Ingredients

Scale
  • 1 (30 oz / 850 g) package frozen hashbrowns, thawed (shredded style preferred)
  • 2 cups (200 g) sharp cheddar cheese, shredded (reserve 1 1/2 cups / 150 g for topping)
  • 1 cup (100 g) mozzarella cheese, shredded
  • 1 cup (240 ml) sour cream, full-fat or light (Greek yogurt can be used as substitute)
  • 1 cup (240 ml) mayonnaise
  • 1 teaspoon onion powder
  • 1/2 teaspoon garlic powder
  • 1 teaspoon salt (adjust to taste)
  • 1/2 teaspoon black pepper, freshly ground preferred
  • 1 1/2 cups (150 g) crushed cornflakes
  • 4 tablespoons (56 g) unsalted butter, melted

Instructions

  1. Preheat your oven to 350°F (175°C) and lightly grease a 9×13 inch (23×33 cm) baking dish with butter or non-stick spray.
  2. In a large mixing bowl, gently fold together the thawed hashbrowns, 1 1/2 cups (150 g) shredded sharp cheddar, mozzarella, sour cream, mayonnaise, onion powder, garlic powder, salt, and black pepper. Avoid overmixing to keep potatoes fluffy.
  3. Transfer the mixture evenly into the prepared baking dish, spreading it out gently with a spatula to a level surface without packing down.
  4. In a small bowl, toss the crushed cornflakes with melted butter and the remaining 1 1/2 cups (150 g) shredded cheddar cheese.
  5. Sprinkle the topping evenly over the casserole, covering all edges for maximum crispiness.
  6. Bake uncovered for 45-55 minutes, until edges are golden brown and the center is bubbling.
  7. Let the casserole rest for about 10 minutes before serving to help it set and make slicing easier.

Notes

Thaw and drain hashbrowns well to avoid sogginess. Do not overmix to keep texture light. Toss cornflakes with melted butter for a crispy topping. Tent with foil if topping browns too quickly. Let casserole rest before serving for easier slicing. For dairy-free, use vegan cheese and substitutes for sour cream and mayonnaise. Fresh herbs can be added for brightness.
