I am always trying to find new and different ways to cook the same kind of foods. When my daughter saw and tasted these potatoes for the first time, she ate half the pan! I knew we had a winner and I let her take the remainning potatoes home with her (after I had tried at least one!)
Preheat oven to 375 degrees. Peel and wash potatoes. Bring large pot(with lid) of water to boil. Place potatoes in boiling water. When the water returns to a boil, boil 5 minutes. Drain potatoes then return them to same pot. Add butter, put lid on pot and shake vigorously 1-2 minutes.
Coat bottom of roasting pan with small amount of olive oil. Transfer potatoes to roasting pan. Sprinkle each potato with coarse salt. Place in oven, uncovered 40-45 minutes, turning halfway through. After the 45 minutes, turn oven up to 425 degrees, return potatoes to oven 5 minutes to brown.
