A comforting casserole combining the flavors of French onion soup with orzo and juicy chicken, topped with melted cheese.

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
  • 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. In a large oven-safe skillet or Dutch oven, 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 deeply golden and caramelized. Stir in the minced garlic during the last 1-2 minutes.
  2. Stir in the orzo and toast it for 2 minutes. Then, add the shredded chicken, thyme, pepper, and Worcestershire sauce if using. Mix well.
  3. Add the chicken broth and cream, bringing it to a gentle simmer. Reduce heat to low, cover, and let it cook for 8-10 minutes, stirring occasionally until the orzo is tender.
  4. Stir in 1 cup of mozzarella and the Parmesan cheese. Mix until melted and creamy.
  5. Preheat oven to 375°F (190°C). Sprinkle the remaining 1/2 cup mozzarella over the top. Bake uncovered for 10-15 minutes until bubbly and golden on top.
  6. Allow it to rest for 5-10 minutes before serving. Garnish with fresh thyme or parsley if desired.

Notes

Consider using chicken thighs for a juicier texture. Feel free to add sautéed mushrooms or different cheeses for variety.
