First line a tray with tinfoil and preheat the oven to 400 degrees.
Wash and thoroughly dry the potatoes.
Place the potatoes on the tinfoil lined tray making sure to not overcrowd the tray. You will probably need two trays.
Drizzle 2 tablespoons of sesame oil, 1 tablespoons of salt, 1 tablespoon of garlic powder and ½ tablespoon of ground ginger onto the tray.
Stir the potatoes so that everything is evenly coated.
Bake the tray of potatoes in the oven at 400 degrees for 25 minutes, or until the potatoes are fork tender.
After the potatoes are fork tender, take the tray out of the oven.
Carefully, with a potato masher or the bottom of a pot, smash the potatoes down. You want the potatoes smashed to about a ¼-½ inch thickness.
Then, drizzle or brush the remaining tablespoon of sesame oil over the smashed potatoes.
Top with the remaining tablespoon of salt.
Place the tray back in the oven for about 10 minutes or until the potatoes are getting lightly golden brown on the bottom.
Serve and enjoy!
