Gathering Your Ingredients for the Perfect Bake

One of the beauties of this Cheesy Zucchini & Corn Bake is that it relies on simple, fresh ingredients that you likely already have or can easily find. The magic happens when these humble components come together, creating a dish that feels both wholesome and indulgent.

Here’s what you’ll need, with a few notes on why each ingredient plays its part:

Save For Later!

Zucchini: We use 2 medium zucchini. Whether you slice or chop them is up to your personal preference – slices offer a nice visual, while chopped pieces integrate a bit more seamlessly into the mix. The key here isn’t just adding the zucchini, but how we prepare it to avoid that dreaded wateriness.
Salt: You’ll need 1 teaspoon, divided. Salt isn’t just for seasoning; a portion of it is essential for our moisture-removing trick with the zucchini! The rest seasons the creamy base.
Corn Kernels: 1 cup of corn adds pops of sweetness and texture. Fresh corn cut straight off the cob is fantastic when in season, but frozen or well-drained canned corn works just as well. Just make sure it’s drained thoroughly if using canned. For another great way to use corn, check out our Black Bean and Corn Fiesta Salad!
Shredded Cheese Blend: 2 cups of shredded cheese make this bake truly cheesy! A blend of cheddar and mozzarella is recommended because cheddar offers sharpness and flavor, while mozzarella provides that lovely stretch and creamy melt. Pre-shredded cheese is convenient, but shredding your own often results in a smoother melt.
Large Eggs: Two large eggs act as a binder, helping the bake to set and hold its shape as it cooks. They are crucial for creating that satisfying, sliceable texture.
Heavy Cream or Milk: 1/2 cup of either creates the creamy base for the casserole. Heavy cream will yield a richer, more decadent result, while milk (whole or 2%) makes it slightly lighter. Choose what you prefer or have on hand!
Plain Breadcrumbs or Crushed Crackers: 1/2 cup of these humble heroes adds structure and, importantly, helps to absorb any residual moisture that the zucchini might release during baking. Plain breadcrumbs are standard, but crushed Ritz crackers or even saltines can add a fun, buttery flavor twist.
Chopped Fresh Parsley: You’ll need 2 tablespoons for mixing in, plus a little extra for garnish. Fresh parsley adds a burst of vibrant color and a fresh, slightly peppery flavor that brightens the entire dish. Don’t skip the fresh herbs!
Black Pepper: 1/4 teaspoon of black pepper adds a touch of warmth and gentle spice to balance the richness.
Garlic Powder (Optional): Just 1/4 teaspoon, but it adds a wonderful depth of savory flavor. If you’re a garlic lover, this is a must!

Crafting Your Cheesy Zucchini & Corn Bake: Step-by-Step

Ready to make this creamy, cheesy goodness? Follow these steps closely, paying special attention to the very first one – it’s our secret weapon against sogginess!

Prepare the Zucchini for Success: This is the make-or-break step! Begin by taking your sliced or chopped zucchini and placing it into a colander set over a bowl. This setup allows excess liquid to drain away easily. Sprinkle 1/2 teaspoon of the salt evenly over the zucchini. The salt helps draw moisture out through osmosis. Let this sit for at least 20-30 minutes. You’ll see water collecting in the bowl below – that’s exactly what you want! After letting it sit, gently press down on the zucchini in the colander with your hands or the back of a spoon to squeeze out even more liquid. Finally, transfer the zucchini to a stack of paper towels and pat it dry thoroughly. You want it as dry as possible before adding it to the mix. This dedicated step is the key to a bake that holds its shape and isn’t watery!
Get the Oven Ready: While your zucchini is doing its thing, preheat your oven to 375°F (190°C). Lightly grease a medium baking dish. Butter or cooking spray works well here. Greasing the dish helps prevent the casserole from sticking and makes serving easier.
Whisk the Wet Foundation: In a large mixing bowl, whisk together the 2 large eggs. Whisk them well until the yolks and whites are fully combined – this ensures even distribution and binding. Add the 1/2 cup of heavy cream or milk, the remaining 1/2 teaspoon of salt, the 1/4 teaspoon of black pepper, and the optional 1/4 teaspoon of garlic powder. Whisk everything together until the mixture is smooth and well combined. This liquid mixture forms the base that binds all your delicious veggies and cheese together.
Combine All the Goodness: Now it’s time to bring everything together! Add the drained and thoroughly dried zucchini (give it one last pat with paper towels if you’re unsure!), the cup of corn kernels, the 1/2 cup of plain breadcrumbs or crushed crackers, 1 1/2 cups of the shredded cheese blend (reserve the other 1/2 cup for the topping), and the 2 tablespoons of chopped fresh parsley to the bowl with the wet ingredients. Use a spoon or spatula to gently stir everything together until all the ingredients are evenly distributed and coated in the creamy mixture. The breadcrumbs or crackers will immediately start to absorb some of the moisture, helping to create a nice, firm texture.
Assemble and Prepare for Baking: Pour the entire mixture from the bowl into your prepared, greased baking dish. Spread it out evenly in the dish so it’s roughly the same thickness throughout. Take the reserved 1/2 cup of shredded cheese and sprinkle it generously and evenly over the top of the mixture in the baking dish. This top layer of cheese will melt into a beautiful golden crust.
Bake Until Bubbly and Golden: Place the baking dish into your preheated oven. Bake for 30-35 minutes. You’ll know it’s ready when the casserole is set in the center (it shouldn’t look liquidy when you gently shake the dish), it’s bubbly around the edges, and the cheese on top is melted and has turned a lovely light golden brown color. If your oven doesn’t brown the top as much as you’d like, you can carefully place the dish under the broiler for just 1-2 minutes. Watch it very closely under the broiler, as cheese can go from golden to burnt in seconds!
Rest Before Serving: Once out of the oven, resist the urge to dive in immediately! Let the Cheesy Zucchini & Corn Bake stand for a few minutes (5-10 minutes is perfect) before you serve it. This resting time allows the casserole to finish setting and makes it easier to portion neatly. Garnish with a little extra fresh parsley right before bringing it to the table for a pop of color and freshness.

