French Onion Chicken Orzo Casserole


Description

A comforting casserole featuring tender orzo, savory chicken, and deeply caramelized onions, topped with melted cheese.


Ingredients

Scale
  • 2 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 2 large yellow onions, thinly sliced (about 300 g)
  • 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 (about 170 g total)
  • 1/2 cup grated Parmesan cheese (about 50 g)
  • Optional: 1/2 teaspoon Worcestershire sauce or a drizzle of balsamic glaze
  • Fresh thyme or parsley for garnish (optional)

Instructions

  1. Preheat your oven to 375°F (190°C). Have an oven-safe skillet or Dutch oven ready.
  2. In the skillet or Dutch oven over medium heat, melt butter and olive oil. Add onions, sugar, and salt. Caramelize for 20-25 minutes until golden. Stir in garlic during the last 1-2 minutes.
  3. Stir in orzo and cook for 2 minutes. Add shredded chicken, thyme, black pepper, and Worcestershire sauce if using. Mix well.
  4. Add chicken broth and cream. Bring to simmer, reduce heat, cover, and cook for 8-10 minutes until orzo is tender and liquid is mostly absorbed.
  5. Stir in 1 cup of mozzarella and Parmesan until melted. Sprinkle remaining mozzarella on top. Bake 10-15 minutes until bubbly and golden.
  6. Let rest for 5-10 minutes before serving. Garnish with fresh thyme or parsley if desired.

Notes

For a lighter version, use half-and-half instead of heavy cream. This dish freezes well; portion and freeze for up to 2-3 months.
