Whisk together the 1 cup mayonnaise, ½ cup sour cream, and ½ cup buttermilk in a medium bowl for about 1 minute until completely smooth.

Add the 1 tsp dried dill, 1 tsp dried parsley, ½ tsp dried chives, ½ tsp garlic powder, ½ tsp onion powder, ¼ tsp smoked paprika, ½ tsp kosher salt, and ¼ tsp black pepper. Whisk for 1 minute until fully blended.

Transfer to a lidded jar and refrigerate for at least 30 minutes. Taste and adjust salt or thin with up to 2 tbsp more buttermilk if needed.

Stir or shake the jar, pour into a serving bowl, and finish with a pinch of dried dill and cracked black pepper on top.
