Ingredients Equipment Method Notes

Ingredients
  

  • 2 tbsp olive oil
  • 1 1/2 lbs boneless, skinless chicken breasts, chopped into bite-sized pieces
  • 1 small yellow onion, thinly sliced
  • 1 can (10.5 oz) cream of chicken soup
  • 3/4 cup milk
  • 1 1/2 cups shredded cheddar cheese
  • 1 cup French-fried onions (plus extra for topping)
  • salt and black pepper, to taste

Equipment

  • Large skillet
  • 9x13-inch casserole dish
  • Mixing bowl
  • Wooden spoon or spatula
  • Oven

Method
 

  1. Preheat your oven to 350°F (180°C). Grease a 9×13-inch casserole dish and set it aside.
  2. In a large skillet, heat 1 tablespoon olive oil over medium heat. Add the chopped chicken, season with salt and pepper, and cook until browned and fully cooked. Remove from the skillet and set aside.
  3. In the same skillet, add the remaining tablespoon of olive oil. Sauté the sliced onion until softened and golden, about 5 minutes.
  4. In a large bowl, combine the cooked chicken, sautéed onions, cream of chicken soup, milk, and shredded cheese. Stir until fully incorporated.
  5. Spread the creamy chicken mixture evenly in the prepared casserole dish. Sprinkle the top with French-fried onions and extra cheese, if desired.
  6. Bake for 25–30 minutes, until hot and bubbly and the topping is golden brown. Let cool slightly before serving.

Notes

Try swapping cheddar for mozzarella or Monterey Jack for a different flavor. Add vegetables like broccoli or peas for extra nutrition. Leftovers keep well in the fridge for up to 3 days.
