Ingredients You’ll Need

Bringing the magic of Big Mac Sauce to your table is easier than you’d think! Each ingredient plays a key role—some add tang, others bring a hint of sweetness, and together, they create that signature creamy finish with just the right amount of zip.

Mayonnaise: Provides a creamy, luxurious base that holds all the flavors together.
Bottled French salad dressing: Adds a boost of tang, color, and a sweet undertone that’s absolutely essential for authenticity.
Sweet pickle relish: Brings bursts of sweet and vinegary crunch in every bite—don’t skip this one!
White onion (finely minced): Delivers a mild but noticeable sharpness and savory depth.
Apple cider vinegar: Perks everything up with a bright, slightly fruity acidity.
Granulated sugar: Balances out the tang and sharp edges with a touch of sweetness.
Salt: Enhances all the other flavors and keeps the sauce from feeling flat.
Black pepper: Adds a subtle warmth and just the right hint of spice for balance.

How to Make Big Mac Sauce

Step 1: Mix Everything Together

Grab a small mixing bowl and combine the mayonnaise, French dressing, sweet pickle relish, finely minced onion, apple cider vinegar, sugar, salt, and black pepper. Stir everything thoroughly until it becomes a unified, silky sauce, with no streaks of mayo or uneven chunks of relish—it should look smooth and lightly peach-colored.

Step 2: Transfer and Cover

Spoon the Big Mac Sauce into a lidded container—if you have a half-pint mason jar, it’s perfect for this! If not, any bowl covered tightly with plastic wrap will work. This step helps prevent the sauce from absorbing other fridge aromas and keeps it perfectly fresh.

Step 3: Chill for Flavor

Pop your covered sauce in the refrigerator and let it chill for at least two hours, but overnight is even better if you have the patience. Letting the Big Mac Sauce rest like this gives all those tangy, creamy, and sweet flavors time to meld together for that signature taste.

Step 4: Stir and Serve

Give your Big Mac Sauce a quick stir before serving, just to make sure every ingredient is evenly distributed. Now, it’s ready to be slathered, drizzled, or dunked whichever way you please!

How to Serve Big Mac Sauce

Garnishes

This sauce is lovely on its own, but if you want to get a little fancy, try topping it with a pinch of extra minced onion or a sprinkle of sesame seeds for a nod to your favorite takeout burger.

Side Dishes

Beyond burgers, Big Mac Sauce is a game-changer with golden fries, crispy onion rings, or even as a dip for veggie sticks. It’s also amazing with roasted potatoes or as a tangy companion for chicken tenders.

Creative Ways to Present

Turn your next gathering into a retro diner experience by serving Big Mac Sauce alongside sliders, as a salad dressing, or even as a drizzle over loaded nachos. Put it in a squeeze bottle for easy, artsy zigzags over your plates!

Make Ahead and Storage

Storing Leftovers

Store any leftover Big Mac Sauce in an airtight container in the refrigerator. It’ll keep well for up to a week, making it super convenient for last-minute burgers, wraps, or snack attacks.

Freezing

Freezing isn’t recommended for Big Mac Sauce, since mayo-based condiments tend to separate or become grainy after thawing. For best flavor and texture, stick with fresh batches stored in the fridge.

Reheating

Big Mac Sauce is best enjoyed cold right out of the fridge, as a cool contrast to hot burgers and fries. If it becomes too cold or thick, let it sit at room temperature for a few minutes and give it a good stir.

FAQs

Can I use homemade mayonnaise instead of store-bought?

Absolutely! Homemade mayo will make the Big Mac Sauce even richer and more flavorful—just make sure it’s good and creamy for the best results.

What can I substitute for French dressing?

If you don’t have French dressing on hand, a mix of ketchup and a splash of vinegar works well in a pinch, but the classic bottled version gives that nostalgic tang and color.

Is there a way to make Big Mac Sauce vegan?

Yes! Just swap in your favorite vegan mayo and choose a vegan-friendly French dressing. The rest of the ingredients are plant-based by default.

Why does the sauce need to chill for so long?

Chilling gives all the flavors time to come together, which transforms a simple mix of ingredients into that craveable, restaurant-style sauce—trust me, the wait is worth it!

Can I add other spices or tweaks to this recipe?

Definitely—feel free to experiment! Paprika or a pinch of garlic powder can add a fun twist, but for the classic Big Mac Sauce taste, stick with the original ingredients as your base.
