Preheat oven to 200-220 Celsius degrees.
Place both halves of the pumpkin (cut side down) on a baking tray, lined with baking paper. You might need to use two baking trays in the pumpkin is too big. Sprinkle the pumpkin with a little bit of salt and grease it with olive oil.
Place the pumpkin in the oven and roast it for 30 minutes or until it becomes fork-tender. Remove from the oven and let it cool down.
Once cooled down enough that you can handle the pumpkin with your hands, add it to a large bowl. Add spices, sea salt, and gluten-free flour. With your hands, knead the dough. If it seems to be too sticky, add a little bit more flour. Make little gnocchi. In batches, add them to a saucepan with boiling water with a little bit of sea salt. Cook the gnocchi for about 2 minutes. Reserve 1/2 cup water from cooking (for sauce).
Now when gnocchi is cooked, heat olive oil in a pan and add gnocchi (in batches). Fry them from each side for about 2 minutes until they become slightly golden.
Make the sauce: In a frying pan, add vegan butter, sage leaves, and crushed garlic. Cook for 2-3 minutes. Remove from heat and add reserved 1/2 water from cooking. Whisk together. Toss pumpkin gnocchi in the sage sauce.
Sprinkle with dairy-free parmesan cheese and chopped fresh parsley. Enjoy!
