Ingredients

For this Rice a Roni Chicken Casserole, you’ll need:

• 2 boxes (6.9 oz each) Chicken Rice-a-Roni
• 4 tablespoons butter, divided
• 3 cups water
• 2 cups cooked chicken, diced or shredded (about 2 medium breasts)
• 1 can (10.5 oz) cream of chicken soup
• 1 cup sour cream
• 1/2 cup milk
• 1 cup cheddar cheese, shredded, plus 1/2 cup for topping
• 1 cup frozen peas and carrots
• 1/2 cup onion, finely diced
• 1 teaspoon garlic powder
• 1/2 teaspoon dried thyme
• 1/4 teaspoon black pepper
• 1/2 cup panko breadcrumbs
• 2 tablespoons fresh parsley, chopped (for garnish)

The Rice-a-Roni provides the signature herb-infused rice and pasta blend that forms this casserole’s foundation. For the chicken, rotisserie chicken offers excellent flavor and convenience, though any cooked chicken works beautifully.

Pro Tips

Toasting the Rice Mix: The secret to maximizing the Rice a Roni Chicken Casserole flavor starts with properly toasting the dry rice mix in butter. Take your time with this step – about 2-3 minutes until the pasta pieces turn golden brown and smell nutty. This develops a depth of flavor that elevates the entire dish beyond its humble boxed origins.

Managing Moisture Balance: The perfect casserole texture requires careful liquid control. If using rotisserie chicken that’s particularly moist, reduce the milk by 2 tablespoons. Conversely, if your casserole looks dry before baking, add an extra splash of milk. Remember that the vegetables will release some moisture during cooking.

Creating the Perfect Topping: For that irresistible golden crust, mix the final cheese and panko with 1 tablespoon of melted butter before sprinkling over the casserole. In the last 2 minutes of baking, switch to the broiler setting to achieve a beautifully browned, crispy top layer that provides textural contrast to the creamy filling below.

Instructions

Step 1: Prepare the Rice-a-Roni Base
In a large skillet over medium heat, melt 3 tablespoons of butter. Add the dry Rice-a-Roni (rice and pasta) from both boxes, discarding the seasoning packets. Toast the mixture, stirring frequently, until the pasta pieces turn golden brown, about 2-3 minutes. This toasting process creates a nutty flavor foundation for your Rice a Roni Chicken Casserole.

Step 2: Cook the Rice Mixture
Add 3 cups of water and the contents of both seasoning packets to the toasted rice mixture. Stir well, bring to a boil, then reduce heat to low. Cover and simmer for about 15 minutes, or until most of the liquid is absorbed but the rice is still slightly underdone (it will finish cooking in the oven). Remove from heat and let stand, covered, for 5 minutes.

Step 3: Preheat and Prepare
While the rice cooks, preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish. In a large bowl, combine the cream of chicken soup, sour cream, and milk, whisking until smooth.

Step 4: Combine Ingredients
Add the cooked chicken, partially cooked Rice-a-Roni, frozen peas and carrots, diced onion, garlic powder, thyme, black pepper, and 1 cup of shredded cheddar to the soup mixture. Gently fold everything together until well combined. The mixture should be creamy and well-integrated, with the Rice-a-Roni evenly distributed throughout.

Step 5: Assemble and Bake
Transfer the mixture to your prepared baking dish, spreading it evenly. In a small bowl, combine the remaining 1/2 cup cheddar, panko breadcrumbs, and remaining 1 tablespoon of melted butter. Sprinkle this topping evenly over the casserole. Cover with foil and bake for 25 minutes, then remove foil and bake for an additional 10-15 minutes until bubbly and golden brown on top.

Step 6: Rest and Serve
Allow the Rice a Roni Chicken Casserole to rest for 5-10 minutes before serving. This resting period helps the casserole set and makes serving cleaner and easier. Garnish with fresh chopped parsley before bringing to the table.

Variations

Broccoli Cheddar Version: Transform this Rice a Roni Chicken Casserole into a broccoli cheddar delight by substituting the peas and carrots with 2 cups of lightly steamed broccoli florets. Use sharp cheddar cheese instead of mild, and add 1/4 teaspoon of nutmeg to the creamy mixture. This variation offers a popular flavor combination that children and adults alike will enjoy.

Southwest Style: Create a zesty twist by using Beef Rice-a-Roni instead of chicken flavor. Replace the peas and carrots with 1 cup of corn kernels and 1 cup of black beans (drained and rinsed). Add 1 diced red bell pepper, 1 teaspoon of cumin, 1/2 teaspoon of chili powder, and substitute pepper jack for the cheddar cheese. Top with crushed tortilla chips instead of panko for authentic southwest flair.

Vegetarian Option: For a meatless version, omit the chicken and use vegetable broth instead of water when cooking the Rice-a-Roni. Increase the vegetables to 2 cups and add 1 cup of sautéed mushrooms. Use cream of mushroom or cream of celery soup instead of chicken. This hearty vegetarian adaptation maintains the comforting essence of the original.

Storage and Serving

This Rice a Roni Chicken Casserole stores beautifully, making it perfect for meal prep. Refrigerate leftovers in an airtight container for up to 4 days. For longer storage, portion the casserole into freezer-safe containers and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating. For best results, reheat refrigerated portions in a 350°F oven for 15-20 minutes or until heated through, adding a tablespoon of water or milk to maintain moisture.

Serve this casserole with a crisp green salad dressed with a light vinaigrette to balance the richness of the dish. For a complete meal, add steamed green beans or roasted asparagus on the side. Warm dinner rolls or buttery garlic bread make excellent companions to soak up the creamy sauce.

For an elegant presentation, serve individual portions in ramekins topped with additional fresh herbs and a light dusting of paprika.
