Ingredients

Gather these simple ingredients to create your delicious kabocha squash soup. Fresh kabocha, rich butter, savory broth, and creamy dairy form the heartwarming base.

• ½ onion
• 1.4 lb kabocha squash
• 1 Tbsp unsalted butter
• 2 cups chicken stock/broth (use vegetable broth for vegetarian)
• 1½ cups milk (whole milk recommended)
• ½ cup heavy (whipping) cream
• 2 tsp Diamond Crystal kosher salt
• ⅛ tsp freshly ground black pepper
• parsley (chopped, for garnish)

Notes & Substitutions

Kabocha squash boasts a firm texture and a naturally sweet, nutty flavor, often compared to a cross between a sweet potato and pumpkin. If you can’t find kabocha, butternut squash or sugar pumpkin make excellent substitutes, though the flavor profile will vary slightly. For a vegetarian or vegan version, always choose vegetable broth. You can also swap dairy milk and cream for full-fat coconut milk or cashew cream to keep it dairy-free. Feel free to adjust the salt and pepper to your taste, adding more if desired, and consider a pinch of nutmeg for extra warmth.

Instructions

Prepare a wonderfully smooth and flavorful kabocha squash soup by following these easy, step-by-step instructions.

Prepare Ingredients

1. First, gather all the ingredients listed. This ensures a smooth cooking process.
2. Thinly slice ½ onion. Set it aside for now.
3. Carefully handle the 1.4 lb kabocha squash. Use a spoon to scoop out and discard the seeds. Cut the squash into 6 thin wedges.
   • Tip: For step-by-step instructions and a video tutorial on how to safely cut and peel kabocha, refer to a dedicated guide on cutting squash.
4. Remove the tough skin from each kabocha wedge. Then, cut the peeled squash into small, equal-sized cubes. This promotes even cooking.

Cook the Soup Base

1. In a large pot or Dutch oven, heat 1 Tbsp unsalted butter over medium heat. Add the sliced onion and cook until it becomes soft and translucent, about 5-7 minutes.
2. Add the cubed kabocha to the pot. Sauté for a few minutes, stirring to coat the squash cubes evenly with the melted butter and sautéed onions.
3. Pour in 2 cups of chicken stock or vegetable broth. Bring the liquid to a boil.
4. Once boiling, reduce the heat to low, cover the pot, and simmer for 12–15 minutes. Cook until the kabocha is very tender.
5. To check for tenderness, insert a skewer or fork into a kabocha cube. It should slide in easily with no resistance.

Blend and Finish

1. Carefully puree the soup until it’s completely smooth. You can do this in batches using a standard blender (be cautious with hot liquids and vent the lid) or directly in the pot with an immersion blender.
2. Return the pureed soup to the pot if you used a standard blender.
3. Stir in 1½ cups of milk and ½ cup of heavy (whipping) cream. Mix until thoroughly combined and the soup reaches a uniform consistency.
4. Gently heat the soup over moderately low heat. Do not let the soup boil after adding the dairy, as it can curdle.
5. Season the soup with 2 tsp Diamond Crystal kosher salt and ⅛ tsp freshly ground black pepper. Stir well. Continue to heat gently until the soup is hot and ready to serve.

Serve

1. Ladle the warm kabocha squash soup into individual bowls.
2. Garnish each serving with a sprinkle of fresh chopped parsley for a pop of color and freshness. Serve immediately and enjoy!

Pro Tips & Troubleshooting

• Selecting Kabocha: Choose a kabocha that feels heavy for its size and has a firm, deep green skin. Avoid soft spots or blemishes.
• Cutting Kabocha Safely: Use a very sharp, heavy chef’s knife. Slice the squash in half first, then scoop out seeds. For stubborn squash, microwave it for 1-2 minutes to soften the skin slightly before cutting.
• Achieving Creaminess: Blend the soup thoroughly. If using a standard blender, process in small batches for the smoothest result. An immersion blender offers convenience directly in the pot.
• Flavor Adjustments: Taste the soup before serving. If it needs more sweetness, a touch of maple syrup or brown sugar can enhance the kabocha squash soup flavor. Add more salt or pepper gradually if desired.
• Preventing Boiling: Dairy can curdle when boiled. Always heat gently over low to moderate heat, stirring frequently, once milk and cream are added.
• Common Mistakes: Avoid undercooking the kabocha, which results in a lumpy soup. Also, don’t forget to season; proper seasoning elevates all the natural flavors.

When cooking kabocha squash, various methods can be used to bring out its natural sweetness, including roasting, steaming, and slow cooking, each offering a unique texture and flavor profile. Discover more about different methods to cook kabocha squash.

• Herbaceous: Incorporate fresh sprigs of thyme or rosemary while simmering the kabocha for an earthy depth of flavor. Remove before blending.
