โญ Vegetable Oil (Canola or Sunflower) (Best Vegan Option)
3/4 tablespoon oil per 1 tablespoon butterVegetable oils like canola or sunflower are pure fats without water or milk solids, which means they lack the components that contribute to the Maillard reaction and flavor development in French toast. However, their neutral taste and high smoke points make them a practical substitute.
Use slightly less oil than butter to avoid greasiness and cook at moderate heat to prevent burning. Because there is no water content, the crust may brown less evenly.
The final French toast will be less rich and slightly less crispy, with a more neutral flavor profile.
