Low FODMAP Mee Siam Thai Chicken Noodle Soup
Mee Siam is a comforting Thai chicken noodle soup built on aromatic ginger-infused chicken and a savory low FODMAP broth. This version strips out traditional high FODMAP ingredients like garlic and shallots while preserving the dish's essential character: silky egg noodles, tender fish balls, and poached chicken bound by sweet soy and oyster sauce. The magic lives in layers—ginger warmth, umami depth from the broth and condiments, and textural contrast from crispy ground peanuts and delicate egg ribbons. Make this if you're managing IBS or following a low FODMAP diet without sacrificing authentic flavor. Serve it warm in bowls for lunch or light dinner. What sets this version apart is the careful ingredient substitution that honors the original's soul while meeting strict dietary needs, plus the technique of building the chicken topping separately so each component shines.

Assemble bowls by layering noodles, cooked fish balls, chicken topping, and broth. Top with egg ribbons, coriander leaves, and toasted ground peanuts.
Tips
Toast peanuts yourself if possible: dry-roast unsalted peanuts in a pan for 3-5 minutes, then pulse in a food processor. Homemade tastes fresher and you control salt and quality.
Create thin, silky egg ribbons by pouring a small amount of egg mixture into a hot oiled non-stick pan and tilting constantly. Low heat prevents browning and keeps them tender.
Build the ginger paste by crushing fresh ginger with the side of a knife first, then pound finely. This releases oils and deepens flavor better than a microplane alone.
Good to Know
Chicken topping and broth with fish balls keep refrigerated in separate airtight containers for 3 days. Noodles and egg ribbons best assembled fresh. Reheat broth gently; store peanuts dry at room temperature.
Prepare chicken topping and broth up to 2 days ahead. Cook egg noodles fresh and set aside. Toast peanuts and prepare egg ribbons up to 4 hours ahead, then refrigerate. Assemble bowls to order.
Serve in warm bowls with all components layered. Accompany with lime wedges and dried chili flakes on the side for customizing heat and brightness.
Common Mistakes
Cook ginger less than a minute after adding: overcooking turns it bitter and muddy the broth flavor.
Whisk eggs gently, not vigorously: tiny air bubbles prevent thin, silky omelets and create tough edges.
Don't skip cooling omelets before rolling: warm sheets tear when sliced, creating shaggy rather than elegant ribbons.

FAQ
Can I use store-bought rotisserie chicken instead of poaching?
Yes. Shred or slice rotisserie chicken and warm it in the ginger-soy mixture for 1-2 minutes. You'll lose the silky poached texture but gain convenience. Homemade poached stays more tender in broth.
What if I don't have fish balls?
Substitute halved firm tofu, cubed chicken, or omit entirely. Fish balls add umami and texture but aren't essential. The broth and chicken topping carry the dish. Low FODMAP shrimp (if tolerated) works too.
How long can I keep assembled bowls?
Assemble immediately before eating. Noodles absorb broth and become mushy within 10 minutes. Egg ribbons soften and peanuts lose crunch. Store components separately for 3 days, then combine fresh.
