STEP 1: Combine Ingredients – Add the mayonnaise, yellow mustard, sweet pickle relish, white vinegar, paprika, garlic powder, and onion powder to a mason jar or small mixing bowl.
STEP 2: Stir & Rest – Stir until everything is smooth and fully combined. Cover and refrigerate for at least 30 minutes before serving. This resting time allows the flavors to blend together and creates the best flavor. Enjoy!
Substitutions & Variations
- Swap the vinegar. Apple cider vinegar or white wine vinegar both work well if that’s what you have on hand.
- Lighten it up. Replace part of the mayonnaise with plain Greek yogurt for a lighter version.
- Add heat. Stir in a dash of cayenne pepper or hot sauce for a spicy kick.
- Make it extra smoky. Use smoked paprika instead of regular paprika.
- Prefer more sweetness? Add a little extra sweet pickle relish to taste.
Big Mac Sauce Cooking Tips
- Let the sauce chill for at least 30 minutes before serving. The flavor becomes much better after resting.
- Stir well so the spices are evenly distributed throughout the creamy base.
- Taste before serving and adjust with a little extra mustard or relish to suit your preferences.
- Use a mason jar with a lid for easy mixing, storing, and serving.
- Double the recipe if you’re serving burgers at a cookout or meal prepping for the week.
- For the smoothest consistency, use finely chopped sweet pickle relish.
Storage & Make Ahead Tips
- Storage: Store your homemade Big Mac sauce in an airtight container or sealed mason jar in the refrigerator for up to 1 week.
- Make Ahead Tips: This is an excellent make-ahead recipe because the flavor actually improves after several hours in the refrigerator as the seasonings have time to meld together.
- Freezing: Because this Copycat Big Mac Sauceis mayonnaise-based, freezing can cause the emulsion to break. Once thawed, the sauce will become watery, grainy, or separated, and stirring it back together usually won’t restore its original creamy texture. So I do not recommend freezing this sauce.
