Ingredients:

  • 2 tablespoons olive oil
  • 2 large yellow onions, thinly sliced
  • 1 teaspoon sugar
  • 4 boneless, skinless chicken breasts, cut into bite-sized pieces
  • 1 teaspoon salt, plus more to taste
  • 1/2 teaspoon black pepper, plus more to taste
  • 1 tablespoon all-purpose flour
  • 1 cup chicken broth
  • 1/2 cup heavy cream
  • 1 teaspoon Worcestershire sauce
  • 1 teaspoon dried thyme
  • 1 1/2 cups uncooked orzo pasta
  • 1 1/2 cups shredded Gruyere cheese, divided
  • 1/2 cup grated Parmesan cheese
  • 1/4 cup panko breadcrum extractbs
  • 2 tablespoons unsalted butter, melted

    • Cooking Instructions:

    The magic of this casserole truly begin extracts with the onions. Taking the time to properly caramelize them will unlock a depth of flavor that is simply unparalleled. Don’t rush this step; low and slow is the name of the game here.

    Caramelizing the Onions

  • Heat the olive oil in a large, oven-safe skillet or Dutch oven over medium heat. Add the thinly sliced yellow onions and the teaspoon of sugar. Stir to coat the onions. Cook, stirring occasionally, for 25-35 minutes, or until the onions are deeply golden brown and softened. This process is crucial for developing that classic French onion soup flavor. If they start to stick, you can add a tablespoon of water or chicken broth to the pan. Reduce the heat to low if they begin extract to brown too quickly. Once caramelized, remove the onions from the skillet and set them aside in a bowl.

    • Cooking the Chicken and Building the Sauce

  • Add the bite-sized chicken pieces to the same skillet (no need to wipe it clean). Season the chicken with 1 teaspoon of salt and 1/2 teaspoon of black pepper. Cook over medium-high heat, stirring occasionally, until the chicken is browned on all sides and cooked through, about 5-7 minutes. Remove the cooked chicken from the skillet and add it to the bowl with the caramelized onions.
  • Reduce the heat to medium. Sprinkle the tablespoon of all-purpose flour over the remaining drippings in the skillet. Whisk constantly for about 1 minute to cook out the raw flour taste and form a roux. Gradually whisk in the 1 cup of chicken broth, scraping up any browned bits from the bottom of the skillet. Bring the mixture to a simmer, whisking until it begin extracts to thicken.
  • Stir in the 1/2 cup of heavy cream, Worcestershire sauce, and dried thyme. Continue to cook, stirring, until the sauce is smooth and has thickened further, about 2-3 minutes. This forms the luscious base for our casserole.

    • Combining and Baking the Casserole

  • Add the uncooked orzo pasta directly into the simmering sauce. Stir well to ensure the orzo is fully submerged. Bring the mixture back to a gentle simmer and cook for about 5 minutes, stirring frequently, until the orzo is partially cooked. It will continue to cook in the oven. Stir in 1 cup of the shredded Gruyere cheese and the grated Parmesan cheese until melted and well combined.
  • Gently fold in the reserved caramelized onions and cooked chicken. Taste the mixture and adjust seasoning with additional salt and pepper if needed. If the mixture seems too thick, you can add a splash more chicken broth or water.
  • Preheat your oven to 375°F (190°C). In a small bowl, combine the panko breadcrum extractbs and the melted butter. Stir until the breadcrum extractbs are evenly coated. Sprinkle the remaining 1/2 cup of Gruyere cheese evenly over the top of the casserole in the skillet. Then, sprinkle the buttered panko breadcrum extractbs over the cheese layer, creating a delightful crunchy topping.
  • Place the skillet in the preheated oven and bake for 20-25 minutes, or until the casserole is bubbly around the edges and the topping is golden brown and crisp. Let the casserole rest for about 5-10 minutes before serving to allow it to set slightly. This is a great time to reheat any side dishes or set the table. Enjoy the incredible aroma that fills your kitchen!

    Frequently Asked Questions:

    Can I make this ahead of time?

    Yes, you can absolutely prepare this casserole ahead of time! Assemble all the ingredients as directed, cover it tightly, and refrigerate for up to 24 hours. When you’re ready to bake, you may need to add an extra 5-10 minutes to the baking time, as it will be starting from cold. You might also want to let it sit at room temperature for about 30 minutes before baking to ensure even cooking.

    What kind of chicken should I use?

    This recipe works wonderfully with both boneless, skinless chicken breasts or thighs. If you prefer a richer flavor, chicken thighs are an excellent choice. For convenience, you can also use pre-cooked rotisserie chicken. Just shred it and add it in during the last few minutes of the stovetop cooking stage, allowing it to heat through before transferring to the oven.

    Is it very onion-heavy?

    The recipe uses a generous amount of onions, but they are caramelized and softened during the cooking process, which mellows their sharpness and brings out their natural sweetness. The resulting flavor is deeply savory and complex, forming the signature essence of French onion soup, rather than an overpowering raw onion taste.
