This is one of my favorite ways to cook little potatoes. Start with a bunch of salt and pour it into a baking dish then place potatoes on top. After baking, the potatoes taste perfectly seasoned and have a extraordinarily smooth consistency inside. Make these for a simple side dish or serve as finger food next to your favorite dip. And if you were wondering, you can reuse the salt, just save it in a re-sealable plastic bag for the next time you want to roast potatoes. Recipe updated, originally posted September 2010. Since posting this in 2010, we have tweaked the recipe to be more clear. – Adam and Joanne Coarse salt, such as Kosher 2Scrub, rinse and pat dry the potatoes. Fill a 2-quart baking dish with enough salt to create a 1/2-inch layer on the bottom of the dish. Place the potatoes, in one layer, on top of the salt. Bake until the potatoes are tender and you can easily pierce them with a fork, 30 to 45 minutes depending on size of the potatoes.
