Crisp Roasted Potatoes From Cook's Illustrated.Published November 1, 2009. http://www.cooksillustrated.com/recipes/detail.asp?docid=20855 4/3/2010 Serves 4 to 6. The steps of parcooking the potatoes before roasting and tossing the potatoes with salt and oil until they are coated with starch are the keys to developing a crisp exterior and creamy interior. The potatoes should be just undercooked when they are removed from the boiling water. Ingredients 2 1/2 lb Yukon Gold potatoes , rinsed and cut into 1/2-inch-thick slices Table salt (easy on the salt!) 5 tbsp olive oil Ground black pepper * Adjust oven rack to lowest position, place rimmed baking sheet on rack, and heat oven to 450 degrees. * Place potatoes and 1 tablespoon salt in Dutch oven; add cold water to cover by 1 inch. * Bring to boil over high heat; * reduce heat and gently simmer until exteriors of potatoes have softened but centers offer resistance when pierced with paring knife, about 5 minutes. * Drain potatoes well and transfer to large bowl. * Drizzle with 2 tablespoons oil and sprinkle with 1/2 teaspoon salt; using rubber spatula, toss to combine. * Drizzle with another 2 tablespoons oil and 1/2 teaspoon salt; continue to toss until exteriors of potato slices are coated with starchy paste, 1 to 2 minutes. * Working quickly, remove baking sheet from oven and drizzle remaining tablespoon oil over surface. * Carefully transfer potatoes to baking sheet and spread into even layer (skin-side up if end piece). * Bake until bottoms of potatoes are golden brown and crisp, 15-25 minutes, rotating baking sheet after 10 minutes. * Remove baking sheet from oven and, using metal spatula and tongs, loosen potatoes from pan, carefully flipping each slice. * Continue to roast until second side is golden and crisp, 10 to 20 minutes longer, rotating pan as needed to ensure potatoes brown evenly. * Season with salt and pepper to taste and serve immediately.
