Gather these items

For this recipe, you’ll need:

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 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 swap out ingredients based on your pantry staples. For instance, you can use any type of pasta you have on hand or substitute the heavy cream with a plant-based alternative for a lighter or dairy-free version.

Step-by-step instructions

Caramelize the Onions: Melt the unsalted butter and olive oil in a large oven-safe skillet or Dutch oven over medium heat. Add the sliced onions, sugar, and salt. Cook for 20–25 minutes, stirring occasionally, until the onions are a beautiful golden brown. In the last 1–2 minutes of cooking, stir in the minced garlic.
Add Orzo and Chicken: Stir the orzo into the onion mixture and cook for 2 minutes to give it a light toast. Then, add the cooked shredded chicken, dried thyme, and freshly ground black pepper. If you’re using Worcestershire sauce or balsamic glaze, mix it in here.
Pour in Liquids: Add the chicken broth and heavy cream to the skillet. Bring the mixture to a gentle simmer, reducing the heat to low. Cover and let it cook for 8–10 minutes, stirring occasionally, until the orzo is tender.
Add Cheese: Mix in 1 cup of mozzarella and the Parmesan cheese, stirring until everything is melted and creamy.
Bake the Casserole: Preheat your oven to 375°F (190°C). Sprinkle the remaining 1/2 cup mozzarella over the top of the dish and bake it uncovered for 10–15 minutes until it’s bubbly and golden brown.
Serve: Allow the casserole to rest for 5–10 minutes before serving. Garnish with fresh thyme or parsley for a lovely touch.

Best ways to enjoy it

This casserole is a standalone meal, but it pairs wonderfully with a fresh salad or some crusty bread. For a complete dinner experience, consider serving it with steamed vegetables or a side of roasted Brussels sprouts to balance the richness of the casserole.

Keeping leftovers fresh

To store your French onion chicken orzo casserole, let it cool completely, then transfer it to an airtight container. It will keep well in the refrigerator for up to 3 days. If you want to freeze it, portion it into individual servings and store it in freezer-safe containers for up to 3 months. When reheating, be sure to add a splash of broth or cream to prevent dryness.

Helpful cooking tips

Onion Caramelization: Patience is key! Don’t rush the caramelization process; low and slow is the way to achieve deep, rich flavors.
Chicken Options: Using rotisserie chicken is a huge time-saver, but you can also boil or grill chicken breasts for a healthier version.
Cheese Varieties: While mozzarella and Parmesan are delicious, experimenting with Gruyère or Fontina can add an impressive twist.

Creative twists

Feel free to get creative with this casserole! You can add mushrooms for an earthy depth, or toss in some spinach or kale for extra nutrition. Swap out the mozzarella for a sharp cheddar to enhance the flavor profile, or try using a burst of herby pesto as a final touch before serving.
