Heat oven to 375°F with a rack in the center.
Warm 1 tablespoon oil in a large Dutch oven over medium heat.
Cook bacon until crisp, 6–8 minutes. Scoop out and set aside.
Brown sausage slices in the bacon fat, 3–4 minutes per side. Remove and reserve.
Season chicken with some salt and pepper. Sear until golden, then transfer to a plate.
Add onion, carrot, and celery. Soften until glossy, about 5 minutes.
Stir in garlic and tomato paste. Cook until the paste darkens slightly, about 1 minute.
Pour in wine and scrape up browned bits. Reduce by half, 2–3 minutes.
Add broth, beans, thyme, smoked paprika, bacon, sausage, and chicken. Bring to a gentle simmer.
Combine panko, parsley, melted butter, and remaining 1 tablespoon oil. Sprinkle evenly over the pot.
Bake uncovered until bubbling and the top is golden, 25–30 minutes. Broil 1–2 minutes if darker is desired.
Rest 10 minutes, taste, and adjust salt and pepper before serving.
