Ingredients :

• Chicken with bone and skin — Thighs, drumsticks, or both — they are ideal here. The bone keeps the meat juicy during the long cook, and the skin crisps up on top. Skinless chicken breasts cook too fast and dry out. You really want the chicken with everything it’s got.
• Green beans — Fresh, thawed frozen, or drained canned — all three options work. Fresh ones have more bite, frozen ones are perfectly fine. Canned beans will be softer, but still delicious. No need to pre-cook them; they cook right in the dish.
• Condensed cream of mushroom soup — Use it as is, without diluting it. It will thin out with the cooking juices and create that sauce that gives the dish its character. Any brand of condensed cream of mushroom works — no need for a premium version.
• Butter — Cut into small cubes and scattered on top before baking. It melts, incorporates into the cream, and provides that richness you feel from the very first bite. Unsalted or salted — if using salted, go easy on any extra salt.
