Step 1

Soak the beans. Place 1 pound dried great northern beans in a large bowl. Add enough cold water to cover the beans by 2 to 3 inches. Soak at room temperature for at least 8 hours or preferably overnight.

Step 2

Boil the beans for 5 minutes. Drain the beans. Place the beans in a large pot and add enough cold water to cover them by 2 inches. Bring to a rapid boil over medium-high heat and boil for 5 minutes. Drain again.

Step 3

Cook the beans. Bring 2 1/2 quarts unsalted chicken stock or broth to a boil over medium-high heat in the same pot. Add the beans, bring back to a boil, and skim off any scum. Reduce the heat to maintain a simmer and cook uncovered until the beans are just tender but still whole and unbroken, 45 minutes to 1 hour. Meanwhile, prepare the meats.

Step 4

Cut the meats. Dice 3 ounces salt pork. Halve 2 duck confit legs between the joint so that you have 2 drumsticks and 2 thighs. Cut 8 ounces garlic sausage into 2-inch pieces. Cut 4 ounces boneless pork shoulder or belly into 2-inch chunks. Cut 4 ounces fresh pork skin into 2-inch squares if using.

Step 5

Make a salt pork and garlic paste. Place the salt pork and 3 garlic cloves in a food processor fitted with the blade attachment. Process into a sticky paste, about 15 seconds. (Alternatively, chop by hand into a paste.) Refrigerate until ready to use.

Step 6

Sear the duck and pork. Place the duck skin-side down in a large frying pan over medium-low heat and cook until golden-brown, 5 to 10 minutes per side. Transfer to a plate. Add the sausage to the pan and cook into browned, about 4 minutes per side. Transfer to the plate. Add the pork belly or shoulder and cook until browned on a few sides, about 3 minutes per side. Transfer to the plate. Refrigerate the meats until ready to use.

Step 7

Cool the beans. When the beans are ready, remove from the heat and let cool until warm to the touch, about 1 hour.

Step 8

Season the beans. Add the garlic-pork paste, 1 teaspoon ground nutmeg, and 1/4 teaspoon kosher salt to the beans and stir gently to combine, breaking up the paste so that is it evenly distributed.

Step 9

Drain the beans. Pour the bean mixture through a strainer fitted over a large bowl.

Step 10

Line the cooking vessel. Use a cassole if you have one. Otherwise you can use a 3 1/2-quart Dutch oven or other heavy-bottomed, oven safe pot. Line the bottom of the vessel with the cut pork skin if using.

Step 11

Assemble the cassoulet. Layer half of the beans on top of the pork skin. Place the duck confit and pork shoulder or belly on the beans. Layer the remaining beans over the duck and pork. Top with the sausages, nestling them into the beans until just their tops are visible.

Step 12

Top with cooking liquid. Pour enough of the bean cooking liquid into the cassoulet to barely cover the beans. Sprinkle a dusting of freshly ground black pepper across the surface. You can immediately move on to the next step and bake it for 3 hours, or the cassoulet can be covered and refrigerated overnight. Refrigerate the remaining bean cooking liquid.

Step 13

Bake the cassoulet for 3 hours. Arrange a rack in the middle of the oven and heat the oven to 325ºF. Bake the cassoulet uncovered for 3 hours. While it is cooking, it will develop a brown crust on top. Pierce the crust and moisten the surface by spooning some of the cooking liquid over it, taking care not to disturb the layers below. Allow the crust to re-form 2 or 3 times. If the beans start to look dry, moisten them with several spoonfuls of extra bean-cooking liquid or chicken broth. Let the cassoulet cool to room temperature, then cover and refrigerate overnight.

Step 14

Bake the cassoulet for 1 1/2 hours. Arrange a rack in the middle of the oven and heat the oven to 325ºF. Uncover the cassoulet and bake for 1 1/2 hours, breaking the crust with a spoon and moistening the surface at least twice. If the beans look dry, add spoonfuls of extra bean-cooking liquid or chicken broth. You can serve the cassoulet now, or let it cool to room temperature and cover and refrigerate overnight.

Step 15

Heat the cassoulet for 1 1/2 hours. Arrange a rack in the middle of the oven and heat the oven to 325ºF. Heat the cassoulet for 1 1/2 hours, moistening with extra bean-cooking liquid or chicken broth as necessary. Serve immediately in its vessel, gently simmering and unstirred.
