What's The Big Mac Sauce Recipe?

For obvious reasons, McDonald’s official Big Mac sauce recipe is kept top secret. While the ingredients are listed on the McDonald’s website, there is a lot that we don’t know, such as the methodology, exact proportions of ingredients, and precise spice mix.

To give you an idea of what the sauce is made of, here are the official Big Mac sauce ingredients listed on McDonald’s Canadian website:

Soybean oil, Sweet relish (sugars, cucumber, water, vinegar, salt, xanthan gum, natural flavours, calcium chloride), Water, Vinegar, Liquid egg yolk, Onion powder, Spices (including mustard), Salt, Sugar, Garlic powder, Paprika extract, Propylene glycol alginate, Caramel colour, Hydrolyzed (corn, soy, wheat) proteins.

If we exclude the more difficult-to-source ingredients, we can conclude that the Big Mac sauce is made up of an emulsifier (such as oil), sweet relish, sugar, distilled vinegar, water, egg yolks, and a mix of spices, including onion powder, salt, garlic powder, turmeric, paprika.

The less recognizable ingredients, such as propylene glycol alginate, xanthan gum, calcium chloride, and soy lecithin, are used to emulsify, stabilize, and thicken the sauce. When making a Big Mac sauce copycat recipe at home, most people will simply use mayonnaise, which is already emulsified. Since we are making it vegan, we will use a vegan mayonnaise.

How to Make Vegan Big Mac Sauce

McDonald’s Big Mac sauce is the perfect balance between creamy and tangy. To achieve this, we basically need to combine a source of fat (vegan mayo for its creaminess) and acidity (distilled vinegar, as per the official Big Mac sauce ingredients).

Next, we need to sweeten it and season it with salt and the combination of spices that make up its flavour profile. To simplify the recipe, we used French dressing which contains mustard, paprika, sugar, and other ingredients that help complete the Big Mac sauce.

As per the official Big Mac sauce ingredients, we also need to add sweet relish to the mix to give the sauce its signature texture.

Once the ingredients for the sauce are well combined, the sauce should be put in the fridge for at least an hour. This step is important as it will allow the ingredients to come together to form the flavour profile we’re looking for.

Here’s exactly how you can make a vegan Big Mac sauce copycat recipe from home. If you’re not vegan, feel free to use whatever mayonnaise you have on hand.
