Preheat oven to 425 degrees.
Cut pumpkin into quarters. Rub with grapeseed oil and place on pan cut side down. Cook for 20 minutes.
Flip to other cut side and cook for another 20 min.
Remove pumpkin from oven and let cool.
Add vegetable stock, salt, and pepper to a pot and bring to a simmer.
Once cooled, scoop out cooked pumpkin, measuring 4 cups. Reserve the skins for homemade vegetable stock, for a treat for your chickens, or compost. Add pumpkin to a blender along with 4 cups of coconut milk or another plant-based milk of choice.
Blend on high for a few seconds until smooth. (If there's too much liquid for your blender, do in batches.)
Transfer contents back to a pot, stir to incorporate into broth, add kidney beans (optional), and reheat if necessary.
Garnish with fresh parsley and toasted pumpkin seeds.
