En Papillote
Also: al cartoccio, in parchment, parchment-baked, packet cooking
A technique in which food and aromatics are sealed inside a folded parchment or foil packet and baked, creating a self-contained steam environment that preserves moisture and concentrates flavor.
/ahn pa-pee-YOT/French, from 'papillote' (a curl of paper, originally used to decorate the end of a cutlet bone — the same root as English 'papillote' candy wrapper). The culinary technique gained prominence in classical French cuisine of the 19th century, codified in Escoffier's 'Le Guide Culinaire'.
Definition
En papillote (French for 'in parchment') is a cooking method in which a portion of food — most often a delicate protein such as fish, chicken breast, or shellfish, along with aromatics, vegetables, and a small amount of liquid or fat — is enclosed in a tightly sealed packet of baking parchment (or aluminum foil) and cooked in a hot oven, typically at 200–220 °C (400–425 °F). As the packet heats, any moisture present (from the food itself, added wine, citrus juice, or butter) vaporizes but cannot escape the sealed environment; the result is a pressurized steam pouch that cooks the food quickly, evenly, and without drying. The packet puffs dramatically in the oven as steam inflates it. The food is cooked simultaneously by the surrounding steam and by the radiant heat of the oven transferred through the packet wall. Opening the puffed packet tableside releases an aromatic cloud of steam — a classic French bistro presentation. The technique is almost uniquely suited to delicate proteins: collagenous cuts, which require long moist cooking to become tender, fare poorly, as do large whole items that require more time than the packet can contain steam. However, for a single-portion fish fillet, scallops, thin chicken breast, or vegetables cut to even thickness, en papillote produces exceptionally moist, aromatic results with minimal fat and no loss of juices to the surrounding cooking environment. The Italian equivalent, al cartoccio, follows the same logic and is common in Ligurian and Campanian fish cookery.
In use
“A fillet of sole is layered over julienned fennel and lemon slices on a half-sheet of parchment, dotted with butter and splashed with white wine; the parchment is folded and crimped into a sealed half-moon, baked at 210 °C for twelve minutes, and brought to the table puffed and fragrant.”

Notes
Parchment vs. foil
Parchment paper is the traditional material, favored for table presentation (the visual puff and aromatic reveal) and for its slightly permeable nature at the seal, which allows a modest amount of vapor to escape and prevents over-pressurization. Aluminum foil is used when a completely impermeable, tight seal is required — common for campfire cooking (the 'hobo packet') and for items that benefit from absolute moisture retention. Foil reflects more infrared radiation than parchment, subtly changing heat distribution. Neither should be used at very high temperatures with acidic ingredients for extended periods: acid attacks both.
The crimping seal
The seal is functional, not decorative. A properly crimped parchment packet — the edge folded in small, overlapping pleats — holds the steam pressure generated during cooking without blowing open. The packet must also be sized generously so there is headroom above the food; if the parchment rests directly on the surface, steam has nowhere to accumulate and the top surface essentially steams against paper rather than air-circulating steam, which can produce an uneven texture.
Aromatics strategy
The sealed environment means every aromatic compound released during cooking is reabsorbed by or deposited on the food — there is no evaporation to a room or reduction into a sauce. This concentrating effect makes en papillote particularly unforgiving of heavy-handed seasoning or overpowering aromatics (raw garlic, very strong herbs). Delicate aromatics — fresh tarragon, thin lemon slices, a few drops of good olive oil, dry vermouth — shine in the format, while robust ones can overwhelm.
