Preparation Phase & Tools to Use
Before diving into cooking, it’s essential to prepare your kitchen and gather all necessary tools. Start by preheating your oven to 350°F (175°C). Meanwhile, grab a 9×13-inch casserole dish and grease it to prevent sticking. This size is ideal for accommodating all the ingredients while allowing ample space for the casserole to expand as it cooks.
You’ll also need mixing bowls for blending your liquids and dry ingredients, a whisk to ensure everything is smooth, and a spatula or spoon for mixing everything together. It’s helpful to have measuring cups and spoons on hand for accuracy. Preparing your workspace effectively can make the cooking process smoother and more enjoyable. Once everything is ready, you can focus on combining the ingredients without unnecessary interruptions.

Ingredients
- 2 cups cooked and shredded rotisserie chicken
- 1 ½ cups long-grain white rice, uncooked
- 1 (10.5 oz) can cream of chicken soup
- 1 (10.5 oz) can French onion soup
- 1 ¾ cups low-sodium chicken broth
- 1 teaspoon garlic powder
- ½ teaspoon black pepper
- 1 cup shredded mozzarella cheese
- 1 cup shredded cheddar cheese
- ½ cup French fried onions (optional, for topping)
- 2 tablespoons chopped fresh parsley (for garnish)
Instructions
Step 1: Prepare Your Casserole Dish
Start by preheating your oven to 350°F (175°C). While your oven is heating, prepare your casserole dish by greasing a 9×13-inch dish. This helps ensure that your casserole doesn’t stick, making for easier serving and cleaning.
Step 2: Mix the Base Ingredients
In a large mixing bowl, combine the cream of chicken soup with the French onion soup and low-sodium chicken broth. Use a whisk to blend these ingredients until they form a smooth mixture. This will serve as the creamy foundation of your casserole. Once combined, stir in the uncooked long-grain rice, garlic powder, black pepper, and the shredded rotisserie chicken. Ensure that everything is evenly coated in the creamy mixture, as this helps to impart flavor throughout the dish.
Step 3: Assemble the Casserole
After your filling is well-mixed, pour it into the greased casserole dish. Spread the mixture evenly to ensure that all areas of the dish are filled. Once you have a level top, cover the dish tightly with aluminum foil. The foil will help retain moisture and steam the rice as it cooks.
Step 4: Bake to Perfection
Place the covered casserole in the preheated oven and bake for 45 minutes. This step is crucial for allowing the rice to cook and absorb all the rich flavors. Once the time is up, carefully remove the foil. Sprinkle the shredded mozzarella and cheddar cheese evenly over the top of your casserole. This cheesy layer will melt beautifully and create a flavorful crust.
Step 5: Final Touches
Return the uncovered casserole to the oven and bake for an additional 15 to 20 minutes. Keep an eye on it; the mixture should become bubbly and the cheese should be melted and golden brown. For the last five minutes, consider sprinkling the French fried onions on top to give your casserole a delightful crunch.
Step 6: Garnish and Serve
Once baked, remove the casserole from the oven and let it cool for a few minutes. Before serving, garnish with chopped fresh parsley for a burst of color and freshness. Your Cheesy French Onion Chicken Casserole is now ready to be served hot!

Variations
- Protein: Substitute the rotisserie chicken with cooked turkey, ground beef, or even tofu for a vegetarian option.
- Vegetables: Add in vegetables like peas, carrots, or spinach to increase the nutritional value and flavors in your casserole.
- Spices: Experiment with additional spices such as paprika, oregano, or Italian seasoning to elevate the overall taste.
Cooking Notes
- For a creamier texture, consider adding a dollop of sour cream or cream cheese to the mixture.
- If using uncooked rice, ensure it is long-grain for the best consistency; other types may require different cooking times.
- Store leftovers in an airtight container in the fridge for up to 3–4 days or freeze for longer preservation.
Serving Suggestions
- Pair your chicken casserole with a simple green salad for a refreshing balance to the creamy dish.
- Serve with crusty bread or garlic bread for an added crunch.
Tips
- Prepare your ingredients in advance to expedite the cooking process, especially during busy evenings.
- Taste the mixture before baking and adjust seasonings according to your preference.
- For an extra cheese pull, use a combination of different cheese types for topping.
