Ingredients of the Chicken and Rice Casserole
For the Main Casserole
- 1.5 lbs boneless skinless chicken breasts, cut into 1-inch cubes
- 1.5 cups long-grain white rice, rinsed
- 3 cups high-quality chicken broth
- 1 cup frozen peas and carrots
- 1 small yellow onion, finely diced
- 2 cloves garlic, minced
- 1 tsp dried thyme
- 1 tsp onion powder
- Salt and black pepper to taste
For the Creamy Base
- 1 cup sour cream or full-fat Greek yogurt
- 1/2 cup shredded cheddar cheese
- 2 tbsp olive oil

Equipment / Tools Needed
- Large oven-safe skillet or deep baking dish
- Heavy-duty aluminum foil
- Chef’s knife and cutting board
- Mixing bowl
- Measuring cups and spoons
Step-by-Step Instructions
Step 1: Prepare the Oven and Ingredients
Preheat your oven to 375°F (190°C). Prepare your chicken by trimming any excess fat and cutting it into uniform cubes to ensure even cooking. Rinse the rice thoroughly under cold water until the water runs clear, which helps remove excess starch for a fluffier result.
Step 2: Sauté the Aromatics and Chicken
In your oven-safe skillet or a large pan, heat the olive oil over medium-high heat. Add the diced onion and sauté until translucent. Add the chicken pieces, seasoning generously with salt, pepper, thyme, and onion powder. Cook just until the chicken is lightly browned on the outside—it does not need to be cooked through at this stage.
Step 3: Combine the Base
Stir the rinsed rice, minced garlic, and chicken broth into the skillet with the chicken. Scrape the bottom of the pan to release any browned bits, as these provide a concentrated boost of flavor. Bring the liquid to a gentle simmer on the stovetop for two minutes.
Step 4: Bake to Perfection
Remove from heat and stir in the frozen vegetables and the sour cream or Greek yogurt. Cover the dish tightly with aluminum foil to trap the steam. Place it in the oven and bake for 35 to 40 minutes, or until the rice is tender and the liquid is absorbed.
Step 5: Finish and Serve
Remove the foil, sprinkle the shredded cheddar cheese over the top, and place back in the oven for 5 minutes or until the cheese is bubbling and slightly golden. Let it rest for 10 minutes before serving to allow the textures to set.

Tips & Tricks
For the best texture, always ensure your rice is well-rinsed; this prevents the casserole from becoming gummy. If you prefer a more golden crust, leave the foil off for the final 5 minutes of baking. For extra depth, use fresh herbs like parsley or chives as a garnish right before bringing the dish to the table.
Serving Suggestions
This casserole pairs beautifully with a crisp green side salad tossed in a lemon vinaigrette to cut through the richness of the creamy rice. In colder months, serve it alongside roasted broccoli or steamed green beans. It is a hearty main dish that serves well for casual Sunday family dinners or meal-prepped lunches throughout the week.
Variations / Substitutions
- Swap the chicken breast for chicken thighs if you prefer darker, juicier meat.
- Use brown rice for a nuttier flavor profile, but note that it requires an extra half-cup of broth and a longer baking time.
- Add sautéed mushrooms or bell peppers for extra texture and nutritional variety.
- For a dairy-free approach, substitute the sour cream with a high-quality coconut milk or unsweetened almond-based cream alternative.
Storage and Reheating
Store leftovers in an airtight container in the refrigerator for up to 3 days. When reheating, add a small splash of water or broth to the dish to rehydrate the rice. Heat in the oven at 350°F covered, or use the microwave in short intervals, stirring occasionally to ensure even heating.

FAQ
Can I prepare this casserole ahead of time?
Yes, you can assemble the ingredients earlier in the day and keep them in the refrigerator. However, for the best texture, wait to add the rice and broth until just before you are ready to bake, or the rice may absorb too much liquid and become soft.
Is it possible to use brown rice in this recipe?
Absolutely, though you must increase the chicken broth by about 1/2 cup and increase the baking time by approximately 15 to 20 minutes. Ensure the dish is tightly covered so the brown rice has enough moisture to steam properly.
What if my rice comes out too dry?
If your rice is still crunchy after the recommended baking time, add a splash of warm broth, stir gently, cover, and bake for another 5 to 10 minutes. The resting period is crucial, as it allows the final bit of moisture to distribute evenly through the rice grains.
Can I freeze the leftovers?
This dish freezes reasonably well in individual portions. Place it in a freezer-safe container and consume within one month for the best quality. Thaw in the refrigerator overnight and reheat with a splash of broth to revive the creamy texture.
