Directions
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 the sliced onions, sugar, and salt. Cook for 20–25 minutes, stirring occasionally, until the onions turn deeply golden and caramelized. Stir in the minced garlic during the last 1–2 minutes to avoid burning.
-
Add Orzo and Chicken: Stir in the orzo and let it cook for about 2 minutes to lightly toast. Next, add the shredded chicken, thyme, pepper, and Worcestershire sauce if you’re using it. Mix everything well.
-
Pour in Liquids: Add the chicken broth and cream to the skillet. Bring it to a gentle simmer, then reduce the 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 cheese along with the Parmesan cheese. Mix until it’s melted and creamy, creating a luscious sauce.
-
Bake the Casserole: Preheat your oven to 375°F (190°C). Sprinkle the remaining 1/2 cup of mozzarella on top. Bake uncovered for 10–15 minutes, or until it’s bubbly and golden.
-
Serve: Allow it to rest for 5–10 minutes before serving. You can garnish it with some fresh thyme or parsley if desired for an extra pop of flavor.
How to serve French Onion Chicken Orzo Casserole
Best ways to enjoy it
This casserole pairs beautifully with a crisp green salad or some roasted vegetables. You can also serve it alongside crusty bread, perfect for soaking up any creamy goodness left on your plate. Feel free to drizzle a bit of balsamic glaze on top for an added touch of flavor!
How to store
Keeping leftovers fresh
Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, simply pop it in the oven or microwave until heated through. If you want to save it for later, it freezes well—just ensure you’ve let it cool completely before transferring to a freezer-safe container. It can last up to 3 months in the freezer, though it’s best enjoyed sooner for optimal flavor.
Tips to make
Pro chef tips
For a deeper flavor, consider adding a splash of white wine when caramelizing the onions or using a mix of cheeses like Gruyère for a more authentic French onion experience. If you’re short on time, pre-cooked rotisserie chicken is your best friend; it saves you time without skimping on flavor!
