What to do with a boatload of zucchini? Scarpaccia, of course. This Italian flatbread emerges from the oven crisp at the edges, but soft and creamy inside. I truly could eat this entire pan alone in one sitting. I have faith you can, too 💪

Scarpaccia is a rustic “flatbread” originating from Tuscany, made mostly of zucchini and onions, bound together by a batter made of cornmeal, flour, grated parmesan, spices, and water. Spread onto a sheetpan, it bakes into a thin layer of utter goodness, irresistibly crisp at the edges, creamy in the center.
I find it nearly impossible to stop eating.
Like so many Italian classics, there are as many ways to make Scarpaccia as there are to make carbonara or any of the the other beloved pastas: some go heavy on the cornmeal, others on the polenta; some call for eggs, others for heaps of parmesan; some call for sautéing the vegetables, others for salting.
The key to success — defined by a crisp, not soggy texture — is to remove as much of the moisture from the zucchini as possible. This is achieved by either cooking it, or salting it. I prefer the salting method as I find it leads to a crisper product. What’s fun about this particular recipe is that after you remove as much water from the zucchini as you can, you save it and use it in the batter itself. Nothing goes to waste.
This salting, draining, and squeezing of the zucchini is the hardest part of the recipe. Everything else is child’s play: whisk together a handful of dry ingredients, add the zucchini water, fold in the vegetables, spread into a pan, bake until crisp.
Friends, I’ve never been to Tuscany, and I generally don’t have wanderlust, but I’m finding this dish is making me want to jump on a plane and never look back. Alas. Until that day arrives, I will be content with thinly slicing ALL the zucchini that crosses my path, cutting up a few tomatoes to serve alongside, drizzling them with the best olive oil I can find, and pouring myself a spritz to wash it all down. I hope you will join me. Cin cin! 🍹
How to Make Zucchini Scarpaccia, Step by Step
First, gather your ingredients:

Next, slice the zucchini into thin rounds. A mandoline makes quick work of this task. As you slice, transfer the zucchini to a colander set in a bowl…

… then season with 2 teaspoons of salt and toss with your hands to distibute.

After 30-60 minutes (or longer), the zucchini will soften as it releases its water into the bowl:

When you are ready to proceed, use your hands to press the zucchini into the colander to squeeze out as much water as possible into the bowl (you’re going to use the water). Transfer the zucchini to a clean towel. Then squeeze as much liquid out of the rounds as you can into the bowl — don’t be afraid to be aggressive.

This step is essential to ensuring the Scarpaccia bakes up crispy in the end.

Transfer the liquid to a liquid measure, then add enough water to get 250 grams total (a heaping cup):

Meanwhile, combine the dry ingredients in a large bowl:

Whisk until blended:

Add the zucchini water:

Then whisk until smooth:

Thinly slice the onion:

Then add it along with the zucchini to the bowl:

Stir with a spatula until blended, then pour the mixture out onto a buttered and cornmeal-dusted sheetpan:

Spread the mixture out into an even layer:

Then brush with olive oil and sprinkle with flaky sea salt:

Transfer to a 425ºF oven, and bake for 40-45 minutes or until browned to your liking:

Let cool in the pan for 5 minutes, then transfer to a cutting board and cut into 12 squares. Serve immediately or at room temperature. Heaven!

