Ingredients You’ll Need
You might be surprised how just a handful of simple ingredients can create such an irresistibly moist, cheesy, and flavorful casserole. Each component brings something special—texture, richness, color, or that classic cornbread appeal—but together, they make this dish shine.
- Zucchini (1 cup, grated & squeezed dry): Adds moisture and subtle earthiness while sneaking in nutritious veggies.
- Cornbread mix (1 box, 8.5 oz): The classic base that gives the casserole a delicious, fluffy structure in minutes.
- Sour cream (1/2 cup): Infuses extra creaminess, tenderness, and just a hint of tang.
- Milk (1/3 cup): Helps create the perfect pourable batter and light crumb.
- Eggs (2 large): Binds everything together for a set, sliceable casserole.
- Corn kernels (1 cup): Adds juicy pops of sweetness and classic cornbread flavor; use whatever you have on hand.
- Cheddar cheese (1/2 cup, shredded): Melts throughout for that crave-worthy, gooey bite in every forkful.
- Green onions (1/4 cup, chopped): Adds a mild oniony zing and a pretty pop of color.
- Garlic powder (1/2 teaspoon): Lends savory depth that rounds out the flavors.
- Salt (1/2 teaspoon): Balances and enhances every other flavor.
- Black pepper (1/4 teaspoon): Adds just a hint of warmth and subtle heat.
- Melted butter (1 tablespoon, for greasing): Guarantees nothing sticks and adds a little buttery flavor to the edges.
How to Make Deliciously Easy Zucchini Cornbread Casserole
Step 1: Prep Your Pan and Oven
Get things started by preheating your oven to 375°F (190°C). Grab an 8×8-inch baking dish and brush it generously with melted butter. This step not only prevents any sticking, but also infuses the casserole edges with irresistible, golden buttery flavor.
Step 2: Whisk the Wet Ingredients
In a large mixing bowl, combine the sour cream, milk, and eggs. Give them a good whisk until the mixture is smooth, creamy, and fully blended. These ingredients will make sure your cornbread stays super moist and fluffy instead of dry.
Step 3: Stir in the Cornbread Mix
Add the cornbread mix to your wet ingredients and stir with a spatula or wooden spoon just until everything is combined. No overmixing needed here—a few lumps are just fine for tender results.
Step 4: Fold In the Veggies and Cheese
Now for the fun part: fold in your squeezed-dry zucchini, corn kernels, shredded cheddar, chopped green onions, garlic powder, salt, and black pepper. Mix everything together until all the tasty add-ins are evenly distributed. The batter will look thick and colorful—exactly what you want!
Step 5: Bake to Golden Perfection
Pour the mixture into your prepared dish and use a spatula to smooth the top. Pop it in the oven and bake for 35 to 40 minutes. When the casserole is beautifully golden and a toothpick poked in the center comes out clean, you know it’s ready. Let it cool for 5 to 10 minutes before slicing—this helps it set so every piece comes out picture-perfect.
How to Serve Deliciously Easy Zucchini Cornbread Casserole

Garnishes
Add an extra layer of flavor and a burst of freshness by sprinkling chopped fresh herbs like parsley, cilantro, or chives over the top just before serving. For a little zing, try a dollop of sour cream or a drizzle of hot sauce on individual slices.
Side Dishes
This casserole goes well with just about anything! Pair it with a hearty chili, grilled or roasted meats, or a fresh green salad. It’s also a fantastic partner for summer BBQs and potlucks, holding its own on a buffet table alongside other favorites.
Creative Ways to Present
Try cutting the Deliciously Easy Zucchini Cornbread Casserole into bite-sized squares for a fun party appetizer, or serve alongside a bowl of soup for a comforting lunch. You can even use slices as the base for breakfast with a fried egg on top—the options are endless.
Make Ahead and Storage
Storing Leftovers
Keep any leftover Deliciously Easy Zucchini Cornbread Casserole tightly covered in the refrigerator. It stays moist and delicious for up to 3 days—just slice off what you need and warm it up when hunger strikes.
Freezing
This casserole is surprisingly freezer-friendly! Once cooled, wrap individual slices in plastic wrap and store in a freezer-safe container. They’ll keep well for up to 2 months, making future mealtime a breeze.
Reheating
To reheat, simply pop a slice or two in the microwave until hot, or warm larger portions in a 325°F oven until heated through. This keeps the casserole’s moist texture and ensures the cheesy bits get perfectly melty again.
FAQs
Can I make Deliciously Easy Zucchini Cornbread Casserole gluten-free?

Can I add protein to this casserole?
