Kabocha Soup

Kabocha Soup features cubed kabocha squash cooked with onion in butter and simmered in chicken stock until soft. The soup is pureed smooth, then enriched with milk and heavy cream for a velvety texture. Seasoned with kosher salt and fresh black pepper, the soup has a mild, slightly sweet flavor with a creamy consistency, and is garnished with chopped parsley for freshness.

Description

Kabocha Soup focuses on the naturally sweet and nutty flavor of the kabocha squash. The cooking process begins by sautéing sliced onion in unsalted butter until browned and soft, then adding cubed squash to coat in butter. Chicken stock is added, and after boiling, the squash is simmered until tender. The softened squash and onions are pureed to a smooth texture using a blender or immersion blender.

The soup is then enriched by folding in whole milk and heavy cream, creating a creamy and rich finish without boiling afterward to preserve smoothness. Seasoning with kosher salt and freshly ground black pepper balances the sweetness. Chopped parsley garnishes the soup, adding a touch of color and freshness.

This soup can be served warm as an appetizer or light meal. Its smooth texture and mild flavor profile make it approachable and comforting, suited to enjoy in cooler weather or alongside a simple salad or bread. It is a versatile soup that highlights kabocha's seasonal qualities.
