Preheat your oven to 350°F (175°C). Lightly grease a 9x13 inch baking dish with non stick cooking spray.
2. Prepare the Casserole Mixture:
In a large mixing bowl, combine uncooked rice, shredded chicken, cream of mushroom soup, cream of chicken soup, chicken broth, sour cream, garlic powder, onion powder, dried thyme, salt, and black pepper.
Add shredded cheddar cheese and frozen peas and carrots if using. Mix well to combine.
3. Assemble the Casserole:
Pour the mixture into the prepared baking dish and spread it evenly.
4. Optional Topping:
In a small bowl, mix panko breadcrumbs with melted butter until evenly coated.
Sprinkle the breadcrumb mixture over the top of the casserole.
5. Bake:
Cover the baking dish with aluminum foil and bake for 30 minutes.
Remove the foil and bake for an additional 20-25 minutes, or until the rice is tender and the top is golden brown.
6. Serve:
Let the casserole rest for 5 minutes before serving.
Garnish with fresh parsley if desired and serve warm.
Notes
Rice Type: Use long grain white rice for best results. Avoid instant rice as it may become too soft.
Vegetable Add Ins: You can add mushrooms, green beans, or broccoli for extra nutrients.
Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave before serving.
Make-Ahead Option: Assemble the casserole up to 24 hours in advance and refrigerate. Add 10-15 minutes to the baking time if baking from cold.
