Description
How to make creamy French Onion Chicken Orzo Casserole with tender chicken and caramelized onions that your whole family will adore.
Ingredients
Scale
- Main Components:
- 1.5 pounds boneless, skinless chicken thighs, cut into 1-inch pieces
- 1.5 cups orzo pasta, uncooked
- 3 large sweet yellow onions, thinly sliced
- 4 cups beef broth
- 1 cup heavy cream
- Flavor Foundation:
- 4 tablespoons unsalted butter
- 4 cloves garlic, minced
- 1/2 cup dry white wine (like Sauvignon Blanc or Pinot Grigio)
- 2 tablespoons all-purpose flour
- 1 tablespoon Worcestershire sauce
- Essential Seasonings:
- 1 teaspoon kosher salt
- 1/2 teaspoon freshly ground black pepper
- 1 teaspoon dried thyme
- Cheesy Topping & Garnish:
- 1.5 cups shredded Gruyere cheese
- 2 tablespoons fresh parsley, chopped
Instructions
- Caramelize Onions: Melt butter in a large pot over medium-low heat. Add thinly sliced onions and cook, stirring occasionally, until deeply golden brown and sweet, about 25-30 minutes. This slow caramelization is essential for authentic French Onion Chicken Orzo Casserole flavor.
- Sear Chicken: Remove caramelized onions from the pot and set aside. Increase heat to medium-high. Add chicken pieces and sear until lightly browned on all sides, about 5-7 minutes. Stir in minced garlic and cook for one minute until fragrant.
- Build Sauce: Deglaze the pot with dry white wine, scraping up any browned bits. Whisk in all-purpose flour for 1 minute. Gradually add beef broth, heavy cream, Worcestershire sauce, dried thyme, salt, and pepper. Simmer until the sauce slightly thickens.
- Cook Orzo: Stir uncooked orzo pasta, cooked chicken, and caramelized onions into the simmering sauce. Bring to a gentle simmer, then cover and cook for 10-12 minutes, stirring occasionally, until the orzo is tender and most liquid is absorbed.
- Bake Casserole: Preheat oven to 375°F (190°C). Transfer the creamy orzo mixture to a 9×13 inch baking dish. Top generously and evenly with shredded Gruyere cheese. Bake for 15-20 minutes until bubbly and the cheese is golden brown.
- Garnish & Serve: Let your comforting French Onion Chicken Orzo Casserole rest for 5 minutes after baking. Garnish with fresh chopped parsley before serving warm. Prepare for rave reviews on this delicious and satisfying dish!
Notes
Slowly caramelize onions until deeply golden brown to develop the essential, rich French onion flavor.
Store leftover casserole in an airtight container in the refrigerator for up to 3-4 days.
While Swiss or provolone can substitute, freshly grated Gruyere provides the iconic nutty, melty topping.
Serve this comforting casserole warm, straight from the oven, alongside a crisp green salad or crusty baguette.
Caramelize onions and sear chicken 1-2 days ahead, storing separately, then assemble and bake just before serving.
