Laksa is a spicy noodle soup popular in the Peranakan cuisine of Southeast Asia. Laksa consists of thick wheat noodles or rice vermicelli with chicken, prawn or fish, served in spicy soup based on either rich and spicy curry coconut milk or on sour asam. Laksa is found in Indonesia, Malaysia, Singapore, and southern Thailand.


Also, according to Wiki, the word laksa comes from an ancient Persian word for “noodles”. So the name of this recipe is essentially King Prawn Noodles Noodles! Oh well!

This recipe is from one of Slimming World’s frozen meals – that no longer seems to be available, so I guess it’s a good thing I have the recipe to share with you!

The recipe starts by making a laksa sauce using onion, butternut squash, garlic, ginger, curry powder, kaffir lime leaves, lemongrass, fish stock cube, fresh coriander, soy sauce, and fish sauce.

King prawns, veggies, and noodles are then stir-fried with the sauce, and some fat-free Greek yogurt is stirred through to add a creamy touch.

If you enjoy trying to flavour combinations, this King Prawn Laska Noodles dish is definitely one to try!
