Gather these simple ingredients to get started:

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 (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
Optional: 1/2 teaspoon Worcestershire sauce or balsamic glaze for added depth

Step-by-Step Instructions

1. Caramelize the Onions

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, stirring occasionally, until the onions are deeply golden and caramelized. Stir in the minced garlic during the last 1-2 minutes.

2. Add Orzo and Chicken

Stir in the orzo and cook for 2 minutes, allowing it to lightly toast. Add the shredded chicken, thyme, pepper, and Worcestershire sauce if using. Mix well.

3. Pour in Liquids

Add the chicken broth and cream. Bring to a gentle simmer. Reduce heat to low, cover, and let it cook for 8-10 minutes, stirring occasionally, until the orzo is tender.

4. Add Cheese

Stir in 1 cup of mozzarella and the Parmesan cheese. Mix until melted and creamy.

5. Bake the Casserole

Preheat the oven to 375°F (190°C). Sprinkle the remaining 1/2 cup of mozzarella over the top. Bake uncovered for 10-15 minutes until bubbly and golden on top.

6. Serve

Let it rest for 5-10 minutes before serving. Garnish with fresh thyme or parsley if desired.

Fun Ways to Customize It
