Chef’s Pro Tips for Perfect Results

Want to nail this dish on your very first try? Here are some insider secrets…

• Undercook the Rice-A-Roni slightly since it’ll continue cooking in the oven
• Use rotisserie chicken for the ultimate time-saver and flavor booster
• Add a crunchy topping (like crushed Ritz or French fried onions) for texture
• Shred your own cheese—pre-shredded can be drier and less melty
• Let it rest for 5–10 minutes after baking so it sets up perfectly

Ingredients

Main Casserole

1. 1 box Chicken Rice-A-Roni
2. 2 cups cooked chicken, shredded or diced
3. 1 can (10.5 oz) cream of chicken soup
4. 1/2 cup sour cream
5. 1 cup shredded cheddar cheese (plus more for topping)
6. 1 1/2 cups water
7. 1 tbsp butter
8. 1/2 tsp garlic powder
9. 1/4 tsp black pepper
10. Optional: 1/2 cup frozen peas or mixed veggies

Topping (Optional but Recommended)

11. 1/2 cup shredded cheddar cheese
12. 1/2 cup crushed Ritz crackers or French fried onions
13. 1 tbsp melted butter (if using crackers)

Instructions

Cook the Rice

1. In a large skillet, cook the Rice-A-Roni according to the package instructions, using the butter and water, but stop cooking 2–3 minutes early so it stays slightly underdone.

Mix the Filling

2. In a large bowl, combine the cooked rice, chicken, cream of chicken soup, sour cream, 1 cup shredded cheddar, garlic powder, pepper, and peas (if using). Mix until everything is well coated.

Assemble the Casserole

3. Preheat your oven to 350°F (175°C).
4. Spread the mixture into a greased 9×13-inch baking dish.
5. Top with more shredded cheese and either crushed Ritz mixed with melted butter, or French fried onions.

Bake

6. Bake uncovered for 25–30 minutes, or until hot and bubbly and the topping is golden brown.

Rest and Serve

7. Let the casserole rest for 5–10 minutes before serving to thicken up.
