What You’ll Need
Gather These Simple 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
- 1/2 teaspoon dried thyme
- 1/4 teaspoon black pepper
- 2 cups low-sodium chicken broth
- 1 cup heavy cream
- 1 1/2 cups shredded mozzarella cheese
- 1/2 cup grated Parmesan cheese
- Optional: 1/2 teaspoon Worcestershire sauce or balsamic glaze
Let’s Make It Together
In a large oven-safe skillet or Dutch oven, melt the butter and olive oil over medium heat. Add the sliced onions, sugar, and salt. Cook for 20-25 minutes until the onions are beautifully caramelized, stirring occasionally. Stir in the minced garlic for the last 1-2 minutes to develop that lovely aroma.
Stir in the orzo and lightly toast for about 2 minutes. Add in the shredded chicken, dried thyme, and black pepper, mixing everything well, and incorporate Worcestershire sauce or balsamic glaze if desired for an extra depth of flavor.
Pour in the chicken broth and heavy cream, bringing the mixture to a simmer. Reduce the heat, cover, and cook for 8-10 minutes until the orzo is tender and has absorbed the delicious flavors.
Stir in 1 cup of mozzarella and the Parmesan cheese, mixing until they melt into a creamy, irresistible sauce.
Preheat your oven to 375°F (190°C). Sprinkle the remaining mozzarella on top and bake uncovered for 10-15 minutes until it’s bubbly and golden.
Allow the casserole to rest for 5-10 minutes before serving. For a lovely touch, garnish with fresh thyme or parsley if desired.
