Creating Chicken and Rice Casserole can be straightforward if you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C).
2. Prepare the Rice: In a large pot, bring the chicken broth to a boil. Add the uncooked rice, cover, and reduce the heat to low. Cook according to package instructions, usually about 15-20 minutes.
3. Cook the Chicken: While the rice cooks, heat olive oil in a skillet over medium heat. Season the chicken breasts with salt, pepper, garlic powder, and onion powder. Cook for 5-7 minutes on each side until the chicken is cooked through and no longer pink.
4. Shred the Chicken: Remove the chicken from the skillet and let it cool briefly. Shred the chicken into bite-sized pieces using two forks.
5. Mix the Ingredients: In a large bowl, combine the cooked rice, cream of chicken soup, sour cream, shredded chicken, frozen vegetables, and half the shredded cheese. Stir until well mixed.
6. Transfer to Baking Dish: Pour the mixture into a greased 9×13-inch baking dish, spreading it evenly.
7. Add Remaining Cheese: Sprinkle the remaining shredded cheese on top of the casserole.
8. Bake: Cover the dish with aluminum foil and bake in the preheated oven for 30 minutes. Remove the foil and bake for an additional 15-20 minutes until the cheese is bubbly and golden.
9. Garnish and Serve: Once baked, remove from the oven and let it cool for a few minutes. Garnish with fresh parsley if desired before serving.

These straightforward steps will guide you in creating this incredible dish effortlessly.
