Thinly slice the onion.
Add the pumpkin, onion, and milk to a pot and simmer over medium-low heat for 15 minutes.
Once the ingredients are soft, blend them smoothly with a hand blender.
Add fresh cream and salt, then simmer on low heat for 5 more minutes.
Serve in a bowl, drizzle with a little olive oil, and sprinkle parsley to finish.
