Ingredients

  • 1 cup cornmeal
  • 1 cup all-purpose flour
  • 1 tablespoon baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon salt
  • 2 large eggs
  • 1 cup buttermilk (or milk with 1 tbsp lemon juice)
  • ½ cup vegetable oil or melted butter
  • 2 tablespoons sugar (optional)
  • 1 ½ cups zucchini, diced or shredded (squeeze lightly to remove excess water)
  • 1 cup shredded cheddar cheese (or mozzarella for a milder flavor)
  • ½ cup chopped scallions or onions

Instructions

  1. Preheat & prepare dish
    Heat the oven to 350°F (175°C). Lightly grease a 9×9 baking dish or similar size.
  2. Mix dry ingredients
    In a large bowl, combine cornmeal, flour, baking powder, baking soda, and salt.
  3. Combine wet ingredients
    In another bowl, whisk eggs, buttermilk, oil, and sugar until smooth.
  4. Bring it together
    Pour the wet ingredients into the dry, stirring gently until just combined.
  5. Add vegetables & cheese
    Fold in zucchini, cheese, and scallions until evenly distributed.
  6. Bake
    Transfer batter to the prepared dish. Bake for 35–40 minutes, or until the top is golden and a toothpick inserted in the center comes out clean.
  7. Cool & serve
    Allow to cool slightly before slicing into squares. Serve warm as a side dish or a light main.
