Recipe for Chicken Breast and Rice Casserole: Creamy One-Dish Comfort Meal

This one-dish wonder transforms simple ingredients into a creamy, satisfying meal that feels like home. I developed this casserole for busy weeknights when comfort food is needed without the fuss.

The secret lies in baking the chicken and rice together, allowing the flavors to meld into a rich, velvety sauce. No pre-cooking required—just assemble and let the oven do the work.

What emerges is tender chicken breast nestled in perfectly cooked rice, all enveloped in a creamy sauce that’s both hearty and light. It’s the kind of dish that warms you from the inside out.

Ideal for family dinners or meal prep, this casserole delivers on both taste and convenience. Here’s how to make it.

Pantry staples plus a few fresh items. Everything comes together in one dish.

The chicken is the foundation here—Costco has great prices on boneless breasts in bulk. For the rice, long-grain white absorbs the creamy sauce best (jasmine or basmati work too, but they can get mushy). The cream of chicken soup is non-negotiable for that velvety texture, and Campbell’s is the most reliable brand. Sour cream adds tang, so don’t skip it—full-fat Daisy is my go-to.

No cream of chicken soup? Cream of mushroom works in a pinch (just add a dash of poultry seasoning). Out of cheddar? Monterey Jack melts beautifully. Want to lighten it up? Swap sour cream for Greek yogurt—same tang, less guilt. The peas are optional but add a nice pop of color (frozen is fine, no need to thaw). If you’re using fresh thyme, triple the amount since it’s less concentrated.

Assemble it in the morning, refrigerate, then bake when you get home. Leftovers keep 4-5 days in the fridge (the rice soaks up more sauce overnight). Freeze portions for up to 3 months—just thaw in the fridge before reheating.

Step-by-Step Instructions for Chicken Breast and Rice Casserole

This one-dish wonder comes together easily with a few simple layers and a hot oven.

Step 1: Prep the Chicken and Aromatics

Cut the 1.5 lb boneless skinless chicken breast into bite-sized pieces—this ensures quick, even cooking. I keep them uniform so every bite has the same tender texture. Finely dice the yellow onion and mince the 3 cloves garlic cloves; you want small pieces that melt into the sauce.

This prep work is your foundation. The chicken cooks directly in the casserole, so cutting it small prevents dry, overcooked pieces. The onion and garlic will soften into the creamy sauce, adding depth without overpowering.

Step 2: Build the Rice and Sauce Base

In a large bowl, combine the 1.5 cups long-grain white rice, 2 cans cream of chicken soup, 2.5 cups chicken broth, 1 cup sour cream, 0.25 cup butter, 0.25 cup all-purpose flour, 1 tsp salt, 0.5 tsp black pepper, and 0.5 tsp dried thyme. Stir until everything is fully incorporated and the rice is evenly coated.

The flour thickens the sauce as it bakes, while the broth and soup provide moisture for the rice to absorb. I always use low-sodium broth here so I can control the seasoning.

Step 3: Layer Everything in the Baking Dish

Spread the rice mixture evenly in a greased 9×13-inch baking dish. Distribute the chicken pieces and diced yellow onion evenly over the top, then sprinkle the 3 cloves garlic cloves across. Press everything down gently so the chicken sinks slightly into the rice.

This layering ensures the chicken cooks in the steam from the rice, keeping it juicy. The onion and garlic infuse flavor throughout as everything bakes together.

Step 4: Bake Until Bubbly and Golden

Cover the dish tightly with foil and bake at 375°F for 45 minutes. Then, remove the foil, sprinkle the 2 cups shredded cheddar cheese evenly over the top, and scatter the 1 cup frozen peas across the surface. Return to the oven uncovered for another 15-20 minutes until the cheese is melted and golden and the casserole is bubbling at the edges.

The peas add a pop of color and sweetness, and they cook perfectly in this final stretch. You’ll know it’s done when the cheese is fully melted and the edges are bubbly and lightly browned.

Step 5: Rest and Serve

Let the casserole rest for 10 minutes after removing it from the oven. This allows the sauce to thicken and the flavors to meld together. The rice will finish absorbing any remaining liquid, and the cheese will set slightly for cleaner serving.

Scoop generous portions into bowls—the creamy sauce, tender chicken, and fluffy rice should come together in every bite. This dish is comfort in its purest form, and it only gets better as it sits.

Essential Equipment for Perfect Results

Baking Dish Essentials

For this casserole, a 9×13-inch baking dish is non-negotiable. I use my vintage Pyrex—it distributes heat evenly and the glass lets me monitor the rice cooking. A 3-quart capacity gives the rice room to expand without overflowing. 💡

Mixing Bowl Matters

A large mixing bowl (I prefer stainless steel) makes combining the rice and sauce base effortless. Look for one with a 4-6 quart capacity to accommodate all ingredients without spills. My All-Clad bowl has lasted me over a decade of heavy use.

Cutting Tools

A sharp 8-inch chef’s knife makes quick work of the chicken and onions. I use my Wüsthof for precise, uniform pieces. Pair it with a cutting board that has a juice groove—chicken releases liquid as you cut.

Measurement Accuracy

For consistent results, use nested measuring cups and measuring spoons. I keep a OXO set in my drawer—the magnetic handles stay organized. The ¼ cup and ½ tsp get heavy use in this recipe. ✨

Cheese Grater

While pre-shredded cheddar works, freshly grated melts better. I use a box grater for the 2 cups cheddar—the large holes create perfect meltable shreds. Clean it immediately after use to prevent cheese from hardening.

Aluminum Foil

Heavy-duty aluminum foil is crucial for that initial 45-minute covered bake. The heavy weight prevents tearing when removing it. I always keep a Reynolds Wrap roll in my pantry for casseroles like this. 🔥
