A creamy casserole that blends the rich flavors of French onion soup with tender chicken and orzo pasta.

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
  • 2 cups cooked shredded chicken (rotisserie works wonderfully)
  • 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
  • 1/2 cup grated Parmesan cheese
  • Optional: 1/2 teaspoon Worcestershire sauce or balsamic glaze

Instructions

  1. Melt the butter and olive oil in a large oven-safe skillet or Dutch oven over medium heat.
  2. Add the sliced onions, sugar, and salt; cook for 20–25 minutes until caramelized. Add minced garlic in the last 1–2 minutes.
  3. Stir in the orzo and toast for 2 minutes.
  4. Add shredded chicken, thyme, and pepper (and Worcestershire sauce if using); mix well.
  5. Pour in chicken broth and cream; bring to a gentle simmer 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 uncovered for 10–15 minutes until bubbly and golden.
  8. Let it rest for 5–10 minutes before serving.

Notes

For deeper flavor, use high-quality chicken broth. Rotisserie chicken enhances the flavor profile.
