Preheat your oven to 350°F (175°C). Prepare a 9x5-inch loaf pan by greasing it lightly with cooking spray or butter, or line it with parchment paper for easy removal.
In a large mixing bowl, combine the plain Greek yogurt and granulated sugar, whisking vigorously until the mixture is smooth and creamy.
Incorporate the eggs one at a time, ensuring each egg is fully blended into the mixture before adding the next.
Pour in the vegetable oil, vanilla extract, lemon zest, and freshly squeezed lemon juice. Whisk everything together until well combined and smooth.
In a separate bowl, sift together the all-purpose flour, baking powder, baking soda, and salt.
Gradually fold the dry mixture into the wet ingredients, stirring gently until no streaks of flour remain.
Carefully pour the batter into the prepared loaf pan, using a spatula to smooth the top for an even bake.
Bake in the preheated oven for 50-60 minutes, or until a toothpick inserted into the center comes out clean with just a few crumbs.
Once baked, let the loaf cool in the pan for approximately 10 minutes. Then, carefully transfer it to a wire rack to cool completely.
Notes
For an elegant presentation, dust with powdered sugar and garnish with lemon slices or mint.
