Step 1

Place potatoes in a large pot with water. Bruise the rosemary with the dull side of a knife blade and place in the pot. Add garlic, bay leaves, and salt. Bring to a boil; simmer for 5 minutes. Drain; let potatoes air dry.

Step 2

Preheat oven to 375 degrees F (190 degrees C).

Step 3

When potatoes are thoroughly dry, transfer them back to the pot. Drizzle with olive oil, cayenne pepper, and a pinch of salt. Stir to coat. Transfer potatoes to a rimmed sheet pan. Bake until potatoes are golden brown and crusty, and the flesh is creamy and soft, about 35 to 45 minutes, depending on the size of the potatoes.
