Confit
Confit is a French cooking technique where food is slowly cooked submerged in fat at low temperatures (200-300°F), well below deep-frying temperatures, originally developed as a preservation method before refrigeration.
Confit is a French cooking technique where food is slowly cooked submerged in fat at low temperatures (200-300°F), well below deep-frying range. The word comes from the French verb “confire” meaning “to preserve,” and the method was originally developed in southwestern France’s Gascony region as a preservation technique before refrigeration existed.
Traditional meat confit involves salt-curing the protein first, then cooking it completely submerged in its own rendered fat. Duck and goose confit are the classic preparations—in French culinary tradition, only duck and goose cooked in their own rendered fat are considered “true confits.” Other meats cooked in duck or goose fat are called “en confit.”
How the Technique Works
Confit keeps meat exceptionally moist by cooking at temperatures that never exceed 185°F for traditional preparations. This low heat minimizes moisture loss from muscle fibers while the fat transfers heat evenly throughout the protein. A probe thermometer is essential for monitoring fat temperature during cooking to maintain the proper range.
After cooking, the meat is stored completely submerged in the cooking fat. This creates an anaerobic environment that prevents bacterial growth, allowing properly sealed confit to last several months to six months when refrigerated. The cooking fat can be strained and reused multiple times when properly filtered and stored in clean containers.
Confit vs. Deep Frying
The temperature difference is crucial. Deep frying operates at 325-450°F, creating crispy crusts through the Maillard reaction and rapid moisture evaporation. Confit’s lower 200-300°F range slowly tenderizes food without browning, producing rich, umami-forward results with completely different texture and flavor profiles.
Modern Applications in Professional Kitchens
Contemporary chefs have expanded confit beyond traditional duck and goose to include vegetables (garlic, onions, tomatoes, cauliflower), fish (cod, salmon, tuna), and even fruits. These preparations typically use olive oil rather than animal fats. Garlic confit is particularly popular, yielding both tender, spreadable cloves and flavored oil that can be used in other preparations.
Restaurant confit is often prepared during mise en place as a make-ahead component. For service, the meat is removed from fat, excess is wiped away, and the skin is crisped under a broiler or salamander for a few minutes until golden and crispy before plating.
Equipment and Modern Methods
Traditional confit requires a heavy pot or Dutch oven for even heat distribution, a thermometer to monitor oil temperature around 200°F, tongs for handling, and airtight storage containers. Modern kitchens can also use sous vide equipment with vacuum-sealed bags, requiring minimal fat while achieving similar tender results. This approach is similar to braising but uses fat instead of liquid as the cooking medium.
After cooking, confit must cool completely in the fat before storage or further preparation—this resting period allows the meat to reabsorb some fat and fully develop its tender texture.
Common Uses
In professional kitchens, confit is prepared during mise en place as a make-ahead component. Chefs most commonly confit duck legs, but the technique is also applied to garlic (for spreads and flavored oils), tomatoes (for pasta and garnishes), and proteins like pork belly or salmon. For service, confited meats are removed from fat, wiped clean, and crisped under a salamander to achieve golden, crackling skin before plating. The cooking fat is strained and reused for subsequent batches, making it an economical technique despite the initial fat investment.
