Place the potatoes in a large pot of cold, salted water. Bring to a boil and cook for 20-25 minutes, until the potatoes are fork tender (medium potatoes may need longer). Tip into a colander to drain and set aside to steam dry for a few minutes.
1 kg small potatoes
Preheat the oven to 200°C.
While the potatoes are steam drying, add the butter and oil to a cast iron skillet or oven-proof dish and place it in the oven to melt the butter.
50 g salted butter, 1 tablespoon olive oil
When the butter is melted, remove the skillet from the oven and tip in the potatoes. Using a potato masher, or the bottom of a glass or measuring cup, gently smash the potatoes – enough to burst the skin and create knobbly ridges, but not hard enough to mash the potatoes.
Gently move the potatoes about so they’re covered in butter and bake for 25-30 minutes, giving them a shake every now and then, until golden and crispy all over.
While the potatoes are baking, gather and finely chop the herbs. To the herbs add the garlic and chilli and chop through everything again. Zest over the lemon rind and set aside.
½ cup mixed fresh herbs*, 2 garlic cloves, 1 long red chilli, Zest from 1 lemon
In the last 10 minutes of baking, gently stir in the herbs, garlic, chilli and lemon zest to the potatoes.
Serve hot, sprinkled with feta.
60 g feta
