Ingredients You’ll Need

You won’t believe how a handful of pantry staples come together to create that signature Big Mac Sauce flavor! Each ingredient has a crucial job—some bring creaminess, others tang, sweetness, or that little pop of savory onion. Let’s see where the magic happens!

Mayonnaise: This is the creamy canvas—make sure to use a high-quality mayo for the best texture and richness.
Bottled French Salad Dressing: Adds color, subtle sweetness, and a tangy backbone to the sauce. Classic orange French works best.
Sweet Pickle Relish: Delivers those iconic sweet-and-zippy pickly notes you know and love.
White Onion, Finely Minced: The tiniest chop is key for blending in—no big onion bites, just fresh flavor throughout.
Apple Cider Vinegar: Brightens up the sauce and balances the creamy richness. A little goes a long way!
Granulated Sugar: A pinch enhances the sweet pickles and rounds out the tang.
Salt: Don’t skip it—it sharpens all the flavors, making each bite pop.
Black Pepper: Adds a gentle warmth and complexity you might not expect, but will miss if it’s gone.

Variations

This Big Mac Sauce is delicious as written, but don’t be afraid to make it your own! With just a few tweaks or swaps, you can customize it to match your tastes, dietary needs, or what you have in your fridge.

Spicy Kick: Add a pinch of cayenne pepper or a few dashes of hot sauce for a bold, zesty twist.
Lighter Version: Use a light mayonnaise or swap in Greek yogurt for a tangy, lower-calorie option.
Extra Tang: Increase the apple cider vinegar or try dill relish instead of sweet for a more pronounced tartness.
Allergy-Friendly: Substitute a vegan or egg-free mayo if you’re catering to special diets—flavor still shines through!

How to Make Big Mac Sauce

Step 1: Mix It All Together

Start by grabbing a small mixing bowl and add the mayonnaise, French salad dressing, sweet pickle relish, finely minced onion, apple cider vinegar, sugar, salt, and black pepper. Stir everything together thoroughly until you have a smooth, homogenous, slightly peachy-colored sauce. Make sure those onions and pickles are evenly distributed in the creamy base!

Step 2: Container Up

Once your Big Mac Sauce is perfectly mixed, transfer it to a small lidded container—something like a half-pint mason jar works beautifully. If you don’t have a jar, covering your bowl with plastic wrap is just fine! The important thing is to keep it airtight.

Step 3: Chill (the Most Important Step!)

Pop your container of sauce in the fridge for at least 2 hours, or—if you have time—overnight. This is where the magic really happens: the flavors blend and deepen, giving you that Big Mac Sauce taste you can’t get enough of. Give it a good stir before you serve!

Pro Tips for Making Big Mac Sauce

Finely Minced Onion Mastery: Take a minute to mince your onion as tiny as possible—this is what separates a silky sauce from a chunky one!
Taste and Adjust: Everyone’s palate is different, so after chilling, taste your sauce and tweak the vinegar or sugar if you want a brighter or sweeter note.
Don’t Rush the Chill: Even if you’re hungry now, the flavor really does get better after chilling—try for a minimum of 2 hours, but overnight is unbeatable.
Use a Glass Jar: If possible, store your Big Mac Sauce in glass for best freshness and no lingering flavors from past meals.

How to Serve Big Mac Sauce

Garnishes

Big Mac Sauce shines brightest when served with classic toppings—think a sprinkle of extra minced onion, a few sesame seeds, or chopped dill pickles on top. It also looks beautiful with a dusting of paprika for a hint of color and warmth.

Side Dishes

You’re not limited to burgers! Try using your Big Mac Sauce as a dip for crispy fries, baked potato wedges, or crunchy veggie sticks. It’s phenomenal on the side of fried chicken tenders, and also livens up the simplest salads as a creamy, tangy dressing.

Creative Ways to Present

Level up your next BBQ by serving Big Mac Sauce in a squeeze bottle for easy drizzling, or pour it into a fun little mason jar for a retro vibe. For a party, serve it as part of a “burger bar” so everyone can customize sliders, sandwiches, and wraps—the possibilities really are endless!

Make Ahead and Storage

Storing Leftovers

Leftover Big Mac Sauce keeps like a dream! Simply store it in an airtight container in the fridge for up to one week. A quick stir before each use will keep it luscious and perfectly blended.

Freezing

While it’s safe to freeze, Big Mac Sauce may separate or lose creaminess after thawing. For that silky texture and bold flavor, I recommend making a fresh batch when you need it.

Reheating

Big Mac Sauce is best enjoyed cold or at cool room temperature. If it’s been in the fridge and feels a little too firm, let it sit out for 10 minutes before serving—no actual “reheating” required!

FAQs

Can I make Big Mac Sauce in advance?

Absolutely! In fact, Big Mac Sauce only gets better with time. Make it a day or two ahead for the best flavor and keep it refrigerated until ready to serve.
Is there a substitute for French salad dressing?

If you don’t have French dressing, you can use a little ketchup mixed with a touch of vinegar and sugar. Russian or Catalina dressing can also work in a pinch, though the flavor will vary slightly.
Can I use dill pickle relish instead of sweet pickle relish?

Yes! Dill relish gives the Big Mac Sauce a sharper, more tart kick—try it if you prefer less sweetness, or even mix half sweet and half dill for a fun flavor twist.
How can I make this sauce vegan?

To make vegan Big Mac Sauce, simply use your favorite vegan mayonnaise and double-check that your French dressing and relish are plant-based—easy!
