What You’ll Need

To create this delicious French Onion Chicken Orzo Casserole, gather these simple ingredients:

• 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)

How to Make French Onion Chicken Orzo Casserole

Let’s embark on this cozy cooking journey together!

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 let it cook for 2 minutes, lightly toasting it. Then add the shredded chicken, dried thyme, black pepper, and Worcestershire sauce if you’re feeling adventurous. Mix everything together well.

3. Pour in Liquids: Add the chicken broth and cream to the skillet. 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 and has absorbed the flavors.

4. Add Cheese: Stir in 1 cup of mozzarella and the grated Parmesan cheese, mixing until both are 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 of your casserole. Bake uncovered for 10–15 minutes until it’s bubbly and golden on top.

6. Serve: Let it rest for 5–10 minutes before serving. If desired, garnish with fresh thyme or parsley for a touch of color.

Variations & Creative Twists

Elevate your French Onion Chicken Orzo Casserole with these fun variations:

• Herbed Delight: Add fresh herbs like rosemary or sage for an aromatic twist that complements the savory flavors beautifully.
• Vegetable Boost: Incorporate sautéed mushrooms or spinach for added texture and nutrition, making it even heartier.
• Cheesy Variation: Experiment with different cheeses like Gruyère or fontina for a creamy, indulgent spin.
