Step-by-Step Instructions for French Onion Chicken Orzo Casserole
  1. Melt the butter and olive oil in a large oven-safe skillet over medium-low heat. Add the onions, sugar, and salt, and cook slowly for 30-40 minutes until caramelized.
  2. In a separate skillet, season the cooked shredded chicken with salt and pepper and cook until lightly browned, about 5-7 minutes.
  3. Deglaze the skillet with chicken broth, scraping up browned bits. Stir in orzo, cream, thyme, and chicken. Simmer for 5-7 minutes.
  4. Preheat oven to 375°F. Mix half of the mozzarella into the orzo mixture and pour into a baking dish. Top with remaining mozzarella and bake for 20-25 minutes.
  5. Let the casserole rest for 5-10 minutes, then garnish and serve.
