Preheat your waffle iron to medium-high heat and wait for the indicator light to signal it's ready.

Grate fresh potatoes or thaw and pat dry frozen hash browns to ensure they are moisture-free.

Combine hash browns, shredded cheese, and seasoned salt in a mixing bowl until evenly distributed.

Lightly spray or brush both waffle plates of the preheated waffle iron with cooking spray or oil.

Scoop about 1 cup of the hash brown mixture into the center of the waffle iron without overfilling.

Cook until golden brown and crispy, typically 4-6 minutes, and wait an additional 30-45 seconds for extra crispiness.

Carefully remove chaffles and place them on a wire rack if not serving immediately to prevent sogginess.
