How to Make this

Print Recipe (No Advertisments)

1. Gather everything: 1/2 cup mayonnaise, 2 tbsp sweet pickle relish, 1 tbsp ketchup, 1 tsp yellow mustard, 1 tsp white vinegar, 1 tsp onion powder, 1/2 tsp garlic powder, 1/2 tsp paprika, 1 tsp granulated sugar, pinch salt and pinch black pepper.

2. In a medium bowl add the mayo, relish, ketchup and mustard. Give it a rough mix so the colors start to come together.

3. Add the vinegar, onion powder, garlic powder, paprika, sugar, salt and pepper. Stir well until the sugar dissolves and the mixture looks even.

4. For extra smoothness pulse the mix in a mini food processor for 5 to 10 seconds. If you like little relish bits leave it as is.

5. Taste and tweak: if it’s too sharp add a tiny pinch more sugar, if it’s flat add a few drops more vinegar, if you want more zip add a touch more mustard. Don’t overdo it, small changes go a long way.

6. Cover the bowl or put sauce in an airtight jar and chill at least 30 minutes. It’s way better after 2 to 24 hours once the flavors marry.

7. Give it a final stir before using so any separated liquid reincorporates. Use on burgers, sandwiches or as a dip.

8. Store leftover sauce in the fridge in a sealed container for up to about one week.

1/2 teaspoon garlic powder

1/2 teaspoon paprika

1 teaspoon granulated sugar

Q: Can I make this ahead of time? A: Yes, absolutely. Make it the night before for best flavor, and store in an airtight container in the fridge for up to 5 to 7 days.

Q: Can I substitute regular mayo with low fat mayo? A: You can, but the sauce won't be as rich or creamy. Full fat mayo gives the closest match to the original.

Q: What if I don't have sweet pickle relish? A: You can chop dill pickles fine and stir in a little honey or sugar to mimic the sweetness, but texture and flavor wont be exact.

Q: Is this spicy? A: No, it's mild. If you want heat add a pinch of cayenne or a dash of hot sauce.

Q: How can I make it thicker or thinner? A: Thicker: add a bit more mayo. Thinner: stir in a tiny splash of pickle juice or vinegar until you reach the texture you like.

McDonald’s Big Mac Special Sauce Recipe (Copycat Secret Sauce) Substitutions and Variations

Here’s my quick copycat Big Mac Special Sauce recipe. It’s easy, tangy and honestly pretty addicting, you’ll want it on everything.

Ingredients

1/2 cup mayonnaise
2 tablespoons sweet pickle relish
1 tablespoon ketchup
1 teaspoon yellow mustard
1 teaspoon white vinegar
1 teaspoon onion powder
1/2 teaspoon garlic powder
1/2 teaspoon paprika
1 teaspoon granulated sugar
pinch salt
pinch black pepper

Quick method
Mix everything in a small bowl and whisk until smooth. Cover and chill at least 30 minutes so the flavors meld. Want it super smooth? Toss it in a blender for 5 to 10 seconds, trust me it helps.

Substitutions

Mayonnaise: swap with plain full fat Greek yogurt 1:1 for a lighter tang, or use vegan mayo for dairy free.
Sweet pickle relish: use finely chopped bread and butter pickles, or chopped dill pickles plus 1/2 teaspoon granulated sugar to mimic the sweetness.
Ketchup: replace with tomato paste thinned with a splash of water and about 1/4 teaspoon sugar per tablespoon of ketchup to match sweetness and texture.
White vinegar: use apple cider vinegar or fresh lemon juice 1:1, same acidity but a bit fruitier.

Tip: taste after chilling and adjust sugar or vinegar by a little if it needs to be sweeter or tangier. Enjoy, it’s great on burgers fries and even as a dip.

Pro Tips

– Strain the relish or blot it with a paper towel before mixing if you dont want a runny sauce. little extra liquid will thin it fast, and you can always add a splash of vinegar later if it needs brightness.

– Taste it the way you’ll eat it, not just off a spoon. try it on a bun or a chip cause flavors change with bread or meat. tweak in tiny steps, like a pinch or 1/4 tsp at a time, small changes go further than you think.

– Want to change calories or texture? swap up to half the mayo for plain Greek yogurt for tang and less fat, or stir in chopped chives, a tiny bit of hot sauce, or smoked paprika for depth. dont overdo additions, add little by little and taste.

– Make it ahead and chill at least a couple hours, even overnight if you can, the flavors settle way better. store in a sealed jar in the fridge and dont freeze it. if it separates just stir or whisk it back together before using.
