Ingredients
This recipe comes together with simple, accessible ingredients that you may already have in your pantry. The key is using the right type of rice and building layers of flavor from the start .
For the Casserole Base:
- 1.5 lbs (700g) boneless, skinless chicken thighs or breasts
- 1½ cups long-grain white rice (rinsed and drained)
- 3 cups low-sodium chicken broth
- ½ cup milk or half-and-half (for creaminess)
- 1 medium onion, finely diced
For the Garlic Butter Flavor Base:
- 6 tbsp unsalted butter
- 6 cloves garlic, minced (about 2 tbsp)
- 1 tsp Italian seasoning
- 1 tsp paprika (smoked paprika works too)
- 1½ tsp salt (start with 1 tsp if your broth is salty)
- ½ tsp black pepper
- ¼ cup grated Parmesan cheese (for a golden, cheesy finish)
Optional Add-Ins (Highly Recommended):
Important: Use regular long-grain white rice (like jasmine or basmati), not instant rice. Instant rice cooks too fast and can turn mushy in casseroles .

Step-by-Step Instructions
Follow these simple steps to create a hearty, flavorful one-pan meal that will quickly become a family favorite.
Step 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 .
Step 2: Season and Sear the Chicken
Pat the chicken pieces completely dry with paper towels—this is essential for a good sear . Season generously with salt, pepper, and paprika .
In a large oven-safe skillet or Dutch oven over medium-high heat, melt 2 tablespoons of butter . Sear the chicken for 5-6 minutes on the first side, until golden brown, then flip and sear for 3-4 minutes more . The chicken doesn’t need to be cooked through at this point—it will finish in the oven. Remove the chicken to a plate and set aside .
Pro Tip: The browned bits left in the pan (called “fond”) are pure flavor. Don’t wash the pan!
Step 3: Build the Garlic Butter Base
In the same skillet over medium heat, melt the remaining 4 tablespoons of butter . Add the diced onion and cook for 5-6 minutes until it starts to soften . Add the minced garlic and cook for 30 seconds to 1 minute until fragrant—be careful not to burn it .
Step 4: Toast the Rice
Add the uncooked rice to the skillet and stir for about 1 minute until the grains are coated in the garlic butter and start to look slightly translucent around the edges . This toasting step is the secret—it gives the rice an incredible nutty flavor and helps it stay fluffy rather than mushy .
Step 5: Add Liquids and Seasonings
Pour in the chicken broth and milk (or half-and-half), scraping up any browned bits from the bottom of the pan . Add the Italian seasoning, remaining salt, and pepper. Bring to a gentle boil, then reduce heat and simmer for about 2 minutes .
Step 6: Assemble and Bake
Nestle the seared chicken pieces on top of the rice mixture, skin-side up (if using thighs) . Pour any accumulated chicken juices from the plate over the top. Cover the dish tightly with foil .
Bake for 30 minutes with the foil on . Then, carefully remove the foil and bake for an additional 10-15 minutes uncovered, until the chicken reaches an internal temperature of 165°F (74°C) and the rice is tender .
Pro Tip: If you’re using bone-in, skin-on chicken thighs, the skin will become beautifully crispy during the final uncovered bake .
Step 7: Add the Finishing Touches
Remove from the oven and let the casserole rest for 5-10 minutes . This crucial step allows the rice to absorb any remaining liquid and prevents a mushy texture.
Sprinkle the Parmesan cheese over the top, scatter fresh parsley, and stir in the frozen peas if using the residual heat will warm them through without overcooking . Serve directly from the skillet or dish.

5 Essential Tips for the Best Garlic Butter Chicken & Rice Casserole
1. Choose the Right Rice
Long-grain white rice (jasmine or basmati) is the best choice. It holds its shape and absorbs flavors beautifully without becoming mushy . Avoid instant rice it’s too fast-cooking for this method .
2. Don’t Skip the Sear
Browning the chicken first isn’t just about color; it creates a flavor-packed fond at the bottom of the pan that infuses the entire casserole .
3. Let It Rest
The 5-10 minute rest after baking is non-negotiable. It allows the rice to set and the juices to redistribute, ensuring perfect texture and flavor .
4. Use Fresh Garlic
Freshly minced garlic provides the best flavor for the butter base. The jarred stuff just won’t deliver the same punch .
5. Adjust the Liquid for Brown Rice
If you want to use brown rice, increase the liquid slightly and extend the baking time by 15-20 minutes .
Delicious Variations to Explore
- Make It Cheesy: Stir shredded cheddar or mozzarella into the rice before baking, or sprinkle extra Parmesan on top .
- Add Veggies: Bulk up the dish with sliced mushrooms, frozen peas and carrots, or fresh spinach .
- Try Chicken Thighs: For an even juicier result, use boneless, skinless chicken thighs .
- Creamy Casserole: For a richer version, stir in a splash of heavy cream or a dollop of sour cream just before baking .
Storage and Reheating Guide
- Refrigeration: Store leftovers in an airtight container in the refrigerator for up to 4 days .
- Reheating: Reheat gently in a 350°F oven with a splash of broth to restore moisture, or microwave individual portions until hot .
Frequently Asked Questions (FAQ)
Q: Why did my rice turn out mushy?
A: This is often caused by using too much liquid, choosing the wrong rice (like short-grain or instant), or not letting the casserole rest before serving .
Q: Can I make this casserole ahead of time?
A: Yes! Assemble the casserole (before baking), cover, and refrigerate for up to 24 hours. Let it come to room temperature for about 30 minutes before baking. You may need to add 10-15 minutes to the baking time.
Q: Can I use rotisserie chicken instead?
A: Absolutely! Stir shredded rotisserie chicken into the rice mixture before baking, then bake the casserole just until heated through and the cheese is melted .
Q: What’s the secret to crispy chicken skin?
A: Pat the chicken completely dry before searing, and make sure the skillet is hot enough. The final uncovered bake also helps crisp the skin .
