Big Mac Sauce Copycat Recipe

McDonald’s Big Mac Sauce is a key element that contributes to the distinctive flavor of the Big Mac. While McDonald’s keeps the exact recipe a closely guarded secret, it’s widely believed that the Big Mac Sauce is a variation of Thousand Island dressing, or maybe a combination of Miracle Whip & Mayo. We tried both, with Miracle and without. Both delicious, so it’s up to each one to decide. Here is how you do it:


  • 1/2 cup mayonnaise
  • 2 tablespoons French dressing/Miracle Whip
  • 1 tablespoon sweet pickle relish
  • 1 teaspoon yellow mustard
  • 1/2 teaspoon white vinegar
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • Salt and pepper, to taste


  1. Combine Ingredients:
    • In a bowl, mix together mayonnaise, French dressing, sweet pickle relish, yellow mustard, white vinegar, garlic powder, and onion powder.
  2. Season:
    • Season the sauce with salt and pepper to taste. Mix well until all the ingredients are thoroughly combined.
  3. Chill:
    • For the best flavor, cover the sauce and refrigerate for at least 30 minutes before using. This allows the flavors to meld.
  4. Serve:
