⭐ Canola Oil (Best Vegan Option)
1:1 (1 tablespoon olive oil = 1 tablespoon canola oil)Canola oil is a neutral-flavored oil with a fatty acid profile similar to olive oil, making it an excellent substitute in quiche where the fat's role is to provide moisture and richness without overpowering other flavors. The liquid state at room temperature helps maintain the smooth custard texture.
When substituting, ensure the oil is fresh to avoid any off-flavors. Because canola oil has a higher smoke point, it can also be used safely if the recipe involves any light sautéing before mixing.
The final quiche will have a slightly less fruity flavor but will retain the creamy mouthfeel and tender crumb typical of olive oil-based recipes.
