Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

• Box(es) of Rice-a-Roni (chicken-flavored or your favorite)

• Boneless, skinless chicken breasts or thighs, cut into bite-sized pieces

• Chicken broth

• Milk or half-and-half

• Butter or oil

• Onion, diced

• Garlic, minced

• Frozen peas and carrots (optional)

• Salt and pepper

• Shredded cheese (cheddar, Monterey Jack, or a blend)

Directions

1. Preheat oven. Preheat to 375 °F (190 °C).

2. Cook the rice base. In a large skillet over medium heat, melt butter or warm oil. Add diced onion and sauté until translucent, then add garlic for about 30 seconds.

3. Toast with seasoning. Add the Rice-a-Roni rice and seasoning packet; cook, stirring, for 2–3 minutes until the rice is lightly toasted.

4. Add liquids and chicken. Stir in the chicken broth and milk, then add the chicken pieces. Bring to a gentle boil, stirring to combine.

5. Add veggies (optional). Stir in frozen peas and carrots if using.

6. Transfer to casserole dish. Pour the mixture into a greased 9×13-inch baking dish, spreading evenly.

7. Bake. Cover with foil and bake for about 20 minutes. Remove foil, sprinkle shredded cheese on top, then bake an additional 10 minutes, or until cheese is melted and bubbly.

8. Rest and serve. Let the casserole rest for 5 minutes before serving to allow it to set.

Servings and Timing

• Servings: Serves 6–8

• Prep time: 10 minutes

• Cook time: 10 minutes stovetop + 30 minutes baking

• Total time: Approximately 40 minutes

Variations

• Cream of soup twist: Substitute the milk with cream of chicken or mushroom soup for a richer, creamier texture.

• Spicy version: Add a can of diced green chilies or stir in a dash of hot sauce for a little kick.

• Veggie boost: Include broccoli florets, bell peppers, or mushrooms along with peas and carrots.

• Crunchy topping: After baking, sprinkle crushed buttery crackers or breadcrumbs mixed with melted butter and broil for 2–3 minutes until golden and crisp.

Storage/Reheating

Store leftovers in an airtight container in the fridge for up to 4 days. To reheat, warm individual portions in the microwave (covered, in 30-second intervals) or bake in a small oven-safe dish at 350 °F (175 °C) for 15–20 minutes, adding a splash of milk if it seems dry.

FAQs

1. Can I use leftover cooked chicken instead of raw pieces?

Yes! I often toss in shredded cooked chicken during the final baking stage—just reduce the initial stovetop simmer and go straight to baking once everything’s combined.

2. What other Rice-a-Roni flavors can I use?

I like trying cheddar and sour cream-and-chive flavors too—they each bring a different taste profile and work well with this casserole base.

3. Can I freeze this casserole?

Absolutely. I cool it completely, wrap tightly, and freeze for up to 2 months. Thaw in the fridge overnight, then bake at 350 °F until heated through (about 30–35 minutes).

4. Is this gluten-free?

Not as written, since Rice-a-Roni contains wheat. For a gluten-free version, I substitute with a rice-and-seasoning mix that’s certified gluten-free.

5. Can I make this in advance?

Yes! I assemble everything in the casserole dish, cover, and refrigerate. On baking day, I just pop it into the oven (adding cheese near the end) and dinner’s ready.

Conclusion

This Chicken Rice-a-Roni Casserole is a comforting, easy-to-make staple that never disappoints. With minimal effort, it delivers hearty flavor and satisfying textures. Whether feeding a family or meal prepping, it’s a dependable favorite in my kitchen.
