Fresh to Dried Herb Conversion Calculator
| Herb | Fresh, chopped | Dried, same punch | Add it |
|---|---|---|---|
| Basil | 1 tablespoon | 1 teaspoon | early - dried basil needs the simmer |
| Oregano | 1 tablespoon | 1 teaspoon | early - a sauce herb dried |
| Thyme | 1 tablespoon | 1 teaspoon | early - woody stems out before serving |
| Rosemary | 1 tablespoon | 1 teaspoon | early - the needles need the braise |
| Sage | 1 tablespoon | 1 teaspoon | early - crisp it in the fat instead |
| Parsley | 1 tablespoon | 1 teaspoon | honestly, use fresh - dried parsley is color |
Enter the amount the recipe calls for and pick the direction. The calculator applies the standing 3-to-1 rule - one tablespoon chopped fresh, one teaspoon dried - and tells you when in the cooking to add it.
The ratio is the easy half; the timing is the half recipes skip. Dried herbs need the simmer to bloom in fat and liquid, so they go in early. Fresh herbs are volatile oils that die in the pot, so they go on at the finish. Same plant, opposite choreography - and the calculator carries both.
How to use

- Chop the fresh herb before measuring: a tablespoon of loose whole leaves is half a tablespoon of chopped.
- Dried herbs are potent for about a year; the jar from three winters ago is a spice-shaped memory. Updates live.
Frequently asked questions
What is the fresh to dried herb ratio?
Three to one: one tablespoon of chopped fresh herb equals one teaspoon of dried. It holds across basil, oregano, thyme, rosemary and sage; the calculator converts either direction at your amounts.
Can I substitute dried parsley for fresh?
You can, and it is mostly a gesture: dried parsley keeps its color but loses nearly all its flavor. Use it for appearance in a long simmer, and finish the dish with fresh parsley or simply nothing - the calculator prices the swap honestly.
When should I add dried herbs to a recipe?
Early: dried herbs need 15 to 20 minutes of simmering in fat or liquid to release, which is why they go in with the tomatoes or the braise. Adding dried herbs at the end is how dishes get a dusty, tea-like edge.
Why do dried herbs taste stronger?
Drying removes the water and concentrates the oils: the same spoonful of dried leaf carries roughly three times the aromatic load of fresh. It is a shrinkage story, not a potency story - which is exactly why the swap is three to one.
How long do dried herbs last?
About a year at full strength in a closed jar away from heat and light. The sniff test beats the calendar: if the jar smells like nothing dry, it seasons like nothing either - replace it and write the purchase date on the label.
