Find a very large canning jar or use a purchased herb saver. Make sure the jar is large enough that the parsley stems won’t be squished or packed inside. Place a few inches of water inside (or fill up to the water line in the herb saver).
Place the herb stems inside the jar, with the cut side in the water. (Cut off the ends if necessary to fit them in the jar.)
Screw on the lid of the jar or add the top of the herb saver. Store refrigerated for up to 1 week (or more, if using the herb saver).
Notes
*We recommend using an herb saver for best results.
