A not-so-secret copycat of the famous Big Mac Sauce we all love! Serve it on burgers, as a dipping sauce, or on my Big Mac Salad! It keeps well in the fridge so you can make it in advance and use it all week long.

Why I Love This Recipe

  • Versatile – Serve on burgers, sandwiches, salads, and more.
  • Easy to Mix Up – Just mix in a bowl and enjoy!
  • McDonald’s Copycat – The fast food favorite burger sauce is easy to make at home!


All simple ingredients and you likely have most on hand already!

  • Mayonnaise – This is the main base of the sauce. I like to use regular, full-fat mayo, but you can swap in light mayo as well.
  • Ketchup – This gives the classic Big Mac Sauce color and, of course, Ketchup is a classic burger topping!
  • Yellow Mustard
  • Grated Yellow Onion – Finely minced onion can be used, but biting into the bits of raw onion in the sauce will taste very pungent.
  • Sweet Pickle Relish – If you don’t have sweet relish, you can finely mince bread and butter pickles. 
  • White Sugar – Just a small amount of sugar adds the right amount of sweetness.
  • Apple Cider Vinegar
  • Paprika – Paprika adds a sweet yet earthy taste and great color!

How To Make This Big Mac Sauce Recipe

See the recipe card below for full, detailed instructions

  1. Mix up Sauce – All you need to do is add all ingredients to a small bowl then whisk up until combined. 
  2. Chill or Serve – While the sauce can be used immediately, I prefer to chill in the fridge for an hour so the flavors can meld.  Serve on top of burgers, or on your favorite salad.

Keep leftover sauce refrigerated in an airtight container for up to one week. It’s a great option to make in advance!

Expert Tips

  • Grated onion – Grate the onion over a small bowl using a fine grater. Put all of the juice and grated onion in the sauce. 
  • Chill for at least an hour – While you can use immediately, the flavor is best after chilling for a bit.
  • Double it! This recipe doubles well and keeps well in the fridge for about a week.
