I’m making chicken noodle soup and want to keep it low carb. I asked Duck Duck ai for a recipe:

Coconut-flour noodles (egg + xanthan + psyllium)

Ingredients (2 servings)

90 g coconut flour
2 eggs
1–2 tsp psyllium husk (start with 1 tsp, add more if dough won’t hold)
1/4 tsp xanthan gum
1/2 tsp salt (optional)
1–2 tbsp warm water (as needed)
1 tsp olive oil (optional, helps pliability)
Make the dough

In a bowl, whisk coconut flour, psyllium, xanthan gum, and salt.
Add eggs (and oil if using). Mix until you get a thick, slightly sticky dough.
Add warm water 1 tsp at a time only if the dough seems too dry to come together. Don’t make it watery.
Rest 5–10 minutes (it thickens as psyllium hydrates).
Shape

If you want “noodles”: use a rolling pin between two sheets of parchment (dust with a tiny bit of coconut flour only if needed), roll thin, then cut into strips.
If it tears easily, roll thinner and let it rest 2–3 more minutes before cutting.
Cook (best method)

Bring a wide pot of salted water to a gentle boil.
Add noodles carefully; stir once at the start.
Simmer gently until set and tender, about 2–4 minutes (do not boil aggressively or they may break).

I’ll let you know if it works out!

No, no it didn’t turn out as per this recipe. Instead…

I halved the keto recipe, added one egg and about 1 cup ap flour. The noodles turned out ok. They are softer than usual, but still good and use less ap flour with more fiber thanks to the coconut flour. So, next time I’ll try:

50g coconut flour
2 eggs (maybe 3)
2 tsp psyllium husk
1/4 tsp xanthan gum
1 tsp salt
1–2 tbsp water (as needed)
100 gm ap flour

I’ll need to test this at some point and report back.
