Ingredients

2 boneless, skinless chicken breasts (about 1.5 lbs total)
1 tablespoon olive oil
1 teaspoon garlic powder
1 teaspoon onion powder
1/2 teaspoon dried oregano
1/4 teaspoon salt
1/4 teaspoon black pepper
1 tablespoon butter
1 cup long-grain white rice, uncooked
2 cups chicken broth
4 tablespoons butter
2 cloves garlic, minced
2 cups heavy cream
1/2 cup grated Parmesan cheese, plus more for topping
1/4 teaspoon salt
1/4 teaspoon black pepper
1/4 teaspoon nutmeg (optional, but highly recommended!)
1 cup frozen peas, thawed
1/2 cup shredded mozzarella cheese
Fresh parsley, chopped (for garnish)

Instructions

Step 1: Preheat oven to 375°F (190°C). Cut chicken breasts into bite-sized pieces if preferred.
Step 2: In a medium bowl, toss chicken with olive oil, garlic powder, onion powder, oregano, salt, and pepper.
Step 3: Place seasoned chicken in a baking dish.
Step 4: Bake for 20-25 minutes, or until cooked through and internal temperature reaches 165°F (74°C). Shred or dice if baked whole.
Step 5: In a medium saucepan, melt 1 tablespoon butter over medium heat.
Step 6: Add uncooked rice and cook for 1-2 minutes, stirring constantly.
Step 7: Pour in chicken broth and bring to a boil. Reduce heat to low, cover, and simmer for 18-20 minutes, or until rice is cooked and liquid is absorbed.
Step 8: Fluff rice with a fork and set aside.
Step 9: In a large saucepan, melt 4 tablespoons butter over medium heat.
Step 10: Add minced garlic and cook for 1 minute, or until fragrant.
Step 11: Pour in heavy cream and bring to a simmer. Reduce heat to low and simmer for 5-7 minutes, until sauce thickens slightly.
Step 12: Stir in Parmesan cheese, salt, pepper, and nutmeg if using. Simmer for another 2-3 minutes until cheese melts and sauce is smooth.
Step 13: Taste and adjust seasonings as needed.
Step 14: Preheat oven to 350°F (175°C).
Step 15: In a large bowl, combine cooked chicken, rice, Alfredo sauce, and thawed peas.
Step 16: Pour mixture into a greased 9×13 inch baking dish.
Step 17: Sprinkle shredded mozzarella cheese evenly over the top.
Step 18: Bake for 20-25 minutes, until cheese is melted, bubbly, and casserole is heated through.
Step 19: Remove from oven and let cool for a few minutes before serving.
Step 20: Garnish with chopped fresh parsley.

Tips & Variations

For extra flavor, use homemade chicken broth or add sautéed mushrooms to the casserole.
Swap peas for other vegetables like broccoli or spinach for variation.
Use leftover cooked chicken to save time.
Add a pinch of red pepper flakes to the Alfredo sauce for a mild kick.

Storage

Store leftover casserole in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350°F (175°C) until warmed through, or microwave individual portions until hot.
