This chicken rice casserole has been my family's go-to comfort meal for years, combining creamy rice, tender chicken, and gooey cheese in one satisfying dish that brings everyone to the table with smiles.
I first discovered this recipe during a particularly hectic week when I needed something simple yet satisfying. What started as a convenient solution quickly became our most requested family dinner, especially during the colder months when we crave something warm and comforting.
Ingredients
- Long grain white rice: absorbs flavors beautifully without becoming mushy look for American-grown varieties for best results
- Cream of chicken or mushroom soup: provides rich creaminess without extra work choose low-sodium versions if watching salt intake
- Water: helps cook the rice to perfect tenderness filtered water yields best results
- Milk: creates silky texture throughout the casserole whole milk makes it richer but 2% works well too
- Onion soup mix: adds depth of flavor without chopping shop for varieties without MSG for cleaner flavor
- Shredded cheddar cheese: creates that irresistible golden top sharp cheddar provides more flavor impact
- Boneless skinless chicken breasts: remain tender and juicy throughout baking select thick even-sized pieces for consistent cooking
- Salt and pepper: enhances all other flavors adjust according to taste preferences
Step-by-Step Instructions
- Prepare Your Baking Dish:
- Preheat your oven to 350°F and thoroughly grease a 9x13 inch baking dish with non-stick spray ensuring you cover the corners and sides where sticking is most likely to occur. This temperature allows for gentle even cooking that tenderizes the chicken while perfectly cooking the rice.
- Create Your Rice Base:
- In a large mixing bowl combine rice cream soups water milk and onion soup mix stirring until thoroughly incorporated. The mixture will seem very liquid at this stage but trust the process as the rice will absorb the liquid during baking creating a creamy texture.
- Layer The Components:
- Pour your rice mixture into the prepared baking dish spreading it evenly across the bottom. Sprinkle half the shredded cheese over the rice mixture creating a middle layer of cheese that will melt into creamy pockets throughout the casserole.
- Add The Protein:
- Place your chicken breasts gently on top of the rice and cheese mixture pressing them slightly into the liquid but not completely submerging them. Position them evenly throughout the dish so each serving will include chicken.
- Cover And Bake:
- Tightly seal the baking dish with aluminum foil ensuring all edges are well crimped. This traps moisture and heat creating the perfect environment for cooking both rice and chicken to tender perfection. Place in your preheated oven and bake for 1 hour and 30 minutes to 2 hours.
- Final Touches:
- Once the rice is tender and chicken is fully cooked remove the foil and sprinkle the remaining cheese evenly over the top. The residual heat will melt the cheese creating a beautiful golden topping without overcooking the dish.
- Rest Before Serving:
- Allow the casserole to rest uncovered for 15-20 minutes before serving. This crucial step allows the excess moisture to be absorbed and the texture to set properly giving you perfect serving consistency.

The onion soup mix is my secret weapon in this recipe. My grandmother taught me this trick years ago when I complained about chopping onions, and I've never looked back. The concentrated flavor permeates every grain of rice, creating depth that would otherwise require hours of cooking.
Make-Ahead Magic
This casserole actually improves when made ahead of time. Prepare everything up to the baking step, cover tightly, and refrigerate for up to 24 hours. The resting time allows the flavors to meld beautifully. When ready to cook, simply add about 15 minutes to the baking time to account for the chilled ingredients. I often prepare this on Sunday afternoon for Monday dinner, making the start of the week much less stressful.
Freezer-Friendly Tips
For busy families, this casserole is a freezer dream. Prepare the entire recipe through the baking stage, allow to cool completely, then portion into freezer-safe containers. To reheat, thaw overnight in the refrigerator and warm in a 325°F oven until heated through, about 30 minutes. Individual portions can be microwaved for quick lunches. The texture remains remarkably good, though the rice may be slightly softer after freezing.
Customization Ideas
The beauty of this casserole lies in its versatility. For added nutrition, stir in 2 cups of frozen mixed vegetables with the rice mixture. To enhance flavor, add 1 teaspoon of garlic powder and 1 tablespoon of fresh herbs like thyme or parsley. For a more indulgent version, mix 4 ounces of cream cheese into the rice mixture before baking. You can also substitute the chicken with leftover turkey after holidays for a delicious way to repurpose leftovers.

Serving Suggestions
While this casserole stands beautifully on its own, I like to serve it with a simple side salad dressed with vinaigrette to cut through the richness. Steamed broccoli or green beans also complement the creamy texture perfectly. For special occasions, a crusty artisan bread for sopping up the creamy sauce elevates the meal to dinner-party worthy status without extra effort.
