All my years living and working in Thailand, this is still my favourite dish called ‘Khao Soi’. It’s mostly available in northern Thailand and Burma, so it’s quite difficult to find in good ‘Khao Soi’ Banagkok because it's classed as a seasonal dish. But I thought I would bring a low FODMAP version to your homes. The ingredients are pretty easy to find and you should be able to pick most of them up at your local asian grocery store.
It’s a mild spice traditionally, but if you like it hot you can adjust the temperature by the amount of red curry paste you add. It has a rich, thick, creamy texture.
Peel and dice the potatoes (about 2cm squares) and chop the carrot into half moons. De-skin the garlic cloves and shallots (keep them whole if low FODMAP) . In a deep saucepan fry the potatoes, garlic, carrot, and shallots with the curry powder for 3 minutes (stir continuously making sure the veggies are coated in the curry powder).
Now add the coconut milk, curry paste, chicken broth, bring to a boil (stir continuously).
Now add the chicken and bring the curry to a light simmer and cook for 30 minuets. While waiting soften the noodles by placing them in a large bowl emerging them in cool/warm water (not hot) for 15 -20 minuets.
By now the noodles should be soft so place them in serving bowls. Make sure the chicken is cooked all the way through; if it's ok place the chicken onto of the noodles and then pour the curry soup over the noodles making sure to get the vegetables (Low FODMAPers, avoid the shallots and garlic)
