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

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 turn a deep golden color and become caramelized. Add the minced garlic for the last 1–2 minutes of cooking.
Add Orzo and Chicken: Stir in the orzo and cook for 2 minutes, allowing it to toast lightly. Then, add the shredded chicken, thyme, pepper, and Worcestershire sauce if you’re using it. Mix everything together well.
Pour in Liquids: Add the chicken broth and cream to the skillet. Bring the mixture to a gentle simmer, reduce the heat to low, cover, and let it cook for 8–10 minutes. Stir occasionally until the orzo is tender.
Add Cheese: Stir in 1 cup of mozzarella and the Parmesan cheese. Mix until the cheeses melt and create a creamy texture.
Bake the Casserole: Preheat your oven to 375°F (190°C). Sprinkle the remaining 1/2 cup of mozzarella cheese over the top of the casserole. Bake uncovered for 10–15 minutes until it is bubbly and golden on top.
Serve: Allow the casserole to rest for 5–10 minutes before serving. You can garnish with fresh thyme or parsley if you like.
