Ingredients
For the Casserole:
- 6 boneless, skinless chicken thighs (or 4 large chicken breasts)
- 1½ cups long-grain white rice (uncooked)
- 3 cups chicken broth (low-sodium recommended)
- 6 tablespoons unsalted butter, melted
- 6 cloves garlic, minced
- 1 teaspoon onion powder
- 1 teaspoon salt
- ½ teaspoon black pepper
- ½ teaspoon paprika
- 1 tablespoon fresh parsley, chopped (or 1 teaspoon dried)
For the Topping:
- ½ cup grated Parmesan cheese
- ¼ cup shredded mozzarella cheese (optional, for extra gooeyness)
For Garnish:
- Additional fresh parsley, chopped

Ingredient Notes
Chicken: Chicken thighs are my top choice for this recipe because they stay moist and juicy during baking. If you prefer white meat, boneless, skinless chicken breasts work well too just keep an eye on them to avoid drying out.
Rice: Long-grain white rice is essential here. It absorbs the broth and butter beautifully, resulting in fluffy, separate grains. Avoid using instant or quick-cooking rice, as they’ll become mushy. Brown rice can be used but requires more liquid and a longer baking time.
Garlic: Fresh garlic is non-negotiable for the best flavor. Pre-minced jarred garlic simply doesn’t deliver the same punch. Adjust the amount to your taste I use six cloves for a robust garlic flavor.
Chicken Broth: Low-sodium broth gives you more control over the saltiness of the final dish. If you only have regular broth, reduce the added salt accordingly.
Cheese: Parmesan adds a lovely salty, nutty flavor, while mozzarella provides that beautiful stretchy, gooey topping. You can use one or both, or skip the cheese entirely for a lighter version.

Step-by-Step Instructions
1. Preheat and Prepare
Preheat your oven to 375°F (190°C) . Lightly grease a 9×13-inch baking dish with cooking spray or a bit of butter.
2. Make the Garlic Butter Mixture
In a medium bowl, whisk together the melted butter, minced garlic, chicken broth, onion powder, salt, pepper, and paprika. This flavorful base will cook the rice to perfection.
3. Assemble the Base Layer
Pour the uncooked rice into the prepared baking dish and spread it out in an even layer. Carefully pour the garlic butter broth mixture over the rice, making sure all the grains are submerged. This ensures the rice cooks evenly.
4. Add the Chicken
Season the chicken thighs or breasts with additional salt, pepper, and paprika if desired. Nestle the seasoned chicken pieces directly on top of the rice. The chicken will release juices as it bakes, adding even more flavor to the rice below.
5. Cover and Bake
Cover the baking dish tightly with aluminum foil. This traps the steam, which is essential for cooking the rice properly. Bake for 35 minutes at 375°F.
6. Uncover and Finish
Carefully remove the foil. If you’re using cheese, sprinkle the Parmesan and mozzarella evenly over the top of the chicken and rice. Return the uncovered dish to the oven and bake for another 10-15 minutes, until the chicken is cooked through (internal temperature reaches 165°F) and the rice is tender and fluffy.
7. Rest and Serve
Remove the casserole from the oven and let it rest for 5-10 minutes before serving. This allows the rice to firm up slightly, making it easier to serve. Garnish with fresh parsley before serving.
Expert Tips
- Use a Heavy-Duty Baking Dish: A glass or ceramic 9×13-inch dish works best for even heat distribution. Avoid thin metal pans that can cause hot spots.
- Don’t Peek: Resist the urge to lift the foil during the first 35 minutes of baking. The steam is crucial for cooking the rice properly.
- Check the Rice: If the rice isn’t fully cooked after the initial 35 minutes, add a splash of hot broth or water, cover, and bake for another 5-10 minutes.
- Let It Rest: The 5-10 minute rest after baking is non-negotiable. It allows the rice to set and the juices to redistribute, making the final dish even more delicious and easier to serve.
- Add Vegetables: To make this a complete one-pan dinner, stir in a cup of frozen peas, diced carrots, or chopped spinach before adding the chicken. They’ll cook perfectly alongside the rice.
Variations
- Creamy Version: For an extra rich and creamy casserole, stir ½ cup of heavy cream or cream cheese into the broth mixture before pouring over the rice.
- Spicy Kick: Add ½ teaspoon of red pepper flakes to the garlic butter mixture for a touch of heat.
- Herb-Infused: Stir in 1 teaspoon of dried thyme or rosemary along with the other seasonings for an herby twist.
- Cheesy Chicken & Rice: Double the cheese topping and add an extra ½ cup of shredded cheddar for a cheesier finish.
- Use Brown Rice: You can use brown rice, but be prepared to increase the liquid to 3½ cups and extend the baking time to 1 hour.
Storage Instructions
Store leftovers in an airtight container in the refrigerator for up to 4 days. The flavors often meld and taste even better the next day.
For longer storage, you can freeze the casserole for up to 2 months. Thaw overnight in the refrigerator before reheating.
Reheating Tips
- Oven: Reheat in a 350°F oven for 15-20 minutes, covered, until warmed through.
- Microwave: Reheat individual portions in the microwave on medium power for 2-3 minutes.
- Stovetop: Reheat in a skillet over medium heat with a splash of broth to loosen the rice.
Common Mistakes to Avoid
- Using the Wrong Rice: Instant or quick-cooking rice will turn mushy. Always use long-grain white rice for the best texture.
- Skipping the Foil: Covering the dish during the first half of baking is essential. Without it, the rice won’t cook properly.
- Overcooking the Chicken: Chicken breasts can dry out quickly. Use thighs for the juiciest results, or monitor breasts closely.
- Adding Too Much Liquid: Stick to the recommended 2:1 liquid-to-rice ratio. Too much liquid will result in soggy rice.
- Forgetting to Season: Don’t skimp on salt and spices they’re what make this dish so flavorful.
What to Serve With
- Green Vegetables: Serve with steamed broccoli, green beans, or a simple side salad for a complete meal.
- Crusty Bread: A slice of warm, crusty bread is perfect for soaking up any extra garlic butter sauce.
- Roasted Vegetables: Roasted asparagus, Brussels sprouts, or carrots pair beautifully with this rich casserole.
- A Glass of Wine: A crisp white wine like Sauvignon Blanc or a light Chardonnay complements the garlic butter flavors perfectly.
Frequently Asked Questions
Q: Can I use boneless, skinless chicken breasts instead of thighs?
A: Yes, but keep a close eye on them to prevent drying out. Chicken breasts typically take about 25-30 minutes to cook, so check the temperature early.
Q: Can I make this casserole ahead of time?
A: Absolutely! Assemble the entire casserole (before baking) and refrigerate for up to 24 hours. When you’re ready to cook, let it sit at room temperature for 30 minutes, then bake as directed. You may need to add 10-15 minutes to the baking time.
Q: Why is my rice still crunchy?
A: This usually means the liquid ratio was off or the dish wasn’t covered tightly enough. Make sure you’re using the correct amount of broth and that the foil is sealed tightly around the edges.
Q: Can I use a different type of rice?
A: Long-grain white rice works best. Brown rice requires more liquid and a longer baking time, while instant rice will become mushy.
Q: How do I store leftovers?
A: Store in an airtight container in the refrigerator for up to 4 days. Reheat in the oven or microwave.
Q: Can I freeze this casserole?
A: Yes! Freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.
Q: What can I add to make it more flavorful?
A: Try adding sautéed mushrooms, onions, or bell peppers to the rice layer. You can also experiment with different herbs like thyme or rosemary.
