Preheat the oven to 350 degrees Fahrenheit.
In a large bowl, combine the 3 1/4 cup flour, 2 cups granulated sugar, 2 tsp baking soda, 1 tsp salt, 1 tsp cinnamon, and 1 tsp nutmeg.
In a separate bowl, combine 4 eggs, 3 cups zucchini, 1 cup vegetable oil, and 1 tsp lemon juice.
Use an electric hand mixer to combine the wet ingredients into the dry until well combined.
Use a wooden spoon to add in the (optional) nuts if desired.
Grease 2 (9”x5”x2”) glass loaf pans. Divide the batter evenly between the two loaf pans.
Bake in the preheated oven for 55 minutes or until a toothpick comes out clean.
Cool on a cooling rack until room temperature, then turn the zucchini bread out of the pan. Serve and enjoy!
