This Cheesy Baked Chicken and Rice Casserole is the answer when you need a cozy, hearty meal that doubles as a family crowd-pleaser and an easy weeknight victory. It brings together tender chicken, fluffy rice, sweet mixed vegetables, and a creamy cheese sauce under a golden, crispy topping. If your household is anything like mine, the requests for second helpings will start before you even finish serving the first scoops.
The first time I baked this casserole was out of pure necessity after a long workday. It instantly became a hit and now it shows up whenever comfort is in order. There is always a little friendly debate over who gets the crunchiest corner piece.
Ingredients
- Boneless skinless chicken thighs: Choose thighs for extra juiciness and flavor. Aim for ones with a fresh, pink color and no strong aroma
- Long grain white rice: Long grain rice cooks up fluffy and distinct. Avoid short grain as it tends to get mushy in bakes
- Onion soup mix: Adds deep savory flavor with minimal effort. Opt for a reputable brand or make it homemade for less salt
- Cream of mushroom soup: Binds everything together in a rich creamy sauce. Look for one with real mushrooms listed high in the ingredient list
- Chicken broth: Enhances flavor and keeps the casserole moist. Use low sodium for better control over seasoning
- Whole milk: Introduces extra creaminess. Whole milk is key for body but two percent will work in a pinch
- Frozen mixed vegetables: Peas carrots and corn give the dish color and subtle sweetness. Use a mix without added sauces
- Sharp cheddar cheese: Brings rich tangy flavor and classic casserole melt. Pre-shredded is handy but freshly grated melts better
- Grated Parmesan cheese: Boosts umami and pairs well with cheddar
- Salt and freshly ground black pepper: Use to taste but be cautious since the soup mix and broth add salt
- Panko breadcrumbs: These create a light crispy topping. Look for golden dry panko not the finer regular breadcrumbs
- Melted butter: Ensures golden color on the topping
- Chopped fresh parsley: Finishes the dish with freshness and color
Instructions
- Preheat and Prepare the Dish:
- Preheat your oven to 375 degrees Fahrenheit. Grease a nine by thirteen inch baking dish generously with cooking spray or a thin coating of butter to prevent sticking
- Season the Chicken:
- Pat chicken thighs dry with paper towels. Cut into bite sized pieces and season lightly with salt and black pepper all over. This step ensures every bite of chicken is flavorful throughout the casserole
- Combine Base Ingredients:
- In the prepared baking dish layer chicken pieces evenly. Add uncooked long grain rice onion soup mix and frozen mixed vegetables. Gently mix so ingredients are evenly distributed. Evenness here guarantees the rice cooks properly and vegetables are spread throughout
- Create Creamy Sauce:
- In a large mixing bowl whisk together the can of cream of mushroom soup chicken broth and whole milk until smooth. Take a moment to make sure there are no lumps This helps the sauce blend into every bite instead of puddling unevenly
- Pour and Stir:
- Carefully pour the sauce over the chicken rice and veggie mixture in the dish. Stir gently with a spatula to coat all the ingredients don&t press down too much Swirl the mixture so the sauce settles into every corner and under all the rice
- Add Cheese:
- Sprinkle one and a half cups of shredded sharp cheddar and all of the grated Parmesan cheese evenly across the casserole. This early cheese layering creates stringy melty bites throughout every serving
- Cover and Bake:
- Cover the baking dish tightly with aluminum foil to trap steam. Place in oven and bake covered for thirty five minutes. Check at this point to confirm the rice is nearly cooked and the casserole is bubbling gently at the edges
- Finish with Topping:
- Remove foil. Sprinkle remaining half cup of cheddar across the top. In a small bowl stir panko breadcrumbs with melted butter until well coated. Scatter breadcrumb mixture over casserole and bake uncovered ten more minutes. The topping should turn golden and the edges gently crisp
- Rest and Serve:
- When bubbling and golden remove casserole from the oven and let rest uncovered for five minutes to set. Sprinkle with chopped parsley just before serving for a pop of color and fresh flavor

Sharp cheddar is the real hero for me. The way it melts into every nook of rice and chicken feels like the heart of this casserole. My favorite memory is the winter when my whole family warmed up around the table after a snowball fight each of us with second helpings and even the vegetables disappeared without complaint.
Storage Tips
Leftovers store well for up to three days in the fridge in an airtight container. For best texture reheat covered in the oven at three hundred fifty degrees until hot. You can also portion it into individual containers for a ready lunch
Ingredient Substitutions
Use turkey or rotisserie chicken instead of raw chicken thighs just reduce the baking time since cooked protein needs less oven time. Swap the vegetables for whatever is in your freezer broccoli or green beans work well. If you do not have cheddar try Monterey Jack or a mix of what is on hand
Serving Suggestions
Pair with a green salad or simple steamed broccoli for a lighter meal. My family loves it with apple slices for a sweet counterbalance. Garlic bread or fresh biscuits are also perfect for soaking up every bit of the creamy sauce

With just one pan and a few honest ingredients you get a dinner that feels like a hug at the end of a long day. Try adding your own spin the next time you make it and pass along the tradition of comfort food that brings everyone together
