Wash, shake dry, and chop. Both flat-leaf (Italian) and curly parsley freeze well, though flat-leaf has stronger flavor.
Oil cube method: Pack chopped parsley into ice cube trays, fill with olive oil, freeze, and bag. Excellent for dropping into pastas, soups, and sautéed vegetables.
Dry freeze method: Parsley holds up better to dry freezing than most tender herbs. Chop finely, spread on a parchment-lined sheet pan, freeze for 1 hour, then scrape into a freezer bag. The frozen parsley can be sprinkled directly into dishes like dried herbs — but with much better flavor.
Stem bundles: Freeze whole parsley stems in a bag for use in stock-making. Drop frozen stems directly into simmering stock.
3 to 6 months.
Use from frozen in all cases. Dry-frozen parsley can be crumbled directly over dishes as a finishing herb (it thaws almost instantly on contact with hot food).
