It takes just 7 ingredients to make our very popular copycat Big Mac Sauce recipe.

Scroll to the bottom of this post for the amount of each ingredient needed to make our copycat Big Mac sauce recipe.

  • Mayonnaise – I recommend making your own. Many supermarket brands include seed oils and sugar. Using a keto mayonnaise recipe will eliminate any “nasties”.
  • Dill Pickles – I use Polski Ogorki dill pickles. They are sugar-free. Check the labels of any shop-bought brands to make sure they have no sugar added.
  • Yellow Mustard – I use yellow American mustard or Australian mustard. Check the brands you use for any additives.

Step By Step Instructions

Mayonnaise with pickles in a bowl.

STEP 1 – Add all the ingredients to a mixer bowl

If mixing with a Thermomix or Magimix add wall the ingredients to the mixer. The pickles can be roughly chopped.

    I didn’t have any dill cucumbers/pickles so I added 2 tsp of your Ranch Spice Mix and I’m loving it! So much nicer than just plain mayo sometimes!
