1. Place the potatoes into a large pot and cover with salted water; bring to a boil. Cook the potatoes at a boil for 10 minutes; drain. Set potatoes aside to cool. 2. Once potatoes are cool enough to handle, slide the skin from the potatoes and discard; refrigerate peeled potatoes until completely cold, about 1 hour. 3. Preheat an oven to 350 degrees F (175 degrees C). 4. Grease a 9x13-inch baking dish with 1 tablespoon butter. 5. Grate 2 of the potatoes into the bottom of the prepared baking dish. Sprinkle about 1/4 of the minced onion over the layer of potato; season with salt and black pepper. Repeat layering until all ingredients are used and dish is full. 6. Drizzle melted butter, whipping cream, and half and half over the potato mixture; season with paprika. 7. Bake in the preheated oven until the top is bubbling, about 30 minutes. 8. Garnish with chopped fresh parsley to serve. ---------------------------------------------------------------------------
