Pre-heat the oven to 400°F
First, thoroughly clean and peel the potatoes.
Peel the potatoes. Then, cut the ends of the potatoes. Cut the potato lengthwise into 1/4 - 3/8 inch slices. Do not cut larger than 1/2 inch. Larger slices are harder to manipulate and also do not get as crispy when baked.
Place the potato horizontally. Place the skewer on both sides of the potato. Use skewers as a base and cut vertical lines.
Flip the potato over and cut diagonal lines.
Push the skewer through the potato. Gently stretch out the potato, starting with the bottom and work towards the middle.
While you are slicing the potatoes, keep the potatoes that you have already cut in cold water. This helps to keep the potatoes from turning brown. This also helps to break down the excess starch which will help make delicious crispy potatoes when they are baked.
Arrange the potato skewers on a parchment-lined baking sheet. Brush the garlic-herb butter onto both sides of the potatoes.
Place the potatoes in the oven for 30-40 minutes, flipping gently halfway through. Once they are done the potatoes will have crispy edges and a golden brown center.
Allow the potato skewers to cool for 5 minutes. Add your favorite toppings and enjoy!
