Roasted Potato Wedges with Rosemary Butter

These roasted potato wedges with rosemary butter offer a sophisticated twist on a classic family favourite. By starting the cooking process under foil, the potatoes steam slightly to ensure a fluffy interior before crisping up to a deep golden brown in the high heat of the oven. The addition of fresh rosemary infused into melted butter provides a fragrant, savoury finish that elevates the humble baking potato into something truly special.

This vegetarian side dish is incredibly versatile, pairing beautifully with a Sunday roast, grilled halloumi, or simply served as a comforting snack. Using organic russet or floury baking potatoes ensures the best texture, while the specific roasting method guarantees a satisfying crunch. It is a simple yet reliable recipe for anyone seeking a quick, homemade accompaniment that delivers on both flavour and texture.

  • 1 1/2 tablespoons olive oil

  • 900g russet (baking) potatoes (preferably organic

How to make Roasted Potato Wedges with Rosemary Butter

Put oven rack in lower third of oven and preheat oven to 260°C. Oil bottom of a shallow baking pan (15 by 10 by 1 inch) with 1/2 tablespoons oil.

Cut each potato lengthwise into 8 wedges and toss with salt, pepper, and remaining tablespoon oil in a large bowl. Arrange potato wedges, flat sides down, in baking pan, then cover pan tightly with foil and roast 10 minutes. Remove foil and roast 10 minutes more. Loosen potatoes with a metal spatula, then turn over onto other flat sides and roast until tender and golden, about 10 minutes.

While potatoes roast, melt butter with rosemary in a small saucepan over moderately low heat. Loosen potatoes with spatula, then transfer to a serving dish or plates and spoon rosemary butter over them.
