Common swaps
- These dry well and keep most of their character, so the 3 to 1 rule holds up.
- This is practical guidance, not a fixed rule. How strong dried herbs taste depends on how long they have been in the cupboard.
- Add dried herbs early so they soften and release flavour into the cooking. Add fresh herbs at the very end.
- Start with slightly less than the conversion says and taste. You can add more; you cannot take it out.

Reference and detail
Three to one, roughly
Drying removes water and concentrates what is left, so a tablespoon of chopped fresh herbs is about a teaspoon of dried. Hardy herbs like rosemary, thyme, oregano and sage hold up to this well, which is why the rule is quoted so often.
Soft herbs are not really interchangeable
Basil, parsley, coriander, chives and dill lose most of their character when dried. Dried basil in a tomato sauce is fine; dried coriander scattered over a curry at the end is not the same dish. Where a soft herb is the point of the recipe, use fresh or change the plan.
When to add them
Dried herbs need time and moisture to give up their flavour, so add them early with the onions or the liquid. Fresh herbs lose theirs to heat, so add them at the very end or off the heat entirely.
Questions and answers
Questions about substituting fresh and dried herbs
What's the general ratio between fresh and dried herbs?
Drying concentrates flavour by removing water, so roughly a tablespoon of chopped fresh herb equals a teaspoon of dried. Enter your herb and amount above for the exact figure, since hardy and soft herbs behave differently.
Can I substitute dried basil or parsley for fresh and expect the same result?
Not really. Soft herbs like basil, parsley, coriander, chives and dill lose most of their character when dried, so a dried version works in a simmered sauce but not as a fresh finishing garnish. Hardy herbs such as rosemary, thyme, oregano and sage hold up much better to drying.
Should dried herbs go in at the same point in cooking as fresh ones?
No, dried herbs need time and moisture to release their flavour, so add them early, with the onions or the liquid. Fresh herbs lose their flavour to prolonged heat, so add them at the end or off the heat.
