• 1 1/2 cups orzo pasta
• 2 cups cooked shredded chicken (rotisserie works well)

4. Add Cheese: Stir in 1 cup mozzarella and the Parmesan cheese. Mix until melted and creamy.
5. Bake the Casserole: Preheat oven to 375°F (190°C). Sprinkle the remaining 1/2 cup mozzarella over the top. Bake uncovered for 10–15 minutes until bubbly and golden on top.

Notes

• Caramelizing the onions is key. Take your time with this step. Slow cooking the onions brings out their natural sweetness and gives the dish its signature French onion flavor.
• Adjust the cream for a lighter option. You can substitute half-and-half for heavy cream if you prefer a lighter casserole while still keeping it creamy.
