Method
Prep and mix the batter
- Preheat the oven to 350°F and grease a 9x5 loaf pan so the loaf releases cleanly after baking.
- Whisk all-purpose flour, baking soda, baking powder, and salt together to evenly distribute the leaveners.
- Beat granulated sugar, eggs, vegetable oil, fresh orange juice, orange zest, sour cream, and vanilla extract until smooth and fully combined, with no streaks visible.
- Stir in the grated squeezed zucchini so it disperses throughout the batter.
- Fold the dry ingredients into the wet ingredients just until combined, then stop mixing as soon as you don’t see dry flour.
Bake and glaze
- Pour the batter into the prepared loaf pan, then bake for 50–58 minutes at 350°F until the top is golden and a toothpick comes out clean.
- Cool the loaf for 15 minutes before glazing so the icing sets properly without running off.
- Whisk powdered sugar, fresh orange juice, and orange zest until smooth, then drizzle generously over the warm loaf for a glossy orange finish.
Notes
For the best crumb, squeeze grated zucchini very dry so the loaf bakes with a tender, non-gummy center. Store airtight at room temperature for up to 2 days or refrigerate up to 5 days; freeze slices for up to 2 months (glaze after thawing for a cleaner set). For a dairy-light swap, use plain Greek yogurt instead of sour cream for similar tang and moisture.
