What You’ll Need
To whip up this delightful casserole, you’ll want to 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 (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)
Let’s Make It Together
1. Caramelize the Onions
In a large oven-safe skillet or Dutch oven, melt the butter and olive oil over medium heat. Add 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 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 oven to 375°F (190°C). Sprinkle the remaining 1/2 cup 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.
Delicious Variations to Try
Zesty Spinach & Artichoke: Toss in a cup of chopped spinach and a half-cup of artichoke hearts for a vibrant twist.
Mushroom Medley: Sauté some mushrooms with the onions for an earthy, umami-packed variation.
Creamy Pesto Orzo: Mix in a few tablespoons of your favorite pesto to add a fresh, basil-forward flavor to the dish.
Crunchy Toppings: For a bit of texture, sprinkle some crispy bread crumbs or crushed crackers on top before baking.
Chef Emma’s Helpful Tips
Make-Ahead Advice: Prepare the casserole up to the baking step and store it in the fridge covered. When you’re ready to bake, just add an extra 5–10 minutes to the cooking time.
Ingredient Swaps: Feel free to use leftover turkey or beef for a different protein twist. You could even swap the orzo for rice if you prefer.
Cutting Onions: To make slicing onions easier, refrigerate them for 30 minutes before cutting. Less tear, more deliciousness!
Storage Suggestions: Leftovers can be stored in an airtight container in the fridge for up to 4 days. Reheat gently in the microwave or in the oven until warmed through.
