in a sweetened brine.
