In a medium bowl, combine mayonnaise, sour cream, and buttermilk, stirring until smooth and well blended.
Add the chives, dill, and parsley to the mixture, ensuring each herb is finely chopped to distribute the flavors evenly.
Incorporate the minced garlic, onion powder, salt, black pepper, and paprika. Stir everything together well to achieve a uniform blend of all the ingredients.
Stir in the lemon juice; this will not only add a hint of freshness but also help balance the richness of the mayonnaise and sour cream.
Once all ingredients are mixed, taste and adjust seasoning if necessary.
Transfer the dressing to an airtight container and refrigerate for at least one hour, allowing the flavors to meld beautifully.