Tips for Perfect Cheesy Zucchini & Corn Bake Every Time

Making this bake is straightforward, but a few extra tips can take it from great to absolutely perfect!

Don’t Skimp on Zucchini Prep: Seriously, this is the most important step! Salting and drying the zucchini removes a significant amount of water that would otherwise release during baking and make your casserole watery. Give it ample time and pat it really dry.
Experiment with Cheese: While cheddar and mozzarella are a classic combination, feel free to experiment! Gruyere, Monterey Jack, or a mix including a little Parmesan could also be delicious. Just make sure the cheese you choose melts well.
Cracker Choice Matters: Using crushed crackers instead of breadcrumbs can add a lovely buttery or slightly salty note. Graham crackers won’t work here, obviously, but things like Ritz, saltines, or even gluten-free crackers are great options.
Spice It Up (Optional): For a little kick, consider adding a pinch of red pepper flakes to the mixture along with the black pepper.
Add Extra Veggies: Finely diced bell peppers, onions (sautéed briefly), or even chopped spinach (well-drained and squeezed dry) can be added for extra nutrients and flavor. If you enjoy cooking with spinach, you might like our Creamy Chicken Florentine recipe!

What to Serve With This Delicious Bake

This Cheesy Zucchini & Corn Bake is incredibly versatile. It makes a fantastic side dish for a wide variety of main courses. We love serving it with grilled chicken, like our juicy Grilled Chicken Thighs, or alongside simple roasted fish. It’s also a wonderful accompaniment to a classic meatloaf or beef dish. Looking for other side dish ideas? Our Roasted Parmesan Asparagus or Creamy Mashed Potatoes would be delightful additions to your meal!

For a lighter meal, a generous portion of this bake alongside a fresh green salad is perfectly satisfying. It’s also hearty enough to be a vegetarian main dish itself.

Your Cheesy Zucchini & Corn Bake Questions Answered (FAQ)

Got questions? I’ve got answers! Here are some common queries about making this delightful Cheesy Zucchini & Corn Bake.

Can I use frozen zucchini or corn?

You can definitely use frozen corn, just make sure it’s thawed and well-drained. For zucchini, I strongly recommend using fresh. Frozen zucchini tends to release a lot more water, even after salting, and can be difficult to get dry enough for this recipe’s intended non-watery result.

Can I make this ahead of time?

You can assemble the casserole (steps 1-5) and keep it covered in the refrigerator for up to 24 hours before baking. When you’re ready to bake, let it sit at room temperature for about 15-20 minutes before putting it in the oven, and you might need to add a few extra minutes to the baking time.

How should I store and reheat leftovers?

Store any leftovers in an airtight container in the refrigerator for up to 3-4 days. To reheat, you can microwave individual portions, or cover the baking dish with foil and reheat in a 325°F (160°C) oven until heated through, about 15-20 minutes. Reheating in the oven helps the top cheese crisp up nicely again.

Is this recipe gluten-free?

As written, it is not gluten-free due to the plain breadcrumbs or crushed crackers. However, you can easily make it gluten-free by substituting the breadcrumbs or crackers with gluten-free breadcrumbs or crushed gluten-free crackers. The rest of the ingredients are typically gluten-free.

Can I use low-fat milk or cheese?

Using low-fat milk or cheese will result in a less creamy and potentially less flavorful bake. Low-fat dairy products also tend to release more moisture when heated. For the best texture and flavor, I recommend sticking to the heavy cream or whole milk and a good quality cheese blend as specified.
