Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
4 cups frozen hash brown potatoes (thawed)
1 cup sour cream
1 cup shredded cheddar cheese
1 1/2 cups crushed cornflakes
Directions
Start by preheating your oven to 180°C (350°F). Lightly grease a medium-sized baking dish to prevent sticking.
In a large mixing bowl, combine the thawed hash brown potatoes, sour cream, and shredded cheddar cheese. Stir everything together until the potatoes are evenly coated and the mixture looks creamy and well blended.
Transfer the mixture into the prepared baking dish and spread it out evenly using a spatula. Make sure the surface is level so it cooks evenly.
Next, sprinkle the crushed cornflakes evenly over the top. This layer will create that signature crispy texture once baked.
Place the casserole in the preheated oven and bake for 40 to 45 minutes, or until the top is golden brown and the edges are bubbling slightly.
Remove from the oven and let it sit for about 5 minutes before serving. This helps the casserole set and makes it easier to scoop.

Variations
You can easily adapt this casserole to suit your taste. For a richer flavor, try adding a small amount of cream cheese to the mixture. If you prefer a sharper taste, substitute part of the cheddar with a stronger cheese.
To add a bit of texture and flavor, you can mix in finely chopped onions or sautéed mushrooms. For a lighter version, use low-fat sour cream and reduced-fat cheese.
If you want a different topping, crushed crackers or breadcrumbs can be used instead of cornflakes while still giving you that satisfying crunch.
Storage/Reheating
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Make sure the casserole has cooled completely before storing.
To reheat, place a portion in the oven at 170°C (325°F) for about 15–20 minutes, or until heated through. This helps maintain the crispy topping. If using a microwave, heat in short intervals, though the topping may soften slightly.
You can also freeze the casserole before baking. Wrap it tightly and freeze for up to 2 months. When ready to use, thaw overnight in the refrigerator and bake as directed.
