ANSWER: The simple answer is yes, fresh and dried herbs can be substituted for each other in most recipes. Because dried herbs have a more intense flavor substitute them at a 1 to 3 ratio (example: If a recipe calls for three teaspoons of fresh oregano, use 1 teaspoon of dried oregano instead.)
The exception to this rule are recipes where the texture of herb is important, such as pesto sauce.
Be sure to store your dried herbs in an air-tight container away from heat and light. To ensure that they are still fresh check to see if their color is still green and not faded, and crush a few leaves to verify that the aroma is still strong. Always remember that the drying process does subtly change the taste of all herbs. So when substituting fresh and dried herbs in a recipe continually taste the food to ensure you have the perfect flavor.
