In a large skillet over medium heat, cook the bacon for 3 to 4 minutes, stirring frequently, until it renders much of its fat but is not yet crisp. Transfer the bacon to a large plate.

Pat the chicken dry with a paper towel and season both sides with salt and black pepper. Prick each sausage with the tip of a paring knife in a couple of places. This will prevent them from bursting as they cook.

In the same skillet used to cook the bacon, add 1 tablespoon olive oil and heat it over medium-high heat. No need to drain out the bacon grease. Add the chicken, skin side-down, and the sausages. You may need to do this in batches if the skillet is not large enough. Cook the meat until golden brown on both sides, 8 to 10 minutes. Transfer them to the plate with the bacon one by one as they look ready.

Pour off and discard all but a thin layer of fat from the skillet. Return the skillet to the stove over medium heat. Add the onions and garlic and cook for 3 to 4 minutes, until the onions soften.

Transfer the cooked onions and garlic into a large (at least 4-quart) Dutch oven. Stir in the tomatoes, beans with their liquid, and thyme sprigs. Nestle in the bacon, chicken thighs, and sausages. Bring the cassoulet to a simmer over medium heat. Adjust the heat to a steady simmer and cook, uncovered, for 15 minutes, until the chicken and sausages are cooked through. The chicken should measure 165ºF when an instant read thermometer is inserted into the thickest part of the meat.

Set a rack about 8 inches from the broiler element and turn on the broiler.

In a small bowl, toss the breadcrumbs with the remaining 1 tablespoon olive oil and parsley.

Remove and discard the thyme sprigs from the cassoulet. Evenly sprinkle in the breadcrumbs and place the Dutch oven into the oven to broil for 1 to 2 minutes, until the top browns. Watch it carefully—this only takes a minute or two. Remove the cassoulet from the oven and sprinkle in more parsley, if you’d like.

Ladle some beans into 4 shallow bowls. Top each bowl with a sausage and a chicken thigh. Serve with a baguette on the side and a large spoon to scoop up all the delicious juices.
