Ingredients
  

For the caramelized onions
  • 2 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 2 large yellow onions, thinly sliced
  • 1 teaspoon granulated sugar
  • 1/2 teaspoon salt
  • 5 cloves garlic, minced
For the main dish
  • 1 1/2 cups dry orzo pasta
  • 2 cups cooked, shredded chicken
  • 1/2 teaspoon dried thyme
  • 1/4 teaspoon ground black pepper
  • 2 cups low-sodium chicken broth
  • 1 cup heavy cream or half-and-half
  • 1 cup shredded Gruyère-style cheese
  • 1 cup shredded mozzarella cheese, divided
  • 1/2 cup grated Parmesan cheese
  • Optional garnish: chopped fresh parsley or thyme

Method
 

Preparation
  1. In a large oven-safe skillet or Dutch oven, melt the butter and olive oil over medium heat.
  2. Add the sliced onions, sugar, and salt. Let them cook slowly for about 20 to 25 minutes until caramelized.
  3. Two minutes before caramelization is complete, add the minced garlic.
  4. Stir in the dry orzo and onion powder, toasting for about 2 minutes.
  5. Mix in the shredded chicken, thyme, and black pepper, combining well.
  6. Pour in the chicken broth and cream, bring to a gentle simmer, covering and cooking for 8 to 10 minutes.
  7. Stir in the Gruyère cheese, Parmesan, and half of the mozzarella until melted.
  8. Preheat the oven to 375°F. Sprinkle the remaining mozzarella on top.
  9. Transfer the skillet to the oven and bake uncovered for 10 to 15 minutes until bubbly.
  10. Let it rest for 5 to 10 minutes before serving, optionally garnished with fresh herbs.
