Secret Sauce is the perfect homemade topping for burgers and only takes 5 minutes to make! Simple ingredients like mayo, ketchup, mustard, pick relish, and garlic combine to make this creamy recipe. The flavor is so similar to McDonald’s Big Mac sauce and is also delicious on fish tacos or as a dip for fries.

The secret sauce is served from a small white dish.

We needed some sauce. And not just any sauce. A sauce that was so special it could complement the hubby’s juicy Air Fryer Hamburgers recipe perfectly.

Having been one of those kids who mixed my favorite drinks at the soda fountain, why not try it out with condiments?

A good bit of mayo, some ketchup, and a touch of mustard and sweet pickle relish.

With a few whisks, the secret sauce was quickly whipped up in less than 5 minutes.

I dipped my spoon in to take a taste, and wowzers!!

My concoction was kept secret from our guests until after I saw their reaction. When it was met with rave reviews, I let the cat out of the bag.

Now, this often-requested dip is affectionately known as “secret sauce” in our house and we serve it with fries, burgers, and even fish tacos.

It also just so happens to taste A LOT like the special sauce on McDonald’s Big Macs and In-n-Out burgers!

Mayo, ketchup, mustard, worcestershire, relish, salt, lemon juice, and seasonings are the ingredients in this recipe.

Ingredients

The simple ingredients you need to make this burger sauce recipe include:

  • Mayonnaise. Duke’s and Hellman’s are the best. You can also use miracle whip or even a vegan mayo.
  • Ketchup. Use whatever ketchup you have available. Opt for a sugar-free version if watching the carbs.
  • Mustard. Dijon mustard is preferred for the most flavor, but yellow can also be used.
  • Relish. Sweet pickle relish tastes best since it’s tangy and a bit sweet. You can also use dill relish if you don’t want the added sugar.
  • Worcestershire. This gives it an umami flavor and has a hint of molasses and vinegar.
  • Lemon Juice. Freshly squeezed is preferred, but you can use bottled or leave it out if you don’t have any available.
  • Paprika. Regular paprika is used, but you can also use smoked for more of a kick.
  • Garlic. Fresh, minced garlic is preferred, but ½-teaspoon of garlic powder can be substituted.
The secret sauce ingredients are mixed together in a bowl with a whisk.
