Mayonnaise is the default dressing for plenty of salads, but it’s far from the only option, and not always the best one. It’s fairly calorie-dense thanks to all that oil, and its flavor can easily overpower more delicate ingredients. Fortunately, there are plenty of solid alternatives, each suited to a different style of salad — from vegetable-forward to protein-heavy.

Yogurt and sour cream — the easiest swap

Plain, unsweetened yogurt is probably the most versatile mayo substitute out there. It offers a similar creamy texture but with noticeably fewer calories and a pleasant tang. For a richer result, go for thick yogurt (Greek-style works especially well) — it holds the dressing’s consistency better and won’t turn the salad watery. Sour cream works similarly but is a bit richer than yogurt and adds a softer, more buttery note — a good match for salads with boiled vegetables or fish.

Both pair well with fresh herbs, garlic, mustard, or lemon juice, which help nudge the flavor closer to the mayo profile people expect.

Avocado-based sauces

Mashed avocado makes a great dairy-free, egg-free base for a creamy dressing. Blended with lemon juice (to keep it from browning), a little olive oil, and seasonings, it produces a thick, rich texture close to mayonnaise, but built on healthy monounsaturated fats instead of mostly refined oil. This sauce works especially well in chicken, egg, or tuna salads, where you want a dressing with real body to it.

Tahini and nut butters

Sesame tahini, thinned with lemon juice and water to the right consistency, makes a nutty, faintly bitter dressing — an interesting choice for salads with roasted or raw vegetables, especially ones with a Middle Eastern lean. Nut butters, like cashews soaked in water and blended smooth, work in a similar way and suit anyone avoiding dairy.

Mustard and vinaigrette-style dressings

For lighter salads, there’s no real need to chase a creamy mayo substitute at all — a classic vinaigrette of olive oil, vinegar or lemon juice, and Dijon mustard works with almost any vegetable salad. Mustard acts as a natural emulsifier here, binding oil and acid into a smooth dressing, and the overall flavor ends up brighter and lighter than mayonnaise.

Hummus as a dressing

Hummus, thinned with a little water or lemon juice to a sauce-like consistency, is an underrated but genuinely convenient mayo swap. It already contains tahini, garlic, and seasoning, so the dressing comes out full-flavored with almost no extra effort. It works particularly well with grilled or roasted vegetable salads.

Choosing the right swap for the salad

The best substitute really depends on the salad itself. For light vegetable salads, an oil-and-vinegar dressing works best — it won’t weigh down delicate flavors. For salads where mayonnaise traditionally provides the structure (think classic potato salad, coleslaw, or chicken and egg salads), yogurt, sour cream, or an avocado-based sauce come closest to the original texture. And for salads with a Middle Eastern or Mediterranean lean, tahini or hummus fit naturally into the overall flavor profile.
