To store the gnocchi: Freeze cooled gnocchi on baking sheets. When frozen, transfer the gnocchi to an airtight container and freeze until ready to use. Gnocchi can be frozen for 1 to 2 months. This makes A LOT of gnocchi. You can easily cut this recipe in half if needed. I like to make a lot so I can make 2 to 3 meals with them. This dish is intended to be eaten as a vegan dish, but you most certainly can add Parmesan cheese to it.
