If you’re looking to simplify your dinner routine while delighting your taste buds, this recipe for French Onion Chicken Orzo Casserole is a fantastic choice. The cooking process involves caramelizing onions for deep flavor, toasting orzo, mixing in shredded chicken, and finally baking it all to bubbly perfection. Let’s break this down.

What you’ll need

Gather these items to get started on your delicious casserole:

• 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 swap out the heavy cream for a lighter option or use different types of cheese based on your pantry!

Directions to follow

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 toast it for 2 minutes. Then, add the shredded chicken, thyme, pepper, and Worcestershire sauce if you decide to use it. Mix well.
3. Pour in Liquids: Add the chicken broth and cream, bringing it to a gentle simmer. Reduce 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 and the Parmesan cheese. Mix until melted and creamy.
5. Bake the Casserole: Preheat oven to 375°F (190°C). Sprinkle the remaining 1/2 cup mozzarella over the top. Bake uncovered for 10–15 minutes until bubbly and golden on top.
6. Serve: Allow it to rest for 5–10 minutes before serving. Garnish with fresh thyme or parsley if desired.

Best ways to enjoy it

This casserole is wonderfully versatile. Serve it as a hearty main dish that pairs beautifully with a side salad for a balanced meal. For a more robust experience, consider serving it alongside garlic bread or roasted vegetables to further enhance the flavors.

Storage and reheating tips

If you find yourself with leftovers (although they might be rare), here’s how to keep them fresh. Allow the casserole to cool completely before storing it in an airtight container. In the refrigerator, it will last for about 3-4 days. For longer storage, freeze in portions for up to three months. When reheating, simply warm it in the oven or microwave until heated through. Make sure to handle leftovers with proper food safety to keep it delicious and safe!

Helpful cooking tips

• Caramelizing onions can be an art; don’t rush it! A slow cook ensures that sweet, deep flavors develop fully.
• If you want a little extra flavor, consider using chicken thighs instead of breast for a juicier texture.
• Feel free to sauté some mushrooms along with the onions for an earthy twist.

Different ways to try it

Get creative with your French Onion Chicken Orzo Casserole! Try adding sautéed spinach or kale for some green goodness, or mix in different cheeses like cheddar for a different flavor profile. You can also try adding spices like smoked paprika for a smoky touch or even a splash of white wine when caramelizing onions for added depth.
