Garden Zucchini, Corn & Feta Crustless Quiche with Fresh Basil
There are recipes that feel like they were made for a beautiful summer morning, and this Garden Zucchini, Corn & Feta Crustless Quiche is one of them.
It’s light but satisfying, full of tender zucchini, sweet corn, salty feta, and fresh basil. Everything is held together by a creamy, savory egg mixture that bakes into a soft, golden quiche without any pastry crust.
I first made this after coming home with more zucchini than I knew what to do with.
A neighbor had given me a few from their garden, and I already had fresh corn and basil in the kitchen.
I didn’t want to make another complicated dinner, so I decided to turn everything into a crustless quiche.
I sautéed the zucchini, whisked the eggs, crumbled in some feta, added the corn and basil, and poured everything into a baking dish.
While it baked, the kitchen smelled absolutely wonderful.
When I sliced into it, the center was soft and creamy, the edges were lightly golden, and every bite had a little sweetness from the corn and a salty burst of feta.
We ate it warm that evening, and the leftovers disappeared the next morning.
Now it’s one of those recipes I love making when I want something homemade, fresh, and easy enough for breakfast, lunch, or dinner.

How to Make Garden Zucchini, Corn & Feta Crustless Quiche
Step 1: Preheat the Oven
Preheat your oven to 190°C (375°F).
Grease a 9-inch pie dish or similar baking dish with olive oil or cooking spray.
Step 2: Cook the Zucchini
Heat the olive oil in a skillet over medium heat.
Add the diced zucchini.
Cook for approximately 4–5 minutes, stirring occasionally, until the zucchini begins to soften and lightly brown.
Add the minced garlic and cook for another 30 seconds.
Remove from the heat.
Step 3: Prepare the Egg Mixture
In a large bowl, whisk together:
Eggs
Milk or half-and-half
Salt
Black pepper
Red pepper flakes, if using
Whisk until smooth.
Don’t overbeat the eggs—you simply want everything combined.
Step 4: Add the Vegetables and Cheese
Add the cooked zucchini, corn, feta, Parmesan, and fresh basil to the egg mixture.
Gently stir everything together.
Save a little feta and basil for the top if you want a prettier presentation.
Step 5: Pour Into the Dish
Pour the mixture into your prepared baking dish.
Spread everything evenly.
Sprinkle a little extra feta and Parmesan over the top.
Step 6: Bake
Bake uncovered for approximately 35–40 minutes.
The edges should be lightly golden, and the center should be set but still have a very slight jiggle.
Don’t overbake it.
The quiche will continue to firm up as it cools.
Step 7: Rest Before Serving
Remove the quiche from the oven.
Let it rest for approximately 10 minutes.
Scatter fresh basil over the top.
Slice and serve warm.
My Best Tips
Don’t Skip Sautéing the Zucchini
Zucchini contains a lot of water.
Cooking it first helps remove excess moisture and gives it better flavor.
Drain Frozen Corn
If you’re using frozen corn, thaw and drain it first.
Extra water can make the quiche softer than you’d like.
Don’t Overbake
The center should be just set.
If you bake it until it’s completely firm and dry in the oven, it may become rubbery as it cools.
Let It Rest
Giving the quiche a few minutes to cool makes it easier to slice cleanly.
Can I Use Frozen Zucchini?
Fresh zucchini is best.
Frozen zucchini tends to release a lot of water, which can make the quiche watery.
If using frozen zucchini, thaw it completely and squeeze out as much moisture as possible.
Can I Use Canned Corn?
Yes.
Drain it thoroughly before adding it to the egg mixture.
Fresh summer corn is wonderful when available, but canned or frozen corn works perfectly well.
Can I Make This Without Feta?
Absolutely.
Try:
Goat cheese
Ricotta
Cheddar
Monterey Jack
Mozzarella
Parmesan
Feta gives the dish a particularly delicious salty contrast to the sweet corn.
Can I Add Meat?
Yes.
Try adding:
Crispy bacon
Diced ham
Cooked sausage
Shredded chicken
Smoked turkey
Make sure any meat is already cooked before adding it.
Can I Make It Vegetarian?
Yes.
The recipe as written is vegetarian.
For an even more vegetable-packed version, add spinach, mushrooms, bell peppers, or cherry tomatoes.
Can I Make This Keto?
Yes, with one consideration: corn contains more carbohydrates than many keto vegetables.
For a lower-carb version, reduce or omit the corn and add extra zucchini, spinach, mushrooms, or broccoli.
The eggs, zucchini, feta, and basil are naturally low in carbohydrates.
Can I Make This Dairy-Free?
Yes.
Use your preferred unsweetened dairy-free milk and a dairy-free feta-style cheese.
The texture will vary slightly depending on the substitute.
Can I Make This Gluten-Free?
Yes.
There is no flour or traditional crust in this recipe, so it is naturally gluten-free.

Can I Make This Ahead?
Absolutely.
This is one of those recipes that is actually wonderful the next day.
Bake it completely, let it cool, cover it tightly, and refrigerate.
You can serve it cold, at room temperature, or gently reheated.
Storage
Store leftover quiche in an airtight container or tightly covered baking dish in the refrigerator for up to 4 days.
How to Reheat
For individual slices, microwave for approximately 30–60 seconds.
For a better texture, reheat in a 175°C (350°F) oven until warmed through.
Can I Freeze It?
Yes.
Allow the quiche to cool completely.
Cut it into individual slices and wrap them well before placing them in a freezer-safe container.
Freeze for up to 2 months.
Thaw overnight in the refrigerator before reheating.

Avocado

Frequently Asked Questions
Why is my crustless quiche watery?
Zucchini and corn both contain moisture. Sauté the zucchini first, drain frozen or canned corn well, and avoid overloading the quiche with watery vegetables.
Can I skip cooking the zucchini first?
You can, but I don’t recommend it. Sautéing removes moisture and gives the zucchini better flavor.
How do I know when the quiche is done?
The edges should be lightly golden and the center should be set with just a slight jiggle.
Can I use a different baking dish?
Yes. A 9-inch pie dish, 8×8-inch baking dish, or similar-size oven-safe dish will work.
The baking time may change slightly depending on the depth of the mixture.
Can I use egg whites instead of whole eggs?
Yes, although the quiche will be lighter and less rich.
Can I make mini versions?
Absolutely.
Pour the mixture into greased muffin tins and bake until the centers are set, usually around 18–25 minutes depending on the size.
Final Thoughts
This Garden Zucchini, Corn & Feta Crustless Quiche is one of those recipes that makes me appreciate simple seasonal ingredients.
There’s nothing complicated about it.
Just eggs, zucchini, sweet corn, salty feta, Parmesan, garlic, and fresh basil.
But once they’re baked together, something special happens.
The zucchini becomes tender.
The corn adds little bursts of sweetness.
The feta melts just enough to become creamy in some places while staying deliciously salty in others.
And the fresh basil gives everything that bright, summery finish.
I love making this on weekends when breakfast can take its time.
I’ll often bake it in the morning, slice it while it’s still warm, and leave the rest in the refrigerator for an easy lunch later.
It’s also perfect for those evenings when you don’t want a heavy dinner but still want something satisfying.
And if you have a garden overflowing with zucchini, this recipe gives you one more delicious reason not to waste a single one.
Serve it warm with a simple salad.
Serve it cold for lunch.
Pack a slice for a picnic.
Or stand at the refrigerator the next morning and eat a cold piece straight from the container.
No judgment here.
Sometimes the leftovers are even better. 🌿🥒🌽🧀
