Yes, you can easily make a vegan version of this dressing by swapping out the dairy ingredients for vegan alternatives. Use vegan mayonnaise in place of regular mayonnaise, and substitute the Parmesan cheese with a dairy-free cheese or nutritional yeast to achieve a cheesy flavor. For the buttermilk, use plant-based milk (like almond, soy, or oat milk) with a bit of lemon juice or apple cider vinegar to mimic the acidity. This way, you can enjoy a creamy, flavorful dressing without any animal products.
