Creamy, cheesy baked potato casserole with chicken and broccoli—perfect comfort food!

Ingredients

  • 4 large russet potatoes peeled and cubed
  • 2 cups cooked chicken breast diced
  • 1 head broccoli cut into florets
  • 1 cup sour cream or Greek yogurt
  • ½ cup milk or skim milk
  • 2 cups shredded cheddar cheese
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • Salt and pepper to taste
  • ½ cup breadcrumbs
  • 2 tablespoons melted butter

Instructions

Step 1: Preheat Your Oven

  • Set your oven to 375°F (190°C) and grease a 9x13-inch baking dish.

Step 2: Cook the Potatoes

  • Bring a large pot of salted water to a boil. Add the cubed potatoes and cook for about 10 minutes, or until just tender. Drain and set aside.

Step 3: Blanch the Broccoli

  • In the same pot, boil water again and blanch the broccoli florets for 3 minutes. Drain and rinse with cold water to preserve color and prevent overcooking. Set aside.

Step 4: Make the Creamy Sauce

  • In a large bowl, combine the sour cream (or Greek yogurt), milk, 1 cup of shredded cheddar cheese, garlic powder, onion powder, salt, and pepper. Whisk until smooth and well blended.

Step 5: Combine Everything

  • Gently fold in the cooked potatoes, diced chicken, and blanched broccoli. Stir until all the ingredients are coated with the creamy sauce.
  • Transfer the mixture into the prepared baking dish and spread it out evenly.

Step 6: Add Toppings

  • Mix the breadcrumbs with the melted butter in a small bowl. Sprinkle the remaining 1 cup of cheddar cheese over the casserole, followed by the breadcrumb mixture for a crispy, golden finish.

Step 7: Bake

  • Place the dish in the preheated oven and bake for 20–25 minutes, or until the cheese is bubbly and the top is golden brown.
  • Let cool for 5 minutes before serving to help the casserole set and make slicing easier.
