4.1 Ingredients

To create a mouthwatering French onion chicken casserole, you’ll need the following ingredients:

  • Main Ingredients:
    • 4 chicken breasts (or thighs)
    • 2 large yellow onions, thinly sliced
    • 1 cup Gruyere cheese, shredded
    • 1 cup beef or chicken broth
    • 2 teaspoons fresh thyme
    • 3 cloves garlic, minced
    • Salt and black pepper to taste
  • Optional Ingredients:
    • 1 cup breadcrumbs for topping
    • Fresh parsley for garnish

4.2 Directions

Follow these step-by-step instructions to create your French onion chicken casserole:

Step 1: Preparation

Start by preheating your oven to 350°F (175°C). While the oven is heating, clean and chop the onions, and season the chicken with salt and black pepper. Set aside.

Step 2: Cooking the Onions

In a large skillet over medium heat, add a tablespoon of butter. Once melted, add the sliced onions. Cook slowly, stirring occasionally, until they are caramelized and golden brown, about 20 minutes. Add minced garlic and fresh thyme during the last 5 minutes of cooking to release their flavors.

Step 3: Browning the Chicken

In a separate pan, heat another tablespoon of butter over medium-high heat. Add the seasoned chicken and brown on each side for about 3-4 minutes. The chicken does not need to be cooked through at this point, as it will finish cooking in the oven.

Step 4: Layering the Casserole

In a greased baking dish, layer the caramelized onions evenly at the bottom. Place the browned chicken on top, then pour the broth over the layers. Sprinkle the shredded Gruyere cheese generously over the chicken. If you’re using breadcrumbs, add them as a topping for an extra crunch.

Step 5: Baking Instructions

Cover the baking dish with aluminum foil and bake for 30 minutes. After 30 minutes, remove the foil and bake for an additional 15-20 minutes, or until the cheese is bubbly and lightly golden. Allow it to cool for a few minutes before serving.

4.3 Tips and Advice

To make the most of your French onion chicken casserole, consider the following tips:

  • Ingredient Modifications: For a lighter version, use skinless chicken breasts and low-fat cheese options.
  • Storage and Reheating: Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave until warmed through.
