Fresh to Dried Herb Converter
Convert fresh herbs to dried or dried to fresh with the standard 3-to-1 ratio — 1 tablespoon of fresh chopped herbs equals about 1 teaspoon dried.
How it works
Dried = fresh ÷ 3 · Fresh = dried × 3 (leafy herbs, by volume)
Drying removes the water from herbs and concentrates their essential oils, so a small amount of dried herb carries the flavor of a much larger volume of fresh. The reliable rule of thumb for leafy herbs is 3:1 — one tablespoon of fresh chopped herb equals about one teaspoon of dried. Finely ground dried herbs are more potent again, closer to 4:1, and timing differs: dried herbs need heat and time to bloom, while delicate fresh herbs are best stirred in near the end.
Worked example
A sauce calls for 1 tablespoon of fresh basil but you only have dried. Convert to teaspoons (1 tbsp = 3 tsp) and divide by 3 to get 1 teaspoon of dried basil, added early so it has time to rehydrate and release flavor.
Frequently asked questions
Is the 3:1 ratio the same for every herb?
It works well for most leafy herbs like basil, oregano, parsley, thyme and dill. Very potent or ground herbs (rosemary ground fine, or dried herbs sold as powder) can be closer to 4:1, so start with a little less and taste before adding more.
When should I add dried versus fresh herbs?
Add dried herbs early in cooking so heat and moisture can draw out their oils. Add tender fresh herbs — basil, cilantro, parsley — in the last minute or two, since their flavor and color fade quickly with heat.
Does this ratio apply to spices too?
No, this is specifically for the fresh-versus-dried form of leafy herbs. Converting whole spices to ground, or fresh aromatics like garlic and ginger to powders, uses different ratios.
