Preheat oven to 375°F.
Season the chicken: Pat chicken dry and season both sides with salt, pepper, garlic powder, onion powder, paprika, and thyme.
Sear the chicken (optional but recommended): Heat olive oil in a large skillet over medium-high heat. Sear chicken for 2-3 minutes per side until golden. Transfer to a 9x13-inch baking dish.
Prepare the sauce: In a bowl, mix cream of mushroom soup with chicken broth and Worcestershire sauce (if using). If using fresh mushrooms, sauté them in butter first, then add to sauce.
Bake: Pour sauce over chicken. Cover with foil and bake for 25 minutes. Remove foil and bake an additional 10-15 minutes until chicken reaches 165°F internal temperature and sauce is bubbly.
Serve: Let rest 5 minutes. Garnish with fresh parsley and serve over rice, mashed potatoes, or egg noodles.
