Ingredients
  

  • Chicken: 4 boneless, skinless chicken thighs (or 2 large breasts, halved lengthwise)
  • Mushrooms: 12 oz (340 g) cremini or baby bella, sliced
  • Onion: 1 small yellow onion, finely chopped
  • Garlic: 3 cloves, minced
  • Butter: 2 tablespoons
  • Olive oil: 1 tablespoon
  • Heavy cream: 1 cup (240 ml)
  • Chicken broth: 1/2 cup (120 ml), preferably low-sodium
  • Cream cheese: 3 oz (85 g), softened
  • Parmesan: 1/3 cup, finely grated
  • Mozzarella: 1 cup, shredded
  • Fresh herbs: 1 tablespoon chopped thyme or parsley (plus more for garnish)
  • Spices: 1 teaspoon onion powder, 1/2 teaspoon paprika
  • Salt and pepper: To taste
  • Optional add-ins: 1/4 teaspoon red pepper flakes, splash of dry white wine, or a squeeze of lemon

Method
 

  1. Preheat the oven: Set to 375°F (190°C). Lightly grease a medium baking dish, or use an oven-safe skillet to keep it all in one pan.
  2. Season the chicken: Pat dry and season both sides with salt, pepper, onion powder, and paprika.
  3. Sear the chicken: Heat olive oil in a large skillet over medium-high. Sear chicken 3–4 minutes per side until golden. It won’t be fully cooked yet. Transfer to a plate.
  4. Sauté the mushrooms and onions: Reduce heat to medium. Add butter. Sauté mushrooms and onion with a pinch of salt for 6–8 minutes, stirring occasionally, until browned and most liquid evaporates.
  5. Add garlic and herbs: Stir in garlic, thyme, and red pepper flakes if using. Cook 30–60 seconds until fragrant.
  6. Build the sauce: Pour in chicken broth (and a splash of wine if using). Simmer 2 minutes, scraping browned bits. Stir in cream and cream cheese until smooth. Simmer gently 2–3 minutes to thicken slightly. Taste and season with salt and pepper.
  7. Combine and top: Nestle chicken into the sauce. Sprinkle Parmesan and then mozzarella evenly over the top.
  8. Bake: Transfer to the oven and bake 15–20 minutes, or until the chicken reaches an internal temperature of 165°F (74°C) and the cheese is melted and bubbly.
  9. Optional broil: For a golden top, broil 1–2 minutes. Watch closely to prevent burning.
  10. Rest and serve: Let stand 5 minutes. Garnish with fresh parsley or thyme. Serve with a simple side like roasted broccoli, sautéed spinach, or cauliflower rice.
