Preheat your oven to 250C/480F.
Fill a pot with water. Generously salt your water. Bring to a boil.
Put in potatoes and cook until fork tender. Cooking times will vary depending on size of your potatoes.
Drain your potatoes and then let them sit in your strainer for a few minutes to let all the moisture evaporate out. This will yield a crispier potato.
Drizzle a bit of the ghee or oil onto your baking sheet. Season the pan with salt and garlic powder. This will be for the bottom of the potatoes touching the pan.
Lay out your potatoes onto your baking sheet. Leaving space for them to be smashed.
Find something with a flat surface to smash your potatoes with. I use the bottom of a 1 cup measuring cup or you can use the bottom of a glass.
Smash each potatoes. Do not smash to flat or they will fall apart.
Season the top of the potatoes with the rest of your ghee or oil and your salt and garlic powder.
Put into the oven and bake for 20-25 minutes. You can also put them under the broiler for a few minutes at the end if you want them extra crispy. (watch carefully as they could burn quickly)
Season with more salt and/or garlic powder if needed.
