01 - Preheat oven to 375°F.
02 - Pat chicken breasts dry and season both sides with salt, pepper, and smoked paprika.
03 - In a large ovenproof skillet, heat olive oil over medium-high heat. Sear chicken breasts for 3–4 minutes per side until golden. Remove to a plate.
04 - In the same skillet, add chopped bacon. Cook until crispy; remove and set aside, reserving about 1 tbsp bacon fat in the skillet.
05 - Add mushrooms to the skillet. Sauté 3–4 minutes until softened. Add garlic and cook 1 minute more.
06 - Pour in chicken broth, scraping up any browned bits. Stir in heavy cream and Worcestershire sauce. Simmer 2–3 minutes to thicken slightly.
07 - Return chicken to the skillet and spoon sauce over each piece. Top with cooked bacon, cheddar, and mozzarella cheese.
08 - Transfer skillet to the oven and bake uncovered for 15–18 minutes, until chicken is cooked through (internal temp 165°F) and cheese is melted and bubbling.
09 - Sprinkle with green onions and parsley before serving.
