Persillade

Persillade (French pronunciation: [pɛʁsijad]) is a sauce or seasoning mixture of parsley (French: persil) chopped together with seasonings including garlic, herbs, oil, and vinegar.

In its simplest form, just parsley and garlic, it is a common ingredient in many dishes, part of a sauté cook's mise en place. If added early in cooking, it becomes mellow, but when it is added at the end of cooking or as a garnish, it provides a garlicky jolt. It is extensively used in French and French-influenced cuisines, as well as in Cajun, Louisiana Creole, and Québécois cuisines.

A classic French and Quebec bistro dish is pommes persillade, cubed potatoes fried in a small amount of oil, with persillade added at the end of the cooking, and can sometimes be combined with Quebec poutine to produce a hybrid dish called poutine persillade. Persillade is also popular in Louisiana; New Orleans chef Austin Leslie's signature dish was fried chicken with persillade.
