Description

Transport your taste buds to the tropics with this creamy Coconut Lime Fish Soup 🌴🥥 — bright lime, fragrant herbs and tender fish in every spoonful. Perfect for a light, exotic dinner! 🐟🍋

 

Ingredients

– 1 tbsp vegetable oil 🥥

– 1 small red onion, thinly sliced 🧅

– 2 cloves garlic, minced 🧄

– 1 tbsp fresh ginger, grated 🫚

– 2 stalks lemongrass, smashed and sliced (white part only) 🍃

– 400 ml (1 can) coconut milk 🥥

– 500 ml fish stock or low-sodium chicken broth 🐟

– 400 g white fish fillets (cod, snapper or halibut), cut into chunks 🐟

– 150 g mushrooms, sliced (shiitake or button) 🍄

– 2–3 small red chilies, sliced (or 1 tsp chili flakes) 🌶️

– 3 tbsp fish sauce 🐠

– 2 tbsp fresh lime juice (about 1–2 limes) 🍋

– 1 tsp palm sugar or brown sugar 🍯

– A handful fresh cilantro (coriander), chopped 🌿

– Salt 🧂 and freshly ground black pepper

– Cooked jasmine rice or rice noodles to serve 🍚

Instructions

1 Prepare aromatics: thinly slice the onion, mince the garlic, grate the ginger and smash the lemongrass stalks, then slice the tender white parts.

2 Heat the vegetable oil in a large pot over medium heat. Add the onion and sauté until translucent, about 3–4 minutes.

3 Add garlic, ginger and lemongrass to the pot and cook for 1–2 minutes until fragrant.

4 Pour in the coconut milk and fish stock. Bring the mixture to a gentle simmer and let it infuse for 8–10 minutes so the aromatics release their flavor.

5 Add the sliced mushrooms and chilies, simmer for another 3–4 minutes until the mushrooms are tender.

6 Gently add the fish chunks to the simmering soup. Poach the fish for 4–6 minutes, depending on thickness, until it is opaque and flakes easily.

7 Season the soup with fish sauce, lime juice and palm sugar. Taste and adjust balance — add more fish sauce for saltiness, more lime for brightness, or a pinch more sugar if needed.

8 Remove lemongrass pieces before serving if large. Stir in chopped cilantro and season with salt and pepper to taste.

9 Serve hot over steamed jasmine rice or with a portion of rice noodles. Garnish with extra cilantro and a wedge of lime if desired.

What Makes This Soup Special?

The magic of Coconut Lime Fish Soup lies in its balance:

  • Coconut milk adds creaminess and subtle sweetness
