Start by preheating your oven to 375°F (190°C).
Pat the chicken thighs dry with paper towels, then season generously on both sides with salt and pepper.
In a large cast iron or oven-safe skillet, heat the oil over medium-high heat. Place the chicken thighs skin-side down in the skillet and sear for 5-6 minutes, until the skin is golden and crispy. Flip the thighs and sear the other side for an additional 2 minutes.
Add the shallots, garlic, and apple slices to the skillet, allowing them to soften for 1 -2 minutes. Then, pour in the apple cider and chicken stock and finally the fresh herbs.
Transfer the skillet to the preheated oven and bake uncovered for 25-30 minutes, or until the chicken reaches an internal temperature of 165°F (75°C).
(optional): After removing from the oven, you can stir in a tablespoon of butter to enrich the sauce. Taste and adjust seasoning with salt and pepper if needed.
Serve: Plate the chicken with the apples, shallots, and garlic. Spoon some of the flavorful braising liquid over the top.
