Ingredients for French Onion Chicken Casserole

To create a delicious French Onion Chicken Casserole, you’ll need the following ingredients:

  • 4 boneless, skinless chicken breasts
  • 2 large onions, thinly sliced
  • 4 cloves of garlic, minced
  • 1 can (10.5 oz) of French onion soup
  • 1 cup of cream of mushroom soup
  • 1 cup of shredded Swiss cheese
  • 1 cup of grated Parmesan cheese
  • 2 tablespoons of olive oil
  • 1 teaspoon of dried thyme
  • Salt and pepper to taste
  • 1 cup of cooked rice or quinoa (optional for a heartier meal)

Step-by-Step Instructions

Follow these easy steps to prepare your French Onion Chicken Casserole:

  1. Prepare the Chicken: Preheat your oven to 375°F (190°C). Season the chicken breasts with salt, pepper, and dried thyme.
  2. Sauté the Onions: In a large skillet, heat the olive oil over medium heat. Add the sliced onions and sauté for about 10-15 minutes, or until they become soft and caramelized. Stir in the minced garlic and cook for an additional minute.
  3. Mix the Soups: In a large bowl, combine the French onion soup and cream of mushroom soup. Stir until well mixed.
  4. Assemble the Casserole: In a greased 9×13-inch baking dish, place the seasoned chicken breasts in a single layer. Pour the soup mixture over the chicken, making sure they are evenly covered.
  5. Add Onions and Cheese: Spoon the sautéed onions over the soup-covered chicken. Sprinkle the shredded Swiss cheese and grated Parmesan cheese evenly on top.
  6. Bake: Cover the dish with aluminum foil and bake for 25 minutes. Then, remove the foil and bake for an additional 15-20 minutes, or until the chicken is cooked through and the cheese is bubbly and golden brown.
  7. Optional – Add Rice or Quinoa: If using, stir in the cooked rice or quinoa into the casserole during the last 10 minutes of baking, ensuring it is well distributed.
