Ingredients
  

  • 1.5 lbs (680 g) boneless, skinless chicken thighs (or breasts, see notes below)
  • 10 oz (285 g) cremini or button mushrooms, sliced
  • 1 small yellow onion, thinly sliced
  • 3 cloves garlic, minced
  • 1 cup (240 ml) heavy cream
  • 1/2 cup (120 ml) chicken broth (low-sodium)
  • 4 oz (115 g) cream cheese, softened and cubed
  • 1 cup (100 g) shredded mozzarella
  • 1/2 cup (50 g) grated Parmesan
  • 2 tbsp olive oil or avocado oil
  • 2 tbsp butter
  • 1 tsp Dijon mustard (optional, for depth)
  • 1 tsp dried thyme (or 2 tsp fresh, chopped)
  • 1/2 tsp dried rosemary (or 1 tsp fresh, chopped)
  • 1/2 tsp smoked paprika
  • Salt and black pepper, to taste
  • Fresh parsley, chopped, for garnish

Method
 

  1. Prep the oven and pan. Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish.
  2. Season the chicken. Pat the chicken dry. Season both sides with salt, pepper, smoked paprika, and half the thyme and rosemary.
  3. Sear the chicken. Heat the olive oil in a large skillet over medium-high. Sear the chicken 3–4 minutes per side until lightly browned. It doesn’t need to be cooked through. Transfer to the baking dish.
  4. Sauté mushrooms and onions. In the same skillet, lower heat to medium. Add butter. Cook the sliced mushrooms and onions with a pinch of salt for 6–8 minutes until golden and most liquid evaporates. Stir in the garlic for 30 seconds.
  5. Make the creamy sauce. Pour in the chicken broth, scraping up browned bits. Add heavy cream, cream cheese, Dijon, and the remaining herbs. Stir until smooth and slightly thickened, 2–3 minutes. Taste and adjust salt and pepper.
  6. Assemble the bake. Spoon the mushroom mixture over the chicken. Sprinkle mozzarella and Parmesan evenly on top.
  7. Bake. Bake uncovered for 18–22 minutes, until the chicken reaches an internal temperature of 165°F (74°C) and the sauce is bubbling.
  8. Rest and garnish. Let it rest for 5 minutes so the sauce settles. Garnish with chopped parsley.
  9. Serve. Pair with a simple green salad, sautéed spinach, or roasted broccoli for a complete low-carb meal.
