French Onion Chicken Rice delivers ultimate comfort with its hearty chicken and rice baked in creamy soups cheese and a savory French onion crunch. This dish comes together fast yet feels so proudly home cooked every time you pull it from the oven. It is the kind of meal that perfectly fits a weeknight or makes everyone at the table feel extra cozy and cared for.
The first time I made this casserole was when our fridge was low and the pantry was full. It quickly became a comfort tradition in my house and even the picky eaters ask for seconds.
Ingredients
- Cooked white rice: delivers fluffiness that absorbs all the savory flavors. Use fresh or leftover rice for best texture
- Shredded cooked chicken: brings protein and heartiness. Rotisserie chicken is convenient and adds extra flavor
- Cream of chicken soup: makes the sauce ultra creamy. Look for one with low sodium if preferred
- French onion soup: contributes bold onion flavor and deep savory notes. Canned versions make prep quick
- Sour cream: adds tang and helps the casserole stay moist
- Shredded mozzarella or Swiss cheese: provides that gooey cheesy melt. Mozzarella is mild while Swiss adds a touch of nutty flavor
- French fried onions: lend an addictive crunch on top. Choose a fresh can for guaranteed crispiness
- Garlic powder and onion powder: amplify the savory flavors without extra chopping
- Salt and black pepper: enhance and balance all the core flavors
- Chopped parsley: offers a pop of fresh color at serving
Step-by-Step Instructions

- Set your oven temperature to 350 degrees F or 175 degrees C. This ensures even baking and the signature cheesy bubbly topping
- Make the casserole mixture:
- In a large bowl add cooked rice shredded chicken cream of chicken soup French onion soup sour cream shredded cheese 1 cup of the French fried onions garlic powder onion powder salt and black pepper. Stir thoroughly until everything is evenly combined for a consistent casserole texture
- Prepare the baking dish:
- Coat a 9 by 13 inch baking dish with a thin layer of oil or nonstick spray. Transfer the casserole mixture into the dish spreading it into an even layer for uniform baking

- Place the dish in your preheated oven and bake uncovered for 30 minutes. The cheese will melt and the edges become bubbly which signals the flavors have melded together
- Add crispy topping:
- Carefully remove the dish and sprinkle the remaining half cup of French fried onions evenly over the surface. Return to the oven for five more minutes so the onions turn golden and crisp
- Finish and serve:
- Once finished take the casserole from the oven. Top generously with chopped parsley before serving hot for the brightest flavor and color contrast

French fried onions are my personal favorite ingredient in this dish. They provide that satisfying bite and finish which always impresses my guests. My son once snuck extra onions from the can before dinner just because he could not resist.
Storage Tips
Leftover casserole keeps well in an airtight container for up to four days in the fridge. To reheat simply cover and warm in a 350 degree oven until hot or microwave individual portions. For best results leave the topping off when freezing and add fresh onions after reheating.
Ingredient Substitutions
If you are out of mozzarella or Swiss try Monterey Jack for a creamy melt. For a dairy-free version use a plant based sour cream and cheese option plus cream of mushroom soup in place of cream of chicken. You can swap rotisserie chicken for leftover turkey or even cooked pork if needed.
Serving Suggestions
This casserole shines with a crisp side salad or roasted vegetables for extra color and nutrition. For brunch a spoonful alongside scrambled eggs or a light fruit salad is a fun twist.
