Preheat the oven to 400°F.
Wash the potatoes thoroughly. Halve small potatoes and quarter larger potatoes.
Place the potatoes on a baking sheet and drizzle with olive oil.
Season with kosher salt and freshly ground black pepper.
Add the finely chopped garlic and toss everything together until evenly coated.
Spread the potatoes into a single layer, keeping some space between the pieces.
Roast for about 30 minutes, or until the potatoes are golden and crisp outside and tender inside.
Remove from the oven and sprinkle with fresh chopped parsley.
Serve hot.
