Ingredients

Scale

Chicken and Vegetables

  • 2 cups cooked chicken, shredded or diced
  • 8 ounces mushrooms, sliced (button or cremini)
  • 4 cloves garlic, minced

Dairy and Cheese

  • 1 cup heavy cream
  • 1 cup shredded mozzarella cheese
  • 1/2 cup grated Parmesan cheese

Seasonings and Oil

  • 1 tablespoon olive oil
  • 1 teaspoon dried thyme
  • 1 teaspoon dried oregano
  • Salt and pepper to taste
  • 2 tablespoons fresh parsley, chopped (for garnish)

Instructions

  1. Preheat Oven: Preheat your oven to 375°F (190°C) to prepare for baking the casserole.
  2. Sauté Mushrooms: Heat olive oil in a large skillet over medium heat. Add the sliced mushrooms and sauté for 5-7 minutes until they are golden brown and have released their moisture.
  3. Add Garlic: Stir in the minced garlic and cook for 1-2 minutes until fragrant, making sure to stir continuously to prevent burning.
  4. Combine Ingredients: In a large mixing bowl, mix together the cooked chicken, sautéed mushrooms and garlic, heavy cream, dried thyme, dried oregano, salt, and pepper until evenly combined.
  5. Assemble Casserole: Transfer the mixture into a greased 9×13-inch casserole dish, spreading it evenly across the bottom.
  6. Add Cheese Topping: Generously sprinkle shredded mozzarella and grated Parmesan cheese on top of the chicken mixture.
  7. Bake: Place the casserole dish into the preheated oven and bake for 25-30 minutes until the cheese is bubbly and golden brown.
  8. Garnish and Serve: Remove the casserole from the oven and let it cool slightly. Garnish with freshly chopped parsley before serving.

Notes

  • For a crustier top, broil the casserole for an additional 2-3 minutes after baking.
  • Use rotisserie chicken or shredded turkey as alternative proteins.
  • For a vegetarian version, substitute chicken with chickpeas or tofu.
  • Mushrooms provide antioxidants and vitamins D and B, boosting nutritional value.
