Method
 

Preparation
  1. Preheat the Oven to 375°F (190°C).
  2. In a skillet, add a drizzle of olive oil over medium heat. Once hot, toss in the diced onion and minced garlic. Sauté until fragrant and golden, about 3-4 minutes.
  3. Stir in the sliced mushrooms and sauté for another 5 minutes until soft and releasing their juices.
  4. Add the chicken breast, cut into bite-sized pieces. Season with salt, pepper, and herbs. Cook until chicken is no longer pink, about 6-8 minutes.
Combining and Baking
  1. In a large mixing bowl, combine cream of mushroom soup and sour cream. Stir until well combined, then fold in the sautéed chicken and mushroom mixture.
  2. Add half of the shredded cheese to the mixture, reserving the rest for topping.
  3. Pour the mixture into a greased 9x13 inch casserole dish.
  4. Sprinkle the remaining cheddar cheese evenly on top.
  5. Bake for 25-30 minutes until bubbly and golden brown.
  6. Let casserole rest for a few minutes before serving.

Notes

Consider adding frozen peas or spinach for extra nutrition. Fresh herbs can enhance the flavor. You can add cooked rice or pasta for a one-pot meal. For a spicier twist, consider adding red pepper flakes or hot sauce.
