Preheat oven to 325°. Line a baking sheet with parchment paper. To prepare the potatoes, scrub, rinse and dry thoroughly. Transfer them to the baking sheet and toss with extra virgin olive oil.
Bake potatoes on the middle rack in preheated oven for 1 hour.
While the potatoes bake, make the seasoning blend. In a small bowl, stir together dill, parsley, garlic powder, onion powder, pepper and sea salt. To add a zesty "cheesy" flavor to the potatoes, also stir in nutritional yeast. Otherwise, leave it out.
After an hour of baking, remove the potatoes from the oven and preheat the broiler. Sprinkle the potatoes with the seasoning blend and gently toss to coat the potatoes evenly with seasonings.
Evenly distribute the potatoes on the baking sheet. Use the back of a wooden spoon, the side of a heavy mug or the bottom of a sturdy bowl to smash each potato until they're about ¼ inch thick.
Return the smashed potatoes to the oven under the broil and broil until the edges are golden and crisp (10 to 20 minutes).
If using, drizzle finished potatoes with melted ghee before serving. These potatoes are best served immediately when they're warm and crispy.
