Spray a 9x5-inch loaf pan with baking spray. You could also line with parchment paper and spray with baking spray. Preheat the oven to 350 degrees.
Prep a loaf pan with baking spray or line it with parchment paper and spray the paper with baking spray.
Grate the zucchini with a box grater. Gather up the grated zucchini in a cheesecloth (or with your hands)and squeeze it together over a colander.
Mix the egg with the sugar and oil. Stir in the grated zucchini. In a separate bowl, whisk together the flour, sea salt (regular salt is fine too), baking soda, baking powder, spices and poppy seeds.
Add the dry ingredients to the zucchini mixture. Stir until combined.
Transfer batter into the loaf pan. Bake for 55-60 minutes, or until a tester inserted in middle comes out clean. I usually lower my oven temperature to 325F for the last 30 minutes of baking time. Every oven is different. I lower mine as if I leave it at 350F for the entire baking time it will overbake.
Let cool in pan for 10 minutes and then gently remove onto a wire rack to thoroughly cool.
