Begin by preheating your oven to 350°F (175°C). Prepare a standard loaf pan by greasing it lightly or lining it with parchment paper for easy removal later.
In a medium mixing bowl, sift together the flour, baking powder, baking soda, and salt. Set this bowl aside.
In a separate large mixing bowl, combine the Greek yogurt and granulated sugar. Blend until smooth and creamy.
Incorporate the eggs into the yogurt mixture, then add the lemon zest, lemon juice, vanilla extract, and melted butter. Whisk until well-combined and smooth.
Gradually introduce the dry flour mixture to the wet ingredients. Stir gently just until combined—do not overmix.
Carefully fold in the blueberries using a spatula, taking care not to break them.
Pour the completed batter into the prepared loaf pan and smooth the top.
Bake in your preheated oven for 55-65 minutes, until a toothpick inserted into the center comes out clean.
Once baked, remove the loaf from the oven and let it cool in the pan for about 10 minutes. Then transfer it to a wire rack to cool completely.
Notes
For an attractive serving, slice the loaf and arrange the pieces on a beautiful platter. Garnish with additional fresh blueberries and a light sprinkle of lemon zest.
