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.

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 Big Mac Pasta Salad and Big Mac and Cheese!

Frequently Asked Questions

What’s the difference between sweet relish and regular dill relish? 

While both are made from cucumbers, regular dill relish is more common and is more tangy. Sweet relish has a lower amount of seeds than the regular dill relish, and sugar is added to it for sweetness. 

Is there yellow mustard in Big Mac Sauce? 

We do not put any yellow mustard in our yummy Big Mac sauce. However, it would be a great additional condiment to add to any homemade burger! 

Is Big Mac Sauce the same as Thousand Island dressing?

No. While they are quite similar in ingredients, Thousand Island dressing is made with red bell peppers and has a bit extra tanginess as well as possible ingredients like Worcestershire sauce and orange juice, depending on the makers recipe.

Key Ingredients in Big Mac Sauce

Making this homemade sauce is so easy! If you don’t already have all the simple ingredients in your own pantry, then you can easily find them at the local grocery store. Check it out! 

  • Creamy French: 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 the drive-thru craving hits.
  • Mayo: We used Best Foods mayonnaise in this recipe. Be sure to use real mayonnaise. Because of the delicacy of this recipe, Miracle Whip will not work as well. 
  • Sweet Relish: We are using a sweet relish, not the regular dill pickle relish which will be too tangy and not as sweet. 
  • Ketchup: You can use any ketchup you have in your pantry. 
  • White Vinegar: We are using a regular white vinegar, but you can substitute 1:1 for distilled white vinegar which has a lower acidity than regular white vinegar. 
  • Onion Powder: This dry spice is critical in giving the sauce a delicious depth of flavor. You won’t want to skip it! 
  • Salt: We’re only using 1/8th a teaspoon salt because the other ingredients already have salt in them.

Can I Make Big Mac Sauce Ahead of Time? 


This is a great sauce to make ahead of time. In fact, it will taste even better because of the time all the ingredients have to set in together. You can make it up to a week in advance and store in the fridge. Don’t store in the freezer because the mayo will not thaw very well. Enjoy!

  • 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 ½ 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!

  • Store: You can refrigerate any leftover sauce in an airtight container, like a sealed glass jar, for up to 1 week.

  1. This was definitely better after sitting in the fridge for a day. Still tasted great the first day too. Will definitely make again.

  2. 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

    1. It’s the best copycat recipe I’ve found. I actually like it better. It gets rave reviews from both family and friends alike. Try it!

  3. 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.

      1. Thank you for doing the Lord’s work! I make homemade Big Macs every once in a while and everyone who has had one says they are better than the original!

  4. 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..

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

  6. 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 ?
