⭐ Vegetable Oil (Best Dairy-Free Option)
1 tablespoon per 1 tablespoon of butterVegetable oil is a pure fat that replaces the fat content of butter, which is essential for tenderizing the dough and maintaining moisture. In bagels, fat helps to soften the crust slightly and improve chewiness by lubricating gluten strands.
When substituting, use the exact amount to avoid excess oiliness, which can weigh down the dough. Mix thoroughly to ensure even fat distribution. Because vegetable oil is liquid at room temperature, the dough may be slightly less firm during shaping.
The final bagel will have a slightly softer crust compared to butter but will retain the characteristic chew and moisture, making it a reliable substitute.
