Cook 2 pounds chopped peeled Yukon Gold potatoes in simmering salted water until just tender, about 5 minutes; drain well. Toss with 1/4 cup olive oil, 1 tablespoon chopped rosemary, 1 teaspoon kosher salt and a few grinds of pepper. Roast on a preheated baking sheet at 475 degrees F, stirring halfway, until crisp, about 40 minutes. Sprinkle with salt and serve with garlic mayonnaise.
