 Step-by-Step Instructions

Step 1: Preheat Oven & Prepare Dish

1. Preheat your oven to 350°F (175°C).

2. Spray a 9×13 inch casserole dish with non-stick spray.

Step 2: Mix the Casserole Base

In a large mixing bowl, stir together:

• Uncooked rice

• French onion soup

• Cream of chicken soup

• Chicken broth

• Sour cream (if using)

• Garlic powder, onion powder, and Worcestershire sauce (if using)

Pro Tip: If using rotisserie chicken, remove the skin and shred the meat for ultra-tender texture.

Step 3: Assemble the Casserole

1. Pour the mixture into your prepared casserole dish and spread evenly.

2. Cover tightly with foil.

Step 4: Bake Covered

• Bake covered for 40–45 minutes, or until the rice is tender and most of the liquid is absorbed.

Step 5: Add Cheese & Topping

1. Remove foil and sprinkle with shredded cheese and French fried onions.

2. Return to the oven uncovered for 10–12 more minutes, or until the cheese is melted and golden.

Step 6: Rest and Serve

Let the casserole rest for 5–10 minutes before serving to allow everything to set and thicken slightly.
