Put all of the ingredients, except the parmesan cheese, into a blender or food processor.
Blend for about 30-45 seconds or until smooth and creamy. If you find that the dressing is a bit thick for your liking, you can add a little more water to thin it out to your preferred consistency.
Once it's creamy add the Parmesan cheese and pulse a few times just to incorporate it. This keeps the dressing creamy while still giving you that classic cheesy flavor and a little texture from the Parmesan. If you prefer it ultra-smooth, you can blend the Parmesan in with everything else from the beginning—but traditionally, pulsing it in at the end gives the best flavor and consistency.
Adjust the seasonings to taste. Feel free to add more lemon juice for extra tang, more garlic cloves if you’re a garlic lover (guilty!), or a pinch of salt if you think it needs it.
Serve and enjoy!
Notes
This dressing will keep in the fridge for up to 5 days.
Store in an airtight container, like a mason jar.
The recipe takes about 5 minutes to throw together if you already have hardboiled eggs on hand. If not, then add about 10 minutes for cook time.
