This post describes how to confit duck, for both preservation and gastronomic delight. If you already have legs of duck confit, whether store bought or prepared at home, see my crispy duck confit recipe.
Confit, French for "preserved," is a centuries-old method of preparation that involves salt curing a cut of meat, slowly poaching the meat in its own fat, and then storing the meat encased in that fat. Traditionally a preservation method before the advent of refrigeration, the meat would last for months, with the fat providing protection from both oxygen and light. Today, the preservation aspect is not a necessity, but we still make confit for its deliciously-intense flavor and decadent texture. The fat, dense and flavorful, is the perfect cooking medium, allowing the meat to remain succulent and moist.

Duck Confit (Confit de Canard)Preparing confit is a multi-day project, although most of that time is unattended. On day one, you salt cure the meat with spices and garlic. A day or two later, you remove the meat, wipe it clean, and then slow poach it in the oven submerged in its own fat. About three hours later, you remove the legs and strain the fat. The legs, again submerged in fat, are stored in an airtight and opaque container, traditionally glazed earthenware, in the refrigerator. You'll want to let the confit rest, or "ripen," for at least two days after that. Its worth preparing a big batch so as to always have duck legs in the refrigerator, ready to reheat on a moment's notice.
Many types of meats may be prepared confit. The most popular is duck or goose. This guide walks you through preparing a confit of duck legs.
Makes four legs of duck confit.
Ingredients:
4 Moulard duck legs (about 3 pounds in total), excess flaps of fat trimmed
8 cloves garlic, smashed
4 sprigs thyme, each snapped in half
2 sprigs rosemary, each snapped in half
2 bay leaves, each cut in half
1/2 teaspoon cinnamon
1 tablespoon freshly-ground black pepper
4 tablespoons kosher salt
2-3 pounds rendered duck fat
In a large mixing bowl, combine the duck legs, garlic, thyme, rosemary, bay leaves, cinnamon, black pepper and kosher salt. Mix together very well, ensuring that each duck leg is coated with the salt. Transfer all of the ingredients to a large, heavy-duty zip-lock bag. Press as much as the air out of the bag as possible and seal. Alternatively and preferably, vacuum pack the ingredients on low. Store in the refrigerator for 36 hours.
Preheat the oven to 200°F.
Remove the duck legs from the refrigerator. Thoroughly brush off all of the salt, spices, and garlic from the duck legs. Gently rinse with cold water. Pat completely dry with paper towels.
In a large dutch oven over low heat, slowly melt the rendered duck fat. Once melted, add the duck legs. They should be fully submerged in the fat. Raise the heat to medium. Bring the fat to a low simmer. Once simmering, cover and transfer to the oven. Cook until the duck is fork tender, the fat is fully rendered, and any juices have evaporated, about 3 hours.
Remove from oven. Let cool for 30 minutes. Using a slotted spoon, remove the duck legs and reserve. Strain the rendered fat through a mesh strainer.
Place the duck legs in your storage container, which is traditionally glazed earthenware, although a Pyrex casserole with a tight lid is perfect. Ideally, divide the confit up into multiple containers each with only one or two legs, to better utilize space and match your serving size. Cover the legs in the strained fat, which should be clear and free of meaty bits and non-fat juices. The legs should be fully covered. Knock against the counter to dislodge any air bubbles. Transfer to the refrigerator and cool until the fat hardens.

Confit of duck legs stored in a vacuum packRemove from the refrigerator and check that the legs are fully submerged in fat, with at least a half inch of fat above the legs. Add more duck fat as needed. Alternatively, vacuum pack on medium the duck legs encased in the solidified fat. Return to the refrigerator.
Let meld and intensify in the refrigerator for at least 48 hours before eating. Will keep several months.
