Thai Butternut Squash Soup

This Thai-style butternut squash soup, flavored with red curry paste and coconut milk, is as soothing as it is flavorful. The ginger and spices add just the right amount of heat to warm you up, while the toppings—Sriracha, peanuts, scallions, and cilantro—bring vibrant flavor, texture, and a pop of color. For me, this soup is hearty enough to enjoy as a main course, but if you’ve got heartier appetites at the table, a scoop of jasmine rice makes a perfect addition to bulk it up.

What You’ll Need To Make Thai-Inspired Butternut Squash Soup

Soup ingredients including lime, fish sauce, and ginger.
  • Vegetable Oil: Helps sauté the onions, garlic, and ginger, forming a flavorful base for the soup.
  • Onions And Garlic: Provide a savory depth that balances the sweetness of the squash and carrots.
  • Fresh Ginger: Adds a warm, slightly spicy note that complements the curry flavor.
  • Butternut Squash And Carrots: Create the creamy, slightly sweet body of the soup.
  • Chicken Broth: Forms the liquid base, adding depth and richness.
  • Fish Sauce: Enhances the umami element of the soup, adding a subtle savory note and authentic Thai flavor.
  • Sugar: Balances the subtle heat of the curry paste with a hint of sweetness.
  • Thai Red Curry Paste: Infuses the soup with a bold flavor. Red curry paste is generally not very spicy, but the flavor profile can vary between brands.
  • Unsweetened Coconut Milk: Adds creaminess and a slight sweetness that tempers the spice.
  • Lime Juice: Provides a bright, tangy contrast to the rich, creamy soup.
  • Sriracha, Scallions, Peanuts, and Cilantro: Optional garnishes that add texture and additional layers of flavor to the finished dish.

Ingredients 

For the Soup

  • 3 cloves garlic, very roughly chopped
  • 2 tablespoons roughly chopped fresh ginger, from a 2-inch (5-cm) knob (see note)
  • lb pre-cut butternut squash or one 3-lb (1.3-kg) butternut squash, peeled, seeded and cubed
  • 3 large carrots, cut into 1-inch cubes
  • 6 cups chicken broth

  • 3 tablespoons sugar
  • 2 to 3 tablespoons Thai red curry paste

  • ¼ teaspoon salt

Optional Garnishes

  • Sriracha sauce, for drizzling
  • 4 scallions, thinly sliced
  • ¾ cup salted peanuts, roughly chopped
  • cup chopped fresh cilantro

Instructions

  • Heat the oil in a large soup pot over medium heat. Add the onion, garlic, and ginger and cook, stirring frequently, until softened, 6 to 8 minutes. Do not brown; reduce heat if necessary.
  • Add the squash, carrots, broth, fish sauce, sugar, and 2 tablespoons of the curry paste. Bring to a boil, then lower the heat and simmer, covered, until the vegetables are tender, about 20 minutes.
  • Using a hand-held immersion blender, purée the soup until silky smooth. (Alternatively, cool the soup slightly, then purée in a blender in batches, making sure to leave the hole in the lid open to allow the steam to escape.) Stir in the coconut milk, lime juice, and salt (if the coconut milk is solidified, use the immersion blender to mix it in).

Drizzle with the Sriracha and garnish with the scallions, peanuts, and cilantro, if using.

Notes

Make-Ahead/Freezer-Friendly Instructions: This soup can be made up to 3 days ahead of time and stored in a covered container in the refrigerator. Keep in mind that the soup will thicken up quite a bit as it cools, so you'll need to add a bit of water or broth to thin it back to the right consistency upon reheating. The soup can also be frozen for up to 3 months. Defrost the soup in the refrigerator overnight and then reheat it on the stovetop over medium heat until hot, thinning with water or broth if necessary.

    So delicious! I was planning on freezing some but this is not going to last past a couple of days.

    Wonderful soup!! I used a little more ginger than recipe called for (personal preference). I added the carrots and softened with onions by accident but it worked out fine. Used 1 1/2T of red curry powder. I will make this again and again. Thanks Jenn!

  • Approximately how many cups of butternut squash does this call for? Mine is already cut up.

    • Hi Margie, I’d guesstimate it’s about 4 cups give or take. Hope you enjoy!

  • Hi Jenn,
    I love all your recipes! Is there any substitute for fish sauce? I am vegetarian so want to skip it.
    Thanks,
    SK

    • Hi SK, you could substitute soy sauce for the fish sauce. It won’t have that same authentic Thai flavor without the fish sauce, but it will still be good. Enjoy!

      • Sounds good. Thank you!!

    This is a nutrient and flavor packed soup! I had an odd winter squash that I got in the misfit section at the market for cheap (misshapen and lumpy buttercup, I believe) that I halved, oiled, and baked cut side down until soft. This make scooping seeds, and scraping out the flesh super easy. Don’t skip the fish sauce if you’re on the fence as it really lends an authentic flavor, as does the cilantro, lime, and chopped peanut to finish it.

    OMG the soup is so good. Delicious, omitted the fish sauce (did not have) and cut down to 1 tablespoon of sugar. Jenn, you are a truly amazing chef.

    This is great soup! Easy and full of flavor. I made a batch and froze it in 3-cup containers. Perfect reheated, as well.

    Love love love this soup! I was craving fall flavors and decided to make this dish today, even though it’s a warm, late summer day; something about the spices and Thai flavors just worked with the weather!

  • Hi Jenn, love your recipes! I don’t have a lime would lemon be a food substitute or nothing? Thanks, Sabrina

    • Hi Sabrina, so glad you like the recipes! I think you could get away with using lemon here. Hope you enjoy. 🙂
