  • Total Time: 45 minutes
  • Yield: 6 servings

Ingredients

  • 1 teaspoon thyme
  • 2 cups cooked chicken, shredded or diced
  • 2 cups sliced mushrooms
  • 1 cup heavy cream
  • 1 cup chicken broth
  • 1/2 cup cream cheese, softened
  • 2 cups shredded mozzarella cheese, divided
  • 1/2 cup parmesan cheese
  • 2 cloves garlic, minced
  • Salt and pepper to taste
  • 2 tablespoons olive oil
  • 1/2 cup chopped spinach (optional)
  • 1/4 teaspoon red pepper flakes (optional)

Instructions

  1. Preheat oven to 375°F (190°C) and grease a casserole dish with olive oil.
  2. In a skillet, heat 2 tablespoons olive oil over medium heat. Sauté sliced mushrooms for 5–7 minutes until golden, then add garlic and cook for 1 more minute. Remove from heat.
  3. In a bowl, whisk together heavy cream, chicken broth, and cream cheese until smooth. Season with thyme, salt, and pepper.
  4. Fold in cooked chicken, sautéed mushrooms, spinach, and red pepper flakes (if using).
  5. Pour mixture into the greased casserole dish and spread evenly. Top with 1 cup of shredded mozzarella.
  6. In a small bowl, combine remaining mozzarella and parmesan cheese. Sprinkle over the casserole.
  7. Bake uncovered for 25–30 minutes until bubbly and golden on top. Broil for 1–2 minutes if a crispier top is desired.
  8. Let rest for 5 minutes before serving.

Notes

  • Use cheddar cheese instead of mozzarella for a stronger flavor.
  • Add a pinch of rosemary along with thyme for extra depth.
  • Substitute turkey for chicken if desired.
  • Use almond milk instead of cream for a lighter version.
  • Store in fridge for up to 4 days or freeze for up to 2 months.
