Peel the potatoes if desired. I like to leave the peel on for additional texture. Chop the potatoes into 1-inch cubes.
Add the potatoes to a large pot and cover with cold water. (Optional: Add 2 teaspoons of salt to the water to add flavor right into the potatoes.) Bring to a boil until potatoes are tender (about 6-8 minutes)
Drain the potatoes. Let cool for 30 minutes.
In the meantime, whisk together the remaining ingredients (mayo, celery, red onion, relish, vinegar, dijon, onion powder, garlic powder, dill, paprika, pepper, and salt.)
Add potatoes into a large bowl and gently stir in the mayo mixture. Add salt to taste.
