Method
Prepare and preheat
- Preheat oven to 350°F and line a 9×5-inch loaf pan with parchment, leaving an overhang; lightly grease the exposed sides.
Drain zucchini
- Grate the zucchini on the large holes of a box grater; place in a fine-mesh sieve and let drain 10 minutes, then gently squeeze out excess water until no free liquid remains.
Mix wet ingredients
- In a large bowl whisk together oil, beaten egg, brown sugar, and vanilla until smooth.
Mix dry ingredients
- In a separate bowl whisk the flours, baking soda, baking powder, cinnamon, nutmeg, and salt.
Combine
- Fold the dry ingredients into the wet until just combined, then fold in drained zucchini and optional nuts or chocolate chips; do not overmix.
Bake
- Pour batter into prepared pan, smooth the top, and bake at 350°F for 50–60 minutes, checking at 50 minutes with a toothpick or instant-read thermometer (200–205°F in the center). If the top browns too quickly, tent loosely with foil.
Cool and serve
- Cool the loaf in the pan 10 minutes, then lift out using the parchment overhang and cool completely on a wire rack before slicing.
Notes
Drain the zucchini well—this single step prevents a gummy center. If substituting melted butter for oil, expect a slightly firmer crumb. For muffins, bake at 350°F for 18–22 minutes. Store wrapped at room temperature up to 3 days or freeze slices for up to 3 months.
