French Onion Chicken Orzo Casserole

A comforting casserole that blends caramelized onions, shredded chicken, and creamy orzo pasta, perfect for family gatherings.

  • Total Time: 60 minutes
  • Yield: 6 servings 1x

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
  • 1/2 teaspoon Worcestershire sauce or balsamic glaze (optional)

Instructions

  1. Melt the butter and olive oil in a large oven-safe skillet or Dutch oven over medium heat. Add 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 cook for 2 minutes, allowing it to lightly toast. Add shredded chicken, thyme, pepper, and Worcestershire if using. Mix well.
  3. Add the chicken broth and cream, bringing to a gentle simmer. Reduce heat to low, cover, and 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 the 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. Let it rest for 5–10 minutes before serving. Garnish with fresh thyme or parsley if desired.

Notes

Ensure even caramelization of onions by slicing them thinly and cooking them low and slow.
