Shred zucchini and salt it generously, then squeeze out excess moisture in a kitchen towel before adding to batter to prevent a soggy loaf and ensure proper texture.

Select bananas with plenty of brown spots for maximum sweetness and moisture content, which reduces the need for added sugar and enhances flavor complexity.

Lightly toast walnuts in a dry skillet for 3-4 minutes before chopping and adding to batter to intensify their nutty flavor and add depth to the bread.

Fold ingredients together gently until just combined—overmixing develops gluten and creates a dense, tough crumb instead of the desired moist, tender texture.

Place your loaf pan in a larger pan filled with hot water during baking to create gentle, even heat and prevent dry edges while keeping the interior supremely moist.
