How to Make French Onion Chicken Orzo Casserole

Making the French Onion Chicken Orzo Casserole is quite straightforward. Follow these detailed steps to ensure it turns out delicious every single time.

Ingredients

To make this amazing casserole, you will need the following ingredients:

  • 2 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 2 large yellow onions (thinly sliced)
  • 1 teaspoon sugar
  • 1/2 teaspoon salt
  • 3 garlic cloves (minced)
  • 1 1/2 cups orzo pasta
  • 2 cups cooked shredded chicken (rotisserie works well)
  • 1/2 teaspoon dried thyme
  • 1/4 teaspoon black pepper
  • 2 cups low-sodium chicken broth
  • 1 cup heavy cream (or half and half for a lighter option)
  • 1 1/2 cups shredded mozzarella cheese
  • 1/2 cup grated Parmesan cheese
  • Optional: 1/2 teaspoon Worcestershire sauce or balsamic glaze (for added depth)

Directions

Caramelize the Onions

Start by caramelizing the onions. In a large oven-safe skillet or Dutch oven, melt the butter and olive oil over medium heat. Then, add the sliced onions, sugar, and salt. Cook this mixture for 20–25 minutes, stirring occasionally. You want the onions to become deeply golden and caramelized. Toward the last 1-2 minutes of cooking, stir in the minced garlic. This extra step adds a wonderful aroma to your dish.

Add Orzo and Chicken

Once the onions are caramelized, it’s time to add the orzo and chicken. Stir in the orzo and allow it to cook for 2 minutes to lightly toast the pasta. After that, add the shredded chicken, dried thyme, pepper, and Worcestershire sauce if you choose to use it. Mix everything well to ensure the chicken and orzo are evenly distributed among the onions.

Pour in Liquids

Now, it’s time to add the liquids. Pour in the low-sodium chicken broth and heavy cream. Bring the mixture to a gentle simmer. After it simmers, reduce the heat to low, cover the skillet, and let it cook for 8–10 minutes. Stir occasionally to prevent the orzo from sticking and to ensure it becomes tender.

Add Cheese

Once the orzo is tender, stir in 1 cup of mozzarella cheese and the grated Parmesan cheese. Mix everything until the cheese has melted and the mixture is creamy.

Bake the Casserole

Before baking, preheat your oven to 375°F (190°C). Sprinkle the remaining 1/2 cup of mozzarella cheese over the top of your casserole. Bake uncovered for 10–15 minutes, or until it becomes bubbly and golden on top. This step gives the casserole a nice texture and enhances the flavor.

Serve

Let the casserole rest for about 5–10 minutes before serving. This brief wait allows the flavors to settle and makes it easier to serve. If desired, garnish with fresh thyme or parsley to add a touch of color and freshness to your meal.

How to Serve French Onion Chicken Orzo Casserole

Serving the French Onion Chicken Orzo Casserole is simple. You can place the casserole dish in the center of the table, allowing everyone to help themselves. It goes well with a side salad or garlic bread.

Feel free to drizzle some balsamic glaze or Worcestershire sauce on top for an extra touch of flavor. Pair this delicious meal with a glass of white wine or your favorite soft drink for a delightful dining experience. Don’t forget to sprinkle a little extra cheese on top when serving if you want an even cheesier treat!

How to Store French Onion Chicken Orzo Casserole

If you have leftovers, storing the French Onion Chicken Orzo Casserole is quite easy. Allow it to cool completely at room temperature before covering it with a lid or transferring it to an airtight container. Store the casserole in the refrigerator, where it will last for about 3 to 4 days.

If you want to store it for a more extended period, consider freezing it. Portion the casserole into individual servings, wrap them in plastic wrap, and then place them in a freezer-safe container. When stored properly, it can last in the freezer for about 2 to 3 months. To reheat, thaw in the refrigerator overnight and bake in the oven until warmed through.

Tips to Make French Onion Chicken Orzo Casserole

Here are some tips to enhance your cooking experience and ensure your dish turns out perfectly every time:

  1. Use Good Quality Cheese: The flavor of the cheese is essential in this casserole. Opt for fresh mozzarella and Parmesan for the best results.

  2. Caramelize the Onions Slowly: Take your time while caramelizing the onions. Cooking them on low heat allows for better flavor and sweetness.

  3. Customize Your Chicken: You can use leftover chicken from previous meals or a store-bought rotisserie chicken to save time. This makes preparation quick and easy.

  4. Aim for Fresh Ingredients: Whenever possible, use fresh thyme and garlic. The difference in flavor is substantial compared to dried versions.

  5. Play With Toppings: Experiment with different toppings like breadcrumbs or herbs before baking for added texture.

Variation

If you want to switch it up a bit, consider adding different vegetables to your casserole. Spinach, mushrooms, or even grated carrots would blend beautifully with the rest of the ingredients. You can also substitute the orzo for another type of pasta like quinoa or farro for a different texture.

For a vegetarian option, you can simply omit the chicken and replace it with sautéed vegetables. This makes it a delightful meat-free alternative that retains all its savory flavors.

FAQs

Can I make French Onion Chicken Orzo Casserole ahead of time?

Yes, you can prepare the casserole ahead of time. Assemble the dish, but don’t bake it. Cover it tightly with plastic wrap and store it in the refrigerator. When you’re ready to bake, simply remove it from the fridge and follow the baking instructions.

Can I use other types of pasta instead of orzo?

Yes! While orzo works wonderfully in this recipe, you can use other small pasta types like ditalini or even small shells. Just adjust the cooking time accordingly, as different pasta may require different cook times.

What can I use instead of heavy cream?

If you prefer a lighter option, you can use half and half instead of heavy cream. You can also substitute it with a combination of low-fat milk and Greek yogurt to make it even healthier without losing creaminess.

With this guide, you can prepare the French Onion Chicken Orzo Casserole with ease. Enjoy the delicious result and the time spent with loved ones. Happy cooking!
