I will repeat an answer found within the other good answers: Rule of thumb is 1 tsp dried herb substituted for 1 tablespoon fresh herb.
One fresh bunch of thyme is roughly equivalent to one teaspoon of dried thyme.
With thyme one fresh sprig equals one-half teaspoon of dried thyme. In general, use two to three times the amount of fresh thyme as dried. When adding to soups and stews, crush the leaves between your hands before stirring it in your recipe.
Generally, dried herbs are more concentrated in flavor than fresh ones. A common conversion is that 1 teaspoon of dried thyme is roughly equivalent to 3 teaspoons (or 1 tablespoon) of fresh thyme. Therefore, to substitute for 2 teaspoons of fresh thyme, you would use about 2/3 teaspoon of dried thyme.
One small sprig of rosemary converts to 1/2 a teaspoon of dried rosemary.
one and a half to two
The rule of thumb is: 1 teaspoon dried herb = 1 tablespoon fresh herb
Dried herbs are normally twice as strong as fresh, so 1/2 a tsp.
I am sorry but you can't turn dried sage int to fresh thyme...
When substituting basil for thyme, use about three times the amount of basil since basil has a milder flavor compared to thyme. For example, if a recipe calls for 1 teaspoon of dried thyme, you can use 3 teaspoons (or 1 tablespoon) of dried basil. Fresh basil can also be used; in that case, use about 1 tablespoon of fresh basil for every teaspoon of dried thyme. Adjust according to your taste preferences, as individual palates may vary.
Generally, one sprig of fresh thyme is equivalent to about 1/3 teaspoon of dried thyme. Therefore, 12 sprigs would equal approximately 4 teaspoons of dried thyme. If you prefer to measure in tablespoons, that would be about 1 tablespoon plus 1 teaspoon of dried thyme. Keep in mind that dried herbs are more concentrated in flavor than fresh ones, so adjust to taste if needed.
To add thyme to soup, you can use either fresh or dried thyme. If using fresh thyme, add a few sprigs whole during the cooking process and remove them before serving. For dried thyme, sprinkle in about half a teaspoon to a teaspoon, depending on the quantity of soup, and allow it to simmer for at least 20 minutes to fully release its flavor. Adjust the amount based on your taste preference and the soup's cooking time.
Typically, when substituting thyme powder for fresh thyme, use about one-third the amount of powder as you would fresh. Since dried herbs are more concentrated, you would need approximately 1 teaspoon of thyme powder to replace 1 tablespoon of chopped fresh thyme. Adjust to taste, as the intensity of flavor can vary.
