Preheat oven to 350°F. Lower the oven rack to the lower third position, this will help from the top of the bread from browning too much.
Grease a 9×5-inch loaf pan with butter and set aside.
In a large bowl, whisk the flour, baking soda, cinnamon, nutmeg, ginger, and salt together until combined.
In a medium bowl, whisk the eggs, granulated sugar, and brown sugar together until combined. Whisk in the pumpkin, and oil.
Pour these wet ingredients into the dry ingredients and whisk together.
Pour the batter into the prepared loaf pan and bake for 45-50 minutes. If the bread looks like it is browning too much, loosely cover the top of the bread with parchment paper.
The bread is done when a toothpick inserted in the center comes out clean. Let the bread cool before removing it from the loaf pan and slicing.
