Ingredients

Unsalted Butter: Used to gently caramelize onions, adding creamy richness without overpowering flavors.
Olive Oil: Provides a subtle fruity undertone and prevents onions from sticking in the skillet.
Yellow Onions: Thinly sliced for optimal caramelization, their natural sugars develop deep golden sweetness.
Garlic Cloves: Minced and stirred in toward the end to add aromatic warmth without burning.
Granulated Sugar: Helps speed up and deepen the caramelization process of the onions.
Kosher Salt: Enhances natural onion flavor and balances the sweetness during cooking.
Dried Thyme: Adds an herbaceous note that complements the richness of the dish.
Freshly Ground Black Pepper: Provides subtle heat and a fresh layer of spices.
Orzo Pasta: Toasted briefly to bring a nutty flavor and prevent mushiness.
Cooked Shredded Chicken: Adds lean protein and heartiness without overwhelming the delicate onion flavors.
Low-Sodium Chicken Broth: Used as the cooking liquid to impart savory depth with controlled saltiness.
Heavy Cream: Creates a creamy, velvety sauce that binds ingredients beautifully.
Shredded Mozzarella Cheese: Incorporated for gooey meltiness and a stretchy cheese texture.
Grated Parmesan Cheese: Adds sharp, nutty flavor enhancing overall savory profile.
Worcestershire Sauce or Balsamic Glaze (optional): Adds complexity and tangy depth to the sauce.

Instructions

Melt Butter and Olive Oil to Start: Begin by melting butter with olive oil in a large oven-safe skillet over medium heat. This combination ensures a rich base with a balanced fat profile for caramelizing the onions evenly and preventing them from burning.
Caramelize Onions Slowly: Add the thinly sliced yellow onions, granulated sugar, and kosher salt to the skillet. Cook gently for 20 to 25 minutes, stirring occasionally until the onions become deeply golden and sweetly caramelized. This slow process brings out their natural sugars, imparting rich flavor and soft texture.
Add Garlic Near End of Caramelization: Stir in the minced garlic during the last 2 minutes of caramelizing. Adding garlic late prevents it from burning and turning bitter while infusing the dish with its fragrant aroma.
Toast the Orzo for Nutty Flavor: Mix the orzo pasta into the skillet and cook for about 2 minutes. Toasting the orzo lightly brings out its nutty flavors and helps maintain a firm texture during cooking.
Combine Chicken and Seasonings: Add the cooked shredded chicken, dried thyme, black pepper, and optional Worcestershire sauce or balsamic glaze. Stir well to evenly coat the chicken and distribute herbs and spices, enhancing overall taste complexity.
Simmer with Broth and Cream: Pour chicken broth and heavy cream into the skillet. Bring the mixture to a gentle simmer, then lower the heat. Cover and cook for 8 to 10 minutes, stirring occasionally to prevent sticking, until the orzo becomes tender and absorbs the flavorful liquid.
Add Cheese for a Creamy Sauce: Stir in 1 cup shredded mozzarella and all the Parmesan cheese until melted and integrated, producing a creamy sauce that binds the ingredients harmoniously and adds richness.
Bake to Golden Perfection: Preheat your oven to 375°F. Evenly sprinkle the remaining 1/2 cup mozzarella cheese on top of the skillet mixture. Bake uncovered for 10 to 15 minutes until the cheese is bubbly, melted, and golden brown, creating a delicious crust that enhances texture and flavor.
Rest and Garnish Before Serving: Let the dish rest for 5 to 10 minutes to allow the cheese to set and flavors to meld. Garnish with fresh thyme or parsley if desired, adding a touch of color and freshness before serving.

You Must Know

Adjust seasoning as needed since broths and cheeses vary in saltiness.
You can swap mozzarella with Fontina or Gruyère for a different cheese profile.
Use an oven-safe skillet to streamline stovetop-to-oven cooking for less cleanup.

Storage Tips

Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop or in the oven to restore creaminess without drying out.

Serving Suggestions

Serve French Onion Chicken Orzo with a crisp green salad or steamed vegetables for a balanced meal. A glass of lightly chilled white wine pairs beautifully with the creamy, cheesy flavors.

Professional Tips

For best caramelization, slice onions uniformly and cook low and slow to develop deep, sweet flavor.
To avoid mushy orzo, toast it before simmering to maintain bite and texture.
Letting the dish rest post-baking ensures the sauce thickens and ingredients meld perfectly.
