Making Zucchini Cornbread Casserole is simple, and it comes together in just a few easy steps. Follow this guide for a perfect dish every time.

Step 1: Prepare the Ingredients

• Preheat your oven to 375°F (190°C). Grease a 9×9-inch baking dish with butter or nonstick spray.
• Grate 2 cups of zucchini and place it in a clean kitchen towel or cheesecloth. Squeeze out as much excess moisture as possible. This step is crucial to prevent a soggy casserole.

  • 1 tsp baking powder
  • ½ tsp salt

Step 5: Assemble & Bake
