Wash and slice the potatoes directly into a bowl of water. Drain and pat dry with paper towels.
For the cheese sauce, finely chop the garlic cloves and parsley and set aside.
Heat a medium saucepan and melt the butter. Mix in the flour and combine. Add in the milk and cook until thickened.
Grate the cheese into the thickened milk sauce and add in the chopped garlic and parsley and mix till combined. Season with salt and pepper to taste.
For the chips, combine the garlic powder, salt and pepper and set aside.
Heat up the oil (3 cups) in a pot. Once hot, fry the chips until golden brown in color. Remove from the oil and drain on a paper towel. Immediately season with the garlic salt seasoning.
Once all the chips are fried, serve in a bowl and sprinkle with parsley alongside a small bowl of the cheese sauce.
