Start by combining the mayonnaise and buttermilk in a mixing bowl. Use a whisk to blend them until the mixture is smooth and free of any lumps. This creamy base is the foundation of your dressing, so make sure it’s well mixed!
Next, add the dried parsley, dill weed, garlic powder, onion powder, dried chives, salt, and black pepper to the bowl. Stir thoroughly until the herbs and spices are evenly distributed throughout the mixture. The blend of these seasonings is what gives Mazzio’s Ranch Dressing its signature flavor.
Transfer the dressing into an airtight container or jar. Place it in the refrigerator for about 30 minutes. Allowing the dressing to chill is crucial, as it lets the flavors meld together, resulting in a rich, tangy taste that’s just like Mazzio’s.
