In a large Dutch oven, combine potatoes, parsnips, rutabaga, onion, and 2 tablespoons salt; add water to cover. Bring to a boil over high heat; reduce heat to medium-low and simmer for 10 to 12 minutes or until tender. Drain well. Add remaining salt, cream cheese, butter, and a dash of pepper. Mash together.
