Zucchini pie is a riff on the classic Southern tomato pie, with a cheesy sweet onion base topped with thin rounds of zucchini, all baked up in a buttery crust. The effect is lovely and the flavor is pure summer.

zucchini pie celebrates summer’s bounty
Southern country cooking is straightforward, seasonal, and delicious. In summer it’s all about fried green tomatoes, cornmeal biscuits, barbecue, berry cobblers and of course, tomato pie. My zucchini pie is a nod to that traditionโฆIf you’re lucky enough to be overloaded with zucchini this summer, or if you picked up a few prized specimens at the farmer’s market, allow me to introduce you to this amazing zucchini tart. It puts gorgeous summer squash center stage, supported by a rich, onion-y and cheese-y base and topped with more cheese and fresh thyme. A savory zucchini pie is the perfect lunch, starter, or delicious vegetarian main course.

what you’ll need to make zucchini pie
- zucchini ~ look for slender uniform zucchini so your slices will be more or less the same size.
- onion ~ very thinly sliced, I love to use a sweet onion like Vidalia. If you can’t find Vidalia, use a generic sweet onion, they’ll be right next to the regular onions in your produce section.
- mayonnaise makes for a super creamy, rich base. It kind of tastes like your favorite onion dip! Make your own homemade mayo, or use Duke’s for best southern flair.
- shredded sharp cheese ~ I used cheddar but any sharp cheese will work, and you can really customize this tart with different cheeses. Sharp or aged cheeses will give you the best flavor.
- salt and fresh cracked pepper ~ this is all the seasoning this simple pie needs.
- a single pie crust ~ you can make it from scratch, or use a readymade crust. I love my easy Food Processor Pie Crust.
layer up your savory zucchini pie
- Line a shallow pie plate or tart pan with pastry crust and pre-bake.
- Thinly slice the onions and lay them over the par baked crust.
- Blend the mayo and cheese and spread it over the onions.
- Top with overlapping, concentric circles of thinly sliced zucchini.
- Finish with a light brushing of olive oil, and another handful of cheddar cheese, and bake until bubbling and golden. You can run it under the broiler at the end to get more color, but be careful not to burn.
tips and faqs for zucchini pie
You can slice your zucchini with a sharp knife, but I love to use my mandoline slicer to make quick work of the job. The mandoline insures perfectly even slices at a precise thickness. It’s important to get the zucchini thin for this pie so it has a chance to cook through. Thin slices won’t become watery, either.
You can use golden zucchini for a pretty variation, but I wouldn’t use summer squash because it’s not uniform in shape and your slices will be different sizes. You might experiment with a mix of zucchini, golden zucchini, and slender eggplant. Remember, don’t peel your veggies, the colorful peels are pretty and delicious!
Yes, you can use a refrigerated crust, just it it into your tart pan. If you want to use a frozen crust, choose a shallow crust ~ a deep dish will be too deep for this pie.
Pre baking the crust helps keep it from getting too soggy after the filling goes on. Another trick is to sprinkle about a teaspoon of breadcrumbs (Panko crumbs work well) over the crust before adding the filling. The crumbs help absorb excess moisture for a sog-free zucchini pie.
Always start from the outside, and overlap the slices fairly tightly because they will shrink as they cook. Do a complete ring around the edge, then do another one, again overlapping slightly. The overlap insures you get complete coverage on your pie, even after baking.
what to serve with savory pies
This zucchini pie is super versatile, and can go from brunch to lunch, and dinner. I like to serve it with some sort of salad. A simple mixed green salad would be great, but if you want to take it up a notch, I’ve got lots of inspiration on the blog:
Zucchini Pie
Equipment
- 9 inch tart pan with removeable bottom
- mandoline slicer optional but handy, buy it here.
Ingredients
crust
- 4 ounces unsalted butter, melted
- 1 1/2 cups all purpose flour
- 1 Tbsp sugar
- 1 Tbsp cornstarch
- 1 tsp salt
filling
- 3 slender zucchini, sliced very thinly on a mandoline
- 1/2 medium sweet onion, sliced paper thin on a mandoline
- 1 cup sharp cheddar cheese, Gouda, Gruyere, Parmesan, Asiago, or a mix
- 1/3 cup mayonnaise, I love Duke's
- 1 pinch black pepper
- fresh thyme leaves
garnish
- 2 Tbsp cheddar cheese
- 2 Tbsp Ritz cracker crumbs
Instructions
- Preheat oven to 350ยฐF.
for the crust
- Toss the flour with the sugar, cornstarch and salt and then drizzle in the melted butter until the mixture becomes crumbly. Make sure all the flour gets moistened. Pat the crust into a 9 inch tart pan with a removable bottom. Press it up the sides of the pan. Prick the bottom of the dough all over with a fork. Bake for 12 minutes. Set aside.
for the filling
- Put a layer of onions on the bottom of the crust. Mix the cheese and mayo and spread it over the onions. Top with the zucchini, layering them in a spiral pattern.
- Sprinkle with salt and fresh cracked black pepper. Top with the cheese and the cracker crumbs.
- Tent loosely with foil and bake for 20-25 minutes until the cheese is bubbling and browned. If necessary you can run it under the broiler at the end for more color.
- Serve hot with a sprinkle of fresh thyme.
Notes
- Use young slender zucchini and make sure you slice it very thinly.
- I went easy on the cheese because I wanted some of the zucchini to show in the photos, but you can add more if you like.
- Zucchini is by nature bland, so choose a sharp flavored cheese for the topping. Mozzarella is nice and melty, but it doesn’t have enough personality for this dish.
- You could prep this ahead of time and bake when ready.

This was a huge success. My husband and grandsons are NOT fans of zucchini but I mage enough for 8 but cooked it with out the crust as I had roasted Greek potatoes. They all said they would not have a crust. It will become a favourite with roast beef, chicken, lamb and even ham
Thansk Catherine, nice to know it works without the crust!
Zucchini pie was delicious. I used white cheddar. Was simple and quick. Another winner from Great Island.
Love to hear that, thanks Julie ๐
Can’t wait to try this! I’m going to get creative and add some roasted hatch chilies (diced), sub out half the cheddar with pepper jack and use oregano instead of thyme. Serve with a little salsa on the side. =) My mouth is already watering!
I don’t see mayo listed on the recipe. Am I missing something?
It’s in there now, 1/3 cup. Don’t know why it went missing!
This recipe looks amazing, and Iโm on my way to get ingredients now, but I have a question about the zucchini. If it is sliced thinly enough, do you really need to plunge it into the boiling water? Just trying to understand what purpose that serves. Thanks
You can totally use the zucchini raw, it’s fine. The thing the blanching does is actually to reduce some of the excess moisture that will be released by the raw zucchini. But I think you should be fine.
This was awesome! One thing I did different was to put the fresh sprigs of thyme on top of the tart for the last 5 minutes of baking. The thyme leaves get nice and toasty and the aroma fills the kitchen.
One question, the recipe says to divide the cheese but doesnโt tell you how. One cup in the tart and 1/2 cup on top? Sue please tell us how you split the cheese.
I’m thrilled you made this and loved it Myra! I clarified the cheese, it’s one cup in the filling, and the remaining 1/2 cup on top.
We love cooking up zucchini in the summer but had never tried it in a pie before. It was delicious and my boys ate the zucchini without even realizing it was a veggie they won’t eat on its own. Mom win!
What a gorgeous way to cook zucchini – planning to make it for friends this weekend, thanks Sue.
One of the best zucchini pie recipes I’ve seen this year. What a great result! And the instructions seem very easy to follow.
This is perfect as I have a glut of zucchinis at the moment. It looks so pretty!