Description
What to do with a boatload of zucchini? Scarpaccia, of course. This Italian flatbread emerges from the oven crisp at the edges, but soft and creamy inside. I truly could eat this entire pan alone in one sitting. I have faith you can, too 💪
Recipe adapted from several recipes but with the most influence from Sammy Montgoms.
Notes:
- A mandoline is helpful here for slicing the zucchini and onions thinly. If you have a slicer attachment to a food processor, that will also work. You of course can use a knife, too.
- I love my 12×16-inch Lloyd Grandma Pan for this recipe, but any standard half sheet pan (13 x 18 inches) will work well, too.
- Salt: I always use Diamond Crystal brand. If you are using Morton or fine sea salt, use half as much by volume (or the same by weight). Also, if you are using less than 2 pounds of zucchini, use slightly less salt — I find a teaspoon of Diamond Crystal kosher salt per pound of zucchini works well.
Ingredients
- 2 lbs (907 grams) zucchini or other summer squash (about 4 small-medium)
- 2 teaspoons (7 grams) kosher salt, see notes above
- 3/4 cup (96 g) all-purpose flour
- 1/2 cup (60 g) cornmeal, plus more for sprinkling
- 1/2 cup packed (50 g) grated Parmigiana Reggiana (using the small-grate setting on a box grater)
- 1 tsp (4 g) garlic powder (salt-free)
- 1 tsp (4 g) silk chili, Aleppo pepper, or crushed red pepper flakes
- 1 small yellow or white onion (7 ounces | 200 grams pre-trimming), peeled and thinly sliced
- Butter for greasing the pan
- 2 tablespoons extra-virgin olive oil
- Flaky sea salt
Instructions
- Set a colander inside a large bowl.
- Using a mandoline or a knife, thinly slice the zucchini. The zucchini should be very thin but not paper thin — you should be able to fold each round in half, and it will bend. Transfer the zucchini to the colander, and season with the salt. Toss to distribute, then let it drain. Ideally, allow the zucchini to drain for at least one hour. I have gotten away with less time, and I have also allowed it to drain for over 4 hours.
- Once the zucchini has drained, use your hands to press it hard into the colander to squeeze out as much water as possible into the bowl (you’re going to use the water). Lay a large clean tea towel on a work surface. Transfer the zucchini to the towel. Wrap it up into a beggar’s purse, then wring it out over the bowl to extract as much water from the zucchini as possible — don’t be afraid to be aggressive. Transfer the liquid to a liquid measure, reserving the bowl. Add enough water to the liquid measure to get 1 heaping cup (250 grams). Set aside. Dry out the reserved bowl.
- Preheat the oven to 425ºF.
- In the reserved bowl, whisk together the flour, cornmeal, garlic powder, silk chili, and parmesan. Add the 1 cup (250 grams) of zucchini water to the bowl, and whisk until you have a pancake-like batter.
- Add the zucchini and sliced onion, and using a spatula, fold the vegetables into the batter — it will feel like mostly vegetables with just enough batter to coat them.
- Butter a 13×18-inch sheet pan or a 12×16-inch Grandma pan (see notes above) with softened butter. Sprinkle with 2 tablespoons cornmeal, then shake and rotate the pan to distribute it evenly.
- Spread the zucchini mixture into the pan, and use your hands to spread it evenly, pressing it down into a thin layer. Pour the two tablespoons of olive oil into a small dish, then brush it evenly over the top. Sprinkle with flaky sea salt.
- Transfer to the oven and bake for 40 to 45 minutes or until the edges are crisp. Let cool in the pan for 5 minutes, then transfer to a cutting board and cut into 12 squares.
- Serve immediately or at room temperature.

