For the Base

• 2 large yellow onions, thinly sliced
• 1 teaspoon sugar
• ½ teaspoon salt
• 3 garlic cloves, minced

For the Pasta and Chicken

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

For the Creamy Sauce

• 2 cups low-sodium chicken broth
• 1 cup heavy cream (or half-and-half)

For Topping

• 1 ½ cups shredded mozzarella cheese
• ½ cup grated Parmesan cheese
• Optional: ½ teaspoon Worcestershire sauce or balsamic glaze

How to Make French Onion Chicken Orzo Casserole

Step 1: Caramelize the Onions

Melt the butter and olive oil in your large oven-safe skillet over medium heat. Add the sliced onions along with sugar and salt. Cook for 20–25 minutes, stirring occasionally until they turn deeply golden brown. In the last 1–2 minutes of cooking, add minced garlic.

Step 2: Add the Orzo and Chicken

Stir in the orzo pasta and toast it for about 2 minutes. Then add your cooked shredded chicken along with dried thyme, black pepper, and Worcestershire sauce if you choose to use it.

Step 3: Pour in the Liquids

Next, pour in the chicken broth and heavy cream. Bring this mixture to a gentle simmer. Afterward, reduce heat to low, cover it up, and let it cook for about 8–10 minutes while stirring occasionally until the orzo becomes tender.

Step 4: Add the Cheese

Once your orzo is tender, stir in 1 cup of shredded mozzarella cheese along with Parmesan until they melt into a creamy sauce.

Step 5: Bake the Casserole

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

Step 6: Serve

Let your casserole rest for about 5–10 minutes before serving. For an added touch of freshness, garnish with chopped thyme or parsley if desired. Enjoy your delicious French Onion Chicken Orzo Casserole!

Common Mistakes to Avoid

When making French Onion Chicken Orzo Casserole, it’s easy to overlook some key steps. Here are common mistakes to avoid for a perfect dish.

• Ignoring onion caramelization: Properly caramelizing onions is essential for depth of flavor. Don’t rush this step; cook them slowly over medium heat until golden brown.
• Using unseasoned chicken: If you skip seasoning your chicken, it may lack flavor. Always season the chicken well before adding it to the casserole for a delicious outcome.
• Overcooking the orzo: Overcooked orzo can turn mushy and ruin your casserole’s texture. Keep an eye on the cooking time and test for tenderness regularly.
• Skipping the cheese mix: Cheese adds creaminess and flavor to the dish. Make sure to mix in both mozzarella and Parmesan until fully melted for best results.
• Not letting it rest: Allowing the casserole to rest after baking helps it set up better. Serve immediately for a gooey texture, but do let it sit for a few minutes first.
