It’s been over a decade since I’ve had a real Big Mac from McDonald’s, but when I first tried this recipe, it took me right back!

Ingredients You’ll Need 

  • Vegan mayonnaise – For this recipe, we used Vegenaise, but opt for your favorite store-bought vegan mayo. Avoid regular mayos because they contain egg and are not vegan-friendly. 
  • Ketchup – This condiment is naturally vegan and a staple we always keep stocked in our Vegan Fridge. Feel free to use any store-bought ketchup or if you’re up for it, make your own Homemade Ketchup from scratch! 
  • Mustard – We like to use stone ground mustard to give it a little extra kick, but a mild yellow mustard or even dijon mustard would work well, too! 
  • Sweet relish – Big Mac sauce contains pickle relish, so we used sweet relish. If preferred, opt for dill relish or even finely dice up some jarred pickles in a pinch! 
  • Apple cider vinegar – ​A small splash of acidity helps brighten up the big mac sauce recipe and brings it to life. If you’re out of apple cider vinegar, use regular white vinegar or a teaspoon of freshly squeezed lemon juice. 
  • Spices – ​We use a simple combination of garlic powder, onion powder, and paprika. If you love a garlicky flavor, feel free to replace the garlic powder with 1 minced garlic clove. You can also use smoked paprika for a smokier Big Mac sauce! 

Equipment Needed

How to Make Vegan Big Mac Sauce

  1. Combine ingredients. In a small or medium-sized bowl, add the mayonnaise, ketchup, mustard, sweet pickle relish, apple cider vinegar, and spices. Stir well to combine. 
  2. Thin out big mac sauce, if desired. ​If you find your sauce is too thick, add water 1 teaspoon at a time until the sauce reaches your desired consistency. 
  3. Serve. Serve immediately or store in the refrigerator until chilled. 

Serving Suggestions 

The best part about this homemade sauce is you can put it on literally everything. The obvious choice is spreading it on a sesame seed bun and making your own Vegan Big Mac with burger patties like these Black Bean BurgersGrillable Veggie Burgers, or store-bought Beyond burgers.

Recipe FAQs

How do I make a vegan Big Mac?

The McDonald’s Big Mac is made bottom to top using a bottom bun, Big Mac sauce, lettuce, cheese, burger patty, second bottom bun, Big Mac sauce, lettuce, pickles, chopped white onion, burger patty, and a top bun! Use this same formula using vegan ingredients! 

Is there dairy in Big Mac sauce?

The McDonald’s Big Mac sauce does not contain dairy (in the United States, at least!). It is not vegan because it contains eggs. This homemade version is free of both dairy and eggs. 

What is vegan mayo made of?

Vegan mayonnaise is typically oil-based, but depending on the brand or recipe, some vegan mayonnaise is made creamy with ingredients such as tofu or cashews instead of oil. If you’d like to make this Vegan Big Mac sauce oil-free and Whole Food Plant-Based, try making our friend Caitlin’s Easy Vegan Mayo Recipe

  1. Perfect! I did have to sub in dill relish rather than sweet (which I upped to about 2 Tablespoons), so I added a bit of agave, maybe 1 teaspoon.

  2. SO GOOD! So easy and tasty. This was the perfect sauce to add to my vegan burgers and sweet potato even on the side. Delicious 🙂 thank you!

  3. I made this yesterday to accompany Beyond Burgers I grilled up. We don’t keep sweet relish on hand, so I used dill instead. The sauce is very simple and delicious. It brought our burgers to the next level. I kind of wish I had tater tots or french fries to dip in it too. My 13 year old said, if she found out she could only ever have one more burger, it would be one with this sauce. Thanks for the recipe.
