Slow Cooker Red Kuri Squash and Chestnut Soup Step-by-step instructions

Before you start

Before beginning, ensure all ingredients are ready for assembly. Wash the exterior of the red kuri squash thoroughly, then carefully peel and cube it into one-inch pieces to ensure even cooking.

Measure the chestnuts and set aside. Have the bouillon cube ready to crumble and ensure the water is hot before pouring it into the slow cooker to speed up the initial heating phase of the recipe.

Instructions

Preparation and assembly

1. 1Assemble ingredients
   Place the peeled and cubed red kuri squash into the bottom of the slow cooker. Scatter the whole cooked chestnuts over the squash, then crumble the vegetable bouillon cube evenly over the top.
   Look for Ensure the squash is cut into uniform pieces for even cooking throughout the process.
   Tip Removing the skin from the red kuri squash is easier if you use a sharp vegetable peeler.

At this stage, the slow cooker contains the raw squash, chestnuts, and crumbled bouillon.

The ingredients are layered to ensure the bouillon disperses evenly as the water is poured in. Everything should look neat and ready for the long, slow cooking process to begin.

Slow cooking phase

2. 2Add liquid and cook
   Pour the hot water over the contents of the slow cooker. Cover with the lid and cook on the low setting for approximately 4 hours, or until the squash is completely tender and breaks apart easily with a fork.
   Look for The squash should be fork-tender and the liquid should be simmering gently.
   Tip Using hot water instead of cold water helps the slow cooker reach the target temperature faster.

The soup has been cooking for several hours. The kitchen should smell fragrant and earthy. Check that the squash is soft and the liquid has taken on the color of the squash. The mixture is ready for blending once the squash collapses under light pressure.

Blending and finishing

3. 3Blend and serve
   Once the cooking time is complete, use an immersion blender to process the soup directly in the slow cooker until smooth and velvety. If the consistency is too thick, add a small amount of additional hot water until the desired texture is reached.
   Look for The soup should be glossy and completely smooth with no remaining large chunks of squash or chestnut.
   Tip If you do not have an immersion blender, transfer the soup to a standard blender in batches, taking care when blending hot liquids.

After blending, the soup should be perfectly smooth, glossy, and uniform in color. It should be thick enough to coat the back of a spoon. Check the seasoning and texture one last time before serving, ensuring it is piping hot and ready to be enjoyed.

Common mistakes

A common mistake is cutting the squash into uneven or overly large pieces, which can lead to some parts being mushy while others remain raw. Ensure all pieces are roughly the same size.

Another error is using too much water, which can result in a thin, watery soup. Start with the suggested amount of water and only add more after blending if the soup is thicker than your preference.

How to tell it’s done

The soup is done when the squash cubes are completely tender and can be easily mashed with a fork against the side of the slow cooker.

The liquid should be well-incorporated with the squash, and the chestnuts should be soft enough to blend completely into a silky, smooth consistency. There should be no resistant chunks remaining when you run the immersion blender through the mixture.
