01 - Place the red potatoes in a large pot and cover with cold, salted water. Bring to a boil and cook for 10-12 minutes, or until just fork-tender. Do not overcook.
02 - Drain the potatoes and spread them out on a baking sheet to cool slightly.
03 - In a large bowl, whisk together the mayonnaise, Dijon mustard, apple cider vinegar, salt, pepper, garlic powder, and smoked paprika.
04 - Add the cooled potatoes, celery, red onion, parsley, and dill to the bowl with the dressing. Gently toss to coat all ingredients evenly.
05 - Taste and adjust seasoning if needed. Refrigerate for at least 1 hour before serving to allow flavors to meld.
06 - Garnish with additional parsley or dill before serving, if desired.
