How to Make French Onion Chicken Orzo Casserole

Begin by creating the luscious base that will set the stage for your French Onion Chicken Orzo Casserole. In a large, heavy skillet or a Dutch oven, melt two tablespoons of unsalted butter together with one tablespoon of olive oil over medium heat. The moment the butter begins to bubble and froth, add two large yellow onions, sliced thinly. Sprinkle in one teaspoon of sugar and a half teaspoon of salt to coax out their natural sweetness. Stir occasionally for twenty to twenty-five minutes as the onions transform into a deep, golden hue, their aroma filling the kitchen with warmth and comfort.

As the onions near completion, the rich scent of caramelization will tease your senses. Just when they appear perfect, add three minced garlic cloves and sauté for another one to two minutes until fragrant. With the foundation established, it’s time to introduce one and a half cups of orzo pasta into your skillet, allowing it to toast lightly for just two minutes. This step adds a lovely nutty flavor that’ll elevate the entire dish. Stir in two cups of cooked, shredded chicken—rotisserie chicken works beautifully—along with a half teaspoon of dried thyme and a quarter teaspoon of black pepper, mixing until everything is well combined.

Pour in two cups of low-sodium chicken broth and one cup of heavy cream, allowing the mixture to bubble gently. Lower the heat, cover, and let it simmer for eight to ten minutes, stirring occasionally until the orzo is perfectly tender and creamy. You’ll watch as the broth and cream meld together, creating a rich sauce that clings to the orzo.

Now, it’s time to take this comfort food to the next level. Stir in one cup of shredded mozzarella cheese and a half cup of grated Parmesan cheese, mixing until everything is melted and creamy, enveloping the ingredients in a blanket of deliciousness.

Preheat your oven to three hundred seventy-five degrees Fahrenheit. Transfer the mixture to an oven-safe dish for baking, ensuring the cheese blends throughout. Sprinkle the remaining half cup of mozzarella generously over the top for an ultimate cheesy finish. Bake uncovered for ten to fifteen minutes, keeping an eye out for that beautiful golden crust forming. The sound of bubbling cheese will be music to your ears, a hint of what’s to come.

Finally, allow it to rest for five to ten minutes. This pause enables the flavors to settle and develop further. Garnish with fresh thyme or parsley for a pop of color and herbaceous brightness in your completed dish.

Now that your kitchen smells amazing, let’s look at what you’ll need.

Two tablespoons of unsalted butter, one tablespoon of olive oil, two large yellow onions thinly sliced, one teaspoon of sugar, one half teaspoon of salt, three garlic cloves minced, one and a half cups of orzo pasta, two cups of cooked shredded chicken rotisserie works well, one half teaspoon of dried thyme, one quarter teaspoon of black pepper, two cups of low-sodium chicken broth, one cup of heavy cream or half and half for a lighter option, one and a half cups of shredded mozzarella cheese, one half cup of grated Parmesan cheese, and optionally one half teaspoon of Worcestershire sauce or balsamic glaze for added depth.

Always use fresh ingredients for the best flavor, and don’t hesitate to substitute ingredients according to your preferences while maintaining balance.

Caramelize the Onions

In a large oven-safe skillet or Dutch oven, melt the butter with the olive oil over medium heat. Add the sliced onions, sugar, and salt. Cook for twenty to twenty-five minutes, stirring occasionally, until the onions are deeply golden and caramelized. Stir in the minced garlic during the last one to two minutes.

Add Orzo and Chicken

Stir in the orzo and cook for two minutes, allowing it to lightly toast. Add 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 eight to ten minutes, stirring occasionally, until the orzo is tender.

Add Cheese

Stir in one cup of mozzarella and the Parmesan cheese. Mix until melted and creamy.

Bake the Casserole

Preheat the oven to three hundred seventy-five degrees Fahrenheit. Sprinkle the remaining half cup of mozzarella over the top. Bake uncovered for ten to fifteen minutes until bubbly and golden on top.

Serve

Let it rest for five to ten minutes before serving. Garnish with fresh thyme or parsley if desired.

If you encounter any challenges during preparation, a great troubleshooting tip is to keep the heat low when simmering to prevent sticking, and make sure not to overlook the baking, as it should only take a brief time to achieve that dreamy, golden crust.
