Ingredients You’ll Need
- 1 ½ pounds boneless skinless chicken breasts
- Slice them into thin cutlets so they cook evenly with the rice.
- You can use boneless skinless chicken thighs if you prefer richer flavor.
- 1 cup long grain white rice, uncooked
- Use regular long grain, not instant or parboiled.
- Jasmine rice also works and adds a light floral note.
- 2 cups low sodium chicken broth
- Low sodium broth gives you better control over salt.
- Use a good quality boxed broth or homemade if you have it.
- 1 can (10.5 ounces) condensed French onion soup
- This shortcut packs in onion flavor without hours of stovetop work.
- Any major brand works; I often use Campbell’s.
- 1 large yellow onion, thinly sliced
- 2 tablespoons butter
- Butter helps the onions brown and adds richness.
- Use unsalted butter so you control the seasoning.
- 1 tablespoon olive oil
- Oil keeps the butter from burning while onions cook.
- 1 teaspoon garlic powder
- 1 teaspoon dried thyme
- Thyme pairs perfectly with onions and chicken.
- Italian seasoning works if you do not have thyme.
- ½ teaspoon paprika
- Paprika adds color and a mild smoky note.
- 1 teaspoon kosher salt, plus more to taste
- ½ teaspoon black pepper
Cheese Topping
- 1 ½ cups shredded Gruyère cheese
- Gruyère gives that classic French onion soup flavor and melts beautifully.
- If you cannot find Gruyère, use Swiss or a blend of Swiss and mozzarella.
- ½ cup shredded mozzarella cheese
- Mozzarella adds stretch and extra melt factor.
- ¼ cup grated Parmesan cheese
- Parmesan adds salty, nutty flavor to the crust.
Optional Add Ins
- ½ cup French fried onions for topping
- These add crunch and extra onion flavor.
- 2 tablespoons chopped fresh parsley
- Sprinkle on top after baking for color and freshness.
Pantry Shortcuts & Substitutions
- Use rotisserie chicken:
- Stir 2 to 3 cups shredded cooked chicken into the rice mixture and reduce bake time by about 10 minutes.
- Use frozen chopped onions:
- Sauté them straight from frozen with butter and oil until golden.
- Use brown rice:
- Increase broth to 2 ½ cups and bake longer, about 70 to 80 minutes, until rice turns tender.
Equipment List
- 9×13 inch baking dish
- Large skillet for onions
- Cutting board and sharp knife
- Mixing bowl (optional, you can mix right in the baking dish)
- Aluminum foil
- Cheese grater if you shred cheese from a block
- Measuring cups and spoons
Tips & Tricks
- Slice chicken into thin cutlets so it cooks through in the same time as the rice.
- Rinse rice under cold water until the water runs clear to prevent gummy texture.
- Sauté onions slowly over medium heat so they turn deep golden and sweet, not burnt.
- Use low sodium broth and condensed soup, then taste and add salt at the end.
- Cover the casserole tightly with foil for the first part of baking so the rice steams and softens.
- Remove foil near the end so the top browns and the cheese forms a bubbly crust.
- Check rice in the center of the pan; if it still feels firm, add a splash of broth and bake a bit longer.
- Let the casserole rest 5 to 10 minutes before serving so the rice sets and scoops cleanly.
- Shred cheese from a block for the best melt; pre shredded cheese often contains anti caking agents.
- Add French fried onions in the last 5 to 10 minutes so they stay crisp and do not burn.
How to Make French Onion Chicken Rice Bake
1: Prep the Oven and Dish
Preheat your oven to 350°F. Grease a 9×13 inch baking dish with a little butter or oil. This keeps the rice from sticking and makes cleanup easier.
2: Slice the Chicken and Onions
Slice chicken breasts into thin cutlets, about ½ inch thick. Pat them dry with paper towels so they brown better and season them with salt, pepper, paprika, and half the garlic powder. Thinly slice the onion from root to tip so you get even strips that cook at the same rate.
