A comforting casserole that combines the rich flavors of French onion soup with tender orzo pasta, shredded chicken, and creamy cheeses.

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. Begin by caramelizing the onions. In your skillet or Dutch oven, melt the unsalted butter and olive oil over medium heat. Add the sliced onions, sugar, and salt. Allow them to cook for about 20–25 minutes, stirring occasionally until they become deeply golden and caramelized.
  2. Add the minced garlic in the last 1–2 minutes for an aromatic boost. Once the onions are ready, stir in the orzo and let it toast for about 2 minutes, enhancing its flavor.
  3. Incorporate the shredded chicken, dried thyme, black pepper, and Worcestershire sauce if you’re using it. Mix well.
  4. Pour in the chicken broth and heavy cream. Bring this mixture to a gentle simmer, reduce the heat, cover, and let cook for 8–10 minutes. Stir occasionally to ensure the orzo cooks evenly.
  5. After the orzo has become tender, stir in 1 cup of mozzarella cheese along with grated Parmesan. Preheat your oven to 375°F (190°C), then sprinkle the remaining mozzarella over the top.
  6. Bake the casserole uncovered for 10–15 minutes, or until it’s bubbly and golden. Let it rest for 5–10 minutes before serving to allow the flavors to meld beautifully.

Notes

Garnish with fresh herbs for added flavor and presentation. Store leftovers in an airtight container for up to 3–4 days.
