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
• 1 1/2 cups shredded mozzarella cheese
• 1/2 cup grated Parmesan cheese
• Optional: 1/2 teaspoon Worcestershire sauce or balsamic glaze

Instructions

• Melt butter and olive oil in a large oven-safe skillet over medium heat. Add sliced onions, sugar, and salt. Cook for 20–25 minutes until the onions are deeply caramelized, adding garlic in the last 1–2 minutes.
• Stir in the orzo and cook for 2 minutes to lightly toast it. Add shredded chicken, thyme, pepper, and Worcestershire if using. Mix well.
• Pour in the chicken broth and cream. Bring to a gentle simmer, reduce heat to low, cover, and cook 8–10 minutes, stirring occasionally, until the orzo is tender.
• Stir in 1 cup mozzarella and the Parmesan cheese until melted and creamy.
• Preheat oven to 375°F (190°C). Sprinkle the remaining 1/2 cup mozzarella on top and bake uncovered for 10–15 minutes until bubbly and golden.
• Let the casserole rest for 5–10 minutes before serving.

Serving Tips

• Let the casserole rest for 5–10 minutes before serving so the sauce thickens and the flavors settle.
• Pair with a fresh green salad, roasted vegetables, or garlic bread for a complete meal.
• Garnish with fresh parsley or thyme for added color and freshness.
• Serve with a squeeze of lemon for a bright contrast to the creamy sauce.
• This dish is hearty enough to stand alone, making it perfect for potlucks or family dinners.

Storage Tips

• Refrigerate leftovers in an airtight container for up to 4 days.
• Reheat gently on the stove or in the microwave with a splash of broth or cream to restore creaminess.
• Freeze in freezer-safe containers for up to 2 months. Thaw overnight in the refrigerator before reheating.
• If freezing, avoid overbaking initially to keep the pasta from becoming mushy.
• For best results, bake leftovers covered to prevent drying.

FAQs

1. Can I use rice instead of orzo?
Yes, but increase the liquid and cooking time since rice takes longer to cook.

2. Can I use raw chicken instead of cooked?
Cooked shredded chicken is best, but you can use diced raw chicken—brown it before adding the orzo.

3. Can I make this casserole ahead of time?
Yes, assemble it up to the baking step, cover, and refrigerate for 24 hours. Bake when ready.

4. Can I substitute mozzarella?
Yes, use Gruyère, Swiss, provolone, or Monterey Jack.

5. Will this work without cream?
You can substitute with half and half or evaporated milk, but it won’t be as rich.

6. Can I make this gluten-free?
Use gluten-free orzo or small gluten-free pasta shapes and check broth labels.

7. Does it freeze well?
Yes, but slightly undercook the orzo so it stays firm after thawing.

8. How can I make it lighter?
Use half and half, reduce cheese, and add vegetables like spinach or broccoli.

9. What pan is best?
An oven-safe skillet or Dutch oven works perfectly for stovetop-to-oven cooking.

10. Can I double the recipe?
Absolutely—use a large casserole dish and increase bake time slightly.
