Directions:
Preheat oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
In a large bowl, combine shredded chicken, frozen mixed vegetables, uncooked rice, cream of chicken soup, milk, minced garlic, onion powder, Italian seasoning, salt, and black pepper. Stir well until evenly combined.
Pour the mixture into the prepared baking dish and spread it out evenly.
Cover tightly with foil and bake for 25 minutes, allowing the rice to cook and absorb the creamy mixture.
Remove foil and sprinkle shredded Colby Jack cheese evenly over the top.
Return to the oven and bake for another 10–15 minutes, until the cheese is melted, bubbly, and lightly golden around the edges.
Let the casserole rest for a few minutes before serving to allow it to set.
