Ingredients

What you’ll need

Gathering these items will set you up for a flavorful feast:

• 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 use half and half for a 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 experiment with substitutions based on your pantry—perhaps swapping in a different type of cheese or using fresh herbs for an extra pop of flavor.

Directions

How to prepare it

1. 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.
2. Add Orzo and Chicken: Stir in the orzo and cook for 2 minutes to let it lightly toast. Add the shredded chicken, thyme, pepper, and Worcestershire sauce if you’re using it. Mix well.
3. Pour in Liquids: Add the chicken broth and cream to the mixture. Bring everything to a gentle simmer. Reduce the 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 cheese and the Parmesan cheese until melted and creamy.
5. Bake the Casserole: Preheat your oven to 375°F (190°C). Sprinkle the remaining 1/2 cup mozzarella on top. Bake uncovered for 10–15 minutes until bubbly and golden.
6. Serve: Allow the dish to rest for 5–10 minutes before serving. Garnish with fresh thyme or parsley if desired.

How to serve French Onion Chicken Orzo Casserole

Best ways to enjoy it

This casserole is a meal all on its own, but it pairs beautifully with a simple green salad dressed in vinaigrette or warm, crusty bread for mopping up every last bit. Consider adding roasted veggies or a side of garlic bread for a hearty, satisfying dinner experience.

How to store

Storage and reheating tips

To keep leftovers fresh, store any unused casserole in an airtight container in the refrigerator for up to 3 days. Reheat individual portions in the microwave or in the oven at 350°F until warmed through. If you want to freeze it, ensure it cools completely before transferring it to freezer-safe containers, where it will keep well for up to 3 months. Always ensure food is heated to 165°F for safe consumption.

Tips to make

Helpful cooking tips

1. Don’t rush the caramelization of the onions. This step truly intensifies the flavor, but it takes patience!
2. If you prefer a healthier twist, consider using whole grain orzo or substituting half of the cream with Greek yogurt.
3. Experiment with different herbs like rosemary or sage for a unique flavor profile.
