How to Make French Onion Chicken Orzo Casserole
-
Caramelize Onions: In a large oven-safe skillet, heat unsalted butter and olive oil over medium-low. Add sliced yellow onions, along with sugar and salt; cook while stirring often for 30-40 minutes until golden and caramelized. Stir in minced garlic and cook for an additional minute.
-
Cook Chicken: Season shredded chicken with salt and pepper; brown in a separate skillet on medium heat until lightly golden (it doesn’t need to be cooked through).
-
Deglaze and Combine: Pour low-sodium chicken broth into the caramelized onions, scraping the bottom of the skillet to incorporate all those tasty bits. Stir in orzo, heavy cream, dried thyme, and the browned chicken. Let it simmer for about 5-7 minutes until the orzo absorbs some liquid.

French Onion Chicken Orzo Casserole Recipe FAQs
What type of onions should I use for the best flavor?
I recommend using large yellow onions for their sweetness and depth of flavor, which are essential for that rich, caramelized taste in your French Onion Chicken Orzo Casserole. They become wonderfully soft and sweet when cooked slowly, making them the star of the dish.
How should I store leftovers of the casserole?
To store your French Onion Chicken Orzo Casserole, allow it to cool completely before transferring it to an airtight container. It can be stored in the fridge for up to 3 days. When you’re ready to enjoy it again, reheat in the oven at 350°F (175°C) until bubbling hot, adding a splash of cream if it seems dry to maintain that creamy texture.
Can I freeze the casserole for later?
Absolutely! To freeze, first let the casserole cool to room temperature. Then, portion it out into airtight containers or freezer bags, removing as much air as possible. It can last in the freezer for up to 2 months. When you’re ready to serve it, thaw overnight in the fridge and reheat in the oven until it’s hot and bubbly.
What if I don’t have rotisserie chicken? Can I still make this?
Certainly! If you don’t have rotisserie chicken, you can cook your own chicken. Simply season and sauté fresh chicken breasts or thighs in a bit of olive oil until golden but not fully cooked through. Chop them into pieces before adding to the casserole. This provides an equally delicious option.
Are there any alternative ingredients I can use for dietary restrictions?
Very much so! For a vegetarian option, swap the chicken for sautéed mushrooms and spinach. You can also use gluten-free orzo to accommodate gluten intolerance. If you’re looking for a lower-carb meal, try replacing orzo with cauliflower rice—it’s a delicious way to keep those comforting flavors while being mindful of dietary needs.
How long will it take for the orzo to cook while simmering?
When you simmer the orzo with the other ingredients, you want to keep an eye on it for about 5-7 minutes. It should absorb some liquid but remain al dente. This ensures it won’t become mushy once baked and will maintain a pleasing bite in your luscious casserole.
