For the Casserole

  • 2 large yellow onions, thinly sliced
  • 1 teaspoon sugar
  • ½ teaspoon salt
  • 3 garlic cloves, minced
  • 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
  • 1 cup heavy cream (or half-and-half)
  • 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 a large oven-safe skillet or Dutch oven over medium heat. Add the onions, sugar, and salt. Cook for 20–25 minutes, stirring occasionally until 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. Then add the shredded chicken, thyme, pepper, and Worcestershire sauce if using.

Step 3: Pour in the Liquids

Add chicken broth and cream to the mixture. Bring to a gentle simmer. Reduce heat to low, cover, 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 cheese until melted and creamy.

Step 5: Bake the Casserole

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

Step 6: Serve

Allow your casserole to rest for 5–10 minutes before serving. Garnish with fresh thyme or parsley if desired.

How to Perfect French Onion Chicken Orzo Casserole

To ensure your casserole turns out perfectly every time, keep these tips in mind.

  • Caramelize Onions Thoroughly: Take time to caramelize the onions properly; this enhances the sweetness and depth of flavor.
  • Adjust Seasonings: Taste before baking; feel free to add more salt or pepper according to your preference.

  6. Quinoa Salad: A refreshing quinoa salad with diced vegetables provides a nutritious boost.

Common Mistakes to Avoid

When preparing your French Onion Chicken Orzo Casserole, avoiding common pitfalls can elevate your dish. Here are some mistakes to keep in mind:

  • Overcooking the onions: Caramelizing onions too quickly can lead to burnt flavors. Cook them slowly over medium heat until they turn golden and sweet.
  • Skipping the seasoning: Neglecting salt or herbs can leave your casserole bland. Be generous with seasonings like salt, pepper, and thyme to enhance flavors.
  • Using uncooked chicken: Adding raw chicken means it won’t cook properly in the casserole. Always use pre-cooked or shredded chicken for best results.
  • Not stirring enough: Failing to stir while cooking the orzo can result in uneven cooking. Stir occasionally to ensure even absorption of liquids and avoid sticking.
  • Rushing the baking process: Baking time is crucial for achieving a bubbly, golden top. Don’t rush; allow it to bake until perfectly crisp.
