Big Mac Sauce Recipe (McDonald's Copycat)

Ever wonder how to make McDonald's Big Mac sauce recipe? This secret sauce is one of my favorite copycat recipes to recreate because it's made with simple ingredients like mayo, sweet pickle relish, and ketchup. Use it as a dipping sauce for french fries or spread on your favorite sandwiches or cheeseburgers.

Whenever a fast-food burger craving hits my family, we reach for this big mac sauce recipe. It tastes just like the original big mac sauce we all know and love. 

This delicious sauce is also great as a salad dressing. Have you ever heard of a Big Mac Salad? This was popular when everyone was trying the keto diet. You just top some romaine lettuce with a burger patty along with some cheddar cheese, dill pickles, a drizzle of yellow mustard, and this homemade sauce. Tastes just like a fast food burger without the carbs from the bun.

But if you don't worry about eating low carb, go ahead and have your homemade burgers with a sesame seed bun and a side of onion rings, french fries, or tater crowns.

Mayo- gives the sauce that creamy texture and mouthfeel. Avocado oil mayonnaise can be used instead. If you want to cut back on some of the fat, try it with a low fat mayo. 

Sweet pickle relish (or dill pickle relish) can be used interchangeably. Use what you have on hand or prefer.

Ketchup or French dressing - another ingredient that I think can be used interchangeably. French dressing will give a tangier flavor. Sugar-free ketchup is also a great alternative if a low carb version is needed. It has fewer grams of sugar than regular.

Minced onions - be sure to dice very fine so the flavor will blend throughout without any big chunks. I always use yellow onions in my cooking, but red onions are also good. If you don't want to add fresh, minced onions, try a mixture of onion powder and garlic powder instead.

White vinegar - helps balance the creaminess. Sub with apple cider vinegar, white wine vinegar, lemon juice, 

Sugar - you can leave this out if using sweet relish or if you don't want any added sugar.

Instructions

Step One: Combine all ingredient in a small bowl.

Step Two: Mix well until smooth using a whisk.

If you prefer a smoother texture, mix in a blender or food processor.

Keep in a covered container until ready to use.

Top tips

Tastes best when it's had a couple hours in the fridge. Plan to make the sauce ahead of time.

Leftovers last a long time. Store leftover sauce in the fridge in an airtight container for two or three weeks.

A glass jar or container works best so there's no transfer of flavors.
