Step 1: Preheat the Oven - Begin by preheating your oven to 350°F (175°C). This ensures that your bread will bake evenly and rise beautifully.
Step 2: Prepare the Zucchini - Grate the zucchini using a box grater or food processor. Make sure to drain it well to avoid excess moisture in the bread.
Step 3: Mix Dry Ingredients - In a large mixing bowl, whisk together the all-purpose flour, salt, baking soda, baking powder, ground cinnamon, and nutmeg (if using). Set aside.
Step 4: Combine Wet Ingredients - In another bowl, beat the eggs until they are frothy. Add the vegetable oil, white sugar, brown sugar, and vanilla extract. Mix until combined.
Step 5: Combine Wet and Dry Mixtures - Slowly add the wet ingredients to the dry ingredients, stirring gently until just combined. Be careful not to overmix; it’s okay if there are a few lumps.
Step 6: Fold in Zucchini and Walnuts - Gently fold in the grated zucchini and walnuts using a spatula. This is where the magic happens—your batter will come together beautifully!
Step 7: Pour into Loaf Pan - Pour the batter into a greased loaf pan. Use the spatula to smooth the top, ensuring it bakes evenly.
Step 8: Bake - Place the loaf pan in the preheated oven and bake for about 60 minutes, or until a toothpick inserted in the center comes out clean.
Step 9: Cool - Once baked, remove the bread from the oven and let it cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.
