En papillote is a French cooking technique where food is enclosed in parchment paper or aluminum foil and baked. The parcel seals in the flavors and aromas of the ingredients, keeping them moist and tender while cooking. The dish is typically opened at the table, releasing the fragrant steam and creating a visually impressive presentation. En papillote dishes can be served in the parchment paper or foil packet itself or transferred to a plate. The technique is commonly used for fish, chicken, and vegetables, often seasoned with herbs and citrus fruits.
