01 - Preheat oven to 400°F. Lightly grease a 9x13-inch baking dish with olive oil or nonstick spray.
02 - Season both sides of the chicken breasts with salt, black pepper, paprika, and thyme.
03 - In a large skillet over medium heat, melt the butter with olive oil. Add sliced mushrooms and sauté for 4–5 minutes until they soften. Stir in minced garlic and cook an additional minute.
04 - Remove mushrooms from heat. Arrange the seasoned chicken breasts in the prepared baking dish. Distribute the sautéed mushrooms and garlic evenly over the chicken. Pour chicken broth around the chicken, avoiding direct contact with the toppings.
05 - Evenly sprinkle mozzarella and Parmesan cheese over the surface.
06 - Bake uncovered for 25–30 minutes until chicken reaches an internal temperature of 165°F and cheese is melted, bubbling, and golden-brown.
07 - Allow to rest for 5 minutes before serving. Garnish with fresh herbs as desired.
