French Onion Chicken and Orzo (Dump and Bake)
on Nov 06, 2026
Anyone looking for a dump and bake ONE PAN MEAL?!! This Modern Nonna INVENTION has all the flavors of French onion soup, baked into a complete meal! My French Onion Chicken and Orzo starts with thinly sliced onions 🧅 that soften and turn golden in the oven. Then, the chicken and uncooked orzo bake right in the beef broth before a layer of Gruyère 🧀 gets melted and browned under the broiler.
The best part? We’re letting the oven do most of the work 🙌! You’ll need to stir the onions once or twice and give the dish a 10 minute rest before serving, but there’s no standing over the stove stirring onions for an hour.
One dish + a few simple steps = a seriously cozy dinner ❤️.

Why You’ll Love this French Onion Chicken and Orzo
- No stovetop required! We soften the onions right in the oven, so there’s no need to babysit a skillet 🙌. Just give them a stir once or twice as they cook.
- All the French onion flavor. Sweet, softened onions 🧅, roasted garlic, beef broth, thyme, and Gruyère give this dish that familiar French onion soup-inspired flavor.
- The orzo cooks in the broth. No boiling a separate pot of pasta! The uncooked orzo goes straight into the baking dish with the chicken.
- A complete meal in one dish. Tender chicken thighs, pasta, and a beautiful layer of melted cheese make this a comforting dinner all on its own.
- That cheesy finish! A quick trip under the broiler melts and browns the Gruyère 🧀 for that iconic French onion soup topping.
Ingredients You’ll Need
🧅 Yellow Onions: These are the star of the show! Slice them as thinly and evenly as you can so they soften at a similar rate. I recommend using a mandoline because it makes this step SO much easier. Always be sure to use the safety guard.
🧄 Garlic: We’re using three whole garlic cloves with their skins on. They roast alongside the onions until softened, and then we squeeze the garlic right out of the skins.
🍚 Orzo: This little rice-shaped pasta cooks directly in the broth. Make sure you’re adding it uncooked!
💧 Low-Sodium Beef Broth: This is my preferred choice for that classic French onion soup flavor. You can use chicken or vegetable broth instead, but the flavor will be different.
🥛 Heavy Cream or Extra Broth: The recipe gives you the option of using ¼ cup heavy cream or ¼ cup additional beef broth. The extra broth is in addition to the main 3 cups, not a replacement for them.
🍗 Boneless, Skinless Chicken Thighs: Cut them into pieces about 2 inches in size. This matters because we’re cooking the chicken and orzo together, and larger chicken pieces can take longer to cook.
🧀 Gruyère Cheese: Rich, nutty, and beautifully melty! It’s the perfect French onion-inspired topping. You can also use mozzarella, Parmesan, or another nutty grated cheese, just keep in mind that different cheeses will melt differently.
🍋 Thyme, Butter, and Lemon: A pinch of fresh or dried thyme and a tablespoon of butter add that lovely savory richness. I also love the option of serving this with fresh lemon wedges. A little squeeze at the end adds brightness and balances all those rich flavors.
Nonna’s Tip 🧅
I love using a mandoline to make my onions nice and thin. The thinner and more evenly they’re sliced, the faster they’ll soften in the oven and the more evenly they’ll cook. Trust me, it’s worth the cleanup…even if your mandoline takes forever to dry 😂!
How to Caramelize Onions in the Oven
If you’ve ever made French onion soup, you know that caramelizing the onions takes patience 🫠. But here’s the beauty of this recipe: we’re letting the oven do all the work!
First Bake: Start by tossing your thinly sliced yellow onions with olive oil, salt, and three whole garlic cloves (skins on) in a lightly greased baking dish. Cover with foil and bake at 400°F (200°C) for 50 to 70 minutes, giving the onions a stir once or twice along the way. You’ll know they’re ready when they’ve reduced by about half, become nice and soft, and started turning golden.
Second Bake: Once the onions are ready, we’ll lower the oven temperature to 375°F (190°C) before adding the chicken, orzo, and broth for the second bake. Don’t add everything at the beginning! Giving the onions that head start is an important part of building the flavor in this dish 🤤.
Tips for Baking Chicken and Orzo in the Same Dish
The beauty of this one pan wonder is that the chicken and orzo cook together in the same baking dish 🍗! Here are a few tips to get them just right:
- Keep the chicken pieces about 2 inches. Larger pieces take longer to cook, which could leave you with overcooked orzo.
- Cover tightly with foil. Give everything a good stir before covering so the orzo can cook in that flavorful broth.
- Check for doneness. The orzo should be cooked to your liking, and the thickest chicken piece must reach 165°F (74°C) on a meat thermometer. Don’t rely on the timer alone!
- Broil only when fully cooked. Once the chicken and orzo are done, add the Gruyère and broil until melted and golden.
