Prepare Pumpkin: Slice the pumpkin into 3cm / 2.25" pieces, remove the skin and seeds, and then cut into smaller 4cm / 1.5" pieces.
Assemble Soup Base: In your cooking pot, combine the prepared pumpkin, onion slices, whole garlic cloves, chosen broth, and water. The pumpkin may peek above the liquid level slightly.
Simmer: Bring the pot to a boil without a lid, then decrease to a fast simmer. Cook until you can easily pierce the pumpkin with a butter knife, about 10 minutes.
Puree: Off the heat, blend the soup directly in the pot with a stick blender until achieving a smooth consistency. If using a traditional blender, transfer in batches, being cautious of the steam.
Final Touches: Add salt and pepper according to your preference. Mix in the cream softly. Remember, do not let the soup boil post-cream addition to avoid separation.
Garnish and Serve: Serve the soup in individual bowls, enhanced with a drizzle of cream and a dash of pepper. Parsley garnishing is optional. Pair with crusty bread for a complete meal.
