Quarter or eighth of the potatoes and place in a large, flat, oven-safe dish. Add the remaining ingredients and distribute them so that the potatoes are covered with them. First drizzle the potatoes with the lemon juice and then immediately with the olive oil.
Bake in the hot oven on the top shelf without a lid for about 1 hour until they are light brown, crispy on the outside and soft on the inside. While cooking, stir the potatoes every now and then and add water if necessary.
