I used to think burger sauce was just ketchup and mayo stirred together in a bowl.
It kind of is. But it also really isn’t, because the first few times I made it, it came out tasting like… ketchup and mayo. Fine. Forgettable. The sauce equivalent of a shrug.
What actually turned it around was a piece of onion. Not onion powder — a real one, grated on the small holes of a box grater and squeezed dry in a paper towel. That one change took my burger sauce from “yeah, okay” to the thing my husband asks about by name before I’ve even started the burgers.
This burger sauce recipe takes about five minutes and uses stuff you almost certainly have. I’m also giving you the ratio I use so you can scale it, tweak it, and stop measuring entirely once you’ve made it a couple of times. That’s the part nobody hands you.

Why You’ll Love This Recipe
- Five minutes, one bowl, one whisk (or a fork, honestly)
- No cooking, no blender, nothing to clean up
- Pantry ingredients you already have
- Tastes better than the bottled stuff and costs about a dollar
- Works on burgers, fries, chicken sandwiches, and straight off a spoon
Also, once you know the ratio, you can make it without a recipe. Which is the actual goal here.
Ingredients You’ll Need
½ cup mayonnaise – The base, and it’s doing most of the work. Use a full-fat one you actually like the taste of, because you’re going to taste it.
3 tbsp ketchup – This is the sweet, tangy, tomato part. Three tablespoons is my number. Two is subtle, four starts tasting like a kid’s dipping sauce.
2 tbsp dill pickle relish – Not sweet relish. Dill. You want the sharpness fighting the ketchup, not agreeing with it.
1 tbsp yellow mustard – Plain old yellow. Dijon is nice but it makes the sauce taste fancy, and burger sauce should not taste fancy.
1 tbsp finely grated yellow onion, squeezed dry – Here’s the one that matters. Grate it on the small holes, then wring it out in a paper towel until it stops dripping. It gives you a fresh allium bite that onion powder simply cannot do. (More on the squeezing below, because it matters more than it sounds like it should.)
2 tsp pickle brine – Straight from the jar. This thins the sauce slightly and layers in a second kind of sour. Free flavor.
1 tsp Worcestershire sauce – Savory depth. You won’t taste it as Worcestershire, you’ll just notice the sauce tastes like more than the sum of its parts.
½ tsp garlic powder – Powder, not fresh. Fresh garlic in a cold sauce gets harsh and takes over.
½ tsp smoked paprika – For warmth and a little color. It’s what makes the sauce look orange-pink instead of sad pink.
¼ tsp black pepper – Yes.
Salt, to taste – Start with a pinch. The ketchup, pickles, mustard, and Worcestershire are all salty already, so taste before you commit.
How to Make This Recipe
Grate the onion first, because it’s the only step that takes any effort.
Use the small holes on a box grater and go until you have about a tablespoon of onion pulp. Pile it into a paper towel, gather up the corners, and squeeze over the sink until the liquid stops running. It’ll look like a sad little onion nugget. That’s correct.
Put the mayo in a medium bowl. Add the ketchup, relish, mustard, squeezed onion, pickle brine, Worcestershire, garlic powder, smoked paprika, and pepper.
Whisk it all together until it’s one smooth, even color with no ketchup streaks running through it. Takes about thirty seconds.
Taste it. Now add salt if it needs it, and adjust from there — more ketchup for sweetness, more brine or mustard for tang, more paprika for depth.
Cover it and put it in the fridge for at least 30 minutes before serving if you can. It’s good right away, but the garlic powder needs a little time to stop tasting like garlic powder and start tasting like the sauce.

Notes
My “8-3-2-1” Mini Guide
This is the part I wish someone had told me years ago. Burger sauce isn’t a recipe, it’s a ratio — and once you know it, you’ll never measure again.
The formula, in tablespoons:
- 8 mayo
- 3 ketchup
- 2 dill relish
- 1 yellow mustard
That’s it. Eight, three, two, one. Everything else — the onion, brine, Worcestershire, garlic powder, paprika — is seasoning layered on top, roughly ½ to 1 teaspoon each per ½ cup of mayo.
