Preheat the oven to 200 degrees Celsius - 392 F
Mix the oil, salt, and spices in a small bowl.
Brush a baking tray with olive oil and sprinkle salt, pepper, and dried thyme..
Using a sharp knife, cut the potatoes lengthwise into thin slices as much as possible without reaching the bottom - leave about half a centimeter.
Arrange the potatoes on the tray with the cut side up. Generously brush the potatoes with the oil mixture, dip the brush in the oil accumulated on the tray, and brush the potatoes again.
Cover with baking paper, place aluminum foil sheets over the paper, and close from the sides. Bake in the center of the oven for 45 minutes. Remove the baking paper and aluminum and continue to bake until the potatoes brown nicely—about twenty minutes.
Transfer to a serving plate, sprinkle parsley leaves, and serve with a salad.
