Preheat your oven to 350°F (175°C) and grease a 9x5 inch loaf pan.
In a large bowl, whisk together the oil, sugar, eggs, and vanilla extract.
Add the grated zucchini to the mixture and stir until combined.
In another bowl, mix the flour, baking soda, baking powder, salt, cinnamon, and nutmeg.
Gradually incorporate the dry ingredients into the wet mixture, stirring gently.
If desired, fold in nuts or chocolate chips.
Pour the batter into the prepared loaf pan.
Bake for 50-60 minutes, or until a toothpick comes out clean.
Let the bread cool in the pan for 10 minutes before transferring to a wire rack.
Slice and enjoy your delicious zucchini bread!