- Don’t skip the 10-minute rest! The orzo continues absorbing the broth as it sits, so give it a few minutes before digging in.
Best Served With
- Want to sneak in some veggies? Add frozen peas, chopped spinach 🥬, quartered artichoke hearts, or thinly sliced bell peppers with the chicken, broth, and orzo.
- Love mushrooms 🍄? Sauté them separately before adding them in for max flavor.
- This dish is a complete meal on its own, but my Simple Green Salad 🥗 makes a fresh, crisp addition – the perfect contrast next to the rich French onion flavors.
- For another oven-baked onion pasta, try my Caramelized Onion Pasta made with bow-ties, Boursin, and sun-dried tomatoes.

Common Questions
Do I Need to Cook the Orzo First?
Nope! 🙌 Add the uncooked orzo directly to the baking dish with the chicken and broth after the onions have baked. No separate boiling needed!
Can I Use Rice Instead of Orzo?
I wouldn’t recommend it! This recipe was tested with orzo, and rice requires different cooking times and liquid amounts.
Can I Skip the Heavy Cream?
Absolutely! You can use ¼ cup additional beef broth instead of the cream, on top of the original 3 cups.
Can I Add Vegetables?
Yes! Try frozen peas, chopped spinach, quartered artichoke hearts, or thinly sliced bell peppers. Add them with the chicken, orzo, and broth without overcrowding the dish. For mushrooms, sauté them separately first!
French Onion Chicken and Orzo (Dump and Bake)
Ingredients
- 1 tablespoon olive oil, plus more for greasing the pan
- 1 pound yellow onions, thinly sliced (ideally on a mandoline)
- 3 whole cloves garlic, skin-on
- ½ teaspoon salt, plus more for seasoning
- 1 ½ cups orzo
- 3 cups low-sodium beef broth
- ¼ cup heavy cream or ¼ cup more beef broth
- 1 pound boneless skinless chicken thighs, cut into 2-inch pieces
- 1 tablespoon butter, cut into small pieces
- pinch of fresh or dried thyme
- 1 cup shredded gruyere cheese
- Lemon wedges for serving, optional
Instructions
- Preheat the oven to 400F (200C).
- Grease a large baking dish (at least 9×9) with a thin layer of oil. Add the onions, skin-on garlic cloves, olive oil, and salt. Mix to combine well. Cover with foil and bake for 50 to 70 minutes, or until the onions have reduced by about half, softened, and are starting to golden. I like to stir the onions 1 to 2 times throughout the baking time.
- Remove the dish from the oven and reduce the heat to 375F (190C). Using tongs or a fork, transfer the cooked garlic to a plate or cutting board and let cool for a few minutes.
- Working carefully so as not to burn yourself, to the hot baking dish, add the orzo, broth, chicken, butter, and thyme and season to taste with salt and pepper. Carefully squeeze the hot baked garlic from its skin and add that to the dish. Stir everything well. Cover the baking dish tightly with foil and return to the oven.
- Bake for 35 to 40 minutes, until the orzo is cooked to your desired doneness and the chicken is fully cooked (the juices should run clear when cut into with a knife and a meat thermometer inserted in the thickest part of a piece of chicken measures 165F [80C]).
- Carefully remove the pan from the oven and take off the foil. Set the broiler to high. Sprinkle the orzo all over with the shredded gruyere. Return the dish to the oven (uncovered), and let broil until the cheese is melty and starting to brown, 2 to 4 minutes.
- Remove the dish from the oven and let rest for 10 minutes. Squeeze the lemon wedges over the top, if using.
Nonna’s Notes
- Using a mandoline slicer is a quick way to make even-sized, super-thin slices of onion. The thinner the onion slices, the faster they caramelize in the oven.
- The chicken is cut into cubes for even and quicker cooking. Pieces larger than 2-inch chunks will require a longer cooking time, which may cause the orzo to overcook.
- This recipe has been developed and tested with orzo, a tiny pasta shaped like rice. While rice would likely work here, it may impact the quantity of liquid needed and cook time.
- Want to add more vegetables to this dish? Frozen peas, roughly chopped fresh spinach, frozen or canned, quartered artichoke hearts, or thin strips of bell pepper all work well here. Stir your vegetable of choice into the orzo, along with the chicken and broth. You could also separately saute some mushrooms and add them into the orzo.
- Gruyere lends that classic french onion soup flavor: nutty, rich, and smooth. But you can also use shredded mozzarella, parmesan, or another nutty, grated cheese.
- Letting the dish sit at room temp for 10 minutes once out of the oven, allows the orzo to continue absorbing all the delicious broth.
- You can use low-sodium vegetable or chicken broth here, but it won’t give that same classic French Onion flavor that beef stock does.
- The optional lemon wedges squeezed on top of the finished orzo add a bit of brightness and acid to balance out the richness of this dish.
