- 2 tablespoons unsalted butter
- 1 tablespoon olive oil
- 2 large yellow onions (thinly sliced)
- 1 teaspoon sugar
- 1/2 teaspoon salt
- 3 garlic cloves (minced)
- 1 1/2 cups orzo pasta
- 2 cups cooked shredded chicken (rotisserie works well)
- 1/2 teaspoon dried thyme
- 1/4 teaspoon black pepper
- 2 cups low-sodium chicken broth

How to Make French Onion Chicken Orzo Casserole
Caramelize the Onions: In a large oven-safe skillet or Dutch oven, melt the butter and olive oil over medium heat. Add sliced onions, sugar, and salt. Cook for 20–25 minutes, stirring occasionally, until the onions are deeply golden and caramelized. Stir in the minced garlic during the last 1–2 minutes for added aroma and flavor.
Add Orzo and Chicken: Stir in the orzo and cook for 2 minutes, allowing it to lightly toast. Add the shredded chicken, thyme, pepper, and Worcestershire sauce if you’re feeling adventurous. Mix well until everything is nicely combined.
Pour in Liquids: Add the chicken broth and cream. Bring to a gentle simmer, then reduce the heat to low, cover, and let it cook for 8–10 minutes, stirring occasionally, until the orzo is tender and has absorbed the flavors.
Add Cheese: Stir in 1 cup of mozzarella and the grated Parmesan cheese, mixing until everything is melted and creamy, creating a delectable, cheesy embrace.
Bake the Casserole: Preheat your oven to 375°F (190°C). Sprinkle the remaining 1/2 cup of mozzarella over the top of the casserole. Bake uncovered for 10-15 minutes, until bubbly and golden, with a charmingly crusty top that beckons you closer.
Serve: Let the casserole rest for about 5–10 minutes before digging in. If you like, garnish with fresh thyme or parsley; it not only looks lovely but adds a fresh burst of flavor!
Variations & Creative Twists
- Savory Mushroom Addition: Add sautéed mushrooms along with the onions for an earthy twist. The rich umami flavor will elevate the dish to new heights.
- Zesty Spinach: Stir in some fresh or frozen spinach for a pop of color and extra nutrients—plus, it pairs beautifully with the creamy goodness.
- Crunchy Topping: Add a few breadcrumbs mixed with a drizzle of olive oil on top before baking for an extra-crunchy texture.
- Cheesy Southwest Style: Spice things up with the addition of taco seasoning and some cooked corn for a fun southwestern twist.
