Ingredients

Scale

Base Ingredients

  • 1 bag (30 oz / 850 g) frozen shredded hash browns, thawed
  • 1 can (10.5 oz / 300 g) cream of chicken soup
  • 1 cup (240 ml) sour cream
  • ½ cup (115 g) melted butter
  • ½ cup (80 g) finely chopped onion
  • ½ teaspoon garlic powder
  • ½ teaspoon salt
  • ¼ teaspoon black pepper

Cheese

  • 2 cups (200 g) shredded cheddar cheese, divided

Topping

  • 1 ½ cups (75 g) crushed cornflakes or buttery crackers
  • 3 tablespoons melted butter

Instructions

  1. Preheat the oven: Preheat your oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish to prevent sticking.
  2. Mix the base: In a large bowl, combine the cream of chicken soup, sour cream, ½ cup melted butter, 1 ½ cups of shredded cheddar cheese, chopped onion, garlic powder, salt, and black pepper. Stir thoroughly until the mixture is smooth and well blended.
  3. Add potatoes: Fold the thawed shredded hash browns into the creamy mixture, ensuring the potatoes are evenly coated with the base mixture.
  4. Assemble the casserole: Spread the hash brown mixture evenly into the prepared baking dish. Sprinkle the remaining ½ cup of cheddar cheese evenly over the top of the casserole.
  5. Prepare the topping: In a small bowl, mix the crushed cornflakes (or buttery crackers) with the 3 tablespoons of melted butter until the crumbs are well coated. Sprinkle this mixture evenly over the cheese layer.
  6. Bake: Place the baking dish in the preheated oven and bake uncovered for 45–50 minutes until the casserole is bubbly and the topping is golden brown and crispy.
  7. Serve: Let the casserole cool slightly before serving. This dish pairs perfectly with ham, roasted chicken, or breakfast eggs for a complete meal.

Notes

  • Thaw hash browns completely before mixing to avoid excess moisture in the casserole.
  • You can substitute crushed buttery crackers for cornflakes for a different flavor and texture.
  • For a richer dish, use full-fat sour cream and sharp cheddar cheese.
  • To make it vegetarian, use cream of mushroom soup instead of cream of chicken soup.
  • Leftovers can be stored covered in the refrigerator for up to 3 days and reheated in the oven until warmed through.
