Big Mac Sauce is that irresistibly creamy condiment that makes the famous McDonald’s™ sandwich so special. This copycat tastes like the real thing, and even better, it’s super simple to make at home!!
McDonald’s sauce has just the right amount of tang and zip to dress up grilled burgers, sandwiches, or a variety of vegetables. You can even use it as a dip!
Big Mac Sauce
What’s really amazing about this recipe is that nobody can taste the difference when doing a side-by-side comparison of our big mac sauce and the real thing.
But unlike the fast food version, my copycat recipe is completely gluten-free, and much healthier! Knowing how to make big mac sauce gives you control over the ingredients. This way, with a few substitutions, you can even create an egg-free or dairy-free version if you want!
Looking for more restaurant copycat sauces and spreads? I’ve got you covered!
You can make copycat versions of the Taco Bell Nacho Cheese Recipe, Chipotle guacamole recipe, and even Olive Garden Italian dressing to serve with your home-cooked meals.
By looks alone, you may wonder if big mac sauce is simply thousand island dressing with a different name. The answer is no… but they are similar.
Both of the condiments have a creamy consistency and include pickle relish. But, McDonald’s Big Mac Sauce includes vinegar, and has a bit more pickle relish in it than Thousand Island dressing.
Also, although I haven’t been able to verify this, some people say that the special sauce also includes French dressing.
This homemade version is much tastier than the actual McDonald’s big mac sauce, which contains a variety of additives and preservatives.

How to Make Big Mac Sauce

Want a different consistency?
You can make a few simple adjustments depending on how you like it, or if you want to use this as a dip or salad dressing instead.
To thicken big mac sauce: Decrease the mayo and add some additional sour cream.
For a thinner sauce: Leave out the sour cream entirely.

Big Mac Sauce FAQ
How long does the secret sauce last in the refrigerator?
When kept in a sealed jar or container, McDonald’s copycat big mac sauce should be good for up to 1 week. Be sure to give it a good stir before each use.
The color changed – is that normal?
Yes! The longer it sits, the darker the color will become because it contains turmeric. It’s still safe to eat and the difference in color won’t affect the overall flavor.
When the Big Mac sandwich was first introduced in the 1960’s, it was known as the “Blue Ribbon Burger”. That name didn’t go over too well, so in the mid ’70’s, the restaurant chain launched a new advertising campaign. That’s when the Big Mac sandwich and that special sauce became famous.

Can I freeze the extra sauce?
Can I freeze extra sauce
We don’t recommend freezing Big Mac sauce because the mayonnaise and sour cream will separate as they thaw, causing the consistency of the sauce to become watery and “broken”. This is because the eggs and oil in mayo are emulsified and are unable to be stirred back together.
TSRI Team member,
This was a perfect addition to my homemade hamburgers! Loved that we had extra for the next day too.
Why do you say it’ll last a week in the fridge? It seems to me that all ingredients, except maybe onion, last a lot longer than that in fridge. I could never use all that in 1 week.
