Preheat your oven to 350°F (175°C) and grease a 9x5-inch loaf pan or line it with parchment paper.
In a large mixing bowl, combine the grated zucchini, Greek yogurt, granulated sugar, brown sugar, and vegetable oil. Mix well until combined.
Add in the eggs, lemon zest, and lemon juice. Whisk until the mixture is smooth and well blended.
In a separate bowl, whisk together the all-purpose flour, poppy seeds, baking powder, baking soda, and salt.
Gradually add the dry ingredients to the wet mixture, stirring until just combined. Be careful not to over-mix the batter.
Pour the batter into the prepared loaf pan, smoothing the top with a spatula.
Bake in the preheated oven for 50-60 minutes, or until a toothpick inserted into the center comes out clean.
Once done, allow the bread to cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely.
Notes
Slice the zucchini bread and dust lightly with powdered sugar, or serve with a dollop of whipped cream on top. Garnish with lemon slices or fresh mint for an added burst of color!
