Soften cream cheese, and stir in yogurt, sour cream, and lemon juice. Mix until thoroughly combined.
Add the remaining ingredients, except the salmon. Make sure everything is blended. Add the flaked smoked salmon last.
Serve smoked salmon dip on bagels, with crackers, bagel chips, or sliced carrots, cucumbers, and celery.
Notes
If you prefer your dip to have a creamy texture, pulse the ingredients in a food processor. If you want the end result chunkier, blend the mixture by hand.
Store leftover dip in an airtight container in the refrigerator for up to a week.
