Preheat oven to 425℉. Line a baking sheet with parchment paper, or lightly grease, and set aside.
Clean potatoes and optionally peel off skins. Slice into about 1 inch cubes.
Add cubed potatoes to a bowl. Top with olive oil, salt, Italian seasoning, garlic powder, and pepper. Toss to evenly coat potatoes. Pour potatoes out onto prepared baking sheet and spread into a single layer.
Roast potatoes in the oven for about 30 to 35 minutes, or until potatoes are evenly browned and can easily be pierced through with a fork. Flip halfway through with a spatula to ensure even browning.
Remove from oven, optionally top with grated parmesan cheese, and serve immediately.
