French Onion Chicken Orzo Casserole


Description

A comforting casserole combining caramelized onions, tender chicken, creamy orzo, and a bubbling cheese topping.


Ingredients

Scale
  • 2 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 2 large yellow onions, thinly sliced
  • 1 teaspoon sugar
  • 1/2 teaspoon salt (plus more to taste)
  • 3 garlic cloves, minced
  • 1 1/2 cups dry 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 (or half-and-half)
  • 1 1/2 cups shredded mozzarella cheese, divided
  • 1/2 cup grated Parmesan cheese
  • Optional: 1/2 teaspoon Worcestershire sauce
  • Garnish: fresh thyme or parsley

Instructions

  1. In a large oven-safe skillet, melt the butter with olive oil over medium heat. Add sliced onions, sugar, and salt; cook for 20–25 minutes until deep golden.
  2. In the last minute, stir in minced garlic.
  3. Add orzo to the skillet and cook for 2 minutes to lightly toast.
  4. Mix in shredded chicken, thyme, black pepper, and Worcestershire sauce.
  5. Add broth and heavy cream, bringing to a simmer. Cover and cook for 8–10 minutes until orzo is tender.
  6. Stir in 1 cup of mozzarella and Parmesan until melted and creamy.
  7. Preheat oven to 375°F (190°C). Sprinkle remaining mozzarella on top and bake for 10–15 minutes until bubbly.
  8. Allow to rest for 5–10 minutes before serving, garnished with fresh herbs.

Notes

For a lighter version, substitute half-and-half for heavy cream. Make ahead and refrigerate before baking to save time.
