Oven-Roasted Hash Brown Cakes

These oven-roasted hash brown cakes are a sophisticated take on a breakfast classic, offering a wonderful contrast between the crisp, golden exterior and the tender, savoury centre. By combining coarsly grated potatoes with paper-thin slices of onion, the dish develops a deep, caramelised flavour that elevates it beyond a simple potato side. They are an excellent vegetarian option for a weekend brunch or a light evening meal.

Roasted in the oven rather than fried on the hob, these cakes are remarkably easy to prepare for a group. The slow-roasting process allows the starch to crisp up beautifully while the butter ensures a rich, indulgent finish. Serve them alongside poached eggs and grilled tomatoes for a hearty vegetarian breakfast, or as a crunchy accompaniment to a fresh green salad.

Ingredients for Oven-Roasted Hash Brown Cakes

  • 240g paper-thin onion slices

  • 450g Yukon Gold potatoes, peeled, coarsely grated on large holes of box grater or in processor (about 375g )

  • 1 teaspoon salt, divided

  • 2 tablespoons unsalted butter, melted

How to make Oven-Roasted Hash Brown Cakes

Preheat oven to 218°C. Butter large rimmed nonstick baking sheet. Place onion in large bowl. Toss potatoes with 1/2 teaspoons salt in medium bowl. Let stand 5 minutes. Using hands, squeeze out excess liquid from potatoes. Add potatoes, 1/2 teaspoons salt, and melted butter to onion. Toss to coat.

Divide mixture into 4 mounds on prepared baking sheet, spacing apart. Roast 15 minutes, then turn mounds over with spatula, pressing down to flatten to 4-inch-diameter rounds (cakes will still be soft). Reduce oven temperature to 177°C; bake until cakes are golden and crisp around edges, about 45 minutes longer.
