McDonald’s Big Mac Special Flavor

It’s undoubtedly the world’s most famous burger, from Philadelphia to the Philippines. The Big Mac has become a true food and pop culture icon, complete with a catchy jingle seared into the memory of millions of people around the world. But among the list of ingredients, there’s one that truly makes the Big Mac “special” — the Big Mac Sauce. This creamy, tangy, perfectly spiced, and ideally textured sauce is what elevates a Big Mac over any old double burger.   

Naturally, McDonald’s knows customers love it, even occasionally selling bottles of the sauce that can sometimes end up resold online for thousands of dollars. But you don’t need to drain your savings account or constantly make trips to the Golden Arches just to enjoy this tasty, distinctive condiment. With a deceptively simple group of ingredients, it’s easy to whip up at home for use on all of your favorite burgers, sandwiches, and other dishes. 

The Birth of the Big Mac and Big Mac Sauce

The Big Mac traces its roots back to the late 1960s. It wasn’t invented by McDonald’s itself; it’s actually the product of early franchise owner Jim Delligatti, who served the burger at his Pittsburgh-area locations in 1967. But it didn’t stay a Western Pennsylvania specialty for long. Within a year, corporate had taken notice, and the Big Mac was popping up on menu boards around the country. 

In the Big Mac’s earliest days, the sauce varied somewhat from restaurant to restaurant while sticking to the general theme and flavor profile. That all changed in 1972, when Mickey D’s standardized the recipe, ensuring each and every Big Mac has the same mouthwatering flavor. 

As for that flavor, don’t be fooled — McDonald’s special sauce is not just Thousand Island dressing in disguise, as many believe. While they certainly bear some similarities, there are notable differences that introduce the subtle differences that make Big Mac sauce so craveable.  

Why this is the best recipe for Big Mac Sauce

There are a few things better about homemade sauce than its flavor and ease of preparation. This Big Mac Sauce recipe has both, using common ingredients that may already be in your fridge or on your spice rack. Plus, it costs just pennies to whip up a batch, and comes together in just a few minutes of active work. 

Ingredients

There are no big surprises among the Big Mac sauce ingredients:

  • Mayonnaise – Creates the creamy base and signature texture
  • Relish – Adds tang, sweetness, and little bits of texture
  • Brown mustard (like Gulden’s) – Adds mild tang and a deeper mustard flavor
  • White vinegar – Sharpens the sauce and balances richness
  • Paprika – Adds warm flavor and a light color boost
  • Onion powder – Adds savory depth
  • Granulated garlic – Adds garlic flavor without overpowering the sauce
  • Ground white pepper – Adds gentle heat and a classic bite

While you can use any old relish, Indian relish yields the tastiest, most authentic results. This more complex relish has a spicier, tangier kick, with additional veggies beyond pickles. It’s available at many larger supermarkets as well as online, but you can also use ordinary sweet pickle relish if that’s all you have on hand. Do not use dill pickle relish. Those who are feeling especially adventurous can even make their own India relish.

How to make Big Mac Sauce

Tips for storing leftover sauce

  • Try to make it ahead of time for the best taste. Like many sauces, giving it a few hours to rest allows the flavors to blend into a cohesive, delicious final result. 
  • Don’t use the sauce cold. Remove only as much sauce from the fridge as you anticipate using before cooking your meal, and let it come to room temperature gradually. For food safety reasons, you should throw out any unused sauce and not put it back in the larger container in the fridge. 

What goes well with homemade Big Mac sauce

While this sauce is obviously a perfect fit for its namesake burger, it’s just as good on any other sandwich or wrap, providing a convenient, creamy flavor boost. It’s also an ideal dipping sauce for chicken nuggets, French fries, tater tots, onion rings, potato chips, or even fresh veggies. You can even use it as the salad dressing on a Big Mac Salad.

How to store

Store your Big Mac sauce in an appropriately sized, airtight container in the fridge. It’ll be good for up to a week. We don’t recommend freezing it for textural reasons and because it’s so easy to make fresh.

    I like several of the homey versions you publish. Big Mac sauce might be accurate, but I won’t try it. I decided in 1953 (I was 5 yr old) that every time I ate a Big Mac, a headache followed. I’ve tested it several times since, and there’s been numerous opportunities. Invariably I reach for the aspirin. The sandwich has the same ingredients as other varieties without the effect, just their tweaked tartar sauce, so….

    • GRINNING GOAT

      Try the 1968 McDonald’s Manager’s handbook for the original special sauce, it’s spectacular. It isn’t even 1000 Island dressing.
      It is just a few dashes of French dressing in that one. (Tastes just like the special sauce I know from McDonald’s, no Indian Relish, just 1 part regular sweet to 3 parts dill relish.)
      1000 Island was barely known until nor introduced to consumer market until after 1972. Maybe McD’s used 1000 Island in their later standardized version.
      There is about 8 or 9 separate ingredients in the original to include about 1 tsp of ketchup.

    My husband and I quit fast food so we are excited to try this! I didn’t find India relish in the store 🙁 so we will improvise. I also thought the color seemed a little on the lighter side ( plus I am not the biggest fan of mayo) So i am trying with a bit more of the dressing, and splashed a tiny bit of the juice in.
    I am setting it in the fridge overnight and excited to try it tomorrow!

    Thanks for sharing your recipe!

    Here is a version that tastes just like Big Mac Sauce
    1/2 cup mayonnaise
    2 Tablespoons french dressing
    4 teas sweet pickle relish
    1 Tablespoon finely minced white onions
    1 teas white vinegar
    1 teas sugar
    1/8 teas salt
    Combine all ingredients in a small bowl. Stir well. Cover and let set in the refrigerator for several hours or overnight. It tastes 100% like McDonalds. Go ahead, try it

      I understand that I am late, but your iteration of this sauce is off the chain!

      I walked in and my roommate was using it as a chip dip. [Redacted]

    I have used thousand island dressing on my burgers….and almost…but no…it is not the same sauce as McDonalds….i love that sauce.

    • Theresa

      I agree thousand island is not the same sauce. I also appreciate Stephanie posting these copyKat recipe’s. Ty

  5. kkbarringer

    The sauce is
    1 cup miricle whip
    2 Tbs. Dill relish
    2 Tbs sugar
    2 Tbs katchup
    mix well.
    I mix it to taste, so add or subtract what you like. We made this for our salad before they put thousand island in a bottle.
    That’s all mc Donalds uses

    I worked at a McDonalds in Ft Pierce FL in the late 1970’s. I opened up #10 cans of the “special sauce”. The labels said “Thousand Island Dressing”. Then the labels changed. The new labels (slapped on top of the old labels) said “McDonalds Special Sauce” yet was still the same old “Thousand Island Dressing” both on the label and in the can.

  7. DeeDee

    this is the recipe that i know of 1/4 cup salad dressing( miracle whip) 1/4 cup mayo, 3 tbs french dressing, 1/2 tablespoon sweet pickle relish, 1 1/2 tbs. dill pickle relish , 1 tsp sugar 1 tbs hydrated onions. mix together heat in microwave 25 sec remove and stir repeat then place in refrig for hr before serving. enjoy !!

  8. Dweyer

    Can’t be true. Worked at McDonald’s for quite a few years and I’m positively sure there’s onion in the sauce.
