Regular mayonnaise usually contains egg and is not vegan, even if it is dairy-free. Vegan mayonnaise uses a different recipe; check the exact product and any added flavourings.
Check your own packetFor mayonnaise, start with egg rather than stopping at a dairy-free claim.
- Match Real, Light, Plant Based or Vegan wording to the product in your hand.
- Check for whole egg, yolk, milk, honey and other ingredients added to flavoured versions.
- Compare the ingredient evidence with a current vegan claim; treat allergy questions separately.

Egg is usually the ingredient that decides it
Mayonnaise can look like a dairy product without containing dairy. The classic version is an emulsion based on oil and egg, so “dairy-free” does not answer the vegan question. This is a common source of confusion on sandwich counters and in shopping searches.
Hellmann's makes the distinction explicitly in its UK FAQ: traditional mayonnaise uses egg, while its vegan alternative uses a different formula. Its Canadian FAQ also distinguishes dairy-free Real Mayonnaise from its Certified Vegan Plant Based product. Both were checked on November 1, 2026.
Scroll the table sideways to read every column.
| Example or wording | What it tells you | What still needs checking |
|---|---|---|
| Hellmann's Real Mayonnaise, Canada, 1.42 L | The published recipe contains whole egg and egg yolk. | Not vegan, regardless of a dairy-free description. |
| Hellmann's Plant Based, Canadian FAQ | The maker identifies this named product as Certified Vegan. | Match the exact jar and current market; do not transfer the claim to Real Mayonnaise. |
| Light or olive-oil mayonnaise | A fat-content or oil description. | It does not establish that egg has been removed. |
| Egg-free dressing | An absence claim about egg. | Other ingredients, including dairy or honey in a flavoured recipe, still matter. |
The named Canadian Real recipe is on Hellmann's product listing. This table is deliberately product-specific; it is not a claim that every mayonnaise bearing the brand has the same ingredients.
What changes in vegan mayonnaise?
Vegan versions replace the role of egg with other ingredients. Some recipes use aquafaba, soy or starches, but there is no single formula shared by all brands. An egg-free recipe is therefore not automatically soy-free, gluten-free or suitable for someone with another allergy.
For a home recipe, check every addition as well as the base: a honey mustard ingredient or dairy-containing flavouring can change an otherwise plant-based mixture.
Reading flavoured mayo and sandwich labels
Start with the mayonnaise itself, then the additional ingredients. A restaurant's “vegan mayo” may be a suitable condiment, while the sandwich still contains dairy cheese or a non-vegan bread. Conversely, a vegetable filling does not make an egg-based dressing vegan.
Ask a specific question: “Is the mayonnaise used in this sandwich the vegan version, and can you check the ingredient label?” That gives the staff a concrete item to identify. The same approach works with sauces on chips; see our French fries guide for the separate checks around the food itself.
Other labels that do not settle the answer
Kosher pareve is not another way to say vegan. A pareve food may contain egg, as explained in our kosher and pareve guide. Likewise, a “plant-based” phrase needs to be read in context; look for the exact ingredient list and a clear product-specific statement.
When both are available, keep the manufacturer's current vegan statement alongside the packet details. Our vegan labels and certification guide explains the difference between a claim and a certification scheme. A supermarket category or an old app record is weaker evidence than the correct current jar.
Quick questions about mayonnaise
Can mayonnaise be dairy-free but not vegan?
Yes. Egg-based mayonnaise can contain no dairy and still be non-vegan because eggs are animal-derived.
Is vegan mayo suitable for every allergy?
No. Vegan suitability does not establish allergen safety. Read the product's allergy information and seek appropriate advice for the particular allergy.
