Making the Creamy Mushroom Chicken & Rice Casserole is a straightforward process. Follow these steps to create your comforting masterpiece:

1. Preheat the Oven: First, preheat your oven to 350°F (175°C).
2. Prepare the Rice: Cook the rice according to package instructions. Set aside once cooked.
3. Sauté the Chicken: In a large skillet, heat olive oil over medium heat. Add the cubed chicken, and cook until browned and cooked through, about 5-7 minutes. Remove the chicken from the skillet and set aside.
4. Sauté the Vegetables: In the same skillet, add chopped onion and sauté until translucent, about 3 minutes. Then add minced garlic and sliced mushrooms, cooking until mushrooms are soft.
5. Combine Ingredients: Return the cooked chicken to the skillet, and stir in cooked rice, chicken broth, heavy cream, thyme, paprika, salt, and black pepper. Mix until well combined.
6. Transfer to Casserole Dish: Pour the mixture into a greased 9×13-inch casserole dish.
7. Cheese Topping: Sprinkle shredded cheese over the top of the casserole mixture.
8. Bake: Cover the dish with aluminum foil and bake for 30 minutes. Remove the foil and bake for an additional 15 minutes or until bubbly and golden on top.
9. Garnish: Remove from the oven and let it sit for about 5 minutes. Garnish with fresh parsley before serving.
