1. Adjust oven rack to middle position and heat oven to 325°F. Grease 8 1/2 x 4 1/2-inch loaf pan.

2. Place zucchini in center of dish towel. Gather ends together and twist tightly to drain as much liquid as possible, discarding liquid (you should have 1/2 to 2/3 cup liquid). Whisk brown sugar, oil, eggs, vanilla, and orange zest together in medium bowl. Fold in zucchini.

3. Whisk all-purpose flour, whole-wheat flour, salt, baking powder, baking soda, nutmeg, and cardamom together in large bowl. Fold in zucchini mixture until just incorporated. Fold in pistachios. Pour batter into prepared pan and sprinkle with granulated sugar.

4. Bake until top bounces back when gently pressed and toothpick inserted in center comes out with few moist crumbs attached, 65 to 75 minutes. Let bread cool in pan on wire rack for 30 minutes. Remove bread from pan and cool completely on wire rack. Serve.
