Preheat the oven to 350°F. Season the chicken thighs with salt and pepper.
Heat the oil in an ovenproof skillet set over high heat. Add the chicken skin-side down and sear to a golden brown on each side. Transfer the chicken to a plate and reserve. Pour off the excess oil in the skillet.
Reduce the heat to medium-high and melt the butter in the skillet and add the mushrooms and sprinkle with salt and pepper. Cook for 4-5 minutes, stirring occasionally until the mushrooms become light brown.
Add the chopped shallot and cook until the shallot is translucent, about 1 minute. Stir in the garlic and cook until the garlic is soft and fragrant.
Add the wine and simmer for 2-3 minutes to burn off the alcohol, scraping up the bits from the bottom. Stir in the chicken broth and thyme leaves.
Place the reserved chicken thighs back into the skillet, cover with a lid and transfer to the oven. Bake for 45 minutes.
Transfer the skillet from the oven, push the chicken to the side and stir the cream into the sauce. Serve with mashed potatoes or rice.
Notes
Chicken cut: This recipe uses bone-in, skin-on thighs. You can swap boneless thighs, but reduce the bake time to avoid overcooking.Check doneness: Chicken thighs are best cooked to 175°F. The extra heat breaks down connective tissue, leaving the meat juicy, tender, and easy to pull from the bone.Skillet choice: Use an oven-safe pan like cast iron or stainless steel so you can sear and bake in the same dish.Serving suggestion: Pasta, rice, or bread are ideal for soaking up the sauce.Storage: Leftovers keep in the fridge for 3–4 days. Reheat gently on the stove so the cream doesn’t separate.
