Instructions For French Onion Chicken Orzo Casserole
Follow these simple steps to prepare this delicious dish:
First Step : Preheat Your Oven
Preheat your oven to 375°F (190°C). While it heats, spray a large baking dish with nonstick cooking spray for easy cleanup.
Second Step : Prepare The Chicken
Season your chicken breasts with salt and pepper on both sides. In a skillet over medium heat, add olive oil and sear each breast for about 4-5 minutes per side until golden brown.
Third Step : Sauté The Onions
In the same skillet, add sliced onions and cook them on medium-low heat until they become caramelized. This should take around 15-20 minutes; stir occasionally to prevent burning.
Fourth Step : Cook The Orzo
In a separate pot, bring beef broth to a boil and add orzo pasta. Cook according to package instructions until al dente—usually about 8-10 minutes. Drain any excess liquid once cooked.
Fifth Step : Combine Ingredients
In your prepared baking dish, combine the cooked orzo, sautéed onions, Worcestershire sauce, garlic powder, and seared chicken. Mix thoroughly so everything is coated with flavor.
Sixth Step : Bake And Serve
Sprinkle shredded cheese evenly over the top and bake in your preheated oven for about 25-30 minutes until bubbly and golden brown. Transfer to plates and drizzle with sauce for the perfect finishing touch.

Expert Tips
Here are some helpful tips to ensure the best results for your dish:
- Choose Quality Ingredients: Using fresh ingredients will enhance flavors significantly in this casserole.
- Don’t Rush Caramelization: Take your time when caramelizing onions; it brings out their sweetness and deepens flavor.
- Let It Rest Before Serving: Allowing the casserole to rest for about five minutes after baking helps set everything together for easier serving.
Cooking Instructions
To make the French Onion Chicken Orzo Casserole, start by preheating your oven to 375°F (190°C). In a large skillet, melt butter over medium heat. Add sliced onions and cook for about 15 minutes or until they become soft and caramelized. Stir frequently to avoid burning. Once done, set the onions aside.
In the same skillet, season diced chicken breasts with salt and pepper. Brown the chicken on all sides for about 5-7 minutes. Combine the caramelized onions with the chicken, adding garlic, thyme, and rosemary for added flavor.
Next, add uncooked orzo pasta to the skillet along with chicken broth and heavy cream. Stir everything well to combine. Bring the mixture to a gentle simmer, then transfer it to a greased casserole dish. Cover it with aluminum foil and bake for 25 minutes.
After 25 minutes, remove the foil and sprinkle shredded cheese on top. Bake uncovered for an additional 10-15 minutes or until the cheese is golden and bubbly. Allow it to rest for a few minutes before serving.
Serving Suggestions
This French Onion Chicken Orzo Casserole is perfect as a standalone dish but can also be enhanced with various accompaniments:
- A fresh garden salad: A simple green salad dressed with vinaigrette complements the richness of the casserole.
- Garlic bread: Serve warm garlic bread on the side to soak up any delicious sauce from your casserole.
- Steamed vegetables: Lightly steamed broccoli or green beans provide a colorful plate and add extra nutrition.

FAQs
What can I use instead of orzo in this casserole?
If you cannot find orzo pasta or prefer a different option, consider using other small pasta shapes such as ditalini or acini di pepe. Alternatively, you could substitute rice; however, adjust cooking time accordingly since rice typically takes longer to cook than orzo.
