I am a BIG FAN of anything French Onion, my family, however, are not. So when I get the chance to make this French Chicken and Rice Casserole, I take it! It’s simple because everything you need for the main dish cooks together in one pan. You get tender chicken, savory rice, plenty of French onion flavor, melted cheese, and that crispy fried onion topping that (if you ask me) might just be the best part.
I especially like casseroles like this for busy nights because there isn’t a long list of separate sides or components to make. Once everything is assembled, the oven does the rest of the work. This French onion chicken casserole is also a complete chicken-and-rice dinner in one baking dish. The rice cooks right alongside the chicken and absorbs all of that flavor from the broth, onion soup mix, sliced onions, and canned French onion soup.
It reminds me of why recipes like my Easy Tater Tot Casserole and Creamy Rotel White Chicken Spaghetti Bake work so well for family dinners—they’re filling, comforting, and don’t require spending the whole evening in the kitchen.
Why You’ll Love This Recipe
- It’s a true one-dish dinner. The chicken and rice cook together in the same baking dish, which means less cleanup afterward.
- The rice has tons of flavor. Instead of cooking in plain water, it absorbs the broth, onion soup mix, and all those savory juices as the casserole bakes.
- It has plenty of French onion flavor. You get sliced onion, French onion soup, onion soup mix, and crispy fried onions all in one recipe.
- That crispy topping makes a difference. The fried onions aren’t added until near the end so they stay crisp and golden.
- It’s easy to prep. Most of the work is simply adding everything to the casserole dish and getting it into the oven.
- It’s a hearty family dinner. Chicken, rice, and cheese make this filling enough to serve as the main part of the meal.

You’ll want to sliver your onion like this.
Equipment
9×13 inch Baking Dish: This is the main piece of equipment you’ll need. A ceramic or glass casserole dish works well and gives the rice enough room to cook evenly around the chicken.
Aluminum Foil: Don’t skip the foil for this recipe. You need to cover the baking dish securely so the steam stays trapped inside and cooks the rice.
Fine-Mesh Strainer: Helpful for rinsing the long-grain rice thoroughly and allowing the excess water to drain before it goes into the casserole.
Meat Thermometer: The easiest way to know your chicken is completely cooked is to check the thickest part with an instant-read meat thermometer. Chicken should reach an internal temperature of 165°F.
How to Make French Onion Chicken and Rice Casserole
The way you layer this casserole matters because the rice needs plenty of liquid and trapped steam to cook properly.
Start with the rice mixture directly in your baking dish. The sliced yellow onion, dry onion soup mix, broth, and rinsed and drained long-grain rice are mixed together so the seasonings and liquid are evenly distributed. This gives the rice a chance to absorb all of that savory flavor while it cooks instead of being an afterthought underneath the chicken.
The chicken goes directly on top of the rice mixture. Try to use pieces that are relatively even in thickness so you don’t end up with thinner pieces overcooking while you’re waiting for a very thick chicken breast to finish. Top with sliced butter.
Once the chicken and butter is in place, add the canned French onion soup followed by the shredded cheese.
As everything bakes, the butter, cheese, and soup melt together over the chicken while the rice cooks underneath.
The most important part comes right before the casserole goes into the oven: cover that baking dish tightly with foil.You don’t want steam escaping around loose edges. That trapped moisture is what allows the uncooked rice to become tender in the oven.
Leave the crispy fried onions off during this first part of baking. Once the chicken and rice have had time to cook covered, remove the foil and scatter the fried onions across the casserole. The final uncovered bake crisps and toasts the onions while allowing the top of the casserole to brown.
Before serving, check the thickest portion of the chicken with a meat thermometer to make sure it has reached at least 165°F. The rice should be tender and have absorbed the liquid rather than being soupy.
Scoop, garnish and enjoy!

- Cook Time: 1 hour 25 minutes
- Total Time: 1 hour 35 minutes
- Yield: 8 servings
- Category: Dinner
- Method: Baking
- Cuisine: American
Ingredients
- 1 small yellow onion, thinly sliced
- 1 (10.5-ounce) can French onion soup
- 16 ounces chicken or beef broth, regular or low-sodium
- 1 ¼ cups long-grain white rice, rinsed and drained
- 2 pounds boneless, skinless chicken breasts or thighs
- ¼ cup butter, sliced
- 1 ½ cups shredded Italian cheese blend or mozzarella cheese
- 1 (1-ounce) packet onion soup mix
- 3 ounces crispy fried onions
Instructions
- Preheat the oven to 350°F.