3: Cook the Onions
Heat a large skillet over medium heat and add butter and olive oil. Once the butter melts and starts to foam, add the sliced onions and a pinch of salt. Stir often and cook until the onions turn deep golden and caramelized, about 15 to 20 minutes, then stir in thyme and the remaining garlic powder.
4: Mix the Rice Base
Add uncooked rice to the greased baking dish. Pour in chicken broth and condensed French onion soup and whisk or stir until the soup dissolves into the liquid. Taste the liquid and adjust salt and pepper so it tastes well seasoned, since the rice will absorb that flavor.
5: Add Chicken and Onions
Nestle the seasoned chicken cutlets into the rice mixture in a single layer. Spoon the caramelized onions evenly over the top of the chicken and rice. Gently press everything down so the liquid almost covers the chicken.
6: Cover and Bake
Cover the baking dish tightly with foil so steam stays inside. Place it in the oven and bake for 35 to 40 minutes. The rice should absorb most of the liquid and the chicken should cook through.
7: Add Cheese Topping
In a small bowl, mix Gruyère, mozzarella, and Parmesan. Remove the foil from the baking dish and sprinkle the cheese mixture evenly over the top. If you use French fried onions, scatter them over the cheese.
8: Finish Baking
Return the uncovered casserole to the oven and bake another 10 to 15 minutes. The cheese should melt, bubble, and turn lightly golden, and the rice should feel tender when you taste a grain from the center. If you want extra color, you can broil it for 1 to 2 minutes, but watch closely so the top does not burn.
9: Rest
Remove the French Onion Chicken Rice Bake Recipe from the oven and let it rest for 5 to 10 minutes. Sprinkle chopped fresh parsley over the top for a fresh pop of color. Scoop generous portions and enjoy that cheesy, oniony goodness.
What to Serve with French Onion Chicken Rice Bake
This French Onion Chicken Rice Bake Recipe already brings protein, carbs, and cheese to the party, so you only need simple sides. A crisp green salad with a light vinaigrette cuts through the richness nicely. Steamed green beans, roasted broccoli, or a tray of mixed roasted vegetables pair really well. For extra comfort, serve it with warm dinner rolls or garlic bread and a big bowl of fresh fruit on the side.
Storage Options
- Store leftovers in an airtight container in the fridge for up to 3 to 4 days.
- Reheat single portions in the microwave with a splash of broth or water and cover the dish so it stays moist.
- Reheat a larger portion in the oven at 325°F, covered, until hot in the center, then uncover for a few minutes to refresh the cheese.
- Freeze cooled portions in freezer safe containers for up to 2 months, then thaw overnight in the fridge before reheating.
- If the rice looks dry after chilling or freezing, stir in a spoonful of broth before reheating to bring back that creamy texture.

Ingredients
Instructions
- Preheat the oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish.
- Rinse the uncooked rice under cold water until the water runs mostly clear. Spread the rice evenly in the prepared baking dish and pour the chicken broth over the top; set aside.
- In a large skillet over medium heat, melt the butter with the olive oil. Add the sliced onions, sugar, and half of the salt and pepper. Cook, stirring often, until the onions are deep golden and caramelized, 18 to 22 minutes.
- Stir in the dried thyme and minced garlic and cook for 1 minute until fragrant. Add the Worcestershire sauce, stir to coat the onions, then remove from heat.
- Season the chicken breasts on both sides with the remaining salt, pepper, and the paprika. Cut large breasts in half horizontally if needed so they cook evenly.
- Spoon half of the caramelized onion mixture evenly over the rice in the baking dish. Nestle the seasoned chicken breasts on top of the rice and onions. Spread the remaining onions over the chicken.
- Cover the dish tightly with foil and bake for 30 minutes. Remove the foil and check that most of the liquid has been absorbed and the rice is tender around the edges.
- Sprinkle the Gruyère and Parmesan cheeses evenly over the chicken and rice. Return to the oven, uncovered, and bake for 10 to 15 minutes more, until the cheese is melted and lightly golden and the chicken is cooked through (internal temperature 165°F/74°C).
- Let the bake rest for 5 to 10 minutes before serving to allow the rice to finish steaming. Garnish with chopped fresh parsley if desired and serve warm.
