Why You’ll Love This Cheesy Hashbrown Casserole

• Made with only 4 simple ingredients
• No canned soup needed
• Easy make-ahead breakfast or brunch recipe
• Perfect for potlucks, holidays, and family dinners
• Creamy inside with a golden, crispy cheese topping
• Vegetarian-friendly comfort food
• Easy to freeze and reheat

Ingredients

• 1 bag frozen shredded hashbrowns, thawed (about 850–900 g)
• 3 cups shredded sharp cheddar cheese, divided
• 2 cups sour cream
• 1 teaspoon salt, or to taste

Instructions

1. Preheat the oven to 175°C (350°F). Lightly grease a 23 x 33 cm baking dish with butter or nonstick cooking spray.
2. Allow the frozen shredded hashbrowns to thaw slightly. Pat them dry with paper towels to remove extra moisture. This helps the casserole become creamy while keeping the edges nicely golden.
3. In a large bowl, mix the sour cream and salt until smooth.
4. Add the thawed hashbrowns and stir gently until the potatoes are evenly coated.
5. Fold in 2 cups of shredded cheddar cheese, reserving the remaining 1 cup for the topping.
6. Transfer the potato mixture to the prepared baking dish and spread it into an even layer.
7. Sprinkle the remaining cheddar cheese over the top.
8. Bake uncovered for 40 to 45 minutes, until the casserole is hot, bubbling around the edges, and golden on top.
9. For an extra crispy cheesy topping, place the dish on the upper oven rack for the final 5 to 10 minutes. Watch carefully so the cheese does not burn.
10. Let the casserole rest for 10 minutes before serving. This allows it to set and makes it easier to scoop into neat portions.

Benefits of This Easy Potato Casserole

Potatoes provide satisfying carbohydrates that help give your body energy, while cheddar cheese adds protein and calcium. Sour cream creates a creamy texture and adds richness, making this dish filling and comforting.

Because this recipe uses only four ingredients, it is also budget-friendly, quick to prepare, and ideal when you need an easy side dish without spending a long time in the kitchen.

Make-Ahead and Storage Tips

You can prepare this hashbrown casserole the night before, cover it tightly, and refrigerate it until ready to bake. Add about 5 to 10 minutes to the baking time if baking directly from the refrigerator.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat individual portions in the microwave or warm the full casserole in the oven at 160°C (325°F) until heated through.

To freeze, divide the mixture into smaller baking dishes, wrap tightly, and freeze. Bake from frozen at 175°C (350°F), covered for about 30 minutes, then uncovered for another 25 to 30 minutes until hot and golden.

Optional Variations

For a deeper cheese flavor, use extra-sharp cheddar. You can also replace part of the cheddar with smoked cheddar or pepper jack cheese for a slightly different flavor while keeping the recipe simple.
