French Onion Chicken Orzo Casserole

Print Recipe

A cozy one-pan dish combining caramelized onions, tender shredded chicken, and orzo in a creamy, cheesy sauce.

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
  • 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 (reserve 1/2 cup for topping)
  • 1/2 cup grated Parmesan cheese
  • Optional: 1/2 teaspoon Worcestershire sauce or balsamic glaze

Instructions

  1. In a large oven-safe skillet or Dutch oven, melt the butter with the olive oil over medium heat. Add onions, sugar, and salt. Cook, stirring every few minutes, for 20–25 minutes until onions are deeply golden and jammy. Stir in minced garlic during the last 1–2 minutes.
  2. Stir the orzo into the onions and toast lightly for about 2 minutes. Add shredded chicken, dried thyme, and black pepper. If using, add Worcestershire sauce or balsamic glaze and mix.
  3. Pour in chicken broth and cream. Bring to a gentle simmer, cover, and cook for 8–10 minutes until orzo is tender and most liquid is absorbed.
  4. Stir in 1 cup mozzarella and Parmesan. Mix until melted and creamy. Adjust seasoning as needed.
  5. Preheat oven to 375°F (190°C). Sprinkle remaining mozzarella on top and bake uncovered for 10–15 minutes until bubbly and lightly golden.
  6. Let casserole rest for 5–10 minutes before serving. Garnish with fresh thyme or parsley if desired.

Notes

For less dairy, swap half the cream for extra broth. Use gluten-free orzo for a gluten-free option.
