Set the oven to 390°F and peel the potatoes. Chop them into evenly sized pieces for uniform roasting.

Place potatoes in a large pot filled with water, add 4 sprigs of rosemary and a pinch of salt. Bring to a boil and parboil for 12 minutes until a knife slides through with slight resistance.

Pour 2 to 3 tablespoons of olive oil into a large baking dish and place in the oven to heat until very hot to ensure crispy potatoes.

Drizzle remaining olive oil evenly over the potatoes, season generously with salt, then roast in the oven for 45 minutes.
