Blend Ingredients. In a high-speed blender, combine the cottage cheese, sweetener, vanilla extract, and salt. Blend until smooth and creamy.
Add Mix-ins. If using, fold in your chosen mix-ins with a spatula.
Freeze. Pour the mixture into a freezer-safe container. For a soft-serve texture, freeze for about 2-3 hours. For firmer ice cream, leave it overnight.
Serve. Scoop and enjoy! If the ice cream is too hard, let it sit at room temperature for a few minutes before serving.
