French Onion Chicken Rice Casserole Ingredients

For the Casserole
• Chicken Breasts or Thighs – Provides tender, juicy protein that absorbs the casserole’s rich flavors; rotisserie or canned chicken can also be used for convenience.
• Cooked Rice – Acts as the base; either white or brown rice can be utilized, but ensure it’s pre-cooked. Brown rice can enhance the dish’s nutty flavor.
• French Onion Soup – This key ingredient infuses bold, caramelized onion flavor throughout the casserole; consider homemade for an extra depth of taste.
• Sour Cream or Cream of Chicken Soup – Adds creaminess with a tangy twist to balance the dish’s richness; Greek yogurt is a lighter substitute.
• Shredded Cheese (Swiss, Gruyère, or Mozzarella) – Offers melty richness that ties all the flavors together; Gruyère adds a classic French flavor, while cheddar is a widely-used alternative.
• Crispy Fried Onions – Provides a delightful crunch on top of the casserole; seasoned breadcrumbs can be used as a substitute if needed.
• Butter or Olive Oil – Used for greasing the baking dish; olive oil is a healthier fat option if you’re watching your intake.
• Salt and Pepper – Essential for seasoning; adjust according to your personal taste.

Step‑by‑Step Instructions for French Onion Chicken Rice Casserole

Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). This ensures the French Onion Chicken Rice Casserole bakes evenly, allowing the flavors to meld beautifully. While the oven warms up, take out a medium-sized baking dish and lightly grease it with butter or olive oil to prevent sticking and enhance the dish’s flavor.

Step 2: Prepare the Chicken
If you’re using raw chicken, dice the chicken breasts or thighs into bite-sized pieces. In a large skillet over medium heat, add a teaspoon of olive oil, then sauté the chicken for about 5–7 minutes until it’s lightly browned but not fully cooked. This step allows the chicken to absorb the rich flavors of the casserole later on.

Step 3: Mix the Base
In a large mixing bowl, combine the cooked rice, French onion soup, and sour cream (or cream of chicken soup). Stir in half of the shredded cheese, mixing thoroughly to create a creamy, flavorful base for your casserole. This combination exudes the comforting essence that makes the French Onion Chicken Rice Casserole so irresistible.

Step 4: Incorporate the Chicken
Gently fold the sautéed chicken into the rice mixture, ensuring it’s evenly distributed throughout. This step is crucial, as it ensures every bite of the casserole is filled with tender chicken. Make sure the chicken is well coated with the creamy mixture, blending the flavors beautifully.

Step 5: Assemble the Casserole
Pour the chicken and rice mixture into the greased baking dish, spreading it out evenly with a spatula. Top the casserole with the remaining shredded cheese, creating a deliciously cheesy layer on top. Lastly, sprinkle crispy fried onions over the cheese for added texture and a delightful crunch, elevating your French Onion Chicken Rice Casserole.

Step 6: Bake the Casserole
Cover the baking dish with aluminum foil and place it in the preheated oven. Bake for 25 minutes to allow the flavors to meld together. After this initial baking time, remove the foil and bake for an additional 10–15 minutes, or until the top is bubbly and golden brown. This will give your casserole that desirable, inviting appearance.

Step 7: Rest & Serve
Once baked, remove the French Onion Chicken Rice Casserole from the oven and let it rest for about 5 minutes. This resting period allows the dish to set slightly, making it easier to serve. Use a scoop to dish out the casserole and enjoy this hearty, comforting meal with your family or guests!
