Place carrots into a skillet; add 1-inch of water, and bring to a boil. Reduce heat; cover, and cook 8-10 minutes or until crisp-tender. Drain, and set aside.
Add butter, brown sugar and ranch dressing mix to the same skillet, and mix until blended. Stir carrots back in.
Cook and stir over medium heat 5 minutes or until glazed. Sprinkle with parsley, if desired.
