In a mixing bowl, combine the sour cream, mayonnaise, and buttermilk.
Add the Ranch Seasoning mix to the bowl and whisk until well combined.
Taste the dressing and season with salt, if desired.
If the dressing is too thick, you can add more buttermilk to reach your desired consistency.
Once seasoned to your liking, transfer the ranch dressing to a jar or airtight container.
Refrigerate the dressing for at least 30 minutes before serving to allow the flavors to meld together.
Give the dressing a good stir before serving, and enjoy it drizzled over salads, as a dip for veggies, or as a topping for your favorite dishes.
