Preheat oven to 425 degrees. Line the baking pan with parchment paper if desired. Cut the baby potatoes in half.
In a medium size bowl, mix together the potatoes, olive oil, rosemary, garlic powder, salt and pepper. Lay in a single layer on the baking pan.
Roast for 30 minutes, turning once in the middle of cooking. Potatoes will be done when they are golden brown with a crispy texture but tender when poked with a fork. Season with extra salt, if needed.