- Add the sliced onion, French onion soup mix packet, broth, and rinsed rice to a 13×9-inch baking dish and mix to combine.
- Place the chicken on top of the rice mixture.
- Top the chicken with the sliced butter, shredded cheese, and the can of French onion soup.
- Cover the baking dish tightly with aluminum foil and bake for 1 hour 10 minutes.
- Cover tightly: Be sure to cover the baking dish tightly with aluminum foil during the first part of baking. Trapping the steam inside the dish is important for cooking the rice properly.
- Carefully remove the foil and sprinkle the crispy fried onions evenly over the casserole.
- Return to the oven, uncovered, and bake for another 15 minutes, or until the chicken reaches an internal temperature of 165°F and the rice is tender.
Notes
- Rice: Use regular long-grain white rice rather than instant rice. Rinse and drain it well before adding it to the casserole.
- Chicken: Chicken breasts or thighs will both work. If using especially thick chicken breasts, cut or pound them to a more even thickness so they cook consistently.
- Chicken thickness: For even cooking, use chicken breasts or thighs that are approximately ½-inch thick. If your chicken breasts are especially thick, slice them horizontally or pound them to an even thickness before assembling the casserole.
- Cheese: Use shredded mozzarella or an Italian cheese blend.
- Broth: Chicken or beef broth works. Low-sodium broth can be used if you want more control over the salt level.
- Don’t uncover early: Keeping the dish tightly covered during the first part of baking traps the steam needed to cook the rice.
- Doneness: Always check the thickest part of the chicken with a meat thermometer. It should reach at least 165°F before serving.
Recipes That Pair Well With This
This casserole already gives you chicken and rice in one dish, so I usually keep the sides fairly simple. Vegetables, salads, and bread are especially good choices.
- Corn on the Cob – A simple vegetable side that gives you four different cooking methods depending on what else you have going on in the kitchen.
- Garlic Parmesan Green Beans – Since the chicken and rice are already together in the casserole, these buttery garlic Parmesan green beans are an easy way to add a vegetable to the meal.
- Strawberry Feta Salad with Strawberry Vinaigrette – The fresh fruit and tangy dressing are a nice contrast to a rich, savory casserole.
- Easy Homemade Breadsticks – Homemade breadsticks are perfect when you want to turn the casserole into an extra-comforting dinner.

Tips for Little Helpers
This is a good recipe for little helpers because most of the prep involves measuring, pouring, and layering rather than working over a hot stove.
Younger kids can help rinse the rice, sprinkle in the onion soup mix, pour in the broth, or spread the crispy fried onions over the casserole before its final trip to the oven.
Older kids can practice slicing the butter or measuring ingredients with supervision. They can also help learn how to use a meat thermometer to check whether chicken has reached a safe internal temperature.
Keep little hands away from the hot baking dish when removing the foil. A lot of steam is trapped underneath, and it will escape quickly when the foil is lifted.
Tips for Success
Cover the dish tightly. This is probably the most important tip for this recipe. The rice depends on the steam trapped inside the baking dish to cook. Crimp the foil securely around the edges rather than loosely laying it over the top.
Use the right rice. Regular long-grain white rice works best. Instant or Minute Rice cooks differently and can become mushy with this cooking method.
Rinse your rice. Rinse the rice thoroughly and drain it before adding it to the baking dish.
Watch the thickness of your chicken. Aim for chicken that’s approximately ½-inch thick. Very thick chicken breasts can throw off the cooking time because the rice may be ready before the center of the chicken is done.
Don’t add the crispy onions at the beginning. They go on toward the end so they can toast without soaking up all the moisture underneath the foil.
Check the chicken, not just the clock. Oven temperatures and chicken thickness can vary. Use a meat thermometer and make sure the thickest portion of the chicken reaches at least 165°F.
Be careful with additional salt. The broth, French onion soup, onion soup mix, cheese, and fried onions all bring seasoning to the casserole. Taste before adding extra salt at the table.
