Ingredients
- 2 cups orzo pasta
- 2 tablespoons olive oil
- 1 large onion, sliced
- 2 cups cooked chicken, shredded
- 2 cups chicken broth
- 1 cup heavy cream
- 1 cup shredded cheese (such as Gruyère or Swiss)
- Salt and pepper to taste
- Fresh thyme for garnish
How to Make It
Preheat the oven: Preheat oven to 350°F (175°C).
Caramelize the onions: In a large skillet, heat olive oil over medium heat. Add sliced onions and cook until caramelized, about 20 minutes. Stir the onions occasionally so they cook evenly and do not brown too quickly.
Combine the casserole ingredients: In a large bowl, combine cooked orzo, shredded chicken, chicken broth, heavy cream, and caramelized onions. Season with salt and pepper. Stir until the ingredients are evenly distributed.
Transfer and top with cheese: Transfer the mixture to a baking dish and top with shredded cheese. Spread the cheese evenly across the surface for a golden, bubbly topping.
Bake: Bake in the preheated oven for 25-30 minutes or until the cheese is melted and bubbly.
Garnish and serve: Garnish with fresh thyme before serving.
How to Serve It
- Serve the casserole with a crisp green salad dressed with a light vinaigrette.
- Pair it with steamed green beans, roasted broccoli, or another green vegetable.
- Add extra fresh thyme on top just before serving for a bright, herby finish.
How to Store It
Let leftovers cool before transferring them to an airtight container. Store the casserole in the refrigerator.
For longer storage, place cooled portions in freezer-safe containers and freeze. Thaw frozen leftovers in the refrigerator before reheating.
Reheat refrigerated or thawed portions in the oven until warmed through. Covering the dish while reheating can help prevent the casserole from drying out. Individual portions can also be reheated gently until hot.
Helpful Tips
- Give the onions time to caramelize: Cooking them for about 20 minutes develops the sweet, rich flavor that defines this casserole.
- Use evenly shredded chicken: Smaller pieces distribute more consistently throughout the orzo mixture.
- Spread the cheese evenly: A uniform layer helps the topping melt and brown consistently during baking.
Optional Variations
- Use Gruyère for a nutty, luxurious flavor or Swiss cheese for a slightly milder topping.
- Add sliced mushrooms with the onions for extra savory depth.
- Stir in chopped fresh herbs along with the thyme garnish for a brighter finish.

You can assemble the mixture in the baking dish ahead of baking. Keep it refrigerated until ready to bake, then bake until the cheese is melted and bubbly.
