Add the garlic to the pan and cook until lightly browned and fragrant, 3 to 5 minutes. Add the bacon, fennel, apples and salt and give everything a good stir. Continue cooking on high heat for 5 minutes more, until the fennel is looking translucent and is soft to the touch, and the apples start to caramelize. Add the cider, scrape the bottom of the pan to deglaze, bring the mixture to a boil, turn off the heat and transfer the pan to the oven, uncovered.
Cook the chicken and vegetables for 50 to 60 minutes, or until the top of the chicken looks dark and the liquid has reduced by half. Really, you could pull it out after 30 minutes (or as soon as an instant-read thermometer shows an internal chicken temperature of 165 degrees), but use the longer time if you want the meat falling apart. Serve with roasted potatoes alongside.
