Boil potatoes. Drain water. In a bowl, add the potatoes and garlic cloves and mash. Keep potatoes a little chunky to add texture. Season with salt and pepper.
Heat the vegetable oil on medium heat in a frying pan. Cook the shallots until translucent, about 5 minutes. Add the shallots to the smashed potatoes. Add the smashed potatoes to a pan, sprinkle with salt and pepper and fry.
Using a spatula flip the potatoes constantly to allow them to crisp up and turn golden brown, about 5 minutes.
