Why you’ll love this recipe

This Pesto Chicken and Rice Casserole balances rich Parmesan and cream with the herbaceous lift of pesto. Long grain white rice bakes tender without becoming mushy, and diced roma tomatoes add juicy brightness. The dish is layered with simple pantry ingredients—chicken stock, a little heavy cream, and Italian seasoning if you like a herby accent—so you can pull it together quickly. It’s also flexible: swap in thawed frozen peas for a green pop or sprinkle extra Parmesan at the end for a golden finish.

Ingredients

1 cup long grain white rice
1 cup Parmesan cheese, divided
6 tablespoons prepared pesto, divided
2 boneless skinless chicken breasts, about 1 lb.
salt & pepper to taste
2 1/4 cups chicken stock
2 roma tomatoes, diced
3 tablespoons heavy cream
Italian seasoning (optional)

Equipment

9×9-inch or similar baking dish
Medium saucepan or skillet (for browning chicken, optional)
Mixing bowl and measuring cups/spoons
Aluminum foil (optional)

Make-ahead and serving suggestions

You can assemble the casserole up to a day ahead, cover it, and refrigerate until ready to bake. Let it sit at room temperature for 20–30 minutes before baking so it bakes evenly. Serve the casserole with a simple green salad and crusty bread, or add a squeeze of lemon over each portion for extra brightness. Leftovers reheat beautifully in the oven at 350°F (175°C) covered with foil for 15–20 minutes or in the microwave for single servings.

Step-by-step instructions

The following directions are rewritten to be clear and easy to follow while keeping the ingredient amounts and order as provided. Read through once before you start so the process feels smooth.

Preheat and prepare: Preheat your oven to 375°F (190°C). Lightly grease a 9×9-inch baking dish or a similar-sized casserole pan. This helps prevent sticking and makes cleanup easier.
Season the chicken: Pat the 2 boneless skinless chicken breasts dry with paper towels. Season both sides of the chicken breasts with salt and pepper to taste. If you’d like a little extra herb flavor, sprinkle a light dusting of Italian seasoning over the chicken, but this is optional.
Optional — brown the chicken (for flavor and color): If you want a richer flavor and a nice golden color on the chicken, heat a tablespoon of oil in a skillet over medium-high heat. Add the seasoned chicken breasts and sear for 2–3 minutes per side until lightly browned. The chicken does not need to be fully cooked through in this step because it will finish baking in the casserole. Transfer the chicken to a cutting board and let it rest for a few minutes, then cut into bite-sized pieces or cubes.
Combine rice and liquids: Pour 1 cup of long grain white rice into the prepared baking dish. Add 2 1/4 cups of chicken stock to the rice. Stir gently to distribute the rice evenly in the dish so it sits in a single layer and can absorb the stock uniformly.
Add pesto and cream: Stir 3 tablespoons of the prepared pesto into the rice and chicken stock mixture. Then add 3 tablespoons of heavy cream and mix lightly to combine. These elements will infuse the rice with herb and cream flavors as it bakes.
Layer in chicken and tomatoes: Scatter the diced roma tomatoes evenly over the rice mixture. Arrange the cut chicken pieces across the top of the rice so they are spread out rather than piled in one spot. If you skipped searing, simply dice the raw seasoned chicken and nestle it into the rice and liquid now; it will cook fully during baking.
Top with cheese and remaining pesto: Sprinkle 3/4 cup of the Parmesan cheese across the casserole surface. Dollop the remaining 3 tablespoons of prepared pesto over the top in small spoonfuls, then gently swirl or leave as-is; either approach gives pockets of concentrated pesto flavor. If you prefer a more even pesto distribution, thin the remaining pesto with a teaspoon of water and drizzle lightly before baking.
Bake covered: Cover the baking dish tightly with aluminum foil or a well-fitting lid. Place it on the center rack of the preheated oven and bake for 30 minutes. Covering traps steam so the rice cooks through without drying out.
Uncover and finish baking: After 30 minutes, carefully remove the foil. Sprinkle the remaining 1/4 cup of Parmesan cheese across the casserole. Return the dish to the oven, uncovered, and bake for an additional 10–15 minutes. The top should be slightly golden and the rice tender; the internal temperature of the chicken should reach 165°F (74°C) if you test with a thermometer. If you like a more pronounced golden top, you can broil for 1–2 minutes at the end—watch closely so the cheese doesn’t burn.
Rest before serving: Remove the casserole from the oven and let it rest, uncovered, for 5–10 minutes. Resting helps the rice finish absorbing any residual liquid and makes the casserole easier to serve. Taste and adjust salt and pepper as needed.
Serve and garnish: Scoop portions onto plates and garnish with a sprinkle of extra Parmesan, a small spoonful of pesto, or freshly chopped basil if you have it. A light drizzle of extra virgin olive oil or a squeeze of lemon brightens the flavors beautifully.

Flavor tips and variations

Veggie boost: Stir in 1 cup of thawed frozen peas or a cup of chopped spinach during the last 10 minutes of baking for color and nutrition.
Cheese variations: Swap half of the Parmesan for mozzarella if you prefer a stretchy, melty topping. Keep the total cheese amount the same to maintain texture.
Spice it up: Add a pinch of red pepper flakes to the pesto before dolloping on top if you like a little heat.
Make it lighter: Use half-and-half instead of heavy cream for a lighter finish, or omit the cream entirely and add an extra 1/4 cup of chicken stock if you prefer less richness.

Troubleshooting

Rice is still firm after time is up: If the rice hasn’t absorbed the liquid fully, cover and bake an additional 5–10 minutes. If it seems dry but still undercooked, add 1/4 cup extra chicken stock and continue baking.
Top browns too quickly: If the top is getting too dark while the rice needs more time, loosely tent the dish with foil and continue baking until done.
Chicken cooks unevenly: Cutting the chicken into uniform pieces before placing it in the casserole helps ensure even cooking. If using thick breasts, sear or even halve them horizontally so they finish in sync with the rice.

Notes on ingredients

This recipe uses 1 cup of long grain white rice and 2 1/4 cups of chicken stock; that ratio produces tender grains that remain separate, not mushy. The Parmesan cheese is split so some melts into the rice while some creates a savory topping—keep the division as written for the intended texture. Six tablespoons of prepared pesto are divided so the herb flavor is both inside and on top of the casserole. Two boneless skinless chicken breasts (about 1 lb.) deliver protein without excess fat. Finish with 3 tablespoons of heavy cream for silkiness and two diced roma tomatoes for juiciness. Salt and pepper are to taste; add them before baking and adjust after tasting the finished dish.

Serving size and storage

This casserole serves about 4 people as a main dish. To store, cool the casserole to room temperature, cover tightly, and refrigerate for up to 3 days. Reheat single portions in the microwave or rewarm the entire dish in a 350°F (175°C) oven until heated through. For longer storage, portion into freezer-safe containers and freeze for up to 2 months; thaw overnight in the fridge before reheating.

Final thoughts

Pesto Chicken and Rice Casserole is a weeknight-friendly recipe that still feels made with care. It’s an easy one-pan (ish) meal that delivers a comforting, creamy base with vibrant pesto pockets and juicy tomato pops. The rewritten, step-by-step directions keep the original ingredient amounts intact while making the method easier to follow, so you can enjoy a reliably delicious result every time.

Happy cooking — and don’t forget to give the casserole a quick taste test for salt and pepper before you serve. Small adjustments at the end make all the difference.
