Boil: Add 3–4 Yukon Gold potatoes to a pot of well-salted water and boil until fork-tender, then drain and let cool completely.
Preheat: Heat a mini waffle maker and lightly grease with olive oil or avocado oil spray.
Flatten: Place 1 small potato into the waffle maker and gently flatten with a fork or spoon.
Season: Sprinkle generously with finely grated Parmesan, then close the waffle maker.
Cook: Cook for 7–8 minutes until deeply golden and crisp on both sides.
Repeat: Continue with remaining potatoes, greasing the waffle maker as needed.
Serve: Top with Greek yogurt or sour cream, shredded cheddar, crispy bacon, and green onion, then finish with salt and black pepper.

Notes
Some people have told me they've had to let their waffle cook for 15-12 minutes! It totally depends on the heat of your waffle maker. Patience is key here. :)
Letting the potatoes cool fully is key for crispiness.
Finely grated Parmesan melts and crisps better than shredded.
These are best served hot, straight from the waffle maker.
