Cassoulet casserole is a simplified take on the classic French slow-cooked bean and meat dish from the Languedoc region. It layers creamy white beans, tender chicken, sausage, and pork under a golden breadcrumb crust, delivering all the deep, comforting flavor of a traditional cassoulet in a fraction of the time. This version uses everyday ingredients and one baking dish, making it a practical weeknight dinner that still feels special.
Ingredients
- 4 slices bacon, chopped
- 4 bone-in, skin-on chicken thighs (about 1.5 lb / 680 g)
- 1 lb (450 g) pork sausage links (or kielbasa), sliced into 1/2-inch rounds
- 1 large onion, chopped
- 3 cloves garlic, minced
- 2 carrots, peeled and diced
- 2 celery stalks, diced
- 2 tablespoons tomato paste
- 1 can (14.5 oz / 411 g) diced tomatoes, undrained
- 2 cans (15 oz / 425 g each) cannellini beans, drained and rinsed
- 1 cup (240 ml) chicken broth
- 1 teaspoon dried thyme
- 1 bay leaf
- Salt and freshly ground black pepper, to taste
- 1 cup (90 g) fresh breadcrumbs
- 2 tablespoons unsalted butter, melted
- 2 tablespoons chopped fresh parsley (optional, for garnish)
Instructions
- Preheat your oven to 375°F (190°C).
- In a large Dutch oven or oven-safe skillet over medium heat, cook the bacon until crisp, about 5 minutes. Remove with a slotted spoon and set aside, leaving the drippings in the pan.
- Season the chicken thighs with salt and pepper. In the same pan, sear the chicken skin-side down until golden brown, about 4-5 minutes per side. Remove and set aside.
- Add the sausage slices to the pan and cook until browned on both sides, about 3 minutes per side. Remove and set aside.
- Add the onion, carrots, and celery to the pan. Cook, stirring occasionally, until softened, about 5 minutes. Add the garlic and tomato paste, and cook for 1 minute more.
- Stir in the diced tomatoes, beans, chicken broth, thyme, bay leaf, and the reserved bacon. Bring to a simmer.
- Nestle the chicken thighs and sausage into the bean mixture. The liquid should mostly cover the beans, but the chicken skin should remain exposed.
- In a small bowl, mix the breadcrumbs with the melted butter. Sprinkle evenly over the top of the casserole.
- Transfer the pot to the oven (or cover a separate baking dish with foil if not oven-safe). Bake uncovered for 45 minutes, until the casserole is bubbling and the crust is golden brown.
- Remove from the oven and let rest for 10 minutes. Discard the bay leaf. Garnish with parsley, if using, and serve.
Tips
- Use already-cooked beans: Canned beans are essential for keeping this recipe quick. If you prefer dried beans, soak and cook them first—this will add about 2 hours to the total time.
- Don’t skip the sear: Browning the chicken and sausage builds deep flavor and helps render fat, which enriches the sauce. It also ensures the chicken stays moist during baking.
- Make ahead: Assemble the casserole (without the breadcrumb topping) up to 2 days ahead. Cover and refrigerate. When ready to bake, add the crumbs and increase baking time by 10-15 minutes.
- Common mistake: Overcrowding the pan when searing can steam the meat instead of browning it. Work in batches if needed.
Serving Suggestions
Serve this cassoulet casserole with a simple green salad dressed with vinaigrette and a crusty baguette to soak up the rich sauce. It also pairs well with steamed green beans or a side of roasted root vegetables.
Variations
- Duck confit: For a more traditional cassoulet, replace the chicken thighs with 2 duck confit legs (shredded or whole). Reduce the chicken broth to 1/2 cup (120 ml) as duck is richer.
- Vegetarian: Omit the bacon, chicken, and sausage. Add 2 cups (300 g) of diced butternut squash and 1 cup (150 g) of mushrooms. Use vegetable broth and add 1 tablespoon of smoked paprika for depth.
- Spicy: Use hot Italian sausage and add 1/2 teaspoon of red pepper flakes with the garlic.
Storage and Reheating
Refrigerate leftovers in an airtight container for up to 4 days. To reheat, place a portion in a saucepan with a splash of broth or water, cover, and warm over medium-low heat until heated through, about 10 minutes. Alternatively, reheat in the oven at 350°F (175°C) for 20 minutes. The breadcrumb crust will soften upon storage; for a crisp topping, reheat under the broiler for 2-3 minutes.
Frequently Asked Questions
Can I use boneless, skinless chicken thighs? Yes, but reduce the searing time to 2-3 minutes per side, and add the chicken to the pot with the beans rather than nesting on top, as it will cook faster and dry out if left exposed.
What can I substitute for cannellini beans? Great northern beans, navy beans, or even chickpeas work well. The texture will vary slightly, but all hold up to long cooking.
Can I freeze this casserole? Yes, freeze before adding the breadcrumb topping for up to 3 months. Thaw overnight in the refrigerator, then add crumbs and bake as directed. If freezing after baking, cool completely, wrap tightly, and freeze for up to 2 months.
Why is my casserole dry? This can happen if the liquid reduces too much. Ensure the beans are mostly submerged before baking, and check at the 30-minute mark—if it looks dry, add 1/4 cup (60 ml) of broth.
Is this the same as a traditional cassoulet? No, a traditional cassoulet is a slow-cooked dish that can take days, with layers of meat and beans cooked slowly. This casserole is a weeknight-friendly adaptation that captures the essence in about 1.5 hours.
How do I know the chicken is fully cooked? The chicken is safe to eat when it reaches an internal temperature of 165°F (74°C) as measured with a food thermometer. Insert the thermometer into the thickest part of the thigh, avoiding the bone.
