What You’ll Need
Here’s what you’ll need to create this remarkable dish:
- 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 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)
Feel free to swap out the cream for a lighter option or use different herbs to customize it further!
Step-by-Step 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 about 20–25 minutes, stirring occasionally, until the onions are deeply golden and caramelized. Stir in the minced garlic during the last 1–2 minutes for an additional flavor punch.
- Add Orzo and Chicken: Stir in the orzo and cook for 2 minutes, allowing it to lightly toast. Mix in the shredded chicken, thyme, pepper, and Worcestershire sauce if desired.
- Pour in Liquids: Add the chicken broth and cream. Bring this mixture to a gentle simmer. Lower the heat, cover, and let it cook for about 8–10 minutes, stirring occasionally, until the orzo is tender.
- Add Cheese: Stir in 1 cup of mozzarella and the Parmesan cheese. Mix until everything is melted and creamy.
- Bake the Casserole: Preheat your 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.
- Serve: Let the casserole rest for 5–10 minutes before serving. Garnish with fresh thyme or parsley for a pop of color if desired.
Best Ways to Enjoy It
This casserole is absolutely delightful on its own, but you can elevate your meal with some creative serving ideas. Consider pairing it with a fresh green salad topped with a tangy vinaigrette, crusty garlic bread, or some roasted vegetables. For drinks, a chilled glass of white wine or sparkling water infused with lemon would complement the richness perfectly.
Keeping Leftovers Fresh
Storing leftovers is a breeze! Allow the casserole to cool completely before transferring it to an airtight container. It can be stored in the refrigerator for up to 3 days. For longer storage, freeze portions in freezer-safe containers for up to 2 months. Just remember to label with the date!
When you’re ready to enjoy your leftovers, reheat them in the oven at 350°F (175°C) or in the microwave until heated through. Ensure it reaches a safe temperature of 165°F before serving.
Pro Chef Tips
- Onion Care: Keep the heat moderate not to burn the onions; patience is key for that sweet caramelization.
- Extra Creaminess: Add a splash of extra cream or broth while reheating to bring back that creamy consistency.
- Make Ahead: Prepare everything up to the baking step, cover, and refrigerate it. Just pop it in the oven when you’re ready to bake!
Creative Twists
Feel free to switch things up! Try adding different proteins like beef or turkey, or make it vegetarian by incorporating roasted vegetables. You can also use whole-grain orzo for a healthier alternative, or add in some spinach or kale for a boost of greens!
