Step‑by‑Step Instructions for French Onion Chicken Orzo Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C), allowing the warmth to envelop your kitchen. This temperature ensures the casserole achieves the perfect bubbly, golden finish later on. While the oven is warming, gather your ingredients so you're ready to create your delightful French Onion Chicken Orzo Casserole.
Step 2: Caramelize the Onions
In a large oven-safe skillet, melt 2 tablespoons of unsalted butter and 2 tablespoons of olive oil over medium-low heat. Add in thinly sliced yellow onions, sugar, and salt, stirring occasionally. Cook for 30 to 40 minutes until the onions are golden and caramelized, with a sweet aroma filling the air. Add minced garlic in the last 2 minutes to deepen the flavor.
Step 3: Brown the Chicken
While the onions caramelize, heat a separate skillet over medium heat. Season your shredded chicken with salt and pepper, then add it to the pan. Sauté for about 5–7 minutes until the chicken is golden and heated through. If your skillet is large enough, you can use the same one as the onions after removing them. This method infuses the chicken with flavor from the onions.
Step 4: Toast the Orzo
Once the onions are caramelized, stir in 1 cup of orzo into the skillet with the onions. Allow the orzo to cook for about 2 minutes, stirring frequently to toast it slightly and enhance its flavor. You’ll notice the grains beginning to change color, giving them a lovely nutty aroma that complements the onions beautifully.
Step 5: Combine Ingredients
Carefully fold the browned chicken back into the skillet with the onions and toasted orzo. Sprinkle in 1 teaspoon of dried thyme and freshly cracked black pepper to taste. If you’d like a tangy note, add a splash of Worcestershire sauce. Stir everything together until well combined, and prepare for the next step.
Step 6: Add Liquids and Simmer
Pour in 3 cups of low-sodium chicken broth and 1 cup of heavy cream. Bring the mixture to a gentle simmer. Cover the skillet and let it cook for 8–10 minutes, stirring occasionally until the orzo is tender but still has a slight bite. Keep an eye on it to prevent the orzo from becoming mushy.
Step 7: Incorporate Cheese
Remove the lid and stir in 1 cup of shredded mozzarella cheese and ⅓ cup of grated Parmesan cheese. As you stir, watch for the cheese to melt completely into a creamy sauce, enveloping the orzo and chicken beautifully. This combination is what makes your French Onion Chicken Orzo Casserole rich and indulgent.
Step 8: Bake the Casserole
Transfer the skillet to your preheated oven without covering it. Sprinkle the remaining mozzarella cheese on top to achieve a beautiful, cheesy crust. Bake for 20–25 minutes until the casserole is bubbling and golden brown on the surface. The aroma that fills your kitchen will be simply irresistible.
Step 9: Rest Before Serving
Once out of the oven, let your casserole rest for about 5–10 minutes. This step allows the flavors to meld and the dish to set, making serving easier. Optionally, garnish with fresh thyme or parsley for an extra pop of color as you prepare to serve this comforting meal to your loved ones.
