1. **Preheat the Oven:**
– Preheat your oven to 375°F (190°C).
2. **Prepare the Casserole Mix:**
– In a large mixing bowl, combine the cream of chicken soup, sour cream, milk, garlic powder, onion powder, salt, pepper, and thyme (if using). Stir until well mixed.
3. **Combine Ingredients:**
– Add the uncooked rice, diced chicken, shredded cheddar cheese, and frozen peas and carrots to the bowl. Mix until everything is evenly coated with the soup mixture.
4. **Transfer to Baking Dish:**
– Grease a 9×13-inch baking dish. Pour the casserole mixture into the dish and spread it out evenly.

6. **Bake:**

– After 45 minutes, remove the foil and bake for an additional 10-15 minutes, or until the top is golden brown and the casserole is bubbly.
7. **Cool and Serve:**
– Let the casserole cool for a few minutes before serving. This allows the flavors to meld and makes it easier to serve.
