Caramelize the Onions
  1. Melt the butter and olive oil in a large oven-safe skillet or Dutch oven over medium heat.
  2. Add the sliced onions, sugar, and salt to the skillet.
  3. Cook the onions for 20-25 minutes, stirring occasionally, until they are deeply golden and caramelized.

  2. Mix in the shredded chicken, thyme, black pepper, and Worcestershire sauce (if using).
Pour in Liquids

  2. Once simmering, reduce heat to low, cover the skillet, and let it cook for 8-10 minutes.
  3. Stir occasionally until orzo is tender.
Add Cheese
  1. Stir in 1 cup of shredded mozzarella and grated Parmesan cheese until melted and creamy.
Bake the Casserole

Notes

For best results, use yellow onions and allow them to caramelize slowly. Feel free to experiment with other cheeses or add vegetables for a vegetarian option.
