⭐ Canola Oil (Best Nut-Free Option)
1:1 (1 cup canola oil per 1 cup olive oil)Canola oil is a neutral-flavored vegetable oil with a fatty acid profile similar to olive oil, making it an excellent substitute in baked goods like banana bread. Its liquid state at room temperature ensures the batter remains easy to mix and produces a tender crumb.
When substituting, measure canola oil in equal amounts to olive oil. Avoid overheating the batter to prevent any off-flavors. Because it lacks the fruity notes of olive oil, the banana flavor will be more pronounced.
The final banana bread will have a moist texture and subtle flavor, very close to the original recipe using olive oil, making it the best practical alternative.
