Will arrowroot powder work as a cornstarch substitute in yeasted dough?
Yes, at 1:1. Very similar behaviour. Better for acid-based and frozen sauces. Bake-test before scaling up.
Best Cornstarch Substitutes for Yeasted Breads
Prioritize substitutions that protect gluten development and fermentation performance. Bread dough is less forgiving than quick bakes. Structure and fermentation can collapse with poor substitutions.
Can I make bread without cornstarch?
Yes. Start with Arrowroot Powder at 1:1, then adjust liquid or bake time in small steps after a test batch.

Rice Flour
goodUse 2 tbsp rice flour per 1 tbsp cornstarch
A reliable gluten-free thickener for gravies and stews and a crisp coating for frying. Finishes opaque rather than glossy.
Tapioca Starch
goodUse 2 tbsp tapioca per 1 tbsp cornstarch
Creates chewier, more elastic texture. Good for pie fillings.
All-Purpose Flour
goodUse 2 tbsp flour per 1 tbsp cornstarch
Half the thickening power. Creates opaque, less glossy results.
Potato Starch
good1:1
Thickens at a lower temperature and gives a clear, glossy finish. Add near the end of cooking — prolonged boiling thins it out.
Xanthan Gum
moderate¼ tsp per 1 tbsp cornstarch, whisked in gradually
Thickens without heat and holds up to acid and freezing. Very easy to overdo — too much turns sauces slimy.
