Gather These Items

To prepare this delightful casserole, gather the following ingredients:

• 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 wonderfully)
• 1/2 teaspoon dried thyme
• 1/4 teaspoon black pepper
• 2 cups low-sodium chicken broth
• 1 cup heavy cream (or use half and half for a lighter option)
• 1 1/2 cups shredded mozzarella cheese
• 1/2 cup grated Parmesan cheese
• Optional: 1/2 teaspoon Worcestershire sauce or balsamic glaze for added depth

Directions to Follow

1. 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 of cooking.

2. Add Orzo and Chicken: Stir in the orzo and cook for 2 minutes, allowing it to lightly toast. Next, add the shredded chicken, thyme, pepper, and Worcestershire sauce if desired. Mix everything well.

3. Pour in Liquids: Add the chicken broth and cream to the mixture. Bring to a gentle simmer. Reduce the heat to low, cover, and let it cook for 8–10 minutes, stirring occasionally, until the orzo is tender.

4. Add Cheese: Stir in 1 cup of mozzarella and the Parmesan cheese. Mix until melted and creamy.

5. 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 on top.

6. Serve: Allow the casserole to rest for 5–10 minutes before serving. You can garnish it with fresh thyme or parsley if you like for an added touch of freshness!

Best Ways to Enjoy It

Serve the French Onion Chicken Orzo Casserole as a hearty main dish. It pairs wonderfully with a crisp green salad for a balanced meal, or you could complement it with roasted vegetables for some added texture. If you’d like to elevate your dining experience, a glass of white wine, such as Chardonnay, would beautifully complement the rich flavors of this dish.

Storage and Reheating Tips

If you have any leftovers, the good news is that this casserole keeps well! Allow it to cool completely before transferring it to an airtight container. It can be stored in the refrigerator for up to 3–4 days. When you’re ready to enjoy it again, simply reheat in the oven at 350°F (175°C) until warmed through. You can also freeze portions for up to 2 months—just be sure to use freezer-safe containers to prevent freezer burn.

Helpful Cooking Tips

To ensure your casserole comes out perfectly:

• When caramelizing the onions, patience is key. Stirming occasionally and allowing them to develop a deep color will enhance the flavor.
• For a slightly different flavor profile, feel free to use different cheeses like Gruyère or fontina for a unique twist!
• If you prefer a healthier version, consider using whole wheat orzo, which adds extra fiber.
