In a mixing bowl, combine the garlic, lemon juice, Dijon mustard, sugar, salt, and black pepper.
Whisk these ingredients together until the mixture is smooth and the sugar and salt have dissolved.
Slowly add the olive oil into the bowl.
Whisk constantly to emulsify the mixture.
This is key to achieving a smooth and creamy texture in your vinaigrette.
Fold in the grated Parmesan cheese.
Mix gently until fully integrated and the dressing is an even consistency.
Taste the vinaigrette and adjust seasoning if needed.
A little extra salt and pepper can fine-tune the flavor to your liking.
Transfer your vinaigrette to a sealed jar or airtight container.
Refrigerate for at least 30 minutes to let the flavors meld together.
