Step-by-step instructions
-
Caramelize the Onions: In a large oven-safe skillet or Dutch oven, melt the butter and olive oil over medium heat. Add sliced onions, sugar, and salt. Cook for 20-25 minutes, stirring occasionally, until the onions are deeply golden and caramelized. Stir in the minced garlic during the last 1-2 minutes.
-
Add Orzo and Chicken: Stir in the orzo and cook for 2 minutes, allowing it to lightly toast. Add the shredded chicken, thyme, pepper, and Worcestershire sauce if using. Mix well.
-
Pour in Liquids: Add the chicken broth and cream. Bring to a gentle simmer. Reduce heat to low, cover, and let it cook for 8-10 minutes, stirring occasionally, until the orzo is tender.
-
Add Cheese: Stir in 1 cup of mozzarella and the Parmesan cheese. Mix until melted and creamy.
-
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.
-
Serve: Let it rest for 5-10 minutes before serving. Garnish with fresh thyme or parsley if desired.
Best ways to enjoy it
To make your meal even more special, consider serving this casserole with a crisp green salad drizzled with a light vinaigrette. A side of garlic bread can soak up any extra creamy sauce, making for a complete comfort food experience. If you want to enhance the flavors even more, a glass of white wine pairs beautifully with this dish!
Keeping leftovers fresh
Storing this casserole is straightforward. Allow it to cool completely, then transfer it to an airtight container and refrigerate. It will last about 3-4 days in the refrigerator. To reheat, simply pop it in the oven or microwave until heated through. If you plan to freeze it, layer it in a freezer-safe container, leaving some space for expansion; it should hold up for about 2-3 months!
Helpful cooking tips
To make this dish even tastier, don’t rush the caramelization of the onions; patience is key for unlocking that deep brown flavor. Also, taste as you go! Adjust the seasonings based on your preference—maybe a little extra thyme or even some red pepper flakes for a kick.
Creative twists
There are endless variations to this casserole. You can easily swap out the chicken for turkey or even add spinach or mushrooms for an extra nutritional boost. Cheese lovers might indulge in Gruyère instead of mozzarella for a more authentic French onion taste. For a lighter option, use a mix of Greek yogurt and broth in place of the heavy cream.

This casserole takes about 15 minutes of prep and approximately 45 minutes from start to finish, including baking.
