Instructions

1. 1

   Soften the aromatics

   Heat the oil in a soup pot over medium heat. Add the onion, chilli and a pinch of salt; sauté for 8–10 minutes, until softened. Stir in the ginger and garlic for about 30 seconds, until fragrant. Add the kaffir lime leaves, if using, the lime zest, vegetable broth and water. Cover and bring to the boil.

2. 2

   Simmer the vegetables

   Add the sweet potato, squash or carrots and the shiitake mushrooms. Bring the soup back to a simmer, cover and cook for 10–15 minutes, until the vegetables are cooked through. Stir in the sugar and coconut milk, bring back to the boil, then turn off the heat. Mix in the lime juice, discard the kaffir lime leaves if using, and taste for salt, adding more if needed.

3. 3

   Cook and serve

   Cook the noodles according to the packet instructions and divide them between bowls. Ladle the broth over the noodles, including some vegetables and mushrooms in each serving. Finish generously with green onion, cilantro, lime slices, crushed nuts and chilli flakes, if using.

What is coconut noodle soup?

Coconut noodle soup is a broad style of noodle dish rather than one fixed recipe, combining noodles with a coconut-enriched broth and aromatic seasonings. This plant-based version brings together ginger, garlic, chilli and lime with vegetables and shiitake mushrooms.

The creamy coconut milk balances the sharp citrus and warming aromatics, while rice noodles make it a filling bowl. Lime leaves add an especially fragrant note, though the soup still works without them.

Nutrition and macros by portion

The nutrition label shows one serving as written: 623 calories, 9g protein, 78g carbs, 31g fat.

The rice noodles and sweet potato, squash or carrots provide most of the carbohydrates; coconut milk and oil contribute most of the fat. The mushrooms and vegetables add some protein, but this soup is not especially protein-rich, so serve it with edamame or tofu if you want a more balanced plate.

Build the aromatic base

Softened onion: Give it the full 8–10 minutes over medium heat so it turns tender before the liquid goes in.

Ginger and garlic: Add these after the onion and stir for about 30 seconds; they need only a brief cook to release their fragrance without scorching.

Chilli: Remove the seeds if you prefer a milder broth, or leave some in for more heat.

Make the broth fragrant

Lime leaves: Add them with the broth so their citrus aroma has time to infuse. Remove them before serving, as they are there to flavour the soup rather than to eat.

Lime zest: The ingredient list calls for lime zest, which gives the broth a bright citrus aroma. Add the lime juice after switching off the heat to keep its flavour fresh.

Choose and cook the vegetables

Sweet potato or squash: Cut it into medium chunks so the pieces become tender during the 10–15-minute simmer without disappearing into the broth.

Carrots: Two medium carrots offer an alternative to the sweet potato or squash; cut them into similar-sized chunks for even cooking.

Shiitake mushrooms: Stem and slice them before adding. Simmer until the vegetables are cooked through and the mushrooms are tender.

Keep the noodles springy

Cook the noodles separately according to their packet instructions, rather than simmering them in the soup. This helps prevent them from soaking up too much broth or becoming over-soft.

Divide the noodles between bowls first, then ladle the hot broth and vegetables over them. If preparing bowls at different times, keep the noodles and soup apart until serving.

Finish with balance

Coconut milk: Full-fat coconut milk gives the broth its creamy body. Bring the soup back to the boil after adding it, then turn off the heat and stir in the lime juice.

Toppings: Green onion, cilantro and lime slices add freshness, while crushed cashews or peanuts bring crunch. Chilli flakes are optional if you want extra heat.

What to serve alongside

The noodles, vegetables and coconut broth make this a complete-feeling bowl on their own. For a fresh contrast, serve with extra lime wedges or a crisp green salad.

Offer the nuts and chilli flakes at the table so everyone can choose their own finishing touches.

Recipe notes & tips

• Cut the chosen root vegetable into evenly sized chunks so they cook at the same rate.
• Use the lower end of the chilli amount by removing the seeds if you want a gentler broth.
• Taste the broth for salt after adding the coconut milk and lime juice.
• Keep noodles separate from the broth until serving, especially if making bowls ahead.
• Put extra lime, herbs, nuts and chilli flakes on the table for people to add as they like.

Variations

• Add tofu: Stir in cubes of firm tofu with the vegetables so they warm through in the broth.
• Use carrots: Swap in two medium carrots for the sweet potato or winter squash.
• Try other noodles: Use another noodle of your choice and cook it according to its packet instructions.
• Make it spicier: Add extra chilli flakes at the table or leave the chilli seeds in.
• Skip the nuts: Leave out the cashews or peanuts for a nut-free bowl.

Common mistakes to avoid

• Rushing the onion: It may stay firm; sauté it for the full 8–10 minutes until softened.
• Scorching the garlic: It can turn bitter; stir it with the ginger for only about 30 seconds.
• Overcooking the vegetables: They can become too soft; check them after 10 minutes of simmering.
• Leaving lime leaves in: They are tough to eat; remove them before serving.
• Cooking noodles in the soup: They can soak up the broth and turn soft; cook them separately and assemble each bowl.

How to store

Store leftover broth and noodles separately in airtight containers in the fridge for up to 3 days. Reheat the broth gently in a saucepan until hot, and cook fresh noodles or briefly warm the stored noodles separately before serving.
