Best seed-oil-free mayonnaise
Mayonnaise made without seed oils uses olive or avocado oil as the base instead of rapeseed or sunflower. Expect a stronger, more peppery flavour from olive versions and a neutral one from avocado — and a price two to three times higher per jar.
What matters when you're choosing
- Check the ingredients order: many "olive oil" mayos are mostly rapeseed with a splash of olive.
- Avocado-oil mayo is the neutral option if olive flavour overwhelms sandwiches.
- Homemade with a stick blender takes two minutes and costs a fraction as much.

Common questions
Are seed oils in mayonnaise bad for you?
UK dietary guidance does not single out seed oils as harmful. People avoid them for taste, omega balance or personal preference rather than official advice.
Which oil makes the best mayonnaise?
Light olive oil or avocado oil for a clean flavour. Extra virgin olive oil can turn bitter when emulsified at speed.
