  • 4 large russet potatoes, peeled and cubed

  • 1 cup sour cream
  • 1/2 cup milk
  • 2 cups shredded cheddar cheese
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • Salt and pepper to taste
  • 1/2 cup breadcrumbs
  • 2 tablespoons melted butter


Step 1: Prepare the Ingredients

  1. Cook the Potatoes:
    • Preheat your oven to 375°F (190°C).
    • Place the cubed potatoes in a large pot and cover with water. Add a pinch of salt and bring to a boil. Cook until the potatoes are just tender, about 10-15 minutes. Drain and set aside.
  2. Cook the Broccoli:
    • Steam the broccoli florets until they are just tender, about 5 minutes. Alternatively, you can microwave the broccoli with a splash of water in a covered microwave-safe dish for about 3-4 minutes. Drain any excess water.

Step 2: Prepare the Creamy Sauce

  1. Mix the Sauce Ingredients:
    • In a large mixing bowl, combine the sour cream, milk, shredded cheddar cheese, garlic powder, onion powder, salt, and pepper. Mix until well combined.

Step 3: Assemble the Casserole

  1. Combine the Ingredients:
    • Add the cooked potatoes, diced chicken, and steamed broccoli to the bowl with the creamy sauce. Gently stir to coat all the ingredients evenly.
  2. Transfer to Baking Dish:
    • Transfer the mixture to a greased 9×13-inch baking dish, spreading it out evenly.

Step 4: Prepare the Topping

  1. Mix the Breadcrumbs and Butter:
    • In a small bowl, combine the breadcrumbs and melted butter. Stir until the breadcrumbs are evenly coated.
  2. Add the Topping:
    • Sprinkle the breadcrumb mixture evenly over the top of the casserole.

Step 5: Bake the Casserole

  1. Bake:
    • Place the casserole in the preheated oven and bake for 25-30 minutes, or until the top is golden brown and the casserole is heated through.

Step 6: Serve

  1. Cool Slightly:
    • Allow the casserole to cool for a few minutes before serving.
  2. Serve:
    • Serve the Baked Potato Chicken and Broccoli Casserole hot, garnished with fresh herbs if desired.

Cook Notes and Variations

Cook Notes:

  • Potatoes: Make sure the potatoes are just tender and not overcooked to prevent them from becoming mushy in the casserole.

  • Bacon Addition:
    • Add 1/2 cup of cooked and crumbled bacon to the mixture for extra flavor.
  • Spicy Casserole:
    • Add a pinch of cayenne pepper or red pepper flakes to the sauce for a spicy kick.
  • Vegetarian Version:
    • Substitute the chicken with a can of drained and rinsed chickpeas or additional vegetables such as carrots and bell peppers.
