Ingredients

Scale
  • 4 boneless, skinless chicken breasts
  • 2 cups fresh spinach (chopped)
  • 1 cup mushrooms (sliced)
  • 1/2 cup shredded mozzarella cheese
  • 1/4 cup grated Parmesan cheese
  • 1/2 cup heavy cream
  • 1 tablespoon olive oil (for sautéing)
  • 2 cloves garlic, minced
  • 1 teaspoon dried oregano
  • 1 teaspoon garlic powder
  • Salt and pepper to taste
  • 1/2 teaspoon red pepper flakes (optional, for extra flavor)
  • Fresh parsley for garnish (optional)

Instructions

  • Preheat the oven: Preheat your oven to 375°F (190°C) and grease a 9×13-inch baking dish.
  • Prepare the chicken: Season the chicken breasts with salt, pepper, garlic powder, and dried oregano on both sides.
  • Sauté the mushrooms and spinach: In a large skillet, heat the olive oil over medium heat. Add the sliced mushrooms and sauté for 4-5 minutes, until softened. Add the minced garlic and cook for an additional 1 minute. Then add the spinach and cook until wilted, about 2-3 minutes. Remove from heat and set aside.
  • Make the sauce: In a small bowl, mix the heavy cream with grated Parmesan cheese. Stir until smooth and well combined.
  • Assemble the dish: Place the seasoned chicken breasts in the prepared baking dish. Spoon the sautéed spinach and mushrooms evenly over the chicken. Pour the heavy cream mixture over the chicken and vegetables. Sprinkle shredded mozzarella cheese on top.
  • Bake: Bake the dish in the preheated oven for 25-30 minutes, or until the chicken is cooked through (internal temperature should reach 165°F/74°C) and the cheese is melted and bubbly.
  • Serve: Remove from the oven and let it rest for 

Notes

  • You can use chicken thighs instead of breasts for a juicier option.
  • For extra flavor, add a squeeze of lemon juice before serving.
  • This dish pairs well with a side of cauliflower rice or steamed vegetables for a low-carb meal.
  • Can be made ahead and stored in the fridge for up to 4 days.
