Cassoulet de Castelnaudary — white beans, duck confit & Saucisse de Toulouse

Soak the beans — time as an ingredient (day 1)

Soak the white beans in plenty of cold water (three times their volume) in a large bowl for at least 12, better 24 hours. Change the water once. Tarbais beans are the original — their thin skin stays intact through long cooking, without turning mealy. Lingots du Lauragais are the more affordable variant from the same region and work just as well. Large white beans or supermarket cannellini go mushy — do not substitute.

Pre-cook the beans with the rind and aromatics (day 2)

Tie the pork rinds loosely with kitchen string into one or two rolls (so they can be lifted out easily later). Drain the beans, place them in a large pot, add the rind rolls, crushed garlic, half an onion studded with the cloves, the bouquet garni and the peppercorns. Cover with cold water and bring to a bare simmer (do not salt!), then cook for 1 hour at the gentlest simmer until the beans are tender but still have bite. Season with salt only after 45 minutes (salting too early hardens the bean skins).

Build the braising vegetables

While the beans cook, heat 2 tbsp duck fat in a heavy pan. Sweat the diced onion, carrots and chopped garlic over medium heat for 8–10 minutes, until they are soft and lightly golden. Add the tomatoes (or tomato paste) and let them roast along for 5 minutes. Deglaze with the white wine (optional), reduce for a few minutes. Set aside.

Brown the sausage and meat

Cut the Saucisse de Toulouse into 4 cm pieces. Season the pork shoulder with salt and pepper. In a pan, heat 1 tbsp duck fat and brown the sausage pieces and shoulder cubes all over to golden (about 8 minutes). Do not cook through — just colour. Remove and set aside.

Prepare the duck confit

Lift the confit legs from the fat at room temperature, scrape off the excess fat. In a dry pan, skin-side down, crisp for 5 minutes over medium heat — the skin will have to carry the crust later. Split each leg into thigh and drumstick, set aside.

Layer everything in the cassole

Preheat the oven to 150 °C conventional. Grease a terracotta cassole (traditionally: wide and deep, 5–6 litres, flared outwards — that is what gives Castelnaudary its name!) or a cast-iron braiser with duck fat on the inside. Layer from the bottom up: 1. Half of the beans (lifted from the pot with a little stock), the rind pieces (untied and laid flat), the pork shoulder and sausage, the braising vegetables, the duck confit skin-side up, then the rest of the beans. The duck confit skin must always stay visible on top — it will carry the crust later.

Top up with bean stock and roast slowly in the oven

Top up with hot bean stock so that the beans are just covered — not the confit skin. If there is too little stock: pour in hot water. Drizzle 1 tbsp duck fat over the surface (gives the later roasted crust-notes). Place uncovered (no lid) in the oven and roast slowly for 2 hours at 150 °C — the surface forms a golden-brown crust, the beans draw the stock into themselves.

Press the crust in 7 times — „casser la croûte sept fois“

This is the actual technique of the Castelnaudary: every 15–20 minutes press the golden crust back into the beans with a flat wooden spoon (do not lift it — press it in), so that a new one can form. Seven times in total, spread across the roughly 2 hours of cooking. After each pause top up with fresh stock if the surface looks too dry. With every crust cycle the pot grows deeper, more aromatic, more complex.

Let the final crust form and serve

After the seventh crust-pause do not press down the final crust — it is allowed to stand. Leave it in the oven 15 minutes longer, until it is dark golden-brown. Take it out and let it rest for at least 20 minutes — a cassoulet is at its best at around 65 °C, never boiling hot. Carry the cassole straight to the table; the first portion breaks through the crust and reveals the creamy bean-and-meat layering beneath.
