1 cup mayonnaise
1/2 cup buttermilk
1/4 cup sour cream
1 garlic clove, minced
1 tbsp chopped fresh parsley
1 tbsp chopped fresh chives
1 tsp dried dill
1/2 tsp onion powder
1/2 tsp salt
1/4 tsp black pepper

In a medium mixing bowl, whisk together the mayonnaise, buttermilk, and sour cream until smooth.
Add the minced garlic, chopped parsley, chopped chives, dried dill, onion powder, salt, and black pepper to the bowl. Whisk everything together until well combined.
Taste the dressing and adjust the seasoning as needed with additional salt or pepper.
If the dressing is too thick, you can thin it out with a little more buttermilk or water. If it’s too thin, you can add more mayonnaise.
Transfer the dressing to a jar or container with a tight-fitting lid. Chill the dressing in the refrigerator for at least 30 minutes before serving to allow the flavors to meld together.
Serve the buttermilk ranch dressing with your favorite salad, vegetables, or as a dip for chicken wings or other snacks. Store any leftover dressing in an airtight container in the refrigerator for up to 1 week.
