Preheat the oven to 350°F.
Whisk together the flour, sugar, garlic powder, onion powder, parsley, baking powder, salt, and baking soda in a large bowl.
Stir 2 1/4 cups of the shredded cheddar cheese into the dry mixture.
In another bowl, beat together the melted butter, milk, sour cream, and eggs until well combined.
Pour the wet ingredients into the dry ingredients and fold together with a spatula just until combined.
Grease a 9x5-inch loaf pan with nonstick spray or butter.
Transfer the batter into the prepared loaf pan and smooth the top. Sprinkle the remaining 1 cup of cheddar cheese over the top.
Cover the pan loosely with foil and bake in the preheated oven for 25 minutes. Remove the foil and bake for an additional 25-30 minutes, or until a toothpick inserted into the center comes out clean.
Allow the bread to cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.
