  • 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 (rotisserie works well)
  • 1/2 teaspoon dried thyme

Instructions

  1. Heat a large oven-safe skillet or Dutch oven over medium heat. Melt the butter with the olive oil.

  6. Pour in the chicken broth and cream, bringing to a gentle simmer.
  7. Reduce heat to low, cover, and cook for 8โ€“10 minutes until the orzo is tender, stirring occasionally.
  8. Stir in 1 cup of mozzarella and the Parmesan cheese until melted and creamy.
  9. Preheat the oven to 375ยฐF (190ยฐC). Sprinkle the remaining mozzarella over the top.
  10. Bake uncovered for 10โ€“15 minutes until the top is bubbly and light brown.
  11. Let the casserole rest for 5โ€“10 minutes before serving. Garnish with fresh thyme or parsley if desired.