This was delicious! I added some partially crushed garbanzo beans for some protein.
Yum! Love this idea 🙂
The best!
I have tried many Scarpaccia recipes, always falling short. In the other recipes they called for more zucchini & parchment. I think using less zucchini & no parchment made for a thinner & crisper tart.
Thanks so much for this, will make it again & again.
Great to hear, Dorothy! Thanks so much for writing and sharing your notes 🙂
Made this last night and it was DELICIOUS! I’m sending the recipe to a friend today so she can see how delicious it is for herself.
Great to hear, Claudia! Thanks so much for writing 🙂
Perfect as written!
I added some basil.
Thank you for providing ingredients based on grams! This is so delicious!
Great to hear, Jonie! Thanks so much for writing 🙂
made this tonight with yellow summer squash and it was delicious. super easy too.
So nice to read this, Charrington! Thanks so much for writing 🙂
Saw someone post this exact recipe on Instagram. Didn’t credit you 😬
Argh… it’s so maddening. Happens all the time. I have no idea how to combat it 🙁
I recognized it immediately because I made this a few days ago. I’m sure it is annoying and it’s stealing.
I really look forward to making this! Do you think I could incorporate sourdough discard and feta into this recipe? Thanks for the great recipes and feedback
Cheers from Seattle
I think you could! I have not tried, but this is what I suggested to another commenter:
I think this would be a great candidate for discard! Do you have a scale? Ideally, you would do something like: use 192 grams of discard, no ap flour, and then 154 grams more water. Here’s my math:
192 grams = 96 grams (the weight of the flour) x 2
154 grams = 250 grams (the total weight of the water) – 96
Of course, it will likely take some trial and error to get right.
Let me know if this makes sense!
So your suggestions for substitutions with sourdough discard worked just fine! I was a little concerned at first because it looked more like crêpe batter than pancake batter before I added the zucchini and onions, but after 40 minutes in the oven, it was just as you described: crispy on the outside and creamy on the inside. Trying not to work my way through it solo, but it is tempting!
Great to hear, Catherine! Thanks so much for circling back — several others have been curious about this, too!
This is a question regarding the previous recipe – zucchini flatbread: Could I substitute almond or other GF flour for the flour? Thank you.
I think a gluten-free mix like Cup4Cup would be better than almond flour.
Thank you. I’ve never heard of this brand of flour but will look for it.
I will definitely make this recipe again- I know it will be excellent. Loved the texture & flavor but it was too salty (and I like salt!) Should I have rinsed the zuchinni after letting it sweat? I used kosher salt in the recipe- should I have adjusted for that?
I’m really curious about the salt too. Could the zucchini liquid be diluted?? Hmmmm
Hi Cathy! What brand salt are you using? I have some ideas.
Diamond Crystal. I’m a little salt sensitive, so it could be me.
No, it’s not you… others have experienced the same thing. I’m just trying to figure out how to edit the instructions to make everyone happy … you always can season at the end to taste, but it’s important to have the “batter” seasoned appropriately too. Adding notes soon!
Hi Pam! Sorry about the saltiness — some people have found this one too salty; others have found it underseasoned. Question: what brand kosher salt did you use? I have some thoughts once I know this.
I used a supermarket brand- I think its similar to Morton’s Kosher Coarse Salt and I used Maldon on the top. Any insight would be appreciated because everyone loved it – the salt was the only suggestion to improve it.
Hi! Apologies for the delay here. If it was similar to Morton’s, then it’s twice as salty as Diamond Crystal (the brand I use), which explains the saltiness. Next time, I would use half as much in the batter and maybe hold off on the Maldon on top — you can always add that to taste post-baking.
I made this today, but got distracted and forgot to sprinkle the corn meal over the butter on the baking sheet. It stuck badly, but was still DELICIOUS! I was wondering if I could use a silpat baking mat on the baking sheet that had a butter and corn meal coating? Thanks for a delicious recipe!
Great to hear! Bummer about the sticking though. I think you could use a Silpat, but it might take away from the crispness. I think parchment paper, buttered and sprinkled with cornmeal might be better.
Hi Ali and others – what do you combine this with to make it dinner? Thx.
Hi Lori! I love it with any salad, steamed corn, and something like this baked feta. You could also serve it with some cured meats for a little protein.
This recipe was a blue ribbon winner (it’s State Fair time in Minnesota)! We just can’t stop eating this yummiest side dish. It’s even better the next da,y warmed up in an air fryer. Totally addicting. Thank you for sharing this recipe.
