A creamy, cheesy hash brown casserole with three cheeses and sautéed onions, perfect for comfort food cravings and easy to prepare with simple ingredients.

Ingredients

Scale
  • 1 pound (450g) frozen shredded hash browns
  • 4 tablespoons (56g) unsalted butter, melted
  • 1 medium yellow onion, finely chopped
  • 2 cloves garlic, minced
  • 1 cup (240ml) sour cream
  • 1/2 cup (120ml) mayonnaise
  • 1 cup (100g) shredded sharp cheddar cheese
  • 1 cup (100g) shredded mozzarella cheese
  • 1/2 cup (50g) grated Parmesan cheese
  • 1 teaspoon salt
  • 1/2 teaspoon freshly ground black pepper
  • 2 tablespoons chopped fresh chives or green onions (optional)

Instructions

  1. Preheat the oven to 350°F (175°C) and allow it to reach temperature.
  2. Heat 2 tablespoons of melted butter in a skillet over medium heat. Add the finely chopped onion and cook for about 5 minutes until soft and translucent.
  3. Add the minced garlic and cook for another 30 seconds until fragrant, being careful not to burn it.
  4. In a large mixing bowl, combine sour cream, mayonnaise, and the remaining 2 tablespoons of melted butter. Stir until smooth and creamy.
  5. Let the sautéed onions and garlic cool slightly, then fold them into the creamy mixture.
  6. Season the mixture with salt and freshly ground black pepper and stir well.
  7. Add the frozen hash browns, shredded sharp cheddar, shredded mozzarella, and half of the Parmesan cheese to the bowl. Fold gently to combine without breaking up the potatoes.
  8. Grease a 9×13-inch baking dish and spread the mixture evenly inside. Smooth the top with a spatula.
  9. Sprinkle the remaining Parmesan cheese evenly over the top.
  10. Bake for 45-50 minutes until bubbly around the edges and golden brown on top. If the top browns too quickly, tent loosely with foil.
  11. Remove from oven and let the casserole rest for 10 minutes to set.
  12. Garnish with chopped fresh chives or green onions before serving.

Notes

Do not thaw hash browns fully to keep the casserole crispy. Let the casserole rest for 10 minutes after baking to set properly. If the top browns too fast, tent with foil. For a lighter version, swap mayonnaise with Greek yogurt. Variations include adding vegetables, bacon, or making it dairy-free with substitutes.
