French Onion Soup (canned or homemade): The secret ingredient that brings bold, caramelized onion flavor in every bite.

Shredded Cheese (Swiss, Gruyère, or Mozzarella): Melty and gooey, it ties everything together like a warm hug.

Butter or Olive Oil: To sauté any added veggies or grease your baking dish.

Instructions

Let’s dive into the steps to create this flavorful masterpiece:

Preheat Your Equipment: Preheat your oven to 350°F (175°C). A warm oven means even cooking and that golden, bubbly finish.

Cook the Chicken (if needed): If using raw chicken, dice and quickly sauté until lightly browned but not fully cooked it’ll finish in the oven.

Mix the Base: In a large bowl, combine cooked rice, French onion soup, sour cream (or cream of chicken soup), and half of the shredded cheese. Stir until everything is coated and creamy.

Add the Chicken: Fold in the chicken pieces, making sure they’re evenly distributed throughout the mixture.

Prepare Your Baking Dish: Grease your casserole dish to prevent sticking and make cleanup a breeze.

Assemble the Dish: Pour the rice and chicken mixture into the dish and spread evenly. Sprinkle the remaining cheese on top, followed by a generous layer of crispy fried onions.

Bake to Perfection: Cover with foil and bake for 25 minutes. Remove foil and bake for another 10–15 minutes, or until bubbly and golden on top.

Let It Rest: Remove from the oven and let it sit for 5 minutes before serving. This helps the flavors settle and the texture firm up a bit.

Serve and Enjoy: Scoop it up and dig into a bowl of warm, savory comfort.
