Substitutions / mayonnaise
What to use instead of mayonnaise
Use greek yogurt in equal amounts. Tangier and lighter; works well in dressings and dips but thinner in texture.
Every option, best first
| Use instead | How much | What changes |
|---|---|---|
| Greek yogurt | 1:1 | Tangier and lighter; works well in dressings and dips but thinner in texture. |
| Sour cream | 1:1 | Richer tang, slightly looser; holds up well in cold dishes but won't emulsify like mayo. |
| Avocado | 1:1 | Creamy and mild, but changes the flavor noticeably and browns quickly once cut. |

A word on how to read these
A substitution is a trade, not an equivalence. The ratio gets the quantity right; the third column is the part worth reading, because it tells you what you are giving up. In a stew, most of these are invisible. In a cake — where flour, liquid, fat and leavening are in a fixed relationship — the same swap can change the crumb.

Where these came from
These substitutions were written by Gather's own kitchen model — the same one the app uses when you tap an ingredient and ask what else would work — then checked and saved as a fixed list in July 2026. Nothing on this page is generated while you read it. They are a good starting point and not a substitute for tasting as you go.
