Crispy outside, fluffy inside, and enough garlic to keep vampires out of your entire neighborhood. These are the potatoes people hover over the pan for before they even make it to the table. The secret is a hot oven, dry potatoes, and absolutely not skimping on the garlic.
Preheat your oven to 425°F (220°C). Place a heavy rimmed baking sheet in the oven while it preheats — a hot pan is essential for getting a crispy bottom on the potatoes.
Wash 2 pounds of potatoes well. Yukon Golds are the best choice here — they have a creamy, buttery texture and their skins crisp up beautifully. Cut them into roughly 1 to 1½ inch cubes. Try to keep them uniform.
Place the cut potatoes in a large pot and cover with cold, salted water by at least an inch. Bring to a boil and par-boil for 5 to 6 minutes. You're not cooking them through — just starting the process so the outside gets fluffy and the inside cooks fully in the oven.
Drain the potatoes and return them to the hot pot. Let them steam-dry for 1 to 2 minutes. Then shake the pot vigorously several times — this roughs up the outside surface of the potatoes, creating more surface area for crisping.
Toss the roughed-up potatoes with 3 tablespoons of olive oil, 6 to 8 minced garlic cloves, 1 teaspoon of salt, ½ teaspoon of black pepper, and 1 teaspoon of fresh or dried rosemary.
Carefully pull the hot baking sheet from the oven and immediately spread the seasoned potatoes on it in a single layer. You should hear a satisfying sizzle when they hit the pan.
Roast for 20 minutes without disturbing them. This allows a crust to form on the bottom — if you move them too early, you'll tear the crust off.
Flip each potato with a spatula and roast for another 12 to 15 minutes until golden, crispy, and cooked through. A fork should slide in with no resistance.
Optional but excellent: sprinkle with fresh grated parmesan in the last 3 minutes of cooking for a salty, savory crust.
Remove from the oven and taste immediately — adjust salt if needed. Transfer to a serving dish and eat them while they're hot. Cold roasted potatoes are fine. Hot crispy roasted potatoes are transcendent.
