• 1/2 cup grated Parmesan cheese

How to Make French Onion Chicken Orzo Casserole

1. Caramelize the Onions
   In a large oven-safe skillet or Dutch oven, melt the butter and olive oil over medium heat. Add the sliced onions, sugar, and salt. Cook for 20–25 minutes, stirring occasionally, until the onions turn a deep golden brown and develop a luscious caramelization. Stir in the minced garlic for the last 1–2 minutes, allowing its fragrant aroma to mingle with the sweet onions.

2. Add Orzo and Chicken
   Stir in the orzo and let it toast lightly for about 2 minutes. This step enhances the flavor, giving the orzo a slightly nutty taste. Next, add the shredded chicken, thyme, and black pepper. If you’re using Worcestershire sauce or balsamic glaze, now’s the time to drizzle it in. Mix everything together until well combined.

3. Pour in Liquids
   Add the chicken broth and cream, gently bringing the mixture to a simmer. Lower the heat, cover the skillet, and let it cook for about 8–10 minutes, stirring occasionally until the orzo is tender and absorbs most of the liquid.

4. Add Cheese
   Stir in 1 cup of mozzarella cheese along with the parmesan. Mix until melted and creamy, creating a luxurious sauce that envelops the orzo and chicken.

5. Bake the Casserole
   Preheat your oven to 375°F (190°C). Once preheated, sprinkle the remaining 1/2 cup of mozzarella on top of the casserole. Bake uncovered for 10–15 minutes until bubbly and golden.

6. Serve
   Allow the casserole to rest for 5–10 minutes before serving. Garnish with fresh thyme or parsley for a pop of color and freshness.

Chef’s Notes & Helpful Tips

• Make-ahead tips: Prepare the casserole earlier in the day, store it in the fridge, and bake it just before serving for minimal fuss.
• Cooking alternatives: This casserole can also be made in an air fryer, reducing bake time while producing that same crispy cheese top.
• Customization ideas: Feel free to add sautéed mushrooms, spinach, or bell peppers for additional flavors and nutrition.

Common Mistakes to Avoid

• Overcooking the onions: Keep an eye on them to avoid burning; they should caramelize slowly to bring out their sweet flavor.
• Not stirring the orzo enough: Stir occasionally during simmering to prevent the pasta from sticking together.
• Skipping the resting period: Allowing the casserole to rest helps it set up, making it easier to serve.
