The best mayonnaise substitute is plain Greek yogurt, used one to one, which adds creaminess with a tangy flavor and less fat. Sour cream, mashed avocado, hummus and mustard also work, depending on the dish. Choose based on whether you want a spread, a binder for salads, or a base for dressing.
Swap mayonnaise 1 to 1 with Greek yogurt or sour cream. Mashed avocado or hummus also work as spreads.

Match to the Use
For a sandwich spread, avocado or hummus work well. For binding tuna, egg or potato salad, Greek yogurt or sour cream keep it creamy. In dressings, yogurt gives a lighter result. For a similar swap, see the sour cream substitute. Store leftovers sealed in a container.
