How to make French Onion Chicken Orzo Casserole

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)

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. 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, allowing it to lightly toast. Add the shredded chicken, thyme, pepper, and Worcestershire if using. Mix well.

3. Pour in Liquids: Add the chicken broth and cream. Bring 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 the 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: Let it rest for 5–10 minutes before serving. Garnish with fresh thyme or parsley if desired.

Tips to make French Onion Chicken Orzo Casserole

• Caramelize the onions slowly: Taking your time will bring out the best flavors, so don’t rush this step!
• Use rotisserie chicken: It saves time and adds great flavor.
• Mix cheeses: Try adding a blend of cheeses for a richer taste. Cheddar or Gruyère work well with this dish.

Variation

You can swap the orzo for other small pasta shapes, like ditalini or even mini shells. Additionally, if you want a lighter version, use half and half instead of heavy cream. For a vegetarian option, replace the chicken with sautéed mushrooms or a mix of seasonal vegetables.
