Preheat your waffle maker to a medium-high to high setting, ideally between 4 to 6 if using a Cuisinart. Allow about 5 minutes for the waffle maker to reach the ideal temperature.

Peel and shred the 2½ pounds of yellow potatoes using a box grater or food processor and squeeze out excess liquid to prevent sogginess.

In a large mixing bowl, combine the shredded potatoes with 1 cup of grated Gruyere cheese, 1 small grated onion, 1 whisked egg, 2 tablespoons of rice flour, 1 teaspoon of salt, and ½ teaspoon of ground black pepper. Stir thoroughly.

Lightly brush the preheated waffle maker with 1 tablespoon of avocado oil, spread about 1 cup of the batter evenly onto the hot plates, close the lid, and cook for 6 to 8 minutes or until golden brown.

Carefully remove the waffles from the waffle maker and serve them hot with toppings like sour cream, ketchup, apple sauce, or a refreshing avocado dip.
