Description

A comforting casserole with creamy orzo, caramelized onions, shredded chicken, and a melty 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
  • 3 garlic cloves, minced
  • 1 1/2 cups orzo pasta (dry)
  • 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 (or half-and-half for a lighter option)
  • 1 1/2 cups shredded mozzarella cheese (divided)
  • 1/2 cup grated Parmesan cheese
  • Optional: 1/2 teaspoon Worcestershire sauce or splash of balsamic glaze

Instructions

  1. Preheat the oven to 375°F (190°C).
  2. In a large oven-safe skillet, melt butter and olive oil over medium heat. Add onions, sugar, and salt. Cook for 20–25 minutes until caramelized. Stir in garlic for the last 1–2 minutes.
  3. Add dry orzo and lightly toast for 1–2 minutes.
  4. Stir in shredded chicken, thyme, and black pepper. Add Worcestershire sauce or balsamic if using.
  5. Pour in chicken broth and heavy cream. Bring to a simmer, cover, and cook for 8–10 minutes until orzo is tender.
  6. Mix in 1 cup of mozzarella and Parmesan until melted.
  7. Transfer to a baking dish if necessary, sprinkle remaining mozzarella on top, and bake for 10–15 minutes until bubbly and golden.
  8. Let rest for 5–10 minutes before serving. Garnish with fresh herbs if desired.

Notes

Use rotisserie chicken for convenience. For a gluten-free option, substitute orzo with a gluten-free product.
