Preheat oven to 180C/350F.
Peel your butternut pumpkin (or pumpkin variety of your choice) and chopped into equal-sized chunks.
In a baking tray, add the pumpkin chunks, onion, garlic, thyme and rosemary. Drizzle generously with olive oil and season with salt & pepper. Bake for 1 hour or until the veggies are soft and slightly browned.
In a pot, melt the butter and add in the miso. Break up the miso in the butter and toast for ~1-2 mins or until it's fragrant. Add in the roasted veggies, stock and water. Mix well to dissolve the miso.
Transfer the soup into a blender, or you can also use a stick blender like me, and blend until the soup is nice and smooth. Optional but you can add in 1/2 cup of heavy cream, mix well. Here you can adjust the consistency of your soup by adding more water if desired and season to taste.
Toast some bread into butter. Garnish soup with a drizzle of heavy cream, olive oil and a dash of parsley. Serve warm with bread.
