Ingredients
  

Casserole Base

  • 2 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 2 large yellow onions thinly sliced
  • 1 teaspoon sugar
  • 1/2 teaspoon salt
  • 3 cloves garlic 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
  • 1/2 teaspoon Worcestershire sauce or balsamic glaze for added depth

Instructions
 

Sauté the Onions

  • Heat the butter and olive oil in a large skillet over medium heat. Add the sliced onions and sugar, stirring occasionally. Cook until the onions are soft and golden brown, about 15-20 minutes.

Combine Flavors

  • Add the minced garlic and cook for an additional minute.

Mix in the Chicken and Orzo

  • Stir in the orzo pasta, shredded chicken, thyme, salt, and pepper. Ensure everything is well combined.

Add the Liquids

  • Pour in the chicken broth and heavy cream, stirring to combine. Bring the mixture to a gentle simmer.

Bake to Perfection

  • Transfer the mixture to a greased casserole dish. Top with mozzarella and Parmesan cheese, then cover with aluminum foil. Bake in a preheated oven at 375°F (190°C) for about 20-25 minutes. Remove the foil for the last 10 minutes.

Serve and Enjoy

  • Let the casserole cool for a few minutes before serving.
