Water with a pinch of salt and nutritional yeast (Best Option)
1 cup water + 1/8 tsp salt + 1 tsp nutritional yeast per 1 cup vegetable brothThis substitute works because nutritional yeast provides a mild savory, umami flavor similar to vegetable broth, enhancing the crepe batter without adding fat or color. The pinch of salt balances the flavor to mimic broth seasoning.
For best results, dissolve the salt and nutritional yeast fully in water before mixing into the batter to ensure even flavor distribution. Avoid adding too much nutritional yeast to prevent a cheesy or bitter taste.
Compared to vegetable broth, this substitute maintains the delicate flavor and moisture balance in crepes, resulting in a similarly tender and flavorful final product without introducing unwanted complexity.
