01 - Preheat the oven to 350°F. Grease and line a 9x5-inch loaf pan with parchment paper.
02 - Whisk together the flour, baking powder, baking soda, and salt in a medium bowl; set aside.
03 - In a large bowl, whisk the sugar and eggs until light and creamy. Add the vegetable oil, Greek yogurt, vanilla extract, and lemon zest, then mix until smooth.
04 - Gently fold the dry ingredients into the wet mixture until just combined without overmixing.
05 - Toss blueberries with 1 tablespoon of flour to prevent sinking, then fold them carefully into the batter.
06 - Pour the batter into the prepared loaf pan and sprinkle with turbinado sugar if desired.
07 - Bake for 50 to 60 minutes, or until a toothpick inserted in the center comes out clean.
08 - Allow the loaf to cool in the pan for 10 minutes before transferring to a wire rack to cool completely prior to slicing.
