Copycat Big Mac Sauce Recipe

There’s something incredibly nostalgic about the taste of a Big Mac — and if we’re being honest, it’s not really the burger itself that steals the show.

It’s that creamy, tangy, just-a-little-sweet Big Mac sauce that keeps us coming back. If you’ve ever found yourself wishing you could bottle it up and drizzle it on everything, good news: you absolutely can, and right in your kitchen!

For years, people have been trying to decode the secret behind McDonald’s famous sauce. Some swore it was just Thousand Island dressing (spoiler alert: it’s not). Others tried mixing random condiments, hoping to strike gold.

But after a little digging and a lot of taste-testing, the perfect copycat recipe is here — and it tastes so close to the real thing, you might never need the drive-thru again.

What I love most about this Big Mac sauce is how ridiculously versatile it is. Sure, it’s perfect for burgers, but it also makes a killer dip for fries, adds magic to sandwiches, and even works as a salad dressing if you’re feeling fancy. Plus, it uses simple ingredients you probably already have sitting in your fridge or pantry.

Whether you’re planning a backyard cookout or just craving a McDonald’s fix without the fast food run, this Big Mac sauce recipe is going to be your new favorite secret weapon.

Ingredient List

• 1/2 cup mayonnaise
• 2 tablespoons sweet pickle relish
• 1 tablespoon yellow mustard
• 1 teaspoon white vinegar
• 1 teaspoon onion powder
• 1 teaspoon garlic powder
• 1/2 teaspoon smoked paprika
• 1/2 teaspoon sugar (optional, for a slightly sweeter touch)

---

Ingredient Notes

• Mayonnaise – Use a creamy, full-fat mayo like Hellmann’s or Duke’s for that rich, classic base.
• Sweet Pickle Relish – This gives the sauce its signature tang and tiny bursts of sweetness — don’t swap it for dill relish unless you want a different flavor.
• Yellow Mustard – Classic yellow mustard adds a little zip; avoid Dijon or spicy brown here.
• Smoked Paprika – Adds depth and a mild smokiness — regular paprika works, but smoked elevates it.
• White Vinegar – Just a splash brightens everything up; apple cider vinegar could work in a pinch.
• Sugar – Totally optional, but just half a teaspoon can round out the flavors beautifully.

Kitchen Equipment Needed

• Mixing Bowl – For combining all the ingredients; I like using a glass one so I can see the color and texture better.
• Whisk or Spoon – A small whisk works best to blend everything smoothly, but a sturdy spoon gets the job done too.
• Measuring Spoons – For getting those spices just right — I swear by magnetic ones that stick together in the drawer.
• Airtight Container or Jar – For storing the sauce in the fridge, mason jars are my go-to for easy scooping and zero spills.

Instructions

Step 1: Measure Out Your Ingredients

• Start by laying out all your ingredients so they’re within reach — this makes the process smoother.
• Use your measuring spoons and cups to get accurate amounts. This sauce is all about balance, so no eyeballing!

Pro Tip: Level off the spices with the back of a knife to avoid overdoing it. A little too much garlic or paprika can overpower the sauce.

---

Step 2: Combine the Base

• In a medium mixing bowl, add 1/2 cup of mayonnaise as your creamy base.
• Add in 2 tablespoons of sweet pickle relish and 1 tablespoon of yellow mustard.

Pro Tip: Use a silicone spatula to scrape every bit of mayo from the measuring cup — waste nothing!

---

Step 3: Add Seasonings

• Sprinkle in 1 teaspoon each of onion powder and garlic powder.
• Add 1/2 teaspoon of smoked paprika and 1/2 teaspoon of sugar (if using).
• Finish with 1 teaspoon of white vinegar to brighten it all up.

---

Step 4: Mix Until Smooth

• Using a small whisk or spoon, mix everything until the sauce is smooth, creamy, and well-blended.
• Be sure to scrape along the sides and bottom of the bowl so nothing is left unmixed.

Pro Tip: Whisk in a slow circular motion at first, then speed up — this helps prevent any clumping from the dry spices.

---

Step 5: Chill for Maximum Flavor

• Transfer the sauce to a clean airtight container or jar.
• Pop it in the fridge for at least 30 minutes to let the flavors mingle and deepen.

Pro Tip: Overnight is even better — the sauce thickens a bit and tastes more like the real deal after a good rest.

Tips and Tricks for Success

• Let it chill – Always give the sauce time in the fridge before serving. Even 30 minutes makes a huge difference in flavor.
• Taste and tweak – Everyone’s taste buds are different, so feel free to adjust the sweetness, tanginess, or spice to your liking.
• Use quality mayo – The better the mayo, the better the sauce. This isn’t the time for low-fat or flavored versions.
• Mix thoroughly – Make sure all the seasonings are well incorporated so every bite has that signature Big Mac taste.
• Double the batch – It keeps well, and you’ll definitely want extra for dipping fries or spreading on sandwiches later.

Ingredient Substitutions and Variations

• No sweet pickle relish? – Try finely chopping bread and butter pickles for a similar sweet-tangy effect.
• Want it spicier? – Add a pinch of cayenne or a squirt of sriracha to kick up the heat.
• No smoked paprika? – Regular paprika works too, but you’ll miss that subtle smokiness.
• Need it dairy-free? – Just make sure your mayo is plant-based — the rest of the ingredients are already dairy-free.
• Prefer a smoother texture? – Blend the sauce in a small food processor to make it extra creamy, especially if using chunkier relish.

Serving Suggestions

• Classic Burgers – Of course, this is a must! Spread a generous layer on burger buns and top with lettuce, cheese, pickles, and a beef patty for that full Big Mac experience.
• Dip for Fries or Nuggets – Skip the ketchup and dip your fries or chicken nuggets into this sauce — it’s next-level good.
• Sandwich or Wrap Spread – Add flavor to deli sandwiches, wraps, or even breakfast bagels. It adds just the right zing.
• Loaded Fries or Nachos – Drizzle over loaded fries or cheeseburger-style nachos for a fast food twist at home.
• My Favorite Use? – I love using it in homemade cheeseburger bowls with lettuce, tomatoes, pickles, seasoned ground beef, and this sauce on top — it’s like a fast food fix in a healthier package!

Storage and Reheating Instructions

• Store in an airtight container – A mason jar or any sealed container works great to keep the sauce fresh.
• Keep refrigerated – Always store it in the fridge; it should last about 1 week.
• Stir before using – Ingredients may settle over time, so give it a good stir each time you scoop it out.
• No reheating needed – This is a cold sauce and doesn’t need to be heated. Just bring it to room temperature for a few minutes if it feels too thick straight from the fridge.
• Freeze? Not recommended – The mayo base doesn’t freeze well and can separate when thawed, so just make a fresh batch when needed.

Frequently Asked Questions

Can I use dill relish instead of sweet pickle relish?
Yes, but it’ll change the flavor quite a bit. Dill relish makes it more tangy and less sweet, so expect a slightly different vibe.

Is this the exact McDonald’s recipe?
Not exactly — McDonald’s keeps the original recipe under wraps. But this version comes seriously close and satisfies the same craving!

How long does Big Mac sauce last in the fridge?
About a week when stored in an airtight container. Just be sure to use clean utensils each time to keep it fresh.

Can I make it vegan?
Totally! Just swap the mayo for a vegan-friendly brand — everything else is plant-based.

Why does mine taste different than McDonald’s?
It could be the mayo or relish brand you used, or not letting the sauce chill long enough. Try tweaking the sweetness or tang to match your taste memory.

Can I use this as a salad dressing?
Absolutely — it’s fantastic on burger salads or even a classic wedge salad for a fun twist.
