For the Casserole

How to Make French Onion Chicken Orzo Casserole

Step 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 they are deeply caramelized.
During the last 1–2 minutes of cooking, add minced garlic and cook until fragrant.

Step 2: Toast the Orzo

Stir in the orzo pasta. Cook for an additional 2 minutes to lightly toast it.

Step 3: Combine Ingredients

Add in the shredded chicken, dried thyme, black pepper, and Worcestershire sauce (if using). Mix everything well.

Step 4: Add Liquids

Pour in the chicken broth and heavy cream. Bring this mixture to a gentle simmer.

Step 5: Simmer Until Tender

Reduce heat to low, cover the skillet, and let it cook for about 8–10 minutes. Stir occasionally until the orzo is tender.

Step 6: Incorporate Cheeses

Stir in 1 cup of mozzarella cheese along with Parmesan cheese until melted and creamy.

Step 7: Prepare for Baking

Preheat your oven to 375°F (190°C). Sprinkle the remaining ½ cup of mozzarella cheese on top of the casserole.

Step 8: Bake

Bake uncovered for about 10–15 minutes until bubbly and golden on top.
