How to Make French Onion Chicken Orzo Casserole
-
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 to release its fragrant goodness.
-
Add Orzo and Chicken: Stir in the orzo and allow it to lightly toast for about 2 minutes. Then, add the shredded chicken, dried thyme, and black pepper, incorporating everything well. Feel free to add Worcestershire sauce or balsamic glaze at this point for even more flavor!
-
Pour in Liquids: Add the low-sodium chicken broth and cream, bringing the mixture 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 that delicious flavor.
-
Add Cheese: Stir in 1 cup of mozzarella cheese and the grated Parmesan cheese. Mix until everything is melted and creamy, creating a cozy blanket of cheesy goodness throughout.
-
Bake the Casserole: Preheat your oven to 375°F (190°C). Sprinkle the remaining 1/2 cup of mozzarella over the top of the casserole and bake uncovered for 10–15 minutes, or until it’s bubbly and golden on top.
-
Serve: Let your delicious French Onion Chicken Orzo Casserole rest for 5–10 minutes before serving. For a lovely finishing touch, garnish with fresh thyme or parsley if desired.
