Ingredients You’ll Need
This recipe keeps things simple yet striking, using familiar ingredients that each play an essential role in crafting the perfect texture, flavor, and color of the casserole you will love.

- 1 cup milk: Keeps the batter smooth and tender.
- ¼ cup melted butter: Infuses buttery richness that makes the cornbread moist and flavorful.
- ½ cup sour cream (optional): Adds creamy tanginess and extra moisture for a tender crumb.
- ½ teaspoon onion powder: Gives a subtle savory depth without overwhelming the other flavors.

How to Make Zucchini Cornbread Casserole Recipe
Step 1: Prepare the Zucchini
Start by grating your zucchini and then take the extra step to squeeze out the moisture using a kitchen towel or paper towels. This is crucial because zucchini holds a lot of water, and removing excess moisture keeps the casserole from becoming soggy.
Step 2: Prep the Oven and Baking Dish
Preheat your oven to 350°F (175°C). Meanwhile, grease a 9×9-inch baking dish well with butter or cooking spray so your casserole won’t stick and can come out in perfect slices.
Step 3: Mix the Dry Ingredients
In a large mixing bowl, combine the cornmeal, all-purpose flour, baking powder, salt, and sugar. Make sure you stir everything together thoroughly so the rising agent and seasonings are distributed evenly throughout the batter.
Step 4: Combine the Wet Ingredients
In a separate bowl, whisk together the eggs, milk, and melted butter. If you’re including sour cream for creaminess, add it here too. Fold in the drained zucchini carefully to get everything incorporated without losing the shredded texture.
Step 5: Bring It All Together
Pour the wet mixture into the bowl with your dry ingredients. Stir gently but fully until everything blends into a smooth batter. This is also the perfect time to stir in your onion powder, garlic powder, and shredded cheddar cheese if you want an extra punch of flavor and gooeyness inside.
Step 6: Bake the Casserole
Transfer the batter into your greased baking dish and spread it out evenly. Sprinkle the breadcrumbs and Parmesan cheese on top to create a crunchy, golden topping. Bake for 35 to 40 minutes until the surface is a beautiful golden brown and a toothpick inserted in the center comes out clean.
Step 7: Cool Slightly and Serve
Once baked, let the casserole sit for a few minutes to firm up so it slices easily. A sprinkle of fresh parsley on top adds a lovely pop of color and freshness before serving.

Garnishes
A simple garnish can elevate your dish from comforting to delightful. Fresh chopped parsley or chives bring a bright contrast, while a little grated sharp cheddar on top can add an irresistible melty crown for cheese lovers.
Side Dishes
This casserole pairs beautifully with grilled or roasted meats, like chicken or pork, and fresh green salads. It’s also a wonderful partner to hearty soups, turning an ordinary meal into a comforting feast.
Creative Ways to Present
For a fun twist, try turning the casserole into individual portions by baking it in muffin tins. This makes it perfect for parties or lunchboxes. You can also layer it with a savory tomato sauce and shredded cheese for a lasagna-inspired casserole that will wow your guests.
Make Ahead and Storage
Storing Leftovers
Wrap the cooled leftover casserole tightly with plastic wrap or foil and place it in the refrigerator. It will stay fresh for up to 3 days, making it easy to enjoy without wasting any.
Freezing
You can freeze the casserole either before or after baking. Cover it well with foil and place it in an airtight container or freezer bag. It will keep well for up to 2 months. When ready, thaw in the refrigerator overnight before reheating.
Reheating
Reheat your zucchini cornbread casserole gently in the oven at 325°F (160°C) for about 15-20 minutes until warmed through. This method preserves the crunchy topping better than microwaving, which can make it soggy.
FAQs
Can I use yellow squash instead of zucchini?
Absolutely! Yellow squash has a similar texture and taste, so it can be used in place of zucchini without altering the flavor much at all.
Is sour cream necessary in this recipe?
Not at all. Sour cream is optional and adds extra creaminess and moisture, but you can easily omit it or substitute with yogurt for a lighter version.
Can I make this casserole gluten-free?
Yes! Substitute the all-purpose flour with a gluten-free flour blend, and use gluten-free breadcrumbs for the topping to make this dish gluten-free while maintaining great texture.
How do I know when the casserole is done baking?
Look for a golden-brown top and a toothpick inserted in the center coming out clean. The casserole should feel set and not jiggly before pulling it out of the oven.
Can I add extra vegetables or cheese?
You can! Add finely chopped bell peppers, corn kernels, or even cooked bacon for extra flavor and texture. Just be mindful not to add too much liquid to keep the right consistency.
