As soon as temps warm up, all we want is a good burger. And nothing makes a burger better than a good sauce – especially a classic Big Mac sauce that hits every note (we dare you not to have the jingle in your head right now). We make this on repeat all summer long for sliders, grilled burgers, salads, and pretty much anything else we can turn into a burger.
The version we landed on uses jalapeño relish instead of just dill – same tangy backbone, just a little heat that makes it our own. The overnight rest is non-negotiable. The vinegar mellows, the spices bloom, and what starts as a good sauce turns into a great one. Make a jar on Sunday and it’s gone by Friday.
Ingredients for Homemade Big Mac Sauce
- Mayonnaise
- Pickle relish: we use jalapeño relish for a mild kick; dill relish works and is more classic – either way, chop it fine so you’re not getting big chunks in the sauce
- Classic yellow mustard: not Dijon, not spicy brown – basic yellow mustard
- White vinegar
- Sugar: just enough to balance the acid. We use monkfruit sweetener to keep it keto
- Paprika
- Onion powder and garlic powder
How to Make Homemade Big Mac Sauce
- Add the mayonnaise, pickle relish, mustard, white vinegar, sugar, paprika, onion powder, and garlic powder to a bowl.
- Stir until fully combined and smooth – no streaks of mustard, no dry spice pockets.
- Refrigerate for at least 30 minutes before serving. The sauce needs time to come together. Overnight is better. The vinegar mellows, the spices bloom, and it goes from good to great.
Substitutions
- Jalapeño relish → dill relish: more classic, slightly less heat — both work
- Dill relish → sweet relish: changes the profile significantly toward Thousand Island territory; not our preference but not wrong
- Yellow mustard → spicy brown: adds heat, works; Dijon shifts the flavor enough to move this away from the Big Mac direction
- White vinegar → apple cider vinegar: slightly fruitier, still works in a pinch
- Full-fat mayo → light mayo: thinner sauce, less richness — it’ll do but you’ll notice
💡 Meat Nerd Tips
- Make it the day before. Thirty minutes gets you a good sauce. Twenty-four hours gets you a great one. If you’re serving this at a cookout, make the jar the night before and don’t even taste it fresh; just let it do its thing in the fridge overnight.
- Chop the relish fine. If your relish has large chunks, run a knife through it before it goes in. Big pickle pieces in the sauce means uneven bites – some with too much crunch, some with none.
- Double the batch. This lasts for a week and goes on everything. There is no reason to make a single batch. Make the full jar, label it, and work through it on burgers, sliders, grain bowls, and anything else that needs a sauce.
What to Serve with Homemade Big Mac Sauce
- Big Mac Cheeseburger Sliders – the original reason we developed this sauce; it’s what takes them from really good sliders to the real thing
- Grilled burgers (including homemade Big Macs): smear it on both buns before the patty goes on
- Grain bowls and burger salads: use it as a dressing (it holds up better than you’d expect)
- Crispy fries – obviously
Leftovers and Storage
- Store in an airtight jar or container in the refrigerator for up to 1 week
- Stir before each use (the ingredients can separate slightly as it sits)

FAQs
Mayonnaise, pickle relish, yellow mustard, white vinegar, sugar, paprika, onion powder, and garlic powder. It’s closer to Thousand Island than most people expect — creamy, tangy, and slightly sweet with a pickle backbone.
Up to one week in an airtight container in the refrigerator. It actually gets better after the first 24 hours as the flavors come together.
You can, but it pushes the sauce toward Thousand Island territory. Dill relish keeps it closer to the original. Our preference is jalapeño relish – same tangy backbone, mild heat.
Grilled burgers, sliders, fries, grain bowls, burger salads, wraps. It works anywhere a creamy, tangy sauce would taste great.
