Preheat the waffle iron on medium-high heat for about 5 minutes.

In a large mixing bowl, combine the thawed shredded hash browns, shredded cheese, and seasoned salt. Mix until well combined.

Spray the waffle iron with pan release spray.

Scoop about 1 cup of the mixture onto the preheated waffle iron, covering the surface evenly.

Close the waffle iron and cook for 5 to 7 minutes or until golden brown.

Carefully remove the chaffle and allow it to cool slightly on a wire rack.
