Persillade

Also known as parsley and garlic, persillade mixture

Fresh herb mixture

Quick answer

Flat-leaf parsley and garlic chopped together, the French finishing seasoning thrown over sautéed potatoes, mushrooms, snails, frogs’ legs and grilled meat in the last seconds of cooking. It is two ingredients and a timing, and the timing is most of it.

In essentially every version: Fresh flat-leaf parsley, Garlic.

2 distinct versions are set out below. None of them is presented as the correct one, because there isn’t one.

What goes in it

The defining core first, then the versions, with what each ingredient is there to do.

Ingredients common across versions
IngredientRoleHow essential
Parsley (fresh)basedefining
Garlic (fresh)savoury depthdefining
Why versions differ:

Low. Parsley and garlic, finely chopped together, define it; the ratio varies with taste and region, the south using more garlic. Adding breadcrumbs, olive oil or butter makes the crumb persillade used for gratins and roasts. Shallot sometimes replaces some of the garlic.

Garlic133%

Worked into three to four times its volume of fresh breadcrumbs. The crumbs are a carrier rather than a seasoning and are not listed as an ingredient — but they bring gluten, which the herb mixture alone does not.

Using it

Added at the very end, into hot fat, and tossed for no more than a few seconds before serving. Added earlier, the garlic scorches and turns bitter and the parsley loses its colour.

Traditional practiceStandard French practice; follows from how quickly finely chopped garlic burns.
Flavour:

Green, fresh and sharply garlicky. Thrown into a hot pan it softens in seconds: the raw garlic bite rounds off and the parsley releases its aroma without cooking to khaki.

Traditional practiceFollows from the ingredients and the timing.
Heat:

None; raw garlic has pungency but no heat.

Culinary conventionGarlic pungency is not chilli heat.
Suits:
  • Sautéed potatoes (pommes de terre sautées)
  • Mushrooms and ceps
  • Snails and frogs’ legs
  • Grilled steak and lamb
  • Tomatoes provençale
Traditional practiceThe uses described in French cooking.

Scaling: Scale by the parsley and add garlic to taste. Chop it just before use: chopped garlic and parsley both deteriorate within the hour.

What to use it on

Mushrooms

Classic

Cèpes and other mushrooms sautéed and finished with persillade are a classic of the French south-west; parsley and garlic are the seasoning mushrooms are most often given in France.

How: Cèpes à la bordelaise; Sautéed mushrooms

Documented in cuisineFrenchSources: Established culinary practice

Potato

Classic

Pommes de terre sautées finished with persillade in the last seconds of cooking are a French standard; the hot fat softens the raw garlic just enough.

How: Pommes de terre sautées; Pommes sarladaises

  • Added any earlier the garlic scorches and the parsley turns khaki.

If you have none

Gremolata

Situational

Gremolata is persillade with lemon zest. As a raw finish over grilled meat or fish it works well; tossed into hot fat as persillade is, the zest turns bitter and its oil burns off.

Storage

Conditions:

Made at the moment of use.

Culinary conventionChopped parsley and garlic deteriorate quickly.

Loss of freshness is a quality matter. Chopped garlic is best used the day it is chopped and not kept at room temperature in oil.

Allergens and safety

Allergens:
    Strong evidenceSources: Regulation (EU) No 1169/2011 on the provisi…; Major food allergens under FALCPA and the F…

    Not among the substances that must be declared as allergens under EU Regulation 1169/2011 Annex II or under the United States major food allergen rules. That is a statement about labelling law and not about whether allergy occurs: allergic reactions to spices are documented in the clinical literature and are simply not a labelling category. Where a ground spice presents an allergen risk it is usually through adulteration or shared processing equipment rather than through the plant itself.

    Culture and origin

    Origin:

    France, where persillade is a basic preparation of home and restaurant cooking across the country and particularly in the south-west and Provence. With breadcrumbs added it becomes the crust for a gratin or a rack of lamb.

    Reasonable evidenceSources: The Oxford Companion to Food

    France

    One of the handful of basic preparations a French cook learns early, and the flavour of a great deal of bistro food. In the south-west it goes onto potatoes fried in duck fat; in Provence onto tomatoes.
