Common Questions Answered
How do I choose the best zucchini for this bake?
Go for medium-sized, firm zucchini with vibrant green skin and no blemishes. Avoid larger zucchini since they tend to be watery and not as flavorful.
What is the best way to store leftovers of the Zucchini Corn Tomato Bake?
Keep leftovers in an airtight container in your fridge for up to 3-4 days. Reheat them in the oven at 350°F (175°C) to keep your cheese gooey and crust crisp.

The most frequent problem is a soggy bottom. To avoid this, briefly sauté your zucchini to release some moisture before mixing it in.
