How to Make Vegan Japanese Winter Squash and Leek Soup Directions
To make your Vegan Japanese Winter Squash and Leek Soup, you can follow these simple steps that will lead you to a warm and comforting bowl of goodness.
First, begin by preheating your oven to 350 degrees F (175 degrees C). Once preheated, arrange your halved kabocha squash cut-side up on a clean baking sheet. Bake the squash in the oven until tender, which typically takes about 30 to 40 minutes. Once cooked, allow the squash to cool slightly before handling it. You can then remove the skin and chop the flesh into bite-sized pieces.
While the squash is baking, heat the canola oil in a large pot over medium heat. Add the chopped sweet onion and the white parts of the leeks, stirring frequently. You want to cook these until they are soft and golden brown, which should take about 10 to 15 minutes.
Next, it’s time to add the remaining vegetables. Mix in the chopped russet potatoes, round cuts of carrots, and the previously prepared kabocha squash to the pot with the onion and leeks. Pour in the 2 cups of water (adding more as necessary) and bring the mixture to a boil. Reduce the heat, cover your pot, and let it simmer. Stir the soup every 10 minutes, monitoring the consistency and adding more water if needed. Continue this process until the vegetables are tender, which takes about 1 hour.
After the vegetables are softened, pour the vegetable stock into the mixture. This will enhance the flavor profile and create a more robust taste. Season the soup with a pinch of garlic salt and a dash of ground black pepper, adjusting to your personal preference. Increase the temperature to medium and allow it to boil gently for another 15 to 20 minutes. At this point, your Vegan Japanese Winter Squash and Leek Soup should be ready to enjoy!

Expert Tips: Vegan Japanese Winter Squash and Leek Soup
