Place cut up rutabaga into a medium saucepan. Add 1/2 teaspoon of the salt and enough water to just cover. Bring to a boil over high heat. Reduce heat to medium-low and simmer until soft, about 20 minutes. Drain.
While the rutabaga cooks, cook the minced bacon over medium heat until crisp, about 8-10 minutes. Do not discard the grease.
Using a food processor or potato masher, mash the drained rutabaga, remaining 1/2 teaspoon of salt, 1/2 teaspoon freshly ground black pepper, and bacon grease together until smooth. Stir in the cooked bacon and 1 Tablespoon minced fresh parsley. Serve hot.
