Allergen Breakdown

Dairy-Free

Likely OK

Khao soi uses coconut milk, not dairy.

Gluten-Free

Likely contains restriction

Both the soup noodles and the crispy topping noodles are wheat-based egg noodles.

Peanut-Free

Likely OK

Peanuts are not traditionally added to khao soi.

Tree Nut-Free

Check with staff

Coconut is FDA-classified as a tree nut. If coconut allergy is a concern, this dish is unsafe.

Shellfish-Free

Likely contains restriction

The red curry paste contains shrimp paste (kapi) as a traditional ingredient.

Egg-Free

Likely contains restriction

Both the soup and crispy topping noodles are egg noodles. Egg is a structural ingredient.

Fish-Free

Likely contains restriction

Fish sauce is the primary seasoning in khao soi.

Soy-Free

Check with staff

Some versions add soy sauce to the broth. Verify with the restaurant.

Sesame-Free

Likely OK

Sesame is not a traditional ingredient in khao soi.

Vegetarian

Likely contains restriction

Contains meat, shrimp paste in the curry base, and fish sauce.

Key risk: Khao soi is unique among Thai dishes in using egg noodles rather than rice noodles. The noodles contain both wheat (gluten) and egg. The crispy noodle topping is fried versions of the same noodles, doubling the exposure. The curry paste also contains shrimp paste, adding shellfish to an already allergen-dense dish.
