Preheat the Oven: Preheat your oven to 375°F. Prepare two 8x4-inch loaf pans, either grease them lightly and dust with flour, or line with parchment paper. You can also use foil baking pans, sprayed with non-stick spray.

Mix Dry Ingredients: In a medium-sized bowl, combine the flour, baking soda, cinnamon, nutmeg, and salt. Stir well to ensure the spices are evenly distributed.

Combine Wet Ingredients: In a large bowl, mix the granulated sugar and vegetable oil until well combined and smooth. Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.

Combine Wet and Dry Ingredients: Gradually add the dry ingredient mixture to the wet ingredients, stirring until just combined. Be careful not to overmix, as this can make the bread dense.

Add the Zucchini: Gently fold the grated zucchini into the mixture, ensuring it is evenly distributed.

If using nuts or chocolate chips, gently fold them into the batter as well.

Bake the Bread: Divide the batter evenly between the two prepared loaf pans. Bake in the preheated oven for 45-55 minutes, or until a toothpick inserted into the center of the loaves comes out clean.

Cool and Serve: Once done, let the loaves cool in the pans for about 10-15 minutes before transferring them to a wire rack to cool completely. Slice and enjoy!
