The step-by-step instructions are about as easy as it gets:

  1. Mix – Simply add the ingredients to a bowl or jar and whisk to mix.
  2. Refrigerate – Cover and refrigerate for an hour or more allow the flavors to blend. You can serve immediately also if you can’t wait.
  3. Serve – Mix the sauce before serving. Slather it on burgers, use it for dipping or as dressing for a big mac salad.
  4. Store Leftovers – Store any leftovers in an airtight container in the fridge for up to 2 weeks. Mix the sauce before serving.

Making it healthy

Making this sauce healthy is actually pretty easy. With just a few tweaks to “common” ingredients that would normally go in a big mac sauce, we’ve made this recipe Paleo, Whole30 and Keto friendly!

Here are the swaps we made to make this recipe healthier.

  • Avocado oil instead of vegetable oil – Here is another link explaining why you shouldn’t eat highly processed industrial seed/vegetable oils.
  • Tomato paste, seasonings and vinegar instead of ketchup – Most of the ketchup bottles you find in the store are filled with sugar and other additives you don’t need.
  • Dill pickle instead of sweet relish – Using a dill pickle eliminates the extra sugar you’d get in a sweet relish and adds a tangy flavor that’s better than the original.
