1. Preheat the Oven: Preheat your oven to 350°F (175°C).
2. Cook the Orzo: In a large pot, bring salted water to boil. Add orzo and cook according to package directions until al dente. Drain and set aside.
3. Sauté the Onions: In a large skillet, heat olive oil over medium heat. Add sliced onions and a pinch of salt. Sauté until they turn golden brown and caramelized, about 15-20 minutes.
4. Cook the Chicken: Season the chicken breasts with salt, pepper, and garlic powder. In the same skillet, add the chicken and cook until browned and no longer pink in the center, around 6-8 minutes per side. Remove from skillet and slice into bite-sized pieces.
5. Prepare the Sauce: In a mixing bowl, combine chicken broth, heavy cream, thyme, and adjust seasoning with salt and pepper.
6. Combine Ingredients: In a large mixing bowl, combine the cooked orzo, caramelized onions, sliced chicken, and the sauce. Mix thoroughly until well combined.
7. Transfer to Baking Dish: Pour the mixture into a greased 9×13-inch baking dish.
8. Add Cheese: Sprinkle shredded mozzarella and Gruyere cheese on top evenly.
9. Bake: Place in the preheated oven and bake for 30-35 minutes or until bubbly and golden on top.
10. Rest: Remove from the oven and allow to rest for about 10-15 minutes before serving to help it set.
