Step‑by‑Step Instructions for French Onion Chicken Orzo Casserole Step 1: Caramelize the Onions In a large oven-safe skillet, melt 2 tablespoons of unsalted butter with 1 tablespoon of olive oil over medium-low heat. Add 3 sliced yellow onions, sprinkle with 1 teaspoon of sugar and a pinch of salt. Cook slowly for 30-40 minutes, stirring frequently, until the onions are golden and caramelized. In the last minute, add 3 minced garlic cloves to enhance the aroma. Step 2: Cook the Chicken While the onions are caramelizing, prepare the chicken. In a separate skillet, heat a tablespoon of olive oil over medium heat. Season 2 cups of cooked shredded chicken with salt and black pepper. Add the chicken to the skillet and brown it for about 5-7 minutes on both sides until golden, but don’t cook it fully as it will bake in the casserole later. Step 3: Deglaze and Combine Once the onions are caramelized, carefully pour in 1 cup of low-sodium chicken broth to deglaze the skillet, scraping up any browned bits. Stir in 1 cup of orzo pasta, 1 cup of heavy cream, 1 teaspoon of dried thyme, and the browned chicken. Simmer the mixture over medium heat for 5-7 minutes until the orzo absorbs some of the liquid and is starting to soften. Step 4: Add Cheese and Bake Preheat your oven to 375°F (190°C). Stir in half of the 2 cups of shredded mozzarella into the orzo mixture, ensuring it melds into the creamy sauce. Transfer everything back into the same skillet, then top with the remaining mozzarella. Bake in the preheated oven for 20-25 minutes, or until the top is golden brown and bubbly. Step 5: Serve and Enjoy Once baked, let the French Onion Chicken Orzo Casserole rest for 5-10 minutes before serving to allow the flavors to meld. For an extra touch, garnish with fresh thyme or parsley if desired. This dish is perfect for family dinners or cozy gatherings, offering heartwarming flavors in every bite!

Expert Tips for French Onion Chicken Orzo Casserole • Perfectly Caramelized Onions: Cook the onions slowly over medium-low heat, stirring frequently. This ensures they caramelize beautifully without burning, enhancing the dish’s depth. • Proper Chicken Prep: Avoid fully cooking the chicken before adding it to the casserole. Browning is sufficient, as it will finish cooking in the oven, keeping it tender and juicy. • Creamy Consistency: Allow the orzo to simmer with the liquid for a few minutes before baking. This helps achieve that creamy texture by letting the pasta absorb the broth and cream. • Layering Cheese: Incorporate half the mozzarella into the mixture for creaminess, but reserve some for the top. This creates an irresistibly gooey crust that everyone will love. • Seasoning Checks: Taste the mixture before baking and adjust the salt and pepper to your preference. Remember, the flavors will concentrate while cooking, so season wisely. With these tips, your French Onion Chicken Orzo Casserole is sure to be a crowd-pleaser at your next meal! Make Ahead Options This French Onion Chicken Orzo Casserole is a fantastic meal prep option for busy home cooks! You can prepare the casserole up to 24 hours in advance by assembling it through the baking step, covering it tightly, and storing it in the refrigerator. To maintain the delicious creamy texture and prevent the orzo from absorbing too much liquid, refrigerate your casserole without baking until you’re ready to cook. When it’s time to enjoy, simply take it out, let it come to room temperature for about 30 minutes, then bake as instructed at 375°F (190°C) for 20-25 minutes until golden and bubbly. You’ll savor every bite knowing your weeknight meal was nearly ready to go! French Onion Chicken Orzo Casserole Recipe FAQs What type of onions work best for this casserole? I highly recommend using yellow onions for their sweet and rich flavor, which caramelizes beautifully. Avoid using red or white onions, as they might alter the taste and texture. How should I store leftover French Onion Chicken Orzo Casserole? Store any leftovers in an airtight container in the fridge for up to 3 days. Make sure the casserole has cooled completely before sealing to maintain freshness and prevent it from becoming soggy. Can I freeze this casserole? Absolutely! To freeze, let the casserole cool down completely. Then, wrap it tightly in plastic wrap and foil or place it in a freezer-safe container. It can last for up to 2 months.

If you find your orzo casserole is a bit dry, it might be due to over-baking or insufficient liquid during the cooking process. Next time, I recommend checking the orzo after about 20 minutes to ensure it’s soaking up enough broth. If you find it dry, you can add a splash of chicken broth or cream when reheating to bring back some moisture. Can I use different proteins or make this dish vegetarian? Yes!
