Peel and cut potatoes into fries, and pat dry with a towel to remove excess moisture.

Heat oil in a large pot to 140°C (284°F) and fry the potatoes in batches until golden and crispy.

While fries cook, melt butter in a saucepan over low heat. Add minced garlic, salt, and pepper. Stir until garlic becomes fragrant.

Once fries are cooked, toss them in the garlic butter sauce. Sprinkle with chopped parsley and grated parmesan (optional).

Serve immediately while hot for best flavor.
