McDonalds Big Mac Sauce Copycat Recipe

Our copycat Big Mac Sauce recipe could be the closest thing to Big Mac sauce, but even better because it uses fresh ingredients that you probably have in your pantry. And since the original coveted condiment doesn’t contain Thousand Island dressing, neither does this clone; instead, we incorporate French dressing to recreate the tangy flavor.

Creamy, zesty, savory, and slightly sweet, this McDonald’s special sauce recipe is so easy to make at home; it’s fresher than its fast food counterpart and can conveniently be stored in the fridge for a week.

Drizzle this big mac dressing on my Big Mac Salad, spread it between the buns of my Big Mac Sliders and Big Mac Sloppy Joes, use it as a dipping sauce for air fryer chicken nuggets, french fries, and onion rings, or slather it on sandwiches, burgers, and hotdogs, or pour it into a baked potato or pasta salad. A multi-purpose McDonalds burger sauce for smothering on meats or serving on the side!

Substitutions and Additions

  • Add Some Spices: Although it’s not necessary, you can add some savory spices to your sauce, like paprika, onion powder, and garlic powder. 
  • Replace The Relish: The sweet pickle relish adds the perfect amount of sweetness to the sauce. If you don’t like sweet pickle relish, use dill pickle relish or gherkin relish instead.

How to Make Big Mac Sauce

  1. Make The Mixture: Stir together the mayonnaise, salad dressing, sweet pickle relish, onion, apple cider vinegar, sugar, salt, and pepper until combined.
  2. Chill: Cover the sauce and chill in the fridge for 2 hours or up to overnight.
  3. Serve: Stir the sauce before serving. Enjoy!

Tips For Making The Best Big Mac Sauce

  • If your Big Mac sauce has thickened up too much after an overnight refrigeration, you must allow it to come back to room temperature to loosen up. Alternately, you can whisk in 1-2 teaspoons of water to get the consistency you desire for your sauce.
  • You can substitute ketchup for the bottled French salad dressing in this recipe, but I highly recommend the French dressing as it has added spices and seasonings that add to the uniqueness of the Big Mac Sauce.
  • You can substitute the yellow onion for the white onion. Be sure that you are very finely mincing the onion no matter which onion you are using.
  • Make sure you give your sauce enough time to chill in the fridge. This allows the flavors from all the ingredients in the sauce to develop and marry.

How to Store Big Mac Sauce

  • To Store: Store your sauce in an airtight container in the refrigerator for up to 1 week.
  • To Freeze: I do not recommend freezing this homemade sauce as the mayonnaise will not freeze and then thaw properly, and will alter the consistency of the sauce once thawed.

Frequently Asked Questions

Can I use vinegar instead of apple cider vinegar in my sauce?

Yes, white vinegar can be used as a substitute for apple cider vinegar, but you will want to taste test it with 1 teaspoon first and then add the remaining ½ teaspoon if needed. If you use white vinegar as a substitute, then you will need to increase the granulated sugar to 1 teaspoon to balance the flavor of the sauce.

Is Big Mac Sauce the same as Thousand Island dressing?

Big Mac sauce and Thousand Island dressing are similar in flavor, but they differ in ingredient ratios. Thousand Island dressing incorporates both ketchup and diced onion while Big Mac sauce doesn’t use either. Many Big Mac sauce recipes use French dressing instead, which gives it a tangier taste than that of ketchup.

What is the difference between Thousand Island dressing and French dressing?

While both Thousand Island and French dressings are tomato-based condiments, their ingredient lists are different. Thousand Island dressing combines ketchup, mayonnaise, sweet pickle relish, vinegar, diced onion, and garlic. In contrast, French dressing is made with olive oil, vinegar, yellow mustard, ketchup, sugar, and paprika, among other seasonings.
