Peel the potatoes. Cut off any “eyes” or other undesirable spots. Place in a large pot and cover with water, bringing the water about 2 cm above the potatoes. Salt the water. Bring to a boil. Simmer the potatoes until fork-tender, about 15-20 minutes, depending on the size of your potatoes. And when ready, pour off the water and let them cool a bit.
Meanwhile, mix the herb and butter/oil. Combine all ingredients in a small bowl, grease an oven form and grate the parmesan.
Preheat oven to 200°C, Just to keep it warm, we're going to use the grill later on.
When potatoes are cool enough to handle, transfer them to an oven form, use a fork or similar to "smash" them. Drizzle the herb mix on top and season with salt flakes. Spread the parmesan evenly over the form.
Turn the grill element in the oven to high and put in the potatoes. Check from time to time, around 10 min is usually a normal time, or until they start to look brown. Take potatoes out of the oven. Now you'll have a perfect side dish. Cuisine - The joy of food
