Preheat oven to 400°F (200°C) and line a large baking sheet with parchment paper or a silicone baking mat.
Place the riced cauliflower in a clean kitchen towel and squeeze firmly to remove as much moisture as possible.
In a medium mixing bowl, combine the dried cauliflower rice, cottage cheese, beaten eggs, Parmesan cheese, garlic powder, salt, and pepper.
Stir the mixture until the ingredients are fully incorporated and a thick batter forms.
Scoop approximately 1/4 cup of the mixture onto the prepared baking sheet for each thin.
Use the back of a spoon to flatten and shape each scoop into a 4-inch circle, approximately 1/4 inch thick.
Bake for 22 to 25 minutes, or until the edges are golden brown and the thins feel firm to the touch.
Remove from the oven and allow to cool on the baking sheet for at least 5 minutes to set before serving.
