Copycat Big Mac Sauce

If you’ve ever made my famous Big Mac Casserole, then you know this Big Mac sauce is a true low-calorie winner. It has the flavors of McDonald’s special sauce but only uses 4 simple ingredients. 

With only 4 ingredients that you likely have on hand you can have a quick and easy sauce for burgers, Big Mac Salad Bowls, Big Mac Wraps or just dipping your potatoes. It has the perfect balance of sweet tanginess without the miracle whip and goes great with just about everything. 

Why you’ll love this recipe:

  • Only 4 ingredients!
  • 58 calories for 1/4 cup.
  • Your own famous sauce at home. 

What is Big Mac Sauce?

The special sauce on the famous McDonald’s Big Mac Burger. It’s creamy, tangy, and slightly sweet. While some think it kind of sort of resembles a Thousand Island dressing or French Dressing but it is different.

Thousand Island dressing contains tomatoes, which the Big Mac Sauce does not have and French Dressing is oil-based. However, their sauce contains a LOT of ingredients. So we’ve simplified it down to 4 simple ingredients that you likely have on hand to get as close to the real deal as possible. 

Ingredients and Substitutes:

These are the main ingredients and substitutions for this Big Mac Sauce. See the recipe card below for the complete list of ingredients and instructions:
