In a small mixing bowl, stir together the mayonnaise, bottled French salad dressing, sweet pickle relish, finely minced white onion, apple cider vinegar, granulated sugar, salt, and black pepper until fully combined.
½ cup mayonnaise, 2 tablespoons bottled French salad dressing, 1½ tablespoons sweet pickle relish, 1½ tablespoons white onion, 1½ teaspoons apple cider vinegar, ½ teaspoon granulated sugar, ½ teaspoon salt, ¼ teaspoon black pepper
Transfer the Big Mac sauce to a small lidded container (a half-pint size mason jar works great), or cover the mixing bowl with a piece of plastic wrap.
Refrigerate the Big Mac sauce for 2 hours or up to overnight. This allows the flavors from all the ingredients in the sauce to develop and marry. Be sure to stir the sauce before serving.

Storage:

To Store: Store your sauce in an airtight container in the refrigerator for up to 1 week.
To Freeze: I do not recommend freezing this homemade sauce as the mayonnaise will not freeze and then thaw properly, and will alter the consistency of the sauce once thawed.

Tips:

If your Big Mac sauce has thickened up too much after an overnight refrigeration, you will need to allow it to come back to room temperature to loosen up. Alternately, you can whisk in 1-2 teaspoons of water to get the consistency you desire for your sauce.
You can substitute ketchup for the bottled French salad dressing in this recipe, but I do highly recommend the French dressing as it has added spices and seasonings that add to the uniqueness of the Big Mac Sauce.
You can substitute the yellow onion for the white onion. Be sure that you are very finely mincing the onion no matter which onion you are using.
Make sure you give your sauce enough time to chill in the fridge. This allows the flavors from all the ingredients in the sauce to develop and marry.
White vinegar can be used as a substitute for apple cider vinegar, but you will want to taste test it with 1 teaspoon and add the remaining ½ teaspoon if needed.
If using white vinegar as a substitute, then you will need to increase the granulated sugar to 1 teaspoon to balance the flavor of the sauce.
