McDonald’s Top Chef Reveals all. See the recipe here and make it at home. In 2012, McDonald's admitted that the special sauce ingredients were not really a secret because the recipe had been available online for years. 

McDonalds Chef tells what is in the Big Mac Special Sauce and how to make it at home using Store Bought Ingredients.

Use These Ingredients For The Right Taste:
1 cup Hellmann's Mayonnaise or Best Foods Mayonnaise which are made by the same company
2 tablespoons Vlasic's Brand of sweet pickle relish
1 tablespoon French's Classic Yellow Mustard Brand
2 tablespoons white wine vinegar
1 teaspoon sweet paprika
1 teaspoon garlic powder
1 teaspoon onion powder

Mix all well and chill until ready to serve
​Use 2 tablespoon per sandwich. Makes 8 servings. (for a lesser amount cut the recipe in half.)
Place leftover Big Mac Sauce in a tightly closed container, refrigerated and it will keep several days.

​Big Mac: "Two all-beef patties, special sauce, lettuce, cheese, pickles, onions - all on a sesame seed bun." 

Note: Use 1 slice Kraft American cheese and 1 slice Kraft  mild cheddar cheese. Lightly toast the inner bun in a skillet. The onions are sweet onions, the pickles are Vlasic Dill Brand.

The Big Mac was created by Jim Delligatti, one of Ray Kroc's earliest franchisees, who was operating several restaurants in the Pittsburgh area. The Big Mac was invented in the kitchen of Delligatti's first McDonald's franchise which was located on McKnight Road in Ross Township, Allegheny County, Pennsylvania in the North Hills of Pittsburgh. The Big Mac first debuted at Delligatti's Uniontown, Pennsylvania restaurant in 1967 at a selling price of 45 cents. It was designed to compete with a similar Big Boy sandwich. The sandwich was so popular that it was added to the menu of all U.S. restaurants in 1968. One of its most distinctive features is a middle slice of bread ("club" layer) used to stabilize contents and prevent spillage

Big Mac Sauce is delivered to McDonald's restaurants in sealed canisters designed by Sealright, from which it is meant to be directly dispensed using a special calibrated "sauce gun" that dispenses a specified amount of the sauce for each pull of the trigger. Its design is similar to a caulking gun.

In 2012, McDonald's admitted that the special sauce ingredients were "not really a secret" because the recipe had been available online "for years". It consists of store-bought mayonnaise, sweet pickle relish and yellow mustard whisked together with vinegar, garlic powder, onion powder and paprika.
