Why You’ll Love This Recipe
I love how this recipe transforms basic ingredients into something deeply flavorful. The slow-cooked onions melt into sweet, savory goodness while the chicken becomes incredibly tender. Orzo absorbs all the rich flavors and gets creamy with a splash of cream and Parmesan. The final broiled Gruyère topping adds a golden, cheesy finish I can’t get enough of. It’s perfect when I want a cozy, satisfying meal without standing over the stove.
Ingredients
(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)
3‑4 yellow onions, thinly sliced
6 tablespoons salted butter
1½ pounds boneless chicken breasts or thighs
2 tablespoons fresh thyme leaves
2 tablespoons chopped fresh sage
kosher salt and black pepper, to taste
3 cloves garlic, chopped
1 cup dry white wine
1 cup chicken or vegetable broth
2 cups sliced mushrooms
2 cups dry orzo pasta
½ cup heavy cream
½ cup grated Parmesan cheese
1 cup shredded Gruyère cheese
Directions
I start by layering the sliced onions and 3 tablespoons of butter in the base of my slow cooker, then place the chicken on top. I sprinkle it with thyme, sage, garlic, and season it well with salt and pepper.
Next, I pour in the wine and broth, add the mushrooms, then cover and cook on low for 3–4 hours or high for 1–2 hours until the chicken is tender.
Once the chicken is cooked, I remove it along with most of the onions and set them on a baking sheet.
I increase the slow cooker to high heat and stir in the orzo with 1 cup of water. I cover and cook it for 20–30 minutes, checking to make sure it stays moist and adding more liquid if needed. Once al dente, I stir in the cream and Parmesan.
Meanwhile, I dot the onions on the baking sheet with the remaining 3 tablespoons of butter and sprinkle Gruyère on top. I broil them for 3–5 minutes until the cheese is melted and golden.
Finally, I serve the chicken and broiled onions over the creamy orzo, and sometimes add a touch of fresh thyme or parsley for garnish.

Variations
I sometimes swap the chicken for boneless thighs if I want something even juicier. If I’m out of Gruyère, I’ll use Swiss or even mozzarella for the broiled topping. For a gluten-free twist, I replace the orzo with rice or gluten-free pasta. I’ve also made this entirely on the stovetop when I’m short on time—just a few tweaks, and it still turns out delicious.
Storage/Reheating
Leftovers keep well in an airtight container in the fridge for up to 3 days. When I reheat it, I do so gently on the stovetop or in the microwave, adding a splash of broth or cream to loosen up the orzo. It doesn’t freeze well because of the dairy, so I like to enjoy it fresh or within a few days.
FAQs
How can I make this recipe without wine?
I replace the white wine with additional broth or a splash of white grape juice with a bit of vinegar for acidity.
Can I use frozen chicken?
I don’t recommend using frozen chicken in a slow cooker due to safety concerns. I always thaw it first.
What can I use instead of Gruyère cheese?
I’ve used Swiss, mozzarella, or even provolone with good results. Gruyère adds that nutty flavor, but other melty cheeses work too.
Can I make this dish vegetarian?
Yes, I omit the chicken and use extra mushrooms or even white beans for protein. I also use vegetable broth.
How do I prevent the orzo from getting mushy?
I keep an eye on it during cooking and make sure not to overcook it. I also add just enough liquid and stir occasionally to check the texture.
Conclusion
This slow cooker French onion chicken with creamy orzo is one of those recipes I keep coming back to. It’s rich, flavorful, and surprisingly simple to prepare. Whether I’m feeding the family or want something special on a weeknight, it always hits the spot.
A comforting one‑pot dish combining French onion–style chicken with creamy parmesan orzo in a slow cooker.
Ingredients
3‑4 yellow onions, thinly sliced
6 tablespoons salted butter
1½ pounds boneless chicken breasts or thighs
2 tablespoons fresh thyme leaves
2 tablespoons chopped fresh sage
kosher salt and black pepper, to taste
3 cloves garlic, chopped
1 cup dry white wine
1 cup chicken or vegetable broth
2 cups sliced mushrooms
2 cups dry orzo pasta
½ cup heavy cream
½ cup grated Parmesan cheese
1 cup shredded Gruyère cheese
Instructions
In the bowl of your slow cooker, layer the onions, 3 tablespoons butter, and then the chicken. Sprinkle the chicken with thyme, sage, garlic, and season with salt and pepper. Pour the wine and broth over, and add the mushrooms. Cover and cook on low for 3‑4 hours or on high for 1‑2 hours.
Preheat the broiler to high. Remove the chicken and most of the onions from the slow cooker and place on a baking sheet.
Increase slow cooker heat to high. Stir in the orzo and 1 cup water. Cover and cook 20‑30 minutes until orzo is al dente. Add more liquid if needed. Then stir in the cream and Parmesan cheese.
On the baking sheet with the onions, dot with the remaining 3 tablespoons of butter and top with Gruyère. Broil for 3‑5 minutes, until the cheese is melty and onions are slightly darkened.
Serve the chicken and onions over the creamy orzo. Garnish with fresh thyme or parsley, if desired.
Notes
You can also make this on the stovetop: sauté the onions in butter, then add chicken, herbs, wine, broth, mushrooms; simmer until chicken is cooked. Remove chicken and broil onions + cheese. Cook orzo separately and mix with remaining liquid, cream, Parmesan. Serve.
If the orzo needs more liquid during cooking, add additional water or broth.
For a gluten‑free version, use a substitute for orzo (e.g. small rice or gluten‑free pasta).
