Garlic Butter Chicken and Rice Casserole (Easy One-Pan Meal)
Comforting one-pan garlic butter chicken and rice casserole with tender chicken, fluffy rice, and vegetables. Perfect for busy weeknight dinners.

The Art of One-Pan Cooking
Successful one-pan meals rely on layering flavors and understanding how different ingredients cook together. The key to this casserole is browning the chicken first to create a flavorful fond, then using that same pan to build the garlic butter base that will infuse the entire dish.
Rice selection matters greatly in casseroles. Long-grain white rice holds its shape and absorbs flavors beautifully without becoming mushy. The unrinsed rice helps thicken the cooking liquid slightly, creating a creamy texture that binds everything together perfectly.
💡 Professional Tip
Don't rinse the rice before cooking - the natural starch helps create a creamier texture and prevents the casserole from being too loose. The chicken skin should be crispy when it goes into the oven for the best final texture.
Frequently Asked Questions
Yes, use boneless thighs or breasts, but reduce the initial browning time to 3-4 minutes per side and check for doneness after 25 minutes of baking since they cook faster.
Simply replace the wine with additional chicken broth. You can also use a splash of white wine vinegar or lemon juice for acidity if desired.
You can prep the vegetables and season the chicken ahead, but it's best to cook the casserole fresh. The rice can become mushy if assembled too far in advance.
The rice should be tender when pierced with a fork and have absorbed most of the liquid. If there's still excess liquid, bake uncovered for an additional 5-10 minutes.
Brown rice needs more liquid and longer cooking time. Use 4 cups of broth instead of 3, and increase the covered baking time to 45 minutes before removing the foil.
Bell peppers, green beans, or broccoli work well. Add heartier vegetables with the onions, and tender ones like peas or broccoli in the last 10 minutes of cooking.
Make sure your pan is well-buttered and the liquid comes to a proper simmer before covering. Avoid stirring the rice once it's in the oven to prevent sticking.
Store covered in the refrigerator for up to 3 days. Reheat in the oven at 350°F with a splash of broth to restore moisture, or microwave individual portions.
Recipe Troubleshooting Guide
Dry Rice
Problem: Rice turns out dry or undercooked
Solution: Add more hot broth (1/2 cup at a time) and continue baking covered. Make sure the casserole is tightly covered with foil during cooking.
Soggy Rice
Problem: Rice becomes mushy or too wet
Solution: Remove foil and bake additional 10-15 minutes to evaporate excess liquid. Use less broth next time or ensure proper simmering before baking.
Burnt Bottom
Problem: Bottom of casserole burns while rice is still undercooked
Prevention: Lower oven temperature to 350°F and cover tightly. The pan may have been too hot initially, so let it cool slightly before baking.
Pale Chicken Skin
Problem: Chicken skin doesn't brown properly
Recovery: Increase oven temperature to 400°F for the last 10 minutes, or broil for 2-3 minutes. Make sure chicken skin is dry before initial browning.
Bland Flavor
Problem: Casserole lacks flavor depth
Prevention: Season chicken more generously, use quality chicken broth, and don't skip the wine. Finish with extra garlic butter and fresh herbs.
Flavor Balance Issues
Too Sweet: Add a squeeze of lemon juice or a splash of vinegar
Too Salty: Serve with a dollop of sour cream or plain yogurt
Bland: Increase garlic, add fresh herbs, or finish with lemon zest and black pepper

Choosing the Right Ingredients
Bone-in, skin-on chicken thighs are the star of this dish, providing superior flavor and staying moist during the longer cooking time. The bones add richness to the cooking liquid while the skin crisps beautifully when properly browned initially.
Quality chicken broth makes a significant difference in the final flavor. Look for low-sodium options so you can control the salt level, and consider using homemade broth if available. The broth becomes the cooking liquid for the rice, so its flavor permeates the entire dish.
Essential Ingredient Notes
- Chicken Selection: Choose thighs of similar size for even cooking. Pat skin completely dry before browning for the crispiest results.
- Rice Quality: Use long-grain white rice like basmati or jasmine for the best texture. Avoid instant or pre-cooked rice which will become mushy.
- Fresh Garlic: Fresh garlic provides the best flavor for the butter base. Mince it finely so it distributes evenly and doesn't burn during cooking.

Mastering the One-Pan Technique
The secret to exceptional one-pan cooking lies in building layers of flavor sequentially. Start by browning the chicken to create fond, then use that same flavorful base to cook the aromatics and toast the rice, ensuring every grain is infused with rich taste.
Temperature control is crucial for perfect results. The initial browning requires medium-high heat, while the oven cooking should be gentle enough to cook the rice evenly without drying out the chicken. Covering tightly traps steam for perfectly tender rice.
The Perfect Simmer
Before transferring to the oven, ensure the liquid reaches a gentle simmer. This head start helps the rice cook evenly and prevents the bottom from burning while the top remains undercooked.

Instructions
Prepare Chicken
Preheat oven to 375°F (190°C). Season chicken thighs with salt, pepper, and paprika. Heat olive oil in a large oven-safe skillet or Dutch oven over medium-high heat. Brown chicken skin-side down for 5-6 minutes, then flip and brown 3-4 minutes more. Remove and set aside.

In the same pan, melt 4 tablespoons butter over medium heat. Add minced garlic and cook for 30 seconds until fragrant. Add onion, carrots, and celery. Cook for 5-6 minutes until vegetables start to soften.
Add Rice and Liquids
Stir in rice, coating with the garlic butter mixture. Add chicken broth, wine, thyme, and rosemary. Bring to a gentle boil, then reduce heat and simmer for 2 minutes.
Assemble and Bake
Nestle browned chicken thighs on top of rice mixture, skin-side up. Cover tightly with foil and bake for 30 minutes. Remove foil and bake additional 10-15 minutes until chicken reaches 165°F (74°C) and rice is tender.
