Ingredients You’ll Need to Make Zucchini Corn Casserole
- 2 medium zucchini, sliced or diced
- 2 cups of corn kernels (fresh, frozen, or canned)
- 1 small onion, diced
- 1 cup shredded cheddar cheese (or your favorite cheese)
- 1/2 cup sour cream or Greek yogurt (for extra creaminess)
- 2 eggs, lightly beaten
- 1/2 cup breadcrumbs (optional, for a crispy topping)
- Salt and pepper to taste
How to Make It
- Preheat the oven to 350°F (175°C). Grease a baking dish with olive oil or butter.
- Prepare the veggies – Slice or dice the zucchini and chop up the onion. If you’re using fresh corn, cut it off the cob. If using frozen or canned, just make sure it’s drained and ready to go.
- Mix it all together – In a large bowl, combine the zucchini, corn, onion, cheese, sour cream (or Greek yogurt), and eggs. Add a sprinkle of salt and pepper to taste. If you like a little crunch, mix in some breadcrumbs too.
- Transfer to the baking dish – Pour the mixture into the greased dish, spreading it evenly. If you love a crispy topping, sprinkle extra breadcrumbs and a bit of cheese on top.
- Bake for 25-30 minutes, or until the casserole is set and the top is golden brown.
Tips for the Best Zucchini Corn Casserole
- Use fresh veggies – If you can, use fresh zucchini and corn. It makes a difference in flavor and texture.
- Cheese it up – Don’t skimp on the cheese! Cheddar works great, but feel free to experiment with other types like mozzarella, Monterey Jack, or even pepper jack for a little kick.
- Make it your own – This recipe is super versatile. Add diced bell peppers, fresh herbs, or even some cooked bacon for extra flavor.

Serving Suggestions
This casserole is a fantastic side dish for grilled meats, like chicken or steak. Or, if you want to keep it vegetarian, serve it alongside a fresh salad and some crusty bread. It’s also great for potlucks or as a make-ahead dish for busy nights.
Storing and Reheating
If you have leftovers (which I doubt you will!), store them in an airtight container in the fridge for up to 3 days. Reheat in the oven at 350°F for about 10 minutes, or microwave it if you’re in a hurry.
