This is a pumpkin soup with a lot more going on than the usual version. Lemongrass, ginger, makrut lime leaves and coriander root all go in early to build a proper Thai-style base before the pumpkin and coconut milk bring it together.

Don’t skip sautéing the coriander root — it’s got way more flavour packed into it than the leaves, and it’s what gives this soup its depth. Let the pumpkin go completely soft before you blend it too, or you’ll end up with a grainy texture instead of silky smooth.

Finish it with a swirl of coconut milk, some fresh chilli and coriander, and a slice of toasted bread on the side. Proper comfort food with a bit more character than your standard pumpkin soup.

Why You'll Love This Thai Pumpkin Soup

Pumpkin Soup With Actual Depth of Flavour

Lemongrass, ginger, lime leaves and coriander root all get sautéed before the pumpkin even goes in, so the aromatics have time to properly infuse the whole pot rather than just sitting on top.

Coconut milk brings the richness and rounds off the spice and citrus notes, giving it that classic Thai balance of creamy, tangy and a little bit of heat from the chilli garnish.

It also freezes really well, which not every soup does once you add coconut milk, so it's a great one to batch cook and keep on hand.

Ingredients

Soup

  • 22.5 ml Olive Oil
  • 2 Red Onions Chopped
  • 3 Garlic Cloves Chopped
  • 2 Stalks Lemongrass Bruised
  • 25 g Coriander (Cilantro), Leaves, Stems & Roots Chopped
  • 25 g Ginger Peeled & Grated
  • 1.2 kg Butternut Pumpkin Squash
  • 4 Lime Leaves
  • 1 Litre Vegetable Stock
  • 400 ml Coconut Milk
  • Salt & Pepper To Taste

Garnish & Serving

  • 1 Long Red Chilli Sliced
  • Coriander (Cilantro)
  • Coconut Milk Swirl
  • Bread To Toasted

Method

  • Place a large pot over high heat. Add the olive oil, then the onion, garlic and ginger, and sauté for 2 minutes. Add the lemongrass and coriander root, and sauté for a further 2 minutes.
  • Add the pumpkin and lime leaves, season to taste, and sauté for 5 minutes to soften the pumpkin, stirring regularly.
  • Add the vegetable stock, give it a mix through, bring to a boil, reduce the heat to low, and simmer for 25-30 minutes or until the pumpkin is completely soft.
  • Remove from the heat and allow to cool if you're using a blender or food processor. If using an immersion blender, just turn off the heat — no need to wait for it to cool down. Add the chopped coriander leaves and stems, and blend until everything is completely smooth, scraping down the sides if necessary.
  • Place the pot back over low heat, pour in the coconut milk, season to taste, and serve with the garnishes and toasted bread. Dig in.
Chef's Tips
Don't skip sautéing the coriander root — it carries a lot more flavour than the leaves and is a real backbone of the soup's aroma, so give it the full 2 minutes to soften and release its oils.
Let the pumpkin simmer until it's completely soft before blending — any firm pieces left behind will leave the soup with a grainy rather than silky texture.
Blend thoroughly and scrape down the sides as you go — this is what gets the soup properly smooth rather than leaving small unblended chunks.
Storage & Reheating
Will keep in the fridge for up to 4 days in an airtight container, or in the freezer for up to 3 months — coconut milk-based soups hold up well to freezing, though a good stir once reheated will help bring the sauce back together. Reheat gently in a pot over low-medium heat, or in the microwave, until piping hot.

Common Questions
Do I need to remove the lemongrass and lime leaves before blending?
Yes, definitely fish these out before you blend. They've done their job flavouring the soup by this point, and blending them in will leave the soup fibrous instead of silky smooth.
Can I use a stick blender instead of a jug blender?
Yes, and it's actually easier — you can blend straight in the pot without waiting for it to cool. If you're using a jug blender or food processor, let the soup cool a bit first so you're not dealing with hot liquid under pressure.
Where do I find makrut lime leaves?
Most Asian grocers stock them fresh or frozen. If you can't find them, a strip of lime zest is a reasonable substitute, though the flavour won't be quite as distinct.
Can I freeze this soup?
Yes, it freezes well for up to 3 months since coconut milk-based soups generally hold up better than cream-based ones. Give it a good stir once reheated to bring everything back together.
