  • Total Time: 35 minutes
  • Yield: 6 servings

Ingredients

Vegetables and Aromatics

  • 2 large yellow onions, thinly sliced
  • 3 garlic cloves, minced
  • 1 teaspoon sugar
  • 1/2 teaspoon salt

Dairy and Fats

  • 2 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 1 cup heavy cream (or half and half for lighter option)
  • 1 1/2 cups shredded mozzarella cheese
  • 1/2 cup grated Parmesan cheese

Protein and Grain

  • 2 cups cooked shredded chicken (rotisserie chicken works well)
  • 1 1/2 cups orzo pasta

Spices and Seasonings

  • 1/2 teaspoon dried thyme
  • 1/4 teaspoon black pepper
  • Optional: 1/2 teaspoon Worcestershire sauce or balsamic glaze for added depth

Liquids

  • 2 cups low-sodium chicken broth

Instructions

  1. Caramelize the Onions: 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 turn deeply golden and caramelized. During the last 1–2 minutes, stir in the minced garlic to release its aroma.
  2. Add Orzo and Chicken: Stir the orzo pasta into the caramelized onions and cook for 2 minutes to lightly toast it. Then add the shredded chicken, dried thyme, black pepper, and Worcestershire sauce or balsamic glaze if using. Mix thoroughly to combine all ingredients evenly.
  3. Pour in Liquids: Pour in the low-sodium chicken broth and heavy cream. Bring the mixture to a gentle simmer, then reduce the heat to low. Cover the skillet or pot and let it cook for 8–10 minutes, stirring occasionally, until the orzo is tender and has absorbed the flavors.
  4. Add Cheese: Stir in 1 cup of shredded mozzarella and all the grated Parmesan cheese. Mix until the cheeses melt completely and the sauce becomes creamy and smooth.
  5. Bake the Casserole: Preheat your oven to 375°F (190°C). Sprinkle the remaining 1/2 cup mozzarella cheese evenly over the top of the dish. Bake uncovered for 10–15 minutes, or until the casserole is bubbly and the cheese topping is golden and slightly crisp.
  6. Serve: Remove the casserole from the oven and let it rest for 5–10 minutes before serving. Garnish with fresh thyme or parsley if desired for a burst of color and freshness.

Notes

  • Using rotisserie chicken reduces prep time and adds flavor.
  • For a lighter dish, substitute heavy cream with half and half.
  • Worcestershire sauce or balsamic glaze is optional but adds complexity to the flavor.
  • Letting the casserole rest before serving helps it set for easier slicing and serving.
  • This dish can be prepared in an oven-safe skillet or Dutch oven for convenience.
