Persillade (Green Onion and Parsley Sauce)

Persillade is a zesty and fresh green herb sauce with parsley, green onions, garlic, and lemon. This simple parsley sauce adds a bright flavor to seafood, beef, pork, lamb, and vegetables. It pairs perfectly with rich dishes to add a necessary acidity.

French Lemon Parsley Sauce

I’m adding persillade to my Cajun recipes because of it’s French origins. French cuisine has had a huge impact on Cajun, Creole, and New Orleans cuisine. Look at the Cajun Holy Trinity for example. This crucial element to Cajun cooking is a play on the French mirepoix. 

In Cajun cuisine, a lot of the food we cook can be on the rich and heavier side. Think stews, rice, fried foods, heavy spice, and butter.

Adding persillade, a fresh parsley and scallion sauce, to a rich dish is a great way to balance it out by adding some brightness and acidity.

I’ve only occasionally seen persillade used with Cajun dishes, but I think we are missing a great opportunity to use it! Serve some persillade sauce with your next fried chicken dinner, spicy blackened fish, or buttery charbroiled oysters and see what I mean!

What is Persillade?

Persillade is a simple french sauce made with fresh parsley and garlic. It comes from the French word for parsley, persil

This condiment can be used as a garnish or added in during the cooking process. Some versions have additional ingredients added like vinegar, olive oil, shallots or onions, capers, or additional herbs. 

Think of persillade like the French version of the Argentinian chimichurri or the Italian gremolata.

Ingredients & Substitutions

Ingredients needed for persillade sauce.

See the recipe card below for the complete list of ingredients and measurements.

  • Fresh parsley – One bunch of parsley should be enough. Do not substitute for dried herbs in this recipe. 
  • Green onions – This is my Louisiana twist on this french sauce. Green onions are used heavily in Cajun and south Louisiana cooking, and they make a great addition to this sauce. You can substitute for chives if needed. 
  • Fresh garlic – Garlic gives this sauce a pungent and bold flavor. Don’t substitute for pre-minced garlic, it never tastes as good as freshly minced garlic. 
  • Extra virgin olive oil – Olive oil is the medium for this sauce. Use high quality olive oil since this sauce is not cooked and the flavor of the olive oil will be tasted. 
  • Lemon – You will need lemon zest and lemon juice for this recipe. 
  • Red wine vinegar – Adds another layer of flavor to this sauce. You can substitute for white wine vinegar or white balsamic vinegar.

Expert Tips

  • Zest first. If you’re making a recipe that requires both the juice of a lemon and the zest, always zest it first. It is much easier to zest a citrus before you cut it open!
  • Let it sit. This sauce is better after sitting for about 30 minutes before serving. This gives it time for the flavors to meld together. 
  • Serve it at room temperature. While you should store this sauce in the refrigerator, it is better to serve at room temperature. Remove it from the refrigerator about 30 minutes before serving. The olive oil will have time to melt back into a liquid. 

Storage & make ahead

How to store leftovers: Store leftover parsley sauce in an airtight container in the refrigerator for 3-4 days. Allow to come to room temperature before serving.

How to freeze: Do not freeze this recipe.
