What Ingredients are in Irresistible French Onion Chicken Casserole?
This mouthwatering casserole brings together the perfect balance of protein, carbs, and veggies in one deliciously comforting dish.
- 1 lb ground chicken
- 10.5 oz French onion condensed soup
- 10.5 oz cream of chicken condensed soup
- â…“ cup sour cream
- ½ tsp black pepper
- ½ tsp garlic powder
- 15 oz can French cut green beans, drained
- 2 cups reduced sodium chicken broth
- ¾ cup uncooked rice
- 2 cups shredded cheddar cheese
- 6 oz crunchy onion toppers
When shopping for ingredients, I recommend sticking with reduced sodium chicken broth as listed, since the condensed soups already contribute plenty of saltiness to the finished casserole—it’s all about finding that perfect flavor balance.
How to Make this Irresistible French Onion Chicken Casserole
Making this comforting casserole is surprisingly simple, even on those nights when you’re wondering what on earth to cook for dinner. Start by preheating your oven to 350°F, then brown 1 lb of ground chicken in a skillet until it’s no longer pink. There’s something so satisfying about watching that chicken transform from raw to perfectly cooked—a little culinary magic happening right on your stovetop.
Next comes the creamy, flavorful base that makes this casserole so crave-worthy. In a large bowl, combine 10.5 oz French onion condensed soup and 10.5 oz cream of chicken condensed soup with ⅓ cup sour cream. Add ½ tsp black pepper and ½ tsp garlic powder for that perfect seasoning balance, then mix in 2 cups reduced sodium chicken broth and a 15 oz can of drained French cut green beans.
Now, stir ¾ cup uncooked rice into your cooked chicken before folding in the soup mixture until everything is beautifully incorporated. For the best results, consider using an enameled cast iron Dutch oven which distributes heat evenly and helps the casserole cook perfectly. Spread this mixture evenly in a greased 9×13 baking dish—and yes, taking an extra moment to guarantee your rice is distributed evenly throughout will ensure more consistent cooking, no crunchy surprises in your finished casserole.
Cover the dish tightly with foil (a pivotal step for properly cooking the rice) and bake for 45 minutes. When the timer dings, remove the foil and prepare for the crowning glory: sprinkle 2 cups of shredded cheddar cheese over the top, followed by 6 oz of crunchy onion toppers. These golden, crispy bits are what elevate this dish from merely delicious to absolutely irresistible. Return the uncovered casserole to the oven for 15 more minutes, until the cheese is melted and bubbly and those onion toppers have turned a beautiful golden brown. Let it rest for just a few minutes before serving—though the heavenly aroma might make that the hardest part of the entire recipe.
What to Serve with Irresistible French Onion Chicken Casserole
Although this chicken casserole stands beautifully on its own as a one-dish wonder, pairing it with the right sides can transform dinner into something truly special. I’m a big fan of serving a crisp garden salad with a light vinaigrette to balance the rich, creamy texture of the casserole. Fresh crusty bread makes the perfect companion, too—ideal for sopping up those delicious juices.
For a heartier meal, roasted vegetables like asparagus or Brussels sprouts add color and nutrition. Want something simpler? A side of garlic bread and steamed broccoli works perfectly, no fuss required.
Leftovers and Storage for this Irresistible French Onion Chicken Casserole
How long will this heavenly casserole last in your refrigerator? I’m happy to report you can enjoy it for up to 4 days when stored in an airtight container. The flavors actually get better overnight as everything melds together—making it perfect for meal prep.
For longer storage, I recommend freezing portions in freezer-safe containers for up to 3 months. When reheating, add a splash of broth if it seems dry. The microwave works for quick fixes, but for best results, warm it in the oven at 325°F until bubbly. Those crispy onions might lose some crunch, though!
Irresistible French Onion Chicken Casserole Substitutions and Variations
Now that you know how to store this delicious dish, let’s explore ways to make it your own!
You can swap ground chicken for turkey or beef if that’s what’s in your fridge. No French onion soup? Cream of mushroom works in a pinch. Brown rice can replace white rice – just add 10 minutes to your baking time. Vegetarians might enjoy using plant-based ground “meat” and vegetable broth.
For different flavor profiles, try pepper jack cheese instead of cheddar, or add diced bell peppers for extra color. Can’t find crunchy onion toppers? Crushed potato chips or breadcrumbs mixed with a little butter create that perfect crispy topping.
Final Thoughts

The combination of savory ground chicken, creamy soups, and that irresistible crunchy onion topping creates a dinner that’ll have everyone asking for seconds. What I love most about this dish? It’s incredibly forgiving and adaptable to what you have on hand. For a different flavor profile, consider trying a ranch seasoning blend that pairs beautifully with chicken and bacon in casseroles.
