Heat the oven to 375°F. Prepare a 9-by-5-inch loaf pan.
Shred enough zucchini to measure 2 1/2 cups. Do not squeeze it dry.
2½ C Shredded Zucchini
In a large bowl, mix 2 1/2 cups shredded zucchini, 1 cup unsweetened applesauce, 1 cup granulated sugar, 1 cup brown sugar, 3/4 cup oil, and 2 teaspoons vanilla extract.
1 C Unsweetened Applesauce, 1 C Sugar, 1 C Brown Sugar, ¾ C Olive oil, 2 tsp Vanilla Extract
In a second bowl, whisk 3 cups all-purpose flour, 1 teaspoon salt, 1 teaspoon baking soda, and 2 teaspoons cinnamon.
3 C All-Purpose Flour, 1 tsp Salt, 1 tsp Baking Soda, 2 tsp Cinnamon
Add the dry mixture to the wet mixture and stir just until no dry flour remains.
Let the batter rest for 15 minutes.
Transfer the batter to the prepared pan and bake for 70 to 75 minutes.
Begin checking at 60 minutes. The loaf is ready when a toothpick inserted near the center comes out clean.
Let the loaf cool before slicing.
