Ingredients

  • 3/4 cup chopped onion
  • 3 cups flour
  • 1/4 cup sugar
  • 1/2 cup Parmesan cheese
  • 2 tablespoons Parmesan cheese (for topping)
  • 5 teaspoons baking powder
  • 1/2 teaspoon baking soda
  • 1 1/2 teaspoons salt
  • 1/3 cup melted butter
  • 1 cup buttermilk
  • 2 eggs

Instructions

  1. Combine the first seven ingredients, saving 2 tablespoons of Parmesan cheese for topping.
  2. Mix together melted butter, buttermilk, eggs, and grated zucchini.
  3. Carefully stir the wet mixture into the flour mixture until just combined.
  4. Spoon the batter into a greased 9-inch round baking pan.
  5. Sprinkle with the remaining 2 tablespoons of Parmesan cheese on top.
  6. Bake at 350°F for 45 to 50 minutes or until a toothpick inserted into the center comes out clean.
  7. Cool for 10 minutes before removing from the pan.

Tips & Substitutions

For added flavor, consider incorporating fresh herbs like thyme or basil into the batter. If you don't have buttermilk on hand, you can substitute it with regular milk mixed with a tablespoon of vinegar or lemon juice. This bread can also be made with whole wheat flour for a healthier option. Make sure not to overmix the batter to keep the bread light and fluffy.

Serving Suggestions

This savory bread pairs beautifully with a fresh salad, such as Tim'S 5 Minute Salad, or can be served alongside soups and stews. Consider cutting it into thick slices and toasting them for a delightful crunch. A spread of herb-infused butter or cream cheese can elevate the flavors, making it a versatile addition to any meal.
