Canola Oil (Best Option)
1:1 (1 cup canola oil per 1 cup vegetable oil)Canola oil is a neutral-flavored oil with a fatty acid profile similar to vegetable oil, primarily composed of unsaturated fats. This ensures it provides the necessary moisture and fat content to keep zucchini bread tender and moist.
When substituting, use the exact same amount as vegetable oil. Ensure the oil is fresh to avoid off-flavors, and mix thoroughly to incorporate evenly.
The final zucchini bread will have the same moist crumb and subtle flavor, making canola oil an excellent 1:1 substitute with no noticeable difference.
