This is a three-ingredient burger sauce — mayonnaise, lemon juice, and salt — that takes about two minutes to put together. It’s brighter and lighter than plain mayo, and it works on beef, chicken, or veggie burgers without fighting the other toppings. The honest reason to make it: you probably have everything you need in your kitchen right now.
What makes this version work
The ratio is the whole game here. Half a cup of mayo to just one tablespoon of lemon juice keeps the sauce creamy without turning it runny or sour. Too much lemon and it breaks the emulsion of the mayo, leaving you with a thin, oily mess. Mixing in a bowl rather than directly on the bun also matters — it lets the salt dissolve evenly into the sauce instead of hitting in random sharp bursts. Use fresh lemon juice if you have it; bottled juice works but has a slightly flat, one-note flavor that fresh doesn’t.
Common problems and fixes
- Sauce is too thin and slides off the bun: Your mayo was probably warm. Chill the finished sauce for 10–15 minutes before assembling — it firms back up quickly.
- Flavor tastes flat: Salt is doing more work here than it looks like. Taste the sauce after mixing and add salt in small pinches; it pulls the lemon forward noticeably.
- Too sour for your taste: Stir in a small drizzle of honey — half a teaspoon is enough to round the edge off without making the sauce sweet.
- Sauce soaks into the bottom bun: Spread it on the top bun or the patty side instead. The fat in the mayo still coats everything, but the bread holds up better.
- Looks separated after sitting: Give it a quick stir. Mayo-based sauces can weep a little liquid on the surface — it’s cosmetic, not a sign anything went wrong.
Substitutions that actually work
- Mayonnaise: Greek yogurt works as a straight swap for a tangier, lower-fat version — use full-fat yogurt or the sauce will be noticeably thinner. Skip light mayo; the water content makes it runny fast.
- Lemon juice: Lime juice is a clean substitute with a slightly sharper citrus note. White wine vinegar also works in a pinch — use about half the amount.
- Want more body: A teaspoon of Dijon mustard stirred in adds depth and helps the sauce cling to the patty better without changing the overall flavor profile much.
Make-ahead notes
This sauce keeps well in the fridge for up to five days in a sealed container — the flavor actually improves slightly after a few hours as the lemon and salt settle into the mayo. Make a double batch on Sunday and it’s ready for burgers all week with zero extra effort. It doesn’t freeze well; mayo-based sauces break when frozen and thawed, turning grainy and separated. Keep it cold until you’re ready to use it, and give it a stir if it’s been sitting for more than a day.

Common questions
Can I use store-bought mayo instead of homemade?
Yes, store-bought mayo works perfectly fine here. Homemade mayo has a slightly richer flavor, but the difference in a three-ingredient sauce this simple is small enough that it’s not worth the extra effort on a weeknight.
How much sauce does this make, and is it enough for four burgers?
Half a cup of sauce is enough for four burgers if you’re spreading it as a condiment. If you like a heavy hand with sauce or are using it as a dip for fries on the side, double the recipe — it takes no extra time.
Can I add garlic or herbs to this sauce?
Yes, and it’s a straightforward addition. A small clove of garlic grated on a microplane blends in cleanly without chunks; fresh dill or chives are the herbs that work best with lemon mayo without overpowering it.
Does this sauce work on chicken burgers?
It works well on chicken burgers — the lemon cuts through the richness of a fried or grilled chicken patty nicely. Just make sure your chicken patty is cooked to 165°F (74°C) internal temperature before saucing and serving.
