Ingredients

  • 650 g (22 oz) frozen hash browns, thawed
  • 2 tablespoons butter, divided
  • 2 tablespoons olive oil, divided
  • 1 small white onion, halved and thinly sliced
  • 2 garlic cloves, finely minced
  • ½ teaspoon granulated sugar
  • 1 egg, whisked
  • 1 cup grated Gruyère cheese
  • ½ cup sharp cheddar cheese
  • Kosher salt, to taste
  • Black pepper, to taste
  • Chopped parsley, for garnish

Instructions

  1. Preheat oven to 400°F (200°C) and line a large baking sheet with parchment paper.
  2. Squeeze excess liquid from thawed hash browns using a clean dishtowel. Place in a large mixing bowl.
  3. In a skillet over medium heat, heat 1 tablespoon olive oil and 1 tablespoon butter. Add onions and garlic, sprinkle with sugar, and cook for about 10 minutes until caramelized.
  4. Add the caramelized onion mixture to the bowl with potatoes. Pour in the remaining oil and butter, then toss to combine.
  5. Stir in the whisked egg, 1 cup Gruyère cheese, and a pinch each of salt and pepper.
  6. Spread mixture evenly on the prepared baking sheet without pressing down. Sprinkle the top with the cheddar cheese.
  7. Bake for 35 minutes, or until the top is golden and bubbling.
  8. Remove from oven, garnish with chopped parsley, slice into squares, and serve warm.

Notes

  • Thoroughly drying the potatoes is key to achieving a crispy texture.
  • Can be prepped ahead and baked just before serving.
  • Use freshly grated cheese for the best melt and flavor.
  • Swap in mozzarella or Monterey Jack for a milder version.
  • Can be baked in individual muffin tins for portioned servings.
