• 1 teaspoon sugar
• ½ teaspoon salt
• 3 garlic cloves, minced

For the Main Dish

• 1 ½ cups orzo pasta
• 2 cups cooked shredded chicken (rotisserie recommended)
• ½ teaspoon dried thyme
• ¼ teaspoon black pepper
• 2 cups low-sodium chicken broth

How to Make French Onion Chicken Orzo Casserole

Step 1: 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. When the onions turn deeply golden and caramelized, stir in the garlic during the last 1–2 minutes.

Step 2: Add the Orzo and Chicken

Stir in the orzo and toast for about 2 minutes until lightly golden. Then add the shredded chicken, thyme, pepper, and Worcestershire sauce if using.

Step 3: Pour in the Liquids

Add the chicken broth and cream to the mixture. Bring it to a gentle simmer. Reduce heat to low, cover it up, and cook for 8–10 minutes while stirring occasionally until the orzo is tender.

Step 4: Add the Cheese

Stir in 1 cup of mozzarella along with Parmesan until melted into a creamy consistency.

Step 5: Bake the Casserole

Preheat your oven to 375°F (190°C). Sprinkle the remaining ½ cup mozzarella over the top of your casserole. Bake uncovered for 10–15 minutes until bubbly and lightly golden.

Step 6: Serve

Allow your French Onion Chicken Orzo Casserole to rest for 5–10 minutes before serving. Garnish with fresh thyme or parsley if desired. Enjoy!

Common Mistakes to Avoid

When preparing your French Onion Chicken Orzo Casserole, avoiding common pitfalls can enhance its flavor and texture.

• Skipping the caramelization: Failing to properly caramelize the onions can lead to a lack of depth in flavor. Take your time during this step for that rich taste.
• Using uncooked chicken: If you add raw chicken instead of cooked, it won’t blend well with the other ingredients. Always use shredded, cooked chicken for best results.
• Overcooking the orzo: Cooking orzo too long can make it mushy. Keep an eye on it while simmering to ensure it’s al dente.
• Neglecting seasoning: Forgetting to season adequately will result in a bland dish. Taste and adjust the salt and pepper as needed.
• Not letting it rest: Cutting into the casserole immediately can make it fall apart. Allow it to sit for a few minutes before serving for better structure.
