Ingredients
  

  • ½ cup mayo
  • 2 tablespoon low carb pickle relish or chopped pickle with juice
  • 1 tablespoon sugar-free ketchup
  • ½ teaspoon yellow mustard
  • ¼ tsp+ monk fruit increase if swapping chopped pickle for the relish
  • ½ teaspoon garlic salt
  • ¼ teaspoon onion powder

Instructions
 

  • In a small bowl, add all of the ingredients for the Big Mac sauce, including the mayo, pickle relish, ketchup, yellow mustard, sweetener, garlic salt, and onion powder.
  • Combine all of the dressing ingredients together.
  • Serve over lettuce greens with cooked hamburger, cheese, onions, pickles, and any other burger toppings you love. This also makes a great dipping sauce, and sandwich spread. Enjoy!

Notes

Erythritol can be used in place of monk fruit, or use your favorite keto friendly sweetener to taste. Sweeteners like stevia are much stronger than erythritol or monk fruit and can't be swapped 1:1.
The dressing keeps up to 5 days in the fridge.
Be sure to use sugar free mayonnaise and ketchup like Primal Kitchen brand to keep the carbs as low as possible.
If you can't find low carb pickle relish, chopped pickles can be used in it's place. Just increase the sweetener to taste.
