Add all ingredients except assorted vegetables for dipping to the container of a blender and blend until well-combined and creamy, about 40 seconds. Remove from blender and pour into a 3-cup refrigerator safe container. Chill overnight before serving.
To serve with veggies: pour about 1/4 cup of roasted red pepper buttermilk dip into the bottom of a short glass. Place vegetables into glass for easy serving.
Alternately, pour dip into a large bowl and serve with vegetables.
