Let’s face it: the Big Mac is iconic, but the burger itself isn’t the star. The real magic is in the Big Mac Sauce Copycat. That creamy, tangy, slightly sweet sauce is what makes us crave it.
If you have been looking for the perfect Big Mac Sauce Copycat recipe to top your homemade burgers, you have found it. Forget the bottled stuff at the grocery store. This homemade version is fresher, cheaper, and frankly, tastes better than McDonald’s.
This sauce is the absolute “secret weapon” for our famous Blackstone Smash Burger. Trust us, you haven’t tasted a real burger until you add this sauce.
Why This Recipe Works (The “No Ketchup” Secret)
Many people mistakenly think this sauce is just Thousand Island dressing or mayo mixed with ketchup. They are wrong.
The authentic Big Mac Sauce Copycat gets its signature color and tang from paprika and mustard, not ketchup.
- Melding Flavors: The secret isn’t just the ingredients; it’s the resting time. Allowing the sauce to sit in the fridge lets the dried spices hydrate and blend into the mayonnaise.
Ingredients You Need

To make this Big Mac Sauce Copycat, you likely have everything in your pantry already:
- Mayonnaise: ½ cup (Use a high-quality brand like Hellmann’s or Duke’s).
- Sweet Pickle Relish: 2 tablespoons. (This provides the crunch and sweetness).
- Yellow Mustard: 1 tablespoon.
- White Vinegar: 1 teaspoon (cuts through the richness).
- Spices:
- ½ tsp Paprika (for color).
- ½ tsp Onion Powder.
- ½ tsp Garlic Powder.
- ¼ tsp White Pepper (optional, but adds a nice kick).
Step-by-Step Instructions
1. Mix the Base
In a small bowl, combine the mayonnaise, sweet pickle relish, and yellow mustard. Stir well until smooth.
2. Add the “Secret” Spices
Sprinkle in the paprika, onion powder, and garlic powder. Add the teaspoon of vinegar.
Whisk everything together until the Big Mac Sauce Copycat turns that signature salmon-pink color.
3. The Most Important Step: The Wait
This is where most people fail. Do not eat it yet!
Cover the bowl and place it in the refrigerator for at least 30 minutes (overnight is even better).
- Why? The dried onions and garlic need time to soften and release their flavor into the mayo.

How to Serve It?
Obviously, this Big Mac Sauce Copycat belongs on a burger.
- The Classic: Slather it on the top and bottom buns of our Blackstone Smash Burger.
- Fries Dipping: It makes an incredible dip for French fries or onion rings.
- Salad Dressing: Thin it out with a little milk and use it as a dressing for a “Cheeseburger Salad.”
Storing Your Secret Sauce
- Refrigerator: Store in an airtight container or a mason jar. It will stay fresh for up to 2 weeks.
- Freezing: Do not freeze. Mayonnaise-based sauces separate and become oily when thawed.
FAQ
Does Big Mac Sauce have ketchup?
No! The pink color comes from Paprika, not ketchup. Adding ketchup makes it taste like French dressing, which is incorrect.
Is this the same as Thousand Island?
Close, but no. Thousand Island usually contains ketchup and sometimes hard-boiled eggs. Our Big Mac Sauce Copycat is tangier and savory.
Can I make it spicy?
Absolutely. Add a pinch of cayenne pepper or a dash of hot sauce if you like a kick.
