Enjoy a creamy Kabocha squash soup in the slow cooker! This easy, healthy, and vegan squash soup recipe is perfect for a cozy fall meal.

A black bowl filled with orange pumpkin soup, garnished with a swirl of cream and a sprig of fresh thyme, sits on a black saucer. A silver spoon rests in the bowl. A gray cloth napkin is in the background on a marble surface.

This is the perfect soup recipe for the Fall season! Nothing beats a warm, smooth, and creamy bowl of soup after a long, tiring day. 

This velvety Kabocha squash soup is sweet and nutty because of the squash's natural flavor, but it's also savory thanks to the sautéed garlic and onions. You can customize it all you want, make it as peppery as you wish.

With the slow cooker, you can pop all the ingredients in, set it for 6-8 hours (3-4 if you don't have that long), and go about your day. You'll have time to spend with the kids, do some chores, go out for a quick errand, read a book, whatever you want! You have free time with this recipe. 

I like preparing this recipe because my kids love it. They enjoy how creamy it is, and it's a win for me that they're eating squash without even realizing it. It's a great way to sneak in some extra vegetables!

The slow cooking process allows the flavors to meld and intensify, resulting in a rich, comforting soup with minimal effort. This hands-off approach is perfect for busy days when you want a nutritious meal but don't have time to stand over the stove. And the slow cooker is not just for soup, I use it to make the most delicious slow cooker greek chicken, gingerbread oatmeal, and even gingerbread fudge.

Ingredients

A whole green squash is centered on a marble surface surrounded by a glass bottle of oil, a whole onion, two garlic cloves, a small bowl of cream, and a lid with pepper and spices.

Kabocha squash, peeled and cubed - it's best to use fresh Kabocha for this, but you can you use frozen squash if you can find it.
Onion, chopped - adds a savory base flavor
Garlic cloves, minced - provides aromatic, pungent taste
Vegetable broth - creates soup base and adds depth of flavor
Cream (optional) - enriches texture and flavor. Use coconut cream for a vegan kabocha squash soup.
Olive oil - used for sautéing and adds richness
Black pepper - adds mild heat and enhances overall flavor
Non-stick cooking spray - helps prevent sticking during cooking

Prepare the Base

A person stirs chopped onions in a pot with a wooden spoon on a marble countertop. Nearby are a small dish with pepper, an oil bottle, and a plate.

Heat oil in a large pan over medium heat. Add the chopped onion and minced garlic to the pan. Sauté these ingredients for about 5 minutes, stirring occasionally, until they become soft and translucent. This process helps to release their flavors and create a savory base for your soup.

Transfer to Slow Cooker

A black slow cooker on a marble countertop contains sautéed onions with a wooden spoon resting inside. Nearby are a small bowl of salt and pepper, a bottle of oil, and a small plate.

Once the onion and garlic are softened, transfer them to your slow cooker. Be sure to scrape all the flavorful bits from the pan into the slow cooker as well.

Add Remaining Ingredients

A glass of amber-colored liquid is placed in the center of a marble countertop. Nearby, there is a metal lid with some white and black specks, a wooden bowl, and a small bottle of olive oil. A spoon rests in a small dish.

Slow Cook

A black slow cooker filled with orange-colored soup containing visible potato chunks. The cooker is placed on a white marble surface. The ingredients appear to be simmering in a savory broth.

Cover the slow cooker with its lid. If you're planning to cook it throughout the day or even overnight, set it to low and let it cook for 6-8 hours. If you're short on time, you can set it to high and cook for 3-4 hours. The soup is ready when the squash is very tender and easily mashed with a fork.

Blend the Soup

A black slow cooker filled with creamy orange soup is shown from above. An immersion blender is partially submerged in the soup, indicating it is being blended. The slow cooker is placed on a white marble surface.

Once the cooking time is complete, it's time to puree the soup. If you have an immersion blender, you can blend the soup directly in the slow cooker until it's smooth. If using a regular blender, carefully transfer the soup in batches and blend until smooth, then return it to the slow cooker.

Final Touches

A hand pours cream from a small pitcher into a slow cooker filled with orange soup, while another hand stirs with a wooden spoon. The scene is set on a white surface, and a colorful bracelet is visible on one wrist.

If you're using cream, stir it into the pureed soup now. This will give the soup a richer, creamier texture. Taste the soup and adjust the seasoning if needed, adding more salt or pepper to your preference.

Serve

Bowls of orange soup with cream swirl and herbs are on a marble surface. A pot with more soup and a ladle is nearby. Silver spoons are in the bowls, and sprigs of thyme are scattered around. Gray napkins are placed to the side.

Your kabocha squash soup is now ready to serve. Ladle it into bowls and serve hot. You can garnish with a drizzle of cream, some fresh herbs, or toasted pumpkin seeds if desired.

Storage

Two black bowls of pumpkin soup sit on a white marble surface. Each bowl has a swirl of cream on top and a sprig of thyme. Spoons rest in both bowls, and a few thyme sprigs are scattered nearby.

To store Kabocha Squash Soup, allow the soup to cool to room temperature before transferring it to an airtight container. For optimal freshness, refrigerate the soup for up to 4-5 days. If you want to freeze it, portion the soup into freezer-safe bags or containers, removing as much air as possible to prevent freezer burn. Frozen soup can be stored for up to 3 months. To reheat, thaw frozen soup in the refrigerator overnight. Then, heat the soup in a pot over medium heat, stirring occasionally, until it reaches a simmer and is heated through. You can also use a microwave, heating in 1-minute intervals, stirring between each interval, until warm. If the soup has thickened after storage, you can thin it with a little broth or water while reheating. If you added cream to the soup before storing, it may separate slightly when reheated; simply whisk it well to recombine.

Top Tips

Roast the squash for extra flavor: Before adding the kabocha squash to the soup, consider roasting it in the oven. Cut the squash into cubes, toss with olive oil, and roast at 400°F (200°C) for about 25-30 minutes.

Use an immersion blender for ease and safety: Be careful when blending hot liquids to avoid splatters. If the soup is too thick after blending, gradually add more broth to reach your desired consistency. If you don't have an immersion blender, let the soup cool slightly before transferring it in batches to a regular blender.

Garnish for added texture: While the soup is deliciously creamy on its own, adding a garnish can elevate the dish. Try toasted pumpkin seeds, a swirl of cream, or a sprinkle of crispy bacon bits for contrasting texture and additional flavor.

What to Serve with Slow Cooker Kabocha Squash Soup

This slow cooker kabocha squash soup pairs well with my no knead Italian rosemary sourdough bread (vegan). The bread's texture and rosemary flavor complement the soup's creamy consistency and subtle sweetness.

For a complete meal with varied textures, try serving this soup alongside my Middle Eastern quinoa salad recipe. The quinoa and vegetables provide a nice contrast to the smooth soup. Any grain-based side dish works well with this soup, offering a satisfying meal with different textures and flavors.

If you're looking for more recipes to pair with this soup, consider exploring other grain salads or crusty bread options to find your preferred combination.
