Step-by-Step Instructions

Preheat the Oven:

Set your oven to 350 degrees Fahrenheit. Give it time to come all the way to temperature so the casserole bakes evenly and gets nice and bubbly.

Prepare the Mixture:

In a large mixing bowl combine the cooked white rice shredded chicken cream of chicken soup French onion soup sour cream shredded cheese one cup of French fried onions garlic powder onion powder salt and pepper. Stir thoroughly until everything is well mixed and looks creamy with no dry spots.

Assemble in the Baking Dish:

Take a 9 by 13 inch baking dish and lightly grease it with oil or nonstick spray. Pour the rice and chicken mixture into the pan and smooth it out to cover the surface evenly from edge to edge.

Bake the Casserole:

Place the dish uncovered on the center rack of your oven. Bake for about thirty minutes. Look for bubbling edges and the cheese melting into everything.

Add Crispy Onions and Finish Baking:

After thirty minutes take the casserole out carefully and sprinkle the remaining half cup of French fried onions evenly across the top. Return the dish to the oven and bake for five more minutes so the onions turn golden and crisp.

Garnish and Serve:

Remove the casserole from the oven and let it sit just a couple of minutes so it sets. Sprinkle chopped parsley over the top for color and freshness. Serve hot scooping generous portions to enjoy all the creamy cheesy layers.

Pin it

French fried onions bring more than just crunch they remind me of cozy holiday meals growing up when that savory aroma always meant something special was coming from the oven. It is the ingredient that takes this casserole from simple to crave-worthy.

Storage Tips

Place leftovers in an airtight container in the refrigerator where they will keep well for up to three days. Reheat portions in the microwave or cover and warm in the oven at three hundred twenty five degrees Fahrenheit to maintain texture. If making ahead assemble but wait to add the final topping of fried onions until right before the last bake.

Ingredient Substitutions

You can use brown rice for a slightly nuttier bite or cooked quinoa if you want more protein. For a lighter option try Greek yogurt instead of sour cream. Both Swiss and mozzarella cheese work beautifully or try provolone for more flavor. Rotisserie chicken makes things easy but any cooked boneless chicken works in this recipe.

Serving Suggestions

This casserole is filling enough to stand alone but pairs well with a simple green salad or roasted vegetables. Warm rolls or crusty bread on the side make for a classic comfort meal. I love serving it at casual get-togethers and family potlucks where it disappears fast.

Cultural Context

French onion flavors originally come from classic French onion soup made with caramelized onions and cheese. This American casserole takes those flavors and combines them with beloved chicken and rice bakes that are mainstays in family kitchens. The fried onions on top are a true retro touch found in many comfort recipes from the 1950s onward.
