Put potatoes in a large pot and cover with water. Place on stove over medium-high heat and let boil for 45 minutes. Drain in colander and transfer to mixing bowl. Allow to cool to room temperature (approximately 2 hours, 4 hours is better, 8 hours is best).
In a mason jar, combine oil, vinegar, hot honey, dijon mustard, salt, pepper and dill. Secure lid and shake vigorously.
Once cooled, cut each potato in half and return to mixing bowl. Add onions and dressing. Gently toss to coat. Serve right away or store in airtight container for up to 3 days.
