Wash your potatoes.
Cut the potatoes in half, then make six lengthwise cuts in each half. Depending on how thick those potato slices are, you may need to cut those in half as well to make them fry size.
Fill a large bowl with water. Add one tablespoon of sugar. Soak the French fries in water for at least 30 minutes.
Drain and rinse the French fries. Pat them dry with a paper towel.
Drizzle them with olive oil, garlic powder, and salt (plus any additional spices you might prefer). Toss to coat.
Heat the side burner of your grill to high.
Put the French fries in a grill safe pan.
Add about a half inch of olive oil to the pan. Toss the French fries in the oil.
Put the pan on the side burner and cook about 15 minutes on one side, then flip for another 15 minutes. Cooking about 30-35 minutes total until well browned.
Remove from grill. Place on a paper towel-lined bowl and sprinkle with coarse salt.