Give the rice a quick check before serving. It should be tender and the majority of the liquid should be absorbed. If your rice still seems firm, cover the casserole again and give it a little additional baking time.
FAQs
Can I use chicken thighs instead of chicken breasts?
Yes. Boneless, skinless chicken thighs work well in French Onion Chicken and Rice Casserole. Just like with chicken breasts, make sure the chicken reaches an internal temperature of at least 165°F before serving.
Can I use Minute Rice?
I don’t recommend it. This recipe was made with regular long-grain white rice. Instant rice cooks much faster and can become mushy during the longer covered baking time.
Do I need to cook the rice before adding it?
No. The rice goes into the casserole uncooked. It cooks in the broth and other liquids while the casserole is tightly covered in the oven.
Why does the casserole need to be covered so tightly?
The foil traps steam inside the baking dish, and that moisture is essential for properly cooking the rice. A loose cover can allow too much steam to escape.
Can I use beef broth instead of chicken broth?
Yes. Either works. Beef broth gives the casserole a slightly richer, deeper flavor, while chicken broth has a milder flavor.
Can I use mozzarella instead of an Italian cheese blend?
Yes. Either shredded mozzarella or an Italian cheese blend works well in this recipe.
Can I use homemade French onion soup?
Yes. Homemade French onion soup can be substituted for canned as long as it has a similar consistency and provides enough liquid for the casserole.
Should I season the chicken before baking?
You can add a little extra seasoning if you prefer, but keep in mind that several ingredients in the casserole are already well seasoned. The onion soup mix, broth, canned soup, cheese, and fried onions add plenty of flavor and can also contribute quite a bit of salt.
Why are the fried onions added at the end?
Adding them near the end of the baking time keeps them crisp. Putting them underneath the foil for the entire cooking time would expose them to steam and moisture and make them soft.
What should I do if my rice isn’t completely cooked?
Cover the casserole tightly again and continue baking until the rice is tender. Rice can occasionally take a little longer depending on the baking dish, oven, and how securely the dish was covered.
Storage
Allow leftover French Onion Chicken and Rice Casserole to cool before transferring it to an airtight container. Store leftovers in the refrigerator.
For easy lunches, you can portion the chicken and rice into individual containers. When reheating, adding a small splash of broth can help loosen rice that has absorbed more liquid while sitting in the refrigerator.
The crispy fried onions will soften somewhat during storage, so you can add a few fresh crispy onions after reheating if you want to bring some of that crunch back.
Freezing Instructions
French Onion Chicken and Rice Casserole can be frozen after it has been fully cooked and cooled. Transfer individual portions or larger amounts to freezer-safe airtight containers.
Keep in mind that cooked rice can become slightly softer after freezing and reheating, and the crispy fried onion topping won’t have quite the same texture after being frozen.
For the best topping, freeze the casserole without adding extra fried onions for reheating. Once the casserole is hot, sprinkle fresh crispy fried onions over the top before serving.
Thaw frozen leftovers in the refrigerator before reheating for the most even results.
Variations
Use chicken thighs: Swap boneless, skinless chicken breasts for boneless, skinless thighs for a slightly richer chicken flavor.
Change the cheese: Mozzarella and an Italian cheese blend both work well, but you can experiment with another mild melting cheese if that’s what you have on hand.
Use beef broth: Choose beef broth instead of chicken broth when you want to lean even further into the rich French onion flavor.
Use homemade French onion soup: Replace the canned soup with homemade French onion soup for a from-scratch option.
Add mushrooms: Sliced mushrooms would pair naturally with the onion, chicken, and savory broth flavors. Keep in mind that mushrooms release moisture as they cook, so I wouldn’t add a large amount without retesting the liquid-to-rice ratio.
Final Thoughts
French Onion Chicken and Rice Casserole takes some of my favorite comfort-food flavors and turns them into an easy family dinner. The rice soaks up all that savory onion flavor while the chicken cooks on top, and the melted cheese and crispy fried onions give the casserole a really good combination of creamy and crunchy textures.
The biggest thing to remember is to keep that foil tightly sealed while the rice cooks and wait until the end to add the crispy onions. Those two little details make a big difference in the finished casserole.
It’s hearty enough to stand on its own for a busy weeknight, but add a vegetable, salad, or some homemade bread and you’ve got a complete family dinner without making a bunch of separate dishes.