Want to double it for a cookout? 16-6-4-2. Making a tiny batch for two burgers? 4-1.5-1-0.5. The proportions hold.
A few things I’ve learned working with that ratio:
- Squeeze the onion or the sauce will break. Onion is mostly water, and that water thins mayo into something runny that slides off the bun. Squeeze it until it’s genuinely dry. You’ll be surprised how much comes out.
- Push the ketchup up, not the mayo down. If it tastes flat, people instinctively add more mayo. Don’t. Mayo mutes things. Add ketchup or brine instead.
- Fresh onion is a same-week ingredient. This is the honest tradeoff nobody mentions. Raw grated onion keeps developing its sulfur compounds in the fridge, so a sauce that’s bright and fresh on day one gets noticeably sharper by day three or four. Great for a weekend. Not great for a big make-ahead batch.
- So: grate for now, powder for later. If you’re making sauce for tonight or tomorrow, use the fresh grated onion — it’s the whole reason this tastes better than the bottle. If you’re batching a jar to keep for a week or two, swap in ½ tsp onion powder instead and it’ll stay stable and even the whole time.
- Let it sit if you can. Thirty minutes minimum, a couple of hours is better. Everything softens into one flavor instead of several.
Burger Sauce vs. Big Mac Sauce vs. Fry Sauce
These all get used interchangeably online and they’re genuinely not the same thing.
Fry sauce is the simplest — mayo and ketchup, roughly 2:1, and that’s basically it. It’s a dip, not a burger sauce.
Big Mac sauce (or copycat versions of it) leans sweet. It uses sweet pickle relish, often a little sugar or French dressing, and skips the vinegar sharpness. That’s why it tastes distinctly fast-food.
Thousand Island is a salad dressing first. It’s usually thinner, sweeter, and frequently has hard-boiled egg or chili sauce in it.
This burger sauce sits between them: mayo-forward like fry sauce, but with dill relish, mustard, brine, and Worcestershire doing tangy-savory work that the sweeter sauces don’t. It’s built to cut through beef fat rather than sit politely next to it.
Helpful Tips
Figure on about 2 tablespoons per burger. This recipe makes roughly ¾ cup, so it’ll comfortably sauce six burgers with a little left for fries.
Make it a day ahead for a cookout — just use the onion powder version so it holds. Working backward from the number of burgers is easier than guessing: six burgers, one batch.
For a vegan version, swap in vegan mayo and check your Worcestershire (most contain anchovy). Everything else is already plant-based.
If it’s too thick for dipping, add pickle brine a teaspoon at a time rather than water. Water dilutes flavor; brine adds it.
It’s excellent on things that aren’t burgers. Sweet potato fries, crispy chicken sandwiches, onion rings. I’ve put it on a cheeseburger pasta situation and have no regrets.
Frequently Asked Questions
How long does burger sauce last in the fridge?
About a week in an airtight container if you used onion powder, and closer to three or four days with fresh grated onion before it starts turning sharp. Always store it cold.
Can I freeze burger sauce?
Technically yes, but I wouldn’t. Mayonnaise-based sauces split when they thaw — the oil separates and the texture goes grainy and weepy. It takes five minutes to make fresh, so freezing solves a problem you don’t have.
Can I use sweet relish instead of dill?
You can, and you’ll get something much closer to a Big Mac-style sauce. If you go that route, cut the ketchup back to 2 tablespoons or the whole thing tips too sweet.
Do I have to grate the onion?
No. Half a teaspoon of onion powder works and keeps better. But the grated onion is the single biggest reason this tastes homemade instead of bottled, so try it once.
My sauce is runny. What happened?
Almost always under-squeezed onion. Onion is mostly water and it keeps releasing it into the sauce as it sits. Squeeze harder next time, and in the meantime, a spoonful more mayo will pull it back together.
Final Thoughts
Burger sauce is one of those things that takes five minutes and makes people think you did something clever.
You didn’t. You grated an onion and stirred a bowl.
But once you’ve got 8-3-2-1 in your head, you’ll stop buying the bottled stuff, and you’ll start making it for things that aren’t even burgers.
Which is exactly how it should go, honestly.
