Gather These Items

• 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)

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 to elevate the flavor.

Add Orzo and Chicken

Next, stir in the orzo and cook for an additional 2 minutes, allowing it to lightly toast. Add the shredded chicken, dried thyme, black pepper, and Worcestershire sauce if you crave a little extra flavor. Mix everything well.

Pour in Liquids

Now, it’s time to bring it all together! Add the chicken broth and cream to the pan. Bring the mixture to a gentle simmer, then reduce the heat to low. Cover and let it cook for 8–10 minutes, stirring occasionally, until the orzo is tender.

Add Cheese

Once the orzo is cooked, it’s cheese time! Stir in 1 cup of mozzarella and the grated Parmesan cheese. Mix until creamy and melted.

Bake the Casserole

Preheat your oven to 375°F (190°C). Sprinkle the remaining 1/2 cup of mozzarella over the top of the casserole. Bake uncovered for 10–15 minutes until it’s bubbly and golden brown.

Serve

After baking, let the casserole rest for 5–10 minutes before serving. For an extra touch, garnish with fresh thyme or parsley, and enjoy!

Best Ways to Enjoy It

This casserole is delightful on its own, but you can elevate the meal with a crisp side salad or some roasted vegetables. A glass of white wine pairs beautifully, while a warm loaf of crusty bread is perfect for soaking up every last bit.

Keeping Leftovers Fresh

Store your leftover casserole in an airtight container in the fridge for up to 3 days. Reheat in the microwave or oven until warmed through. If you want to freeze it, cover the casserole tightly with foil and store it in the freezer for up to 2 months. Just make sure to thaw overnight in the fridge before reheating.

Helpful Cooking Tips

• For extra flavor, sauté your onions a bit longer until they’re almost caramel-colored.
• If you’re short on time, using rotisserie chicken can save you a lot of prep work.
• Feel free to play around with your cheese! A sharp cheddar or gouda can add a nice twist.
• Don’t skip resting the casserole before serving; it helps the flavors settle and makes for easier serving.

Creative Twists

Want to put your unique spin on this dish? Try adding sautéed mushrooms for an earthy depth, or sprinkle some crispy fried onions on top for an extra crunchy finish. For a lighter version, use whole wheat orzo or swap the heavy cream with a dairy-free alternative.
