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

In a large mixing bowl, combine thawed frozen hash browns or freshly grated potatoes with shredded cheese and seasoned salt; mix thoroughly.

Spray the heated waffle iron with pan release spray to prevent sticking.

Spoon approximately 1 cup of the hashbrown mixture into the center of the waffle iron, spreading it out gently.

Close the waffle iron and cook for about 5-7 minutes until golden-brown and crispy.

Once cooked, remove the chaffle and let it cool on a wire rack for a moment before serving.
