Mary Berry Parmentier Potatoes are finely diced potatoes that are lightly parboiled, then roasted with garlic, herbs, and butter or oil until crisp and golden. They’re inspired by French cuisine and known for their uniform shape, even browning, and aromatic flavour.
800g potatoes, peeled and cut into small cubes
3 tbsp olive oil or melted butter
2 garlic cloves, crushed
1 tsp dried thyme or rosemary
Salt and black pepper, to taste
Fresh parsley, chopped (for serving)
Peel the potatoes and cut them into small, even cubes—about 1–1.5cm each—to ensure they roast evenly.
Place the diced potatoes into salted boiling water and cook for 4–5 minutes until just beginning to soften. Drain well and allow the steam to evaporate.
Heat your oven to 200°C (fan 180°C). A hot oven ensures crisp browning.
Transfer the potatoes to a large bowl. Add olive oil or melted butter, crushed garlic, herbs, salt, and pepper. Toss gently until every cube is coated.
Arrange the cubes in a single, spaced-out layer on the baking tray so they roast instead of steam.
Bake for 25–35 minutes, turning occasionally, until the potatoes are crisp, golden, and aromatic.
Sprinkle with fresh parsley and serve warm as a perfect side dish.
