The Ultimate Vegan Big Mac Sauce Recipe

For years, I’ve been obsessed with recreating that iconic Big Mac sauce at home, but with a plant-based twist. Sure, you can buy Big Mac sauce in a bottle at some stores now, but there’s something special about making it yourself – controlling the ingredients, adjusting the flavors to your taste, and knowing exactly what goes into it. After countless attempts and taste tests with both vegan and non-vegan friends, I’ve finally perfected a version that captures that nostalgic flavor while being completely plant-based.

While many people think Big Mac sauce is just thousand island dressing, there’s actually much more to it. This recipe goes beyond the basic mixture to create something that’s both familiar and uniquely its own. The best part? It’s an easy Big Mac sauce recipe that comes together in minutes using ingredients you probably already have in your kitchen.

Why You’ll Love This Recipe

This isn’t just another condiment – it’s a healthier Big Mac sauce that lets you enjoy that classic fast-food flavor while knowing exactly what goes into it. Unlike the original version or what you’ll find in a Big Mac sauce bottle, this recipe uses whole food ingredients and skips the preservatives and artificial flavors.

What makes this recipe special is its versatility. While it perfectly mimics that famous burger sauce, it’s also fantastic as a salad dressing, sandwich spread, or dipping sauce. Plus, it actually tastes better after sitting in the fridge for a day, making it perfect for meal prep.

Ingredients

Base Ingredients:

• 1 cup vegan mayonnaise – Forms the creamy base; I prefer ones made with aquafaba for the best texture
• 1/4 cup sweet pickle relish – Adds that crucial tangy crunch
• 2 tablespoons white onion, very finely minced – Must be fresh, not dried
• 2 tablespoons yellow mustard – Provides classic color and tang
• 1 tablespoon apple cider vinegar – Adds brightness and helps preserve
• 1 teaspoon maple syrup – Balances the acidity
• 1/2 teaspoon garlic powder – For depth of flavor
• 1/2 teaspoon onion powder – Enhances the fresh onion
• 1/4 teaspoon paprika – For color and subtle smokiness
• Pinch of sea salt – To taste

Optional Enhancers:

• 1/4 teaspoon turmeric – For color and anti-inflammatory benefits
• 1/8 teaspoon xanthan gum – If you want that commercial sauce thickness
• Fresh black pepper – To taste

Instructions

Step 1: Prep Your Ingredients

Start by very finely mincing your onion – the pieces should be tiny enough to almost disappear into the sauce. If they’re too large, they’ll overpower individual bites. Drain your pickle relish slightly if it seems very wet.

Step 2: Combine Base Ingredients

In a medium bowl, combine the vegan mayonnaise, pickle relish, and minced onion. Whisk until well combined. The key here is ensuring the onion is evenly distributed throughout the mixture.

Step 3: Add Seasonings

Add the yellow mustard, apple cider vinegar, maple syrup, garlic powder, onion powder, and paprika. Whisk thoroughly until all ingredients are fully incorporated and the color is uniform.

Step 4: Fine-Tune the Flavor

Taste and adjust seasonings. Add salt gradually – remember, the pickle relish already contains some salt. If using, add the turmeric for color and xanthan gum for thickness at this stage.

Step 5: Let it Rest

Transfer to an airtight container and refrigerate for at least 1 hour before using, though overnight is better. This resting time allows the flavors to meld and the onion to soften.

Pro Tips & Common Mistakes

After making this sauce countless times, here’s what I’ve learned:

• Mince the onion extremely fine – Large pieces will overwhelm the sauce
• Don’t skip the resting time – The flavor really develops in the fridge
• Use room temperature mayo – It blends more smoothly
• Taste and adjust – Brands of mayo and relish vary in saltiness
• Don’t over-sweeten – The relish already adds sweetness

Variations

• Extra Tangy Version – Add more vinegar and mustard
• Spicy Twist – Add a dash of cayenne or hot sauce
• Lower Fat Option – Use silken tofu-based mayo
• Raw Version – Use cashew mayo as the base
• Extra Creamy – Add 2 tablespoons of vegan sour cream

Storage & Meal Prep

This sauce keeps beautifully when stored properly:

• Refrigerator: Store in an airtight container for up to 2 weeks
• Do Not Freeze: The texture will change
• Best Used: Within the first week for optimal flavor
• Signs of Spoilage: If it develops an off smell or color, discard

Serving Suggestions

• Classic Style: On vegan burgers
• As a Spread: For sandwiches and wraps
• Dipping Sauce: For fries, onion rings, or raw vegetables
• Salad Dressing: Thin with a bit of plant milk if needed
• Bowl Sauce: Drizzle over grain bowls or roasted vegetables

FAQ

Q: How close is this to the original Big Mac sauce? A: Very close! The main difference is the use of plant-based mayo and natural preservatives.

Q: Can I make this oil-free? A: Yes! Use cashew-based mayo or silken tofu as your base instead of traditional vegan mayo.

Q: Why is my sauce too thin/thick? A: Different brands of mayo have different consistencies. Adjust thickness with xanthan gum or thin with a splash of plant milk.

Q: Can I use dried onion instead of fresh? A: While possible, fresh onion provides the best flavor. If using dried, rehydrate it first and use much less.

Q: How can I make it lower in calories? A: Use a lighter vegan mayo or make your own with silken tofu. You can also reduce the amount of maple syrup.
