The taste of Chervil and Basil are the two herbs closest to that of Parsley and would work as the perfect substitute for it in dishes that have a prominent parsley flavor. Two generous bunches of chervil should serve well for your pasta. A handful of basil, same as the required amount of parsley, would not dissolve into the butter when baked for garlic bread and produce its known savory aroma once it’s ready to be served.
