Key Ingredients for Authentic Thai Flavor

The magic of this recipe lies in its fresh aromatics. Lemongrass, ginger, turmeric, and lime zest create a vibrant base that infuses the coconut broth with depth. Here’s what you’ll need:

  • 2 tbsp neutral oil (like sunflower or canola)
  • 150g fresh shiitake or chestnut mushrooms
  • 1 tsp sea salt
  • 400ml tin coconut milk
  • 150g thick straight-to-wok udon noodles
  • 2 heads pak choi, finely sliced
  • 150g prawns, peeled and deveined
  • For the base: 1 lemongrass stalk, 2 spring onions, 2 garlic cloves, 1 red chilli, 4cm ginger, 1cm turmeric root, zest and juice of 1 lime

Step-by-Step Cooking Instructions

Prepare the Aromatic Paste

Finely grate all base ingredients (lemongrass, spring onions, garlic, chilli, ginger, turmeric) and mix with lime zest and juice. Alternatively, roughly chop and blitz in a blender until a rough paste forms—just avoid blending whole lemongrass sticks, as they can damage the blender.

Cook the Broth

Heat oil in a large saucepan over medium-low heat. Add the paste and fry for 3 minutes, stirring constantly. Add mushrooms and fry for another 5 minutes. Pour in coconut milk and 400ml just-boiled water, then bring to a boil. Remove from heat and let cool completely. Chill for at least 2 hours.

Assemble the Noodles

Once chilled, cook your noodles according to package instructions (if not using straight-to-wok). Divide noodles and pak choi into bowls, then pour the cold broth over. Add prawns (if using raw, simmer them in the hot broth for 4 minutes before chilling). Serve with lime wedges.

Prep Time 20 minutes + chilling 20 minutes

Tips for Perfect Results

  • For extra heat, leave the chilli seeds in.
  • Make the broth a day ahead to deepen flavors.
  • Add tofu or chicken for a heartier meal.

Frequently Asked Questions

Can I make this recipe gluten-free?

Yes, simply use rice noodles (flat or vermicelli) instead of udon. Ensure your soy sauce or other condiments are gluten-free if you add them.

How long can I store the chilled broth?

The broth can be stored in an airtight container in the refrigerator for up to 3 days. Keep the noodles separate to avoid sogginess.

Can I use frozen prawns?

Yes, thaw them completely and pat dry before adding to the broth. If using pre-cooked prawns, add them just before serving to avoid overcooking.

Final Thoughts

This Thai-style cold lemongrass coconut prawn noodles recipe is a delightful twist on traditional noodle soups. Its vibrant flavors and easy preparation make it a go-to for busy weeknights or special occasions. Try it today and enjoy a bowl of refreshing, aromatic goodness!
