Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures that the casserole will bake evenly, resulting in a perfectly golden, melted cheese topping.
Step 2: Season and Sear the Chicken
- Cut the chicken breasts into bite-sized pieces and season them with Italian seasoning, salt, and pepper.
- In a large pot, melt the butter over medium heat.
- Add the chicken pieces and cook until they are golden brown on all sides, approximately 5 minutes. This step not only cooks the chicken but also develops a beautiful golden crust that adds a depth of flavor.
Step 3: Cook the Rice
- To the same pot, add the chicken broth, olive oil, and uncooked white rice.
- Bring the mixture to a boil, then reduce the heat to a simmer. Cover the pot and cook for 6 minutes.
- Add the broccoli florets, cover, and continue to cook for another 9 minutes or until the liquid is fully absorbed and the rice is cooked through.
Tip: If the rice isn’t fully cooked, continue to simmer for an additional 5 minutes. Keeping the lid on during this stage traps the steam, which helps to cook the rice evenly.
Step 4: Rest and Fluff the Rice
- Turn off the heat and leave the pot covered for 10 minutes. This resting period allows the rice to finish cooking and absorb any remaining liquid, making it fluffy and preventing it from sticking together.
Step 5: Combine Ingredients
- Stir in the cooked chicken, cream of chicken soup, milk, sour cream, and half of the shredded cheddar cheese.
- The creamy mixture coats the rice and broccoli, infusing each bite with rich, savory flavors.
Step 6: Transfer to Casserole Dish
- Transfer the mixture to a lightly greased 9×13-inch casserole dish.
- Sprinkle the remaining cheddar cheese on top, covering the surface evenly.
Step 7: Bake
- Cover the dish with aluminum foil and bake in the preheated oven for 15 minutes.
- This baking time allows the cheese to melt and the flavors to meld together beautifully.