This makes me so happy, Chelle! Thanks so much for writing and sharing your re-heating notes 🙂
This was a super easy and very delicious recipe for zucchini.
Great to hear, Jan! Thanks so much for writing 🙂
I want to make this, but here in France I can’t get corn meal… what can I use instead?
Can you get polenta?
Here to say I made this with cup for cup gluten-free flour tonight and it turned out great! I served it on the side of French lentil soup for dinner
Great to hear, Mary! Thanks so much for writing and sharing this… so helpful for others 🙂
Very salty. I’m going to make it again using less salt.
Sorry to hear about the saltiness, Lee Anne! What brand did you use?
Hi Ali, The “Crispy Oven Fried Eggplant” button takes me to the Zucchini Scarpaccia recipe, which by the way I want to make. But not today. My garden gave me some gorgeous eggplants and I would like to prepare at least one of them with this oven fried method. Maybe it’s my computer. Will you check it? Thanks.
Regards, Jeanne
So sorry, Jeanne!! And apologies for the delay here. Here’s the eggplant recipe: https://alexandracooks.com/2014/09/19/crispy-eggplant-rounds-eggplant-parmesan/
You weren’t kidding!! This is utterly irresistible and better yet- you can make it with gf flour!!!! I used a gf flour blend but next time I’ll try garbanzo flour!
A mandolin is a must and my favorite easy and relatively safe one is OXO brand.
Great to hear, Joanie! Thanks so much for writing and sharing your gf notes — so helpful for others 🙂
I tried this tonight! I have questions about the hydration ratio but its pretty delicious. I’ll make this again
VinaChica
I made this for the first time and it turned out beautifully. I find all of Alexandra’s recipes are well thought out & precise. Definitely delicious with a crisp white wine (preferably a Tuscan white 🤍)
Ps: probably my oven, but I baked this longer than the recipe – about 55 mins
Great to hear, Julie! Thanks for writing and sharing your notes 🙂
this is amazing!! Followed the recipe exactly and it was perfect! It’s a winner!thank you!
Great to hear, Kate! Thanks for writing 🙂
This recipe is truly fantastic, BUT if you scatter a cup or so of fresh cherry tomatoes on top before baking – halved and quickly mixed with a little olive oil and salt first – it adds a bright, sweet additional burst of flavor on some of the bites. We had a number of extra-tiny cherry tomatoes, and I left those whole, only halving the larger, more normal-sized ones. They caramelize perfectly, and seriously take this up another notch, even though it’s perfect as is!
YUM! Love the sound of all of this, Steven! Thanks so much for writing and sharing this idea. Will try 🙂
Yum! This was very tasty and easy enough to put together. Great for using up my garden zucchini! I also like that the recipe has a higher yield, nice as leftovers too.
Ali, I squeezed out my zukes very aggressively, but only had about 1/2 cup of juice. I added water to get to the 1 cup. In the future do you think I could get away with not squeezing, and omit the liquid from the recipe? Have you tried this? Thanks!
Great to hear, Lily! THanks for writing. Unfortunately, non squeezing the squash doesn’t work… I tried. It’s so interesting that you have to salt/extract the zucchini water, only to add it back in. This is where my capacity for science ends 🙂
I have not tried the recipe yet, but it sounds delicious.
I don’t have a mandolin, but wondered if I could shred/grate the zucchini ?
Re: the saltiness issue – you might weigh the salt. I believe what makes one brand saltier than another is the size of the crystals. Weighing it would resolve the difference.
I think shredding will actually work great — as long as you salt, let sit, and squeeze out the liquid, the shredding should be fine — I actually love the idea of using shredded zucchini here.
And you are right about the salt: Morton Kosher Salt is 2x as salty by volume. But if you use the same amount by weight, the salinity is the same… this is my understanding anyway.
I made this today’ substituting fine grain couscous for cornmeal… it worked fine ! I also sprinkled the top with some leftover breadcrumbs mixed with cheese and olive oil, crispy and delicious, thanks so much.
Hi, I made this, loved it, & will make again!
I also have the ‘too salty’ feedback. I did use Diamond Crystal brand as directed.
I had almost a full cup of water from the salted zucchini.
I’ll be interested in your additional notes!
Thanks <3
Would you mind sharing what thickness you’re cutting to on your mandolin slicer? It would remove a bit of guesswork when getting started!!!
This was AMAZING! Putting it into regular rotation for the remainder of zucchini season.
For those wondering about swapping out for a gluten free version: I used the King Arthur 1:1 blend in equal amounts for the AP flour and it was perfection.
Thanks for a great recipe!
