Step-by-Step Instructions
Prepare the Chicken
Preheat the oven to 375°F (190°C).
Cut the chicken breasts into bite-sized pieces.
Pat the chicken dry with paper towels.
Season with salt, black pepper, paprika, garlic powder, and Italian seasoning.
Toss well so the seasoning coats the chicken evenly.
Brown the Chicken
Heat olive oil in a large skillet over medium-high heat.
Add the seasoned chicken pieces.
Cook for approximately 4–5 minutes, stirring occasionally, until lightly browned on the outside.
The chicken does not need to be completely cooked at this stage because it will finish cooking in the oven.
Transfer the chicken to a plate.
Cook the Mushrooms and Onion
Reduce the skillet heat to medium.
Add the butter.
Once melted, add the diced onion and sliced mushrooms.
Cook for approximately 5–7 minutes until the onion softens and the mushrooms release their moisture.
Add the minced garlic.
Cook for another 30 seconds until fragrant.
Prepare the Creamy Mixture
In a large bowl, combine the cream of mushroom soup, sour cream, heavy cream, Parmesan cheese, and chicken broth.
Whisk until smooth.
Taste and adjust the seasoning if needed.
Assemble the Casserole
Lightly grease a 9 × 13-inch baking dish.
Add the uncooked rice to the bottom of the dish.
Spread the cooked mushrooms and onions over the rice.
Add the browned chicken pieces.
Pour the creamy sauce evenly over everything.
Gently stir the mixture so the rice is evenly distributed and covered with liquid.
Bake
Cover the baking dish tightly with aluminum foil.
Bake for approximately 35 minutes.
Carefully remove the foil and check the rice.
If the rice needs additional time, cover again and continue baking for 5–10 minutes.
Add the Cheese
Once the rice is tender and the chicken is cooked through, remove the foil.
Sprinkle the mozzarella evenly over the top.
Add the remaining Parmesan.
Return the casserole to the oven uncovered.
Bake for another 8–10 minutes until the cheese is melted and bubbling.
For a more golden topping, broil for 1–2 minutes while watching carefully.
Rest and Garnish
Remove the casserole from the oven.
Let it rest for approximately 5–10 minutes.
Sprinkle generously with fresh chopped parsley.
Serve hot while the cheese is still stretchy and melted.
Best Tips
Use long-grain white rice for the most reliable texture.
Avoid rinsing the rice if you want the casserole to retain a creamy consistency.
Cut the chicken into evenly sized pieces so everything cooks at the same rate.
Sauté the mushrooms before baking to remove excess moisture and deepen their flavor.
Keep the casserole covered during most of the baking time so the rice cooks properly.
Add the cheese toward the end to achieve a golden, creamy topping instead of overcooking it.
Best Ingredient Options
Chicken
Boneless chicken breasts are lean and easy to cut into bite-sized pieces.
Boneless chicken thighs are an excellent alternative when you want a richer and more tender result.
Rice
Long-grain white rice works particularly well.
Basmati rice can add a pleasant aroma, while jasmine rice gives the casserole a softer texture.
Avoid using quick-cooking rice unless the liquid and cooking time are adjusted according to the package directions.
Mushrooms
White button mushrooms are convenient and mild.
Cremini mushrooms provide a deeper earthy flavor.
A combination of cremini and shiitake mushrooms can create an even richer mushroom flavor.
Cheese
Mozzarella provides the best stretchy topping.
Provolone, Monterey Jack, cheddar, or a combination of mozzarella and Parmesan can also be used.
Recipe Variations
Garlic Parmesan Chicken Rice Bake
Add extra minced garlic and Parmesan to the creamy sauce for a stronger garlic-cheese flavor.
Broccoli Chicken Rice Casserole
Add small broccoli florets during the final part of the baking process.
Spinach Mushroom Chicken Bake
Stir fresh baby spinach into the creamy mixture before baking.
Spicy Chicken Rice Bake
Add crushed red pepper flakes, cayenne pepper, or diced jalapeños.
Bacon Mushroom Chicken Bake
Add cooked, crumbled bacon to the casserole before topping it with cheese.
What to Serve With
This creamy chicken and rice bake is filling enough to serve as a complete meal.
A crisp green salad provides a fresh contrast to the creamy casserole.
Steamed broccoli, green beans, or roasted asparagus also make excellent side dishes.
Crusty garlic bread is perfect for scooping up any remaining creamy sauce.
Make-Ahead Instructions
You can prepare the chicken, mushroom mixture, and creamy sauce several hours ahead.
Store everything covered in the refrigerator.
For the best results, assemble the casserole shortly before baking so the uncooked rice does not absorb too much liquid before it reaches the oven.
If assembling the entire casserole ahead of time, keep it refrigerated and bake it within 24 hours.
Add additional baking time if the casserole is very cold when it goes into the oven.
Storage
Allow leftovers to cool before transferring them to an airtight container.
Refrigerate for up to 4 days.
Individual portions are convenient for quick lunches and easy meal prep.
Reheating
Reheat individual portions in the microwave for 1–3 minutes.
Add a small splash of chicken broth or cream if the rice appears dry.
For larger portions, reheat covered in a 350°F (175°C) oven until hot throughout.
Freezing
Allow the casserole to cool completely before freezing.
Transfer individual portions to freezer-safe containers.
Freeze for up to 2 months for the best quality.
Thaw overnight in the refrigerator before reheating.
Because creamy rice can become slightly softer after freezing, reheating gently helps preserve the texture.
Common Mistakes to Avoid
Using the Wrong Rice
Different rice varieties require different amounts of liquid and cooking time.
Long-grain white rice is the safest choice for this recipe.
Skipping the Mushroom Sauté
Adding raw mushrooms directly to the casserole can introduce excess moisture.
Sautéing them first creates deeper flavor and a better texture.
Adding Cheese Too Early
Cheese can become overly browned before the rice finishes cooking.
Add it during the final stage.
Not Covering the Casserole
The foil traps steam and helps the rice cook evenly.
Leaving the casserole uncovered for the entire baking time can result in undercooked rice.
Cutting the Chicken Too Large
Large chicken pieces take longer to cook.
Bite-sized pieces distribute throughout the casserole and cook more evenly.

Frequently Asked Questions
Can I use chicken thighs?
Yes. Boneless, skinless chicken thighs are an excellent substitute for chicken breasts.
Can I use brown rice?
Brown rice requires more liquid and a longer cooking time, so it should not be substituted directly without adjusting the recipe.
Can I use leftover cooked chicken?
Yes. Add the cooked chicken later in the process so it does not become dry.
Can I use fresh mushrooms?
Yes. Fresh mushrooms are recommended and should be sliced and sautéed before assembling the casserole.
Can I make this without cream of mushroom soup?
Yes. You can make a homemade mushroom cream sauce using butter, flour, chicken broth, milk or cream, and sautéed mushrooms.
Can I add vegetables?
Absolutely. Broccoli, spinach, peas, green beans, and bell peppers all work well.
How do I get the cheese perfectly golden?
Bake the casserole uncovered during the final stage, then broil for 1–2 minutes if necessary.
Watch carefully because the cheese can brown very quickly.
