Method
Prepare the pan and zucchini
- Preheat the oven to 350°F and grease a 9x5-inch loaf pan or line it with parchment; grate zucchini on the large side of a box grater and lightly press in a towel to remove surface water until just damp.
Mix dry ingredients
- In a medium bowl whisk together the flour, baking soda, baking powder, salt, cinnamon, and nutmeg.
Mix wet ingredients
- In a large bowl whisk the oil, melted butter, brown sugar, granulated sugar, eggs, and vanilla until smooth.
Combine and rest
- Fold the dry ingredients into the wet until almost combined, then gently fold in the grated zucchini and optional mix-ins; let the batter rest 8–12 minutes to hydrate the flour, then give it a final light stir and pour into the prepared pan.
Bake
- Bake at 350°F for 50–60 minutes until the top is golden and a toothpick inserted in the center comes out with a few moist crumbs; tent with foil if the top browns too quickly.
Cool and slice
- Cool the loaf in the pan for 10 minutes, run a knife around the edges, transfer to a rack, and cool completely before slicing to avoid a gummy center.
Notes
Measure grated zucchini packed and lightly pressed; do not squeeze completely dry. Let the batter rest 8–12 minutes before baking to hydrate the flour. Store wrapped at room temperature for up to 3 days or freeze wrapped for up to 3 months.
