1) Preheat the oven to 400 degrees F.
2) Cut the potatoes to be about the same size. Place cut potatoes in a bowl with the olive oil, salt, pepper, and garlic; toss until the potatoes are well coated. Pour the potatoes on a sheet pan, spreading them out over the pan in a single layer.
3) Roast in the oven for about 30 -50 minutes (depends on the size you cut them) or until browned and crisp. Flip with a spatula once during cooking for even browning.
4) Remove the potatoes from the oven, season to taste, and serve hot.
