Equipment

  • Large skillet
  • 9x13 inch baking dish
  • Large bowl
  • Oven
  • Aluminum foil
  • Measuring cups and spoons
  • Cutting board
  • Knife

Ingredients
  

  • 2 large yellow onions, thinly sliced
  • 2 tablespoons olive oil
  • 2 tablespoons butter
  • 1 teaspoon sugar
  • ½ teaspoon salt
  • ¼ teaspoon black pepper
  • 1.5 lbs boneless, skinless chicken breasts, cut into 1-inch cubes
  • 1 tablespoon olive oil
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • ½ teaspoon dried thyme
  • Salt and pepper to taste
  • 1 cup orzo pasta, uncooked
  • 4 cups chicken broth
  • 1 cup heavy cream
  • 1 ½ cups shredded Gruyère cheese, divided
  • ¼ cup grated Parmesan cheese
  • 2 tablespoons chopped fresh parsley
  • 1 tablespoon Worcestershire sauce
  • Salt and pepper to taste

Instructions
 

  • Preheat your oven to 375°F (190°C). Grease a 9x13 inch baking dish.
  • In a large skillet, heat olive oil and butter over medium heat. Add sliced onions, sugar, salt, and pepper.
  • Cook, stirring occasionally, for 30-40 minutes, or until the onions are deeply golden brown and caramelized. Remove from skillet and set aside.
  • In the same skillet, heat olive oil over medium-high heat. Add cubed chicken, garlic powder, onion powder, dried thyme, salt, and pepper.
  • Cook until chicken is cooked through and lightly browned, about 5-7 minutes. Remove from heat.
  • In a large bowl, combine uncooked orzo, chicken broth, heavy cream, 1/2 cup Gruyère cheese, Parmesan cheese, parsley, Worcestershire sauce, salt, and pepper. Stir well.
  • Pour the orzo mixture into the prepared baking dish.
  • Top with the cooked chicken and caramelized onions, spreading them evenly over the orzo.
  • Sprinkle generously with the remaining Gruyère cheese.
  • Cover the baking dish with aluminum foil and bake for 30 minutes.
  • Remove the foil and bake for an additional 15-20 minutes, or until the orzo is tender and the cheese is melted and bubbly.
  • Let the bake rest for 10 minutes before serving.

Notes

For an extra layer of flavor, deglaze the skillet with a splash of dry white wine (like Sauvignon Blanc or Pinot Grigio) after caramelizing the onions. Let the wine reduce slightly before adding the onions back to the skillet. You can assemble the entire bake ahead of time and store it in the refrigerator for up to 24 hours. When ready to bake, add an extra 10-15 minutes to the baking time to ensure it's heated through. Gruyère is the ideal cheese, but Swiss or Provolone can be substituted. Omit the chicken for a vegetarian option, substituting with mushrooms or other vegetables.
