How to Make French Onion Chicken Orzo Casserole

This delectable casserole comes together in just a few simple steps, starting with caramelized onions that lay the foundation for rich, savory flavor. Then, you’ll mix in orzo and chicken before tossing everything together in a creamy sauce and baking it to perfection. Here’s what you’ll need to create this comforting meal.

Ingredients

Gather these items to get started:

• 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)

Feel free to substitute heavy cream with half-and-half for a lighter dish, or use vegetable broth for a vegetarian-friendly twist!

Directions

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. Add the minced garlic during the last 1–2 minutes of cooking.
2. Add orzo and chicken: Stir in the orzo and toast for 2 minutes. Then, add the shredded chicken, dried thyme, black pepper, and Worcestershire sauce if you’re using it. Mix well.
3. Pour in liquids: Add the chicken broth and heavy cream. Bring everything to a gentle simmer. Lower the heat, cover, and cook for 8–10 minutes, stirring occasionally, until the orzo is tender.
4. Incorporate cheese: Stir in 1 cup of mozzarella and the Parmesan cheese. Mix until melted and creamy.
5. Bake the casserole: Preheat your oven to 375°F (190°C). Sprinkle the remaining 1/2 cup of mozzarella over the top. Bake uncovered for 10–15 minutes until bubbly and golden on top.
6. Serve: Allow the casserole to rest for 5–10 minutes before serving. Garnish with fresh thyme or parsley if desired.

Serving Suggestions

This casserole pairs beautifully with a simple green salad dressed in vinaigrette, providing a refreshing contrast to its richness. You might also consider crusty bread or garlic bread on the side, perfect for soaking up any leftover creamy sauce. If you’re in the mood for a heartier meal, serve it alongside roasted vegetables or a side of sautéed greens for a delightful mix of textures.

Storage & Reheating

To keep leftovers fresh, store them in an airtight container in the fridge for up to 3-4 days. You can also freeze the casserole before baking it—just wrap it tightly in plastic wrap and aluminum foil. When you’re ready to enjoy it, defrost in the fridge overnight, then bake until heated through. For reheating, simply place in the oven at 350°F (175°C) until warmed, or reheat individual portions in the microwave.

Pro Tips

For an even more decadent dish, consider adding sautéed mushrooms along with the onions. In addition, using a mix of cheeses like Gruyère and mozzarella can elevate the flavor profile. If you’re looking for shortcuts, pre-cooked rotisserie chicken not only saves time but adds fantastic flavor without effort.

Variations

Feel free to put your spin on this casserole! Consider adding a pinch of red pepper flakes for heat or substitute the shredded chicken with cooked sausage for a different protein. You can also experiment with seasonal vegetables such as spinach or zucchini to include some wholesome greens.

FAQs

Can I use a different pasta instead of orzo?
Yes! While orzo adds a unique texture, you could substitute it with any small pasta shape, such as ditalini or even quinoa for a gluten-free option.

What can I do with leftovers?
Leftovers can be repurposed into stuffed bell peppers or added to a soup for a quick and hearty meal.

Is it possible to make this recipe vegetarian?
Absolutely! Omit the chicken and replace the chicken broth with vegetable broth. You can also add more vegetables for added nutrition and flavor!
