Ingredients
Base Ingredients
- 2 tablespoons unsalted butter
- 1 tablespoon olive oil
- 2 large yellow onions, thinly sliced
- 1 teaspoon sugar
- ½ teaspoon salt
- 3 garlic cloves, minced
Main Components
- 1 ½ cups orzo pasta
- 2 cups cooked shredded chicken (rotisserie chicken works well)
- ½ teaspoon dried thyme
- ¼ teaspoon black pepper
Liquids & Cheese
- 2 cups low-sodium chicken broth
- 1 cup heavy cream or half and half for lighter option
- 1 ½ cups shredded mozzarella cheese, divided
- ½ cup grated Parmesan cheese
Optional
- ½ teaspoon Worcestershire sauce or balsamic glaze for added depth
Instructions
- 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 to release its flavor.
- Add Orzo and Chicken: Stir in the orzo pasta and cook for 2 minutes to lightly toast it. Then add the shredded chicken, dried thyme, black pepper, and Worcestershire sauce or balsamic glaze if using. Mix everything well to combine the flavors.
- Pour in Liquids: Pour in the chicken broth and heavy cream or half and half. Bring the mixture to a gentle simmer. Reduce the heat to low, cover the skillet, and let it cook for 8–10 minutes, stirring occasionally, until the orzo is tender and has absorbed most of the liquid.
- Add Cheese: Stir in 1 cup of shredded mozzarella and the grated Parmesan cheese until melted and creamy, creating a rich sauce that coats the orzo and chicken.
- Bake the Casserole: Preheat the oven to 375°F (190°C). Sprinkle the remaining ½ cup of mozzarella cheese evenly over the top of the casserole. Bake uncovered for 10–15 minutes until the cheese on top is bubbly and golden brown.
- Serve: Remove from the oven and let the casserole rest for 5–10 minutes before serving to allow it to set. Garnish with fresh thyme or parsley if desired for added color and flavor.
Notes
- For a lighter dish, use half and half instead of heavy cream.
- Rotisserie chicken is a quick shortcut, but you can use any cooked shredded chicken.
- Make sure to stir the orzo occasionally to prevent sticking while it cooks.
- Use an oven-safe skillet or transfer the mixture to a baking dish before baking if your skillet isn’t oven-proof.
- Adding Worcestershire sauce or balsamic glaze enhances depth, but it’s optional.
- Letting the casserole rest after baking helps it firm up and makes serving easier.
