Ingredients

Why this recipe works

The slow cooker method is ideal for squash because it allows the tough fibers to break down slowly, resulting in a naturally creamy texture without needing added thickeners or dairy. This gentle heat preserves the bright color of the red kuri squash while intensifying its nutty, sweet undertones.

By keeping the cooking process contained, all the aromatic compounds remain in the pot, leading to a much more fragrant and flavorful final soup compared to stovetop boiling methods.

Chestnuts add a distinct earthy, slightly sweet flavor that pairs beautifully with the squash. When cooked slowly in the liquid, they soften and blend effortlessly into the soup, providing a silky mouthfeel and a layer of complexity that is difficult to achieve with squash alone.

The vegetable bouillon acts as a savory foundation, balancing the natural sweetness of the squash and chestnuts, ensuring the final dish is well-rounded and deeply satisfying.

Notes and substitutions

Red kuri squash is prized for its thin, edible skin and bright orange flesh, which becomes very smooth when pureed. If you cannot find red kuri, butternut squash is an excellent alternative, though you will need to peel it thoroughly as the skin is thicker and tougher. Ensure your chestnuts are pre-cooked, as raw chestnuts require a different preparation method and significantly more time to soften.

A high-quality vegetable bouillon cube is essential for this recipe as it serves as the primary seasoning. If you prefer a more robust flavor, you can replace the bouillon and water with a high-quality vegetable or chicken stock.

Always use an immersion blender for the safest and most efficient way to puree the soup directly in the slow cooker, avoiding the need to transfer hot liquids to a separate blender.
