Combine Ingredients: In a medium-sized mixing bowl, add the mayonnaise, buttermilk, ranch seasoning packets, and salt.
Mix Thoroughly: Using a whisk or spoon, stir the ingredients together until fully combined. Ensure there are no clumps of seasoning remaining and the mixture is smooth and uniform in texture.
Refrigerate: Transfer the mixture to an airtight container or cover the bowl with plastic wrap. Place it in the refrigerator to chill for at least 1 hour. This step allows the flavors to meld and the dressing to achieve its signature creamy consistency.
Serve: Once chilled, remove the ranch dressing from the refrigerator. Stir briefly before serving to ensure an even texture. Use it as a dip, dressing, or sauce according to your preference.
