Is there fast food more iconic around the world that a Big Mac? Two all beef patties, shredded lettuce, onions, tomato, the sesame bun… Oh, and of course that creamy sweet and tangy sauce unlike any other!

Even before they released the ingredient list in 2012, many attempts have been made to recreate this top secret sauce. McDonald’s didn’t give the amounts of each ingredient of course, so there’s been lots of testing to get it just right. And after many trials, we got it down!

You may be wondering if Big Mac Sauce is just Thousand Island dressing with a fancy name. While they are similar, Thousand Island has some warmer spices and this sauce has a lot more sweet pickle relish. Make sure not to get the dill pickle relish when making this sauce or it will be much more tangy!

There’s some debate on whether ketchup and french dressing should be used in Big Mac Sauce, they give it the most spot on taste, coloring, and balance of flavors. Plus they cut down on what you need to make this special sauce. While they aren’t listed in the official ingredients, they make this sauce the best copycat recipe.

You can make this sauce with any store-bought creamy french dressing, no need to use a fancy brand. We’ve tried Wishbone and Kraft brands and both worked well, plus these are relatively inexpensive brands that go on sale often so you can stock for whenever drive-thru craving hits.

The only thing better than making Big Mac Copycat Sauce at home is making a homemade Big Mac! To make a Big Mac taste spot on you’ll need some particular ingredients, so we have included a guide in this post for the best replica for a Big Mac.

Typically we offer variations on sauces, but this Big Mac Sauce Copycat is perfect the way it is. Instead, take a look at some of the other ways we love to serve this sauce below. Be on the look out for more delicious recipes using this special sauce, including Pasta Salad and Mac and Cheese!

  • Cheeseburger Casserole: The only thing our Big Mac-inspired Cheeseburger Casserole is missing is a drizzle of secret sauce!
  • Chicken Strips: If you were addicted to dipping nuggets in the limited time only Signature Sauce, dip Chicken Tenders in this Big Mac Sauce instead!
  • Bacon Cheeseburger Cups:  Chicken and french fries aren’t the only things you can dip in this condiment. Serve Bacon Cheeseburger Cups with a side of secret sauce with for a crowd-pleasing appetizer.
  • Cheeseburger Salad: Make a deconstructed Big Mac as a salad, just hold the sesame bun! Add a little more French dressing or vinegar if you like a thinner dressing. 

Homemade McDonald’s Big Mac

Make your own Big Macs at home and skip the drive-thru! This Big Mac guide makes 4 servings.

  • All-Beef Patties: Use 1 1/2 pound leans ground beef seasoned with salt and pepper formed into 8 thin patties.
  • Buns: You want sesame seed buns, and you will need 4 top buns and 8 bottom buns. The middle “bottom bun” is there to catch all the sauce.
  • Lettuce: Use finely shredded iceberg lettuce for authenticity and the best crunch.
  • Onion: Minced white onions are what McDonald’s uses. Mincing cuts down on their sharpness.
  • Cheese: Use 4 processed American cheese slices for a true Big Mac, or if you like extra you can double the cheese.
  • Pickles: You want dill pickle slices for the burger and sweet pickle relish for the sauce.
  • Assemble: Bottom bun, Big Mac Sauce, onion, shredded lettuce, cheese, patty, bottom bun, sauce, onion, lettuce, pickle, patty, and top bun. Enjoy!



  • Serve: Make sure to let this sauce refrigerate and meld together for at least an hour, but it’s best served the next day. Don’t keep at room temperature for more than 2 hours.
  • Store: You can refrigerate the Big Mac Sauce in an airtight container, like a sealed glass jar, for up to 1 week.
  • Freeze: Since this is a mayonnaise-based sauce, you don’t want to store it in the freezer. It is made so easily from pantry ingredients, just make it the day before.

  1. Was told They never use catchup or mayonnaise in their big Mac sauce they get their color from paprika and the main ingredient is creamy onion dressing not mayonnaise

  2. I keep this on hand. Everyone in the family loves it. I’ve tried numerous recipes from this site and have never been disappointed. This is my go-to “what’s for dinner?” site.

  3. This recipe tastes more like mayo…

    So after I made it I added more French dressing and sweet relish. Tastes better but not like Mac sauce..

  4. How long will this keep in fridge? Looking at ingredients, looks like it would last a good while, like mayo does. ??

  5. I have read in some of your recipes that you prefer to make your own Mayonnaise for your recipes , in this recipe did you use your own Mayonnaise recipe or a jar brand Mayonnaise to make this sauce ?
