Step-by-Step Preparation for French Onion Chicken Orzo Casserole
Creating a French Onion Chicken Orzo Casserole is a fantastic way to bring warmth and comfort to your dining table. This one-dish wonder is perfect after a long day at work, and with these clear steps, you’ll have a delicious meal in no time!
Caramelize the Onions
Start by melting 2 tablespoons of unsalted butter and 1 tablespoon of olive oil in a large oven-safe skillet or Dutch oven over medium heat. Add 2 large thinly sliced yellow onions, along with 1 teaspoon of sugar and ½ teaspoon of salt. The sugar helps to draw out the natural sweetness, transforming the onions into a beautifully caramelized treat. Cook them for about 20–25 minutes, stirring occasionally, until they are a rich golden brown. Add 3 minced garlic cloves in the last minute of cooking for that perfect aromatic kick.

Add Orzo and Chicken
Once your onions are golden and fragrant, it’s time to stir in 1 ½ cups of orzo pasta. Let it toast for about 2 minutes — this enhances the flavor! Next, mix in 2 cups of cooked shredded chicken; rotisserie chicken works wonders here. To elevate the taste profile, add ½ teaspoon of dried thyme and ¼ teaspoon of black pepper, along with a splash of ½ teaspoon Worcestershire sauce if you’d like to enrich the depth of flavors. By combining these ingredients, your French Onion Chicken Orzo Casserole will truly shine.
Pour in the Liquids
Now, we’re moving on to the liquid gold! Pour in 2 cups of low-sodium chicken broth and 1 cup of heavy cream (or half and half for a lighter version). Bring everything to a gentle simmer, then reduce the heat to low, cover, and let it cook for 8–10 minutes. Stir occasionally until the orzo becomes tender and absorbs that creamy goodness.
Stir in the Cheese
Once everything is bubbling and fragrant, it’s time to stir in the cheesy goodness! Add 1 cup of shredded mozzarella cheese and ½ cup of grated Parmesan cheese. Mix until everything is melted and creamy. The key here is to reach that perfect gooey texture, where every bite oozes flavor.
Bake the Casserole
Preheat your oven to 375°F (190°C). Sprinkle the remaining ½ cup of mozzarella over the top of your orzo mixture, then pop it in the oven for 10–15 minutes. Keep an eye on it — you want it bubbly and golden brown on top. After baking, let it rest for 5–10 minutes before serving. This step is crucial; it allows the flavors to meld beautifully. Don’t forget to garnish with fresh thyme or parsley if you desire!
This French Onion Chicken Orzo Casserole is not only a delightful one-dish meal, but it also fills your kitchen with an inviting aroma that’s hard to resist. Enjoy!
