  • 2 cloves garlic, minced
  • 1 teaspoon onion powder
  • 1/2 teaspoon dried thyme
  • Salt and black pepper, to taste
  • Chopped green onions, for garnish (optional)


  1. Preheat the Oven:
  • Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with cooking spray or butter.
  1. Prepare the Ingredients:
  • Cook and dice the chicken breast if not already cooked.
  • Peel and dice the potatoes into bite-sized pieces.
  • Chop the broccoli florets into smaller pieces.
  1. Steam the Potatoes and Broccoli:
  • Place the diced potatoes and chopped broccoli in a large microwave-safe bowl. Add a splash of water and cover with a microwave-safe lid or plate.
  • Microwave on high for 4-5 minutes, or until the vegetables are tender but still slightly firm. Drain any excess water and set aside.
  1. Make the Cheese Sauce:
  • In a saucepan over medium heat, melt 1 tablespoon of butter. Add the minced garlic and cook for 1 minute until fragrant.
  • Stir in the flour and cook for another minute to form a roux.
  • Gradually whisk in the milk until smooth and thickened.
  • Add the sour cream, mayonnaise, onion powder, dried thyme, salt, and black pepper. Stir until well combined and creamy.
  • Remove the saucepan from the heat and stir in 1 cup of shredded cheddar cheese until melted and smooth.
  1. Assemble the Casserole:
  • In the prepared baking dish, layer half of the diced potatoes and broccoli. Sprinkle half of the diced chicken over the vegetables.
  • Pour half of the cheese sauce over the chicken and vegetables, spreading it out evenly.
  • Repeat the layers with the remaining potatoes, broccoli, chicken, and cheese sauce.
  1. Bake the Casserole:
  • Cover the baking dish with aluminum foil and bake in the preheated oven for 25-30 minutes, or until the casserole is hot and bubbly.
  1. Add Cheese Topping:
  • Remove the foil from the baking dish and sprinkle the remaining 1/2 cup of shredded cheddar cheese over the top of the casserole.
  1. Broil the Casserole:
  • Turn on the broiler and broil the casserole for 2-3 minutes, or until the cheese is golden and bubbly.
  1. Garnish and Serve:
