Ingredients
- 2 tablespoons unsalted butter
- 1 tablespoon olive oil
- 2 large yellow onions, thinly sliced
- 1 teaspoon sugar
- ½ teaspoon salt
- 3 garlic cloves, minced
- 1½ cups orzo pasta
- 2 cups cooked shredded chicken
- ½ teaspoon dried thyme
- ¼ teaspoon black pepper
- 2 cups low-sodium chicken broth
- 1 cup heavy cream or half-and-half
- 1½ cups shredded mozzarella cheese, divided
- ½ cup grated Parmesan cheese
- ½ teaspoon Worcestershire sauce or balsamic glaze, optional
- Fresh thyme or parsley, optional, for garnish
Instructions
- Caramelize the onions: Melt the butter and olive oil in a large oven-safe skillet or Dutch oven over medium heat. Add the onions, sugar, and salt. Cook for 20–25 minutes, stirring occasionally, until deeply golden and caramelized. Add the garlic during the final 1–2 minutes.
- Toast the orzo: Stir in the orzo and cook for about 2 minutes, stirring frequently, until lightly toasted.
- Add the chicken and seasonings: Stir in the shredded chicken, dried thyme, black pepper, and Worcestershire sauce or balsamic glaze, if using.
- Add the liquids: Pour in the chicken broth and cream. Bring the mixture to a gentle simmer, then reduce the heat to low. Cover and cook for 8–10 minutes, stirring occasionally, until the orzo is tender.
- Make it cheesy: Stir in 1 cup of the mozzarella and all of the Parmesan until the cheeses melt into the creamy orzo.
- Bake: Preheat the oven to 375°F (190°C). Sprinkle the remaining ½ cup mozzarella evenly over the top. Bake uncovered for 10–15 minutes, until bubbling and golden.
- Rest and serve: Let the casserole rest for 5–10 minutes before serving. Garnish with fresh thyme or parsley if desired.
Tips & Tricks
- Give the onions time: Don’t rush the caramelization. The deeper the golden color, the more flavorful the casserole will be.
- Stir the orzo: Orzo can settle and stick to the bottom, so give it an occasional stir while simmering.
- Use leftover chicken: Cooked chicken breast or thigh meat works well. Rotisserie chicken is especially convenient.
- For a lighter casserole: Replace the heavy cream with half-and-half.
- For extra flavor: A small amount of Worcestershire sauce adds savory depth. For a vegetarian-style flavor boost without Worcestershire, balsamic glaze works well.
- Watch the salt: Since chicken broth, Parmesan, and Worcestershire sauce can all contain salt, taste before adding more.
- For a golden top: Broil for 1–2 minutes at the end if you want extra browning, watching carefully to prevent burning.

FAQ
Can I make French Onion Chicken Orzo Casserole ahead of time?
Yes. Prepare the casserole through the cheese-topping stage, cool it, cover, and refrigerate. Bake when ready, adding a few extra minutes if the casserole is cold from the refrigerator.
Can I use rotisserie chicken?
Absolutely. Shredded rotisserie chicken is an easy way to make this recipe quickly. Use plain or lightly seasoned chicken for the best flavor balance.
Why is my orzo still firm?
Orzo cooking time can vary by brand. If it needs more time, add a small splash of warm chicken broth or water, cover, and continue cooking until tender.
Can I use half-and-half instead of heavy cream?
Yes. Half-and-half makes the casserole slightly lighter while still providing a creamy texture.
Can I freeze this chicken orzo casserole?
Yes, although the texture of the creamy sauce may change slightly after freezing and reheating. Cool completely before freezing in an airtight container.
What cheese works instead of mozzarella?
Provolone, mild cheddar, or a combination of mozzarella and Gruyère-style halal-friendly cheese can work well.
Storage
Refrigerator: Store cooled leftovers in an airtight container for up to 3–4 days.
Freezer: Freeze cooled portions in airtight, freezer-safe containers for up to 2–3 months for best quality.
Reheating: Reheat individual portions in the microwave, stirring halfway through. Add a splash of broth or cream if the orzo has thickened. Larger portions can be reheated covered in a 350°F (175°C) oven until hot throughout.
