Preheat oven to 400 degrees F.
In a small bowl combine olive oil, lemon juice and garlic. Mix well. Pour over cooked potatoes. Toss until coated well. Bring a large saucepan of salted water to a boil. Place potatoes in the saucepan and continue boiling for about 8 to 10 minutes. You do not want them completely cooked. You are parboiling them, so you should be able to pierce them with a fork but they should not be completely tender. Drain and transfer to a large bowl.

Place pan in preheated oven and bake for 10 to 15 minutes, flipping halfway through the cooking process. Potatoes are done when evenly brown and crispy on edges. If you like yours super crispy you can cook them for 3 to 5 minutes longer under your broiler.
