Preheat the oven to 350° F.
Wash potatoes and place them into a 9x13 baking dish.
Cover with foil and bake for 1 hour and 15 minutes or until the potatoes are tender.
Once the potatoes are done, remove the foil and leave them to cool.
After the potatoes are cool enough to handle, cut in half and scoop out the inside, add the flesh to a medium sized mixing bowl and set aside.
In a large skillet, add oil, potato skins, chopped onion, minced garlic, salt and pepper.
Cook over medium high heat, until the potato skins become crispy brown, set aside.
Next add the plant based milk and garlic to the potato flesh and mash until smooth.
Spread the mashed potatoes into the bottom of the 9x13 baking dish.
If adding a cheese, sprinkle or pour over the potatoes.
Pour the potato skins over the mashed potatoes.
Add more cheese over the dish before covering.
Cover with foil and bake for 40 minutes.
After 40 minutes, remove the foil and return to the oven for another 5 minutes.
Remove from the oven and serve hot.
Garnish with an aioli or a vegan sour cream and fresh herbs.
