Mayonnaise substitutes
Mayonnaise is an oil-in-water emulsion stabilized by egg yolk lecithin, contributing fat, moisture, a mild tangy richness, and binding power to recipes. In baking it keeps cakes and quick breads tender by coating gluten strands with fat and adding emulsified moisture. As a spread or dressing base it provides body, cling, and a creamy mouthfeel that thinner substitutes can't fully replicate.

| Rank | Substitute | Ratio (replaces 1 cup Mayonnaise) | Notes |
|---|---|---|---|
| #1 | Greek yogurt | 1:1 (e.g., 1/4 cup Greek yogurt for 1/4 cup mayonnaise) | Full-fat Greek yogurt is the most widely recommended swap — it matches mayo's thick, creamy body and mild tang better than any other single ingredient, though it reads slightly more sour and lacks the fat richness; use full-fat only, as low-fat versions turn watery. |
| #2 | Sour cream | 1:1 (e.g., 1/2 cup sour cream for 1/2 cup mayonnaise) | Sour cream mirrors mayo's fat content and creamy texture closely, making it the best option for dips, dressings, and cold salads where richness matters; flavor is tangier and more dairy-forward, which is noticeable in simple preparations like coleslaw. |
| #3 | Plain whole-milk yogurt | 1:1, strained through cheesecloth for 30 minutes to remove excess whey before measuring | Unstrained yogurt is too thin and will make dressings runny and baked goods gummy — straining is non-negotiable; once strained, it performs similarly to Greek yogurt but with a slightly thinner body. |
| #4 | Silken tofu blended with lemon juice and neutral oil | 3/4 cup silken tofu + 1 tbsp lemon juice + 1 tbsp neutral oil, blended until completely smooth, for every 3/4 cup mayonnaise | The most reliable dairy-free and egg-free substitute for cold applications like sandwich spreads and dressings; texture is slightly less stable and flavor is notably blander, requiring seasoning adjustment — it breaks down noticeably if heated. |
| #5 | Vegan mayonnaise (store-bought) | 1:1 | Products like Hellmann's Vegan or Just Mayo use modified starch and pea protein to approximate emulsion structure — performance in baking and as a spread is the closest to regular mayo of any substitute, but flavor varies by brand and is generally less rich; works in a pinch but noticeably different in taste-forward applications. |
| #6 | Cream cheese thinned with milk | 3 tbsp cream cheese + 1 tbsp whole milk, softened and whisked smooth, for every 1/4 cup mayonnaise | Works acceptably in thick dips and as a spread, but is denser than mayo, not suitable for dressings requiring pourable body, and contributes a distinct dairy tang; do not use in baking, as the fat composition behaves differently and can affect rise and crumb. |
When to be careful
Mayonnaise's specific emulsion structure is critical in grilled or baked applications where it forms a browning, protective crust on proteins (e.g., mayo-coated grilled chicken) — water-heavy substitutes like yogurt will steam rather than brown and can cause sticking. In classic cold-set dishes like a traditional potato salad served to a crowd, the textural and flavor difference of any substitute will be perceptible.
Why these substitutes work
Mayonnaise is a stable oil-in-water emulsion: egg yolk lecithin molecules have one end attracted to water and one to fat, surrounding droplets of oil and preventing them from coalescing. This emulsion delivers fat-soluble flavor compounds, provides lubricity and cling, and in baking coats gluten proteins to shorten their structure for a tender crumb. Substitutes that approximate this fat-and-emulsifier combination — like Greek yogurt with its milk proteins and fat — partially replicate the functional results, but none reproduce the exact lecithin-driven emulsion, which is why texture and browning behavior always differ.
Across most everyday uses — dressings, dips, cold salads, and baking — full-fat Greek yogurt is the substitute to reach for first. It handles the widest range of applications without requiring special preparation, and its flavor profile, while tangier, is close enough that most recipes absorb the difference well. Sour cream is the better choice when richness is the priority and tartness is already balanced by other ingredients.
For dairy-free needs, store-bought vegan mayo outperforms the DIY tofu blend in most tests because its emulsion structure is engineered to mimic conventional mayo. The tofu blend is a useful backup when vegan mayo isn’t available but requires careful blending and seasoning. None of the substitutes in the table replicate mayo’s high-heat browning behavior — for that specific use case, there is no reliable workaround.
Frequently asked questions
- Can I substitute Greek yogurt for mayonnaise in a cake recipe?
- Yes, full-fat Greek yogurt works at a 1:1 ratio in most mayo-based cake recipes (such as chocolate mayo cake). The cake will be slightly less rich and very marginally more dense, but the difference is minor and the result is fully acceptable.
- Does mayo substitution work for grilling fish or chicken with a mayo coating?
- Poorly. The fat and emulsion in mayo create a protective, browning crust during high heat. Greek yogurt and sour cream contain more water and will steam rather than sear, often causing sticking. For grilling, regular mayo or store-bought vegan mayo is strongly preferred.
- Can I use olive oil-based substitutes, like just plain olive oil, instead of mayo?
- No. Plain oil lacks the emulsifying agents and water phase that give mayo its body and cling — it will make dressings greasy and separate, and will not function as a spread or binding agent. Oil alone is not a workable substitute in any mayo application.
