Since mastering my low FODMAP Thai red curry paste, I’ve been sneaking it into as many recipes as possible. This low FODMAP Thai noodle soup may be one of my favourite creations so far!

The secret to this soup is caramelized leeks. To do this, spread your leeks out over the bottom of your heated stock pot and let them hang out for a bit. They’ll start to brown and take on a deep,  savoury flavour. Just remember to give them a swirl now and then, so they don’t burn.

This soup is fantastic hot or cold, so it’s currently my number one lunch recommendation! Grab your favourite mason jar and brace your taste buds, friend. This soup will rock your socks!

Keep It FODMAP Friendly

Looking for a tasty lunch you can take to work? This low FODMAP Thai noodle soup is the lunch to beat! Check out the notes below for tips on keeping this recipe FODMAP friendly.

First up, chicken. Since chicken is a protein, it doesn’t have any FODMAPs. That means you can eat as much as you’d like without adding to your FODMAP load.

This soup gets its rich underlying flavour from garlic-infused oil. Don’t panic, though! FODMAPs are water-soluble (meaning they break apart in water) but not fat-soluble. That means when you cook a FODMAP in fats like butter or oil, the fat will absorb the oil, but not the FODMAPs.

When choosing a low FODMAP garlic-infused oil, check the label for ingredients like “garlic extract,” or “natural flavours,” as these may indicate there are actual garlic pieces in the oil. You should also check the bottle for visible pieces of garlic and sediment in the bottle. If you’re worried about dipping your toe into infused oils, try this garlic-infused oil by Fody Foods Co. This product is certified by Monash University, so it’s 100% low FODMAP.

We’ll also be using red bell peppers. Monash recently updated the low FODMAP serving of red bell peppers. They used to be listed as “eat freely,” meaning you could have as much as you’d like without adding anything to your FODMAP load.

According to the Monash update, red bell peppers are low FODMAP in servings of 1/3 of a cup (43 g) per sitting. Servings of 1/4 pepper (57 g) or more are now high in the FODMAP fructose.

We’ll be using 1 cup of bell peppers in this recipe, which works out to 13 g per serving. This is well within Monash’s new recommended range.

This recipe also uses Thai red curry paste. If you don’t have a curry paste recipe handy, you can grab mine here. Because we’re only using 3 tbsp of curry paste for 8 servings, this won’t add a noticeable serving of FODMAPs to our recipe.

We’ll also be using coconut milk. According to Monash, coconut milk is low FODMAP in servings of 1/4 cup (60 g) per serving. Servings of 1/2 a cup (120 g) or more are high in the FODMAP sorbitol. We’ll be using 1 400 ml can of coconut milk which works out to 50 g per serving. This is within Monash’s recommended range.

We’ll also be using fresh basil. Monash University has said fresh basil is low FODMAP in servings of 1 cup per sitting though they don’t mention a limit.

The same goes for rice noodles. According to the Monash app, rice noodles are low FODMAP in servings of 1 cup per sitting. But Monash hasn’t listed a maximum serving size. According to Monash, this means these foods are safe to eat in large servings. You can read more about low FODMAP foods without limits here.

This recipe also uses fish sauce. Monash has listed fish sauce as low FODMAP in servings of 1 tbsp (44 g) per sitting. Servings of 1/2 a cup or more are high in both mannitol and GOS. Our recipe uses 1 tbsp of fish sauce for 8 servings. This works out to 5.5 g per serving which is well within Monash’s suggested range.

Last but not least, lime juice. According to the Monash app, lime juice is low FODMAP in servings of 1 cup (250 g) per serving. Servings of 1.5 cups (300 g) or more are high in the FODMAP fructan. Our recipe uses 2 tbsp of lime juice total. This works out to 7.81 g per serving, which is well within the recommended range.

Show Your Work (FODMAP Math)

This recipe has a ton of ingredients! Worried they’ll stack up on you? Take a deep breath, friend! While low FODMAP ingredients can add up, they only cause problems if they’re from the same FODMAP group. This is a phenomenon called FODMAP stacking (you can read more about it here).

For the record, here are the FODMAPs found in each serving of this low FODMAP Thai noodle soup:

Fructose = 0.4
Lactose = 0
Fructans = 0.1
GOS = 0.2
Polyols = 1.5
