Creating Angel Chicken Rice is a straightforward process. Follow these steps for the desired results:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking dish with olive oil.
2. Prepare the Chicken: Season the chicken breasts with salt and pepper. Place them at the bottom of the greased baking dish.
3. Mix the Rice: In a bowl, combine the long-grain rice, chicken broth, and ranch dressing mix. Stir well to mix all the ingredients.
4. Add Mushrooms: Sprinkle the sliced mushrooms over the chicken in the baking dish.
5. Layer the Rice Mixture: Pour the rice mixture over the chicken and mushrooms, making sure it covers evenly.
6. Combine Soup and Cheese: In another bowl, mix the cream of chicken soup with half of the shredded cheddar cheese.
7. Spread the Mixture: Spread the cream of chicken mixture over the rice layer in the baking dish.
8. Cover and Bake: Cover the dish with aluminum foil and bake for 30 minutes.
9. Remove Foil: After 30 minutes, remove the foil and sprinkle the remaining cheddar cheese on top.
10. Bake Uncovered: Return the dish to the oven and bake uncovered for an additional 15 minutes, or until the cheese is melted and bubbly.
11. Serve and Enjoy: Once done, let it rest for about 5 minutes before serving. Garnish with chopped parsley for a burst of color and flavor.
