1️⃣ Preheat the oven and prepare the dish: Begin by preheating your oven to 350°F (175°C). Lightly grease a 9×13-inch casserole dish with non-stick cooking spray.
2️⃣ Soften the butter and cream cheese: In a microwave-safe bowl, combine the butter and cream cheese. Heat in the microwave for 20-30 seconds until softened. Whisk until smooth and well combined.
3️⃣ Prepare the casserole base: In a large mixing bowl, combine the cooked chicken, cooked rice, softened butter and cream cheese mixture, cream of chicken soup, minced garlic, Italian dressing mix, chicken stock, and half of the shredded Colby Jack cheese. Season with salt and pepper to taste. Stir until everything is well integrated.
4️⃣ Transfer to casserole dish: Pour the chicken and rice mixture into the prepared casserole dish, spreading it out evenly.
5️⃣ Top with cheese: Sprinkle the remaining shredded Colby Jack cheese evenly over the top of the casserole.
6️⃣ Bake the casserole: Cover the casserole with aluminum foil and bake in the preheated oven for 20-25 minutes, or until the cheese is melted and the casserole is bubbly around the edges.
7️⃣ Finish and serve: After baking, remove the casserole from the oven and let it rest for 5 minutes. Remove the foil, garnish with fresh parsley, and serve while warm.
