Preheat your grill to 400 degrees and wash your potatoes.
Once the potatoes have been washed, cut them into sticks by cutting the potato in 4 or 5 vertical pieces 1/4″ thick, and then cut each piece into sticks.
Place cut fries into a bowl of cold water and let soak for 20 minutes.
After 20 minutes, drain the potatoes and dry them thoroughly
Add the potatoes to a dry bowl, add olive oil and Weber’s Garlic Parmesan seasoning, and toss.
Cook fries on preheated grill for 25-30 mins or until the desired doneness.
