Grate zucchini finely for better texture. Don’t overmix to keep the bread tender. Adjust moisture by adding ¼ cup water if zucchini is dry. Use room temperature eggs for smoother batter. Test doneness with a toothpick. Cool completely before slicing. Variations include adding chocolate chips, using gluten-free flour, adding spices like ginger or cardamom, nut-free options, citrus zest, or swapping oils.
