French Onion Chicken Orzo Casserole

Print Recipe

A comforting one-pan casserole combining the rich flavors of French onion soup with chicken and creamy orzo.

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 well)
  • 1/2 teaspoon dried thyme
  • 1/4 teaspoon black pepper
  • 2 cups low-sodium chicken broth
  • 1 cup heavy cream
  • 1 1/2 cups shredded mozzarella cheese
  • 1/2 cup grated Parmesan cheese
  • Optional: 1/2 teaspoon Worcestershire sauce or balsamic glaze

Instructions

  1. Caramelize the Onions: In a large oven-safe skillet, 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 are caramelized. Stir in the garlic during the last 1–2 minutes.
  2. Add Orzo and Chicken: Stir in the orzo and sauté for about 2 minutes. Then, mix in the shredded chicken, thyme, pepper, and Worcestershire sauce if using.
  3. Pour in Liquids: Add chicken broth and cream. Bring to a gentle simmer, cover, and cook for 8–10 minutes, stirring occasionally until the orzo is tender.
  4. Add Cheese: Mix in 1 cup of mozzarella and Parmesan until melted and creamy.
  5. Bake the Casserole: Preheat the oven to 375°F (190°C). Sprinkle the remaining mozzarella over the top and bake uncovered for 10–15 minutes until bubbly and golden.
  6. Serve: Let it rest for 5–10 minutes before serving, garnished with fresh thyme or parsley if desired.

Notes

This casserole pairs well with a green salad or roasted vegetables. Leftovers can be refrigerated for up to 3 days or frozen for up to 3 months.
