Ingredients You’ll Need

3 medium zucchinis, thinly sliced
2 cups of corn (fresh, frozen, or canned)
1 medium onion, diced
3 large eggs
1 cup shredded cheddar cheese
½ cup grated Parmesan cheese
½ cup all-purpose flour
1 teaspoon garlic powder
½ teaspoon onion powder
1 tablespoon fresh thyme leaves
Salt and pepper to taste
1 cup milk
2 tablespoons butter
¼ cup breadcrumbs (optional)

Step-by-Step Guide

1. Prepare the Vegetables

Start by washing your zucchinis thoroughly. Thinly slice them into rounds, about ¼ inch thick, ensuring they are even to cook uniformly. Dice the onion finely and set it aside. If using fresh corn, cut the kernels off the cob. For frozen corn, thaw it, and if you’re using canned corn, be sure to drain it.

2. Sauté the Onions and Zucchini

Heat a large skillet over medium heat and add the butter. Once melted, toss in the diced onions and sauté them until translucent. Next, add the zucchini slices, cooking for about 5-7 minutes until they soften but still hold their shape. Remove from heat and set aside to cool.

3. Mix the Egg and Cheese Base

In a large mixing bowl, crack the eggs and whisk them thoroughly. Add the milk, garlic powder, onion powder, thyme, and a generous pinch of salt and pepper. Stir in the shredded cheddar and half of the Parmesan cheese. This egg-cheese mixture will create the creamy, cheesy goodness that binds the casserole together.

4. Assemble the Casserole

Preheat your oven to 350°F (175°C). Grease a large baking dish with butter or nonstick spray. Spread a thin layer of the sautéed zucchini and onions at the bottom of the dish, followed by a layer of corn. Repeat this layering process until all the vegetables are used up.

Now pour the egg-cheese mixture over the top, ensuring it evenly coats all the vegetables. If you’d like some extra texture, sprinkle breadcrumbs over the top, followed by the remaining Parmesan cheese.

5. Bake to Perfection

Place the casserole in the preheated oven and bake for 35-40 minutes, or until the top is golden brown and bubbly. You’ll know it’s ready when the center is set and doesn’t jiggle when you shake the dish gently.

For an extra crispy top, turn on the broiler for the last 3-5 minutes of baking, keeping a close eye on it to prevent burning.

6. Serve and Enjoy

Once your casserole has baked to perfection, remove it from the oven and allow it to cool for 5-10 minutes before serving. This allows the flavors to meld and the casserole to set, making it easier to cut into neat slices. Garnish with a few fresh thyme leaves for an extra pop of color and flavor.

Recipe Variations

One of the best things about this Corn and Zucchini Casserole is how versatile it is. Here are some fun variations you can try to keep things interesting:

Add Protein: Make this a complete meal by adding diced cooked chicken, crumbled bacon, or even cooked ground beef into the mix.
Go Low-Carb: Swap out the flour for almond flour or another low-carb substitute if you’re watching your carb intake.
Extra Veggies: Feel free to toss in some bell peppers, mushrooms, or spinach for an extra dose of vegetables.
Spicy Kick: If you like a little heat, add chopped jalapeños or a sprinkle of red pepper flakes to the egg mixture.

Tips for the Perfect Casserole

Pat Dry the Zucchini: Zucchinis contain a lot of water, which can make your casserole soggy if not dealt with properly. After slicing, sprinkle the zucchini rounds with a little salt and let them sit for 10 minutes. Pat them dry with a paper towel to remove excess moisture.
Use Fresh Herbs: Fresh thyme or basil can elevate the flavor profile of this dish, so don’t skip this step. If you only have dried herbs on hand, reduce the amount by half.
Even Layers: For the best texture and flavor distribution, make sure to layer the zucchini and corn evenly in the dish. This ensures every bite has a bit of both veggies and plenty of cheesy goodness.

Storage and Reheating

This casserole is great for leftovers! Store any extra portions in an airtight container in the refrigerator for up to 4 days. To reheat, simply pop a slice in the microwave or warm it up in the oven at 300°F for 10-15 minutes until heated through.

If you want to freeze this dish, prepare the casserole as directed but stop before baking. Cover it tightly with aluminum foil and freeze for up to 3 months. When you’re ready to eat it, bake directly from the freezer, adding an additional 10-15 minutes to the cooking time.

Final Thoughts

Corn and Zucchini Casserole is a versatile, crowd-pleasing dish that’s perfect for any occasion. Whether you’re serving it as a side at a family dinner or bringing it to a potluck, this casserole is guaranteed to impress. The combination of fresh vegetables, cheese, and a golden, crispy topping is sure to make this recipe a staple in your kitchen.
