How to Make Zucchini Cornbread Casserole Recipe
Step 1: Prepare Your Oven and Baking Dish
Start by preheating your oven to 375°F (190°C). While it’s warming up, grease a 9×13-inch baking dish to prevent sticking and ensure those beautifully baked edges.
Step 2: Prep the Zucchini
Grate the zucchini and place it in a colander. Sprinkle the grated zucchini with salt and allow it to rest for 10 minutes so the salt can draw out excess moisture. This step is crucial—squeezing out the liquid afterward keeps your casserole from getting soggy and concentrates the flavors.
Step 3: Mix Dry Ingredients
In a large bowl, whisk together the yellow cornmeal, all-purpose flour, baking powder, baking soda, and black pepper. These dry ingredients form the sturdy yet tender base of your casserole.
Step 4: Combine Wet Ingredients
In a separate bowl, beat the buttermilk, eggs, and melted butter until they’re fully blended. This mixture adds moisture, richness, and the perfect touch of tanginess.
Step 5: Bring It All Together
Create a well in the center of your dry ingredients and pour in the buttermilk mixture. Stir gently just until everything is combined—you want to avoid overmixing to keep the texture light and tender.
Step 6: Fold in the Good Stuff
Now for the best part! Fold in the well-drained zucchini, shredded cheddar cheese, chopped green onions, and corn kernels until they’re evenly distributed throughout the batter. This mixture promises every bite is packed with flavor and texture.
Step 7: Bake to Perfection
Pour the batter into your prepared baking dish and smooth the top with a spatula. Slide it into your preheated oven and bake for 35 to 40 minutes until the casserole is beautifully golden brown, and a toothpick inserted into the center comes out clean.
Step 8: Cool and Enjoy
Let the casserole rest for a few minutes after baking. Cooling slightly makes it easier to cut and allows the flavors to settle, ensuring that each slice is a perfect balance of creamy, cheesy, and fresh.
