- 2 large zucchini, grated: Adds fresh moisture and subtle sweetness, plus a lovely tender bite.
- 1 teaspoon salt: Helps draw out zucchini’s moisture and enhances overall flavor.
- 1 cup yellow cornmeal: The star ingredient for that classic cornbread grainy texture and golden color.
- 1 cup all-purpose flour: Balances the cornmeal to keep the casserole tender yet firm.
- 1 tablespoon baking powder: Leavens the batter, making it light and fluffy.
- 1 teaspoon baking soda: Works with the buttermilk to ensure a perfect rise.
- 1/2 teaspoon black pepper: Adds a subtle spicy note, balancing sweetness.
- 3/4 cup buttermilk: Brings tang and moisture to keep every bite soft.
- 2 large eggs: Acts as a binder and adds richness to the casserole.
- 1/4 cup unsalted butter, melted: Deepens flavor and creates a moist crumb.
- 1 cup shredded cheddar cheese: Adds sharpness and gooey texture that melts beautifully throughout.
- 1/4 cup chopped green onions: Gives a fresh, mild onion flavor for extra zing.
- 1/2 cup corn kernels (fresh, frozen, or canned): Punctuates each bite with bursts of sweetness and crispness.
How to Make Zucchini Cornbread Casserole Recipe
Step 1: Prep Your Oven and Dish
Start by preheating your oven to 375°F (190°C). Then generously grease a 9×13-inch baking dish to ensure your casserole bakes evenly without sticking, setting the stage for a smooth release after baking.
Step 2: Prepare the Zucchini
Grate your zucchini and place it in a colander, sprinkling it evenly with salt. Let it sit for about 10 minutes. This step is essential because the salt draws out excess moisture, preventing the casserole from becoming soggy. After sitting, squeeze out as much liquid as you can—it makes a big difference in the texture!
Step 3: Mix Your Dry Ingredients
In a large bowl, combine the cornmeal, all-purpose flour, baking powder, baking soda, and black pepper. Whisking these together ensures even distribution of rising agents and seasoning so that every bite is perfectly textured.
Step 4: Combine the Wet Ingredients
In a separate bowl, whisk together the buttermilk, eggs, and melted butter. This mixture will provide a tender crumb and rich flavor that blends harmoniously with the dry ingredients.
Step 5: Mix Wet and Dry Ingredients
Create a well in the dry ingredients and pour in your wet mixture. Stir gently just until combined—you don’t want to overmix or your casserole could turn dense instead of fluffy.
Step 6: Fold in Veggies and Cheese
Now the best part: fold in your prepared zucchini, shredded cheddar, chopped green onions, and corn kernels. This step ensures even distribution of all those wonderful textures and flavors.
Step 7: Transfer and Smooth
Pour your batter into the greased baking dish and use a spatula to smooth the top evenly. This helps the casserole bake uniformly and looks inviting once golden brown.
Step 8: Bake to Perfection
Pop the dish into your preheated oven and bake for 35 to 40 minutes. You’ll know it’s done when the top turns a beautiful golden-brown and a toothpick inserted in the center comes out clean.
Step 9: Cool Before Serving
Allow the casserole to rest for a few minutes before slicing. This helps it set up, making it easier to serve and enjoy.

FAQs
Can I use yellow squash instead of zucchini?
Absolutely! Yellow squash works beautifully in this casserole and offers a similar texture and moisture content, keeping the same delightful flavor.
Do I have to squeeze the zucchini?
Yes, squeezing out the liquid is very important to prevent the casserole from becoming watery and to ensure a firm, sliceable texture.
Can I make this recipe vegan?
To make it vegan, substitute the eggs with flax eggs, use a plant-based milk like almond or soy in place of buttermilk (with a touch of vinegar), and swap butter for a vegan alternative. Use dairy-free cheese or omit it for a different but still tasty version.
Will the casserole be spicy?
This recipe is mildly seasoned with black pepper only, so it’s more savory than spicy, making it suitable for all tastes including kids.
Can I add other veggies to the casserole?
Definitely! Diced bell peppers, shredded carrots, or chopped spinach can all add extra flavor and nutrition without overpowering the original recipe’s charm.
