Ingredients
- 4 boneless, skinless chicken breasts
Chicken breasts are the star of this dish, providing a lean protein that pairs well with the creamy sauce. They absorb the flavors of the surrounding ingredients and stay tender when baked. - 8 ounces mushrooms, sliced
Mushrooms add depth and umami to the casserole, enhancing its overall flavor profile. Their meaty texture complements the chicken, making every bite interesting. - 1 cup uncooked rice
The rice acts as a base for the casserole, soaking up the flavorful sauce as it cooks. It also adds heartiness to the dish, making it a complete meal. - 1 can cream of mushroom soup (10.5 ounces)
This canned soup serves as the creamy backbone of the casserole, effortlessly tying together the ingredients. It adds richness and moisture while helping to cook the rice. - 1 cup shredded cheddar cheese
Cheddar cheese lends its melty goodness to the dish, giving it that comforting cheesy appeal. Its sharp flavor contrasts beautifully with the richness of the creamy sauce. - 1/2 cup milk
Milk thins out the sauce, contributing to the creamy texture of the casserole. It integrates with the soup, ensuring that each ingredient is evenly coated. - 1 teaspoon garlic powder
Garlic powder infuses the casserole with aromatic flavor, complementing the chicken and mushrooms without overpowering them. - Salt and pepper to taste
These seasonings are essential for enhancing the natural flavors of the ingredients. Adjust them based on your preference to get the perfect balance. - 1 tablespoon olive oil
Olive oil is used to sauté the mushrooms initially, helping them to soften and release their flavors before they’re combined with the other ingredients.
Directions & Preparation
Step 1: Preheat the oven to 375°F (190°C).
Preheating is crucial for even cooking, as it ensures that the casserole will bake properly from the moment you place it in the oven. A well-prepped oven allows the chicken to cook through, resulting in juicy pieces that aren’t dried out.
Step 2: Heat olive oil in a large skillet over medium heat. Sauté the sliced mushrooms for about 5-7 minutes until they are golden and tender.
Sautéing the mushrooms first enhances their flavor through caramelization. This step also helps reduce excess moisture, preventing the casserole from becoming soggy. Stir occasionally to ensure even browning.
Step 3: In a large mixing bowl, combine the cream of mushroom soup, milk, garlic powder, salt, and pepper. Mix until smooth.
Combining the soup with milk creates a creamy base that evenly coats the chicken and rice. The garlic powder and seasoning should be well incorporated for uniform flavor throughout the casserole.
Step 4: In a greased 9×13 inch casserole dish, layer the uncooked rice on the bottom. Scatter the sautéed mushrooms and chicken breasts over the rice.
Layering the ingredients helps ensure that the rice cooks evenly and absorbs the liquid from the sauce and the chicken drippings. The chicken, placed on top, will baste itself in the sauce while baking, keeping it moist.
Step 5: Pour the soup mixture evenly over the chicken and rice, ensuring that everything is covered.
This step is crucial because it creates the moist environment needed for the rice to cook properly. The soup will soak into the rice and infuse it with flavor, making every bite delightful.
Step 6: Sprinkle the shredded cheddar cheese over the top of the casserole.
Adding cheese on top not only enhances the appearance but also contributes a delicious crust as it melts and browns in the oven. It adds that extra touch of comfort that everyone loves.
Step 7: Cover the casserole dish with aluminum foil and bake in the preheated oven for 45 minutes.
Covering it prevents the cheese from burning and retains moisture, allowing the rice to cook through. This initial steam will help ensure an evenly cooked casserole.
Step 8: Remove the foil and bake for an additional 15 minutes, or until the cheese is bubbly and golden.
This final uncovered baking allows the cheese to develop a beautiful top layer and ensures the casserole is cooked through. The bubbling indicates that the dish is ready to serve.
Step 9: Let the casserole sit for 5-10 minutes before serving, allowing the flavors to meld and the casserole to set.
Resting time is essential as it lets the dish stabilize, making serving easier and enhancing the overall flavor. The casserole continues to cook slightly from residual heat, ensuring everything is well combined.

Elevate Your Casserole with Fresh Herbs
Incorporating fresh herbs such as thyme or parsley can really elevate this cheesy baked chicken and mushroom casserole. Fresh herbs add a pop of color and a fragrant note that can brighten the dish. Simply chop them finely and mix them into the soup or sprinkle them over the top before serving for an extra layer of flavor.
Variations for the Adventurous Cook
Feel free to customize your casserole with different vegetables or proteins. Swap the chicken for turkey or even add in some broccoli or spinach for a nutritional boost. If you prefer spices, a pinch of red pepper flakes or Cajun seasoning can add an exciting kick to the dish, catering to diverse palates.
Perfect Pairings: Sides and Salads
This casserole pairs beautifully with a simple green salad or some steamed vegetables. A fresh Caesar salad with its crisp textures and tangy dressing balances the creamy richness of the casserole, making for a well-rounded meal. Crusty bread is also a great accompaniment for soaking up the delicious sauce.
FAQs
What should I do if my casserole turns out too thick?
If your casserole is too thick, add a splash of chicken broth or milk to thin out the mixture during baking. Stir gently to incorporate the liquid into the other components.
How can I adjust the recipe for a larger group?
To scale the recipe for more servings, simply double the ingredients and use a larger baking dish. Ensure the baking time is adjusted for larger quantities, checking for doneness periodically.
What if the chicken seems overcooked when I take it out?
If the chicken seems overcooked, it may have been exposed to heat for too long. To avoid this in the future, buy thinner chicken cutlets or reduce the baking time slightly, watching for juiciness.
Can I use frozen chicken for this casserole?
Yes, you can use frozen chicken, but it’s essential to thaw it completely beforehand to ensure even cooking. Cook time may increase, so make sure to check for doneness.
Why does my casserole seem bland?
If your casserole lacks flavor, ensure you’re seasoning each layer adequately. Also, consider adding a splash of hot sauce or a dash of lemon juice to brighten up the flavors.
What kind of mushrooms work best in this dish?
While button mushrooms are a classic choice, feel free to experiment with cremini or shiitake mushrooms for a richer flavor profile.
