How to Make Zucchini and Corn Bake Recipe

Preheat oven: Set to 375°F (190°C) with rack in center. Allow full heat-up for even, golden browning. This ensures your veggies get tender while the cheese topping crisps perfectly.

Combine ingredients: In a large bowl whisk eggs, sour cream, salt, and pepper. Gently fold in zucchini, corn, and sautéed onion mixture until evenly coated.
Assemble bake: Grease an 8×8-inch baking dish. Transfer mixture, smoothing top with back of a spoon. Sprinkle shredded cheddar and parmesan evenly for a crispy, golden crust.
Bake to golden: Place dish in oven and bake 35–40 minutes, until edges bubble and top turns golden brown. Rest 10 minutes before slicing for clean servings.

Zucchini and Corn Bake Recipe FAQs

I recommend using medium-sized, firm zucchini with smooth skins and no soft spots. These will hold their shape well and avoid excess moisture, which keeps your bake from getting soggy.

How long can I store leftovers of this zucchini and corn bake in the fridge?
You can safely store leftovers in an airtight container for up to 3 to 4 days in the refrigerator. Make sure it’s cooled completely before sealing to maintain freshness and flavor.

Can I freeze the zucchini and corn bake, and if so, how should I do it?
Absolutely! Freeze this bake for up to 3 months. Here’s how: let it cool fully, then wrap tightly in plastic wrap or aluminum foil to prevent freezer burn. Place the wrapped bake in a freezer-safe container or zip-top bag. When ready to eat, thaw overnight in the fridge, then reheat in a preheated 350°F oven for 15-20 minutes until warm and bubbly.

What if my zucchini release too much water during baking? How can I fix that?
Too much moisture can make the bake runny. To prevent this, pat zucchini dry with paper towels before mixing. If it still seems watery, try baking uncovered to help moisture evaporate, or add a tablespoon of breadcrumbs to absorb excess liquid. These little tweaks save your crisp, cheesy topping from becoming soggy!

Are there any allergy considerations with this recipe?
This zucchini and corn bake contains dairy (cheddar, parmesan, sour cream) and eggs, so it’s not suitable for those with dairy or egg allergies.

Always double-check ingredient labels for hidden allergens.
