Step‑by‑Step Instructions for French Onion Chicken Orzo Casserole

Step 1: Caramelize Onions
In a large skillet, melt 2 tablespoons of butter and 1 tablespoon of olive oil over medium-low heat. Add 2 large sliced yellow onions, stirring well to coat. Cook the onions for 30-40 minutes, stirring frequently, until they turn a rich golden brown and become soft. In the last minute of cooking, add 2 minced garlic cloves for an aromatic punch, and then set the mixture aside.

Step 2: Cook Chicken
While the onions are caramelizing, heat another skillet over medium-high heat. Season 1 pound of boneless chicken thighs or breasts with salt and black pepper. Add the chicken to the hot skillet and brown each side for about 4-5 minutes until golden but not fully cooked through; it will continue cooking in the casserole.

Step 3: Combine Ingredients
Once the onions are ready and set aside, pour 2 cups of beef broth into the skillet, scraping up any delicious browned bits. Stir in 1 cup of uncooked orzo pasta, 1 cup of heavy cream, and a teaspoon of fresh thyme. Then, add the browned chicken pieces to the skillet, combining all ingredients and simmering for 5-7 minutes until the orzo absorbs some of the liquid.

Step 4: Bake
Preheat your oven to 375°F (190°C). In a large baking dish, transfer the orzo and chicken mixture. Mix in half of the Gruyère cheese, and then sprinkle the remaining cheese on top. Bake in the preheated oven for 20-25 minutes until the cheese is melted and bubbly, with a golden crust.

Step 5: Serve
Once baked, remove the French Onion Chicken Orzo Casserole from the oven and let it rest for 5-10 minutes. This will allow the layers to settle before serving. Garnish with fresh thyme or parsley for added color and flavor, then dish out generous portions to share the warmth and comfort of this delightful casserole with family and friends.

No worries at all! If you find yourself without orzo, you can substitute it with other small pasta shapes like ditalini or even gluten-free pasta alternatives for those with dietary restrictions. Just adjust the cooking time as needed, depending on what pasta you choose!
