Step 1: Place potatoes in a saucepan and cover with water; bring to a boil, reduce heat cover and cook until alomst tender, do not cook until soft, they will cook and soften more in the oven; drain and cool (this may be done a day ahead, refrigerate the potatoes until ready to use).
Step 2: Grease a 13 x 9-inch baking dish. Preheat oven to 350 degrees F.
Step 3: In a large bowl combine the condensed soup with sour cream, melted butter, garlic powder, cayenne and black pepper; mix in 1-1/2 cups shredded cheddar cheese and onions, then gently stir in potatoes. Season with salt.
Step 4: Transfer to baking dish. Sprinkle the top with remaining 1 cup shredded cheddar cheese. Bake for 25-30 minutes or until hot and bubbly.
