Crispy Zucchini Scarpaccia with Sumac Yogurt - Arabicook – Arabic and Western Recipes

Crispy Zucchini Scarpaccia with Sumac Yogurt

This zucchini scarpaccia is thin, savory, and crisp around the edges, with tender zucchini and onion running through the center. It is inspired by the rustic Italian zucchini tart often made when summer squash is abundant, then served here with a cool lemony sumac yogurt for an Arabicook-style finish.

The key to good scarpaccia is not complicated technique. It is moisture control. Zucchini holds a lot of water, so it needs time with salt, a firm squeeze, and a thin spread on the pan. Once baked, the edges become golden and lightly crisp while the middle stays soft enough to slice.

Serve it warm as a baked zucchini appetizer, cut it into small squares for a mezze-style board, or pair it with salad for a simple vegetarian lunch.

Why You’ll Love This Recipe

This crispy zucchini scarpaccia turns basic zucchini into something snackable and satisfying. The batter is light, not cakey, and the cornmeal gives the edges a pleasant crunch.

It is also practical. You do not need deep frying, special dough skills, or complicated shaping. A sheet pan, a bowl, and a little patience with the salting step do most of the work.

The sumac yogurt adds brightness without overpowering the zucchini. It gives each slice a tangy, creamy contrast that works especially well with the olive oil, herbs, and Parmesan.

Ingredients

For the Zucchini Scarpaccia

• 1 1/2 lb medium zucchini, about 680 g
• 1 small yellow onion, thinly sliced, about 120 g
• 1 1/4 teaspoons fine salt, divided
• 1/2 cup all-purpose flour, about 65 g
• 1/3 cup fine cornmeal, about 50 g
• 1/3 cup finely grated Parmesan or Pecorino, about 30 g
• 1 large egg
• 3 tablespoons olive oil, 45 ml, divided
• 1/2 teaspoon black pepper
• 2 tablespoons chopped fresh parsley
• 1 tablespoon chopped fresh mint or oregano
• 1/4 teaspoon Aleppo pepper or crushed red pepper, optional
• 1/4 cup water or reserved zucchini liquid, 60 ml, plus more only if needed

For the Sumac Yogurt

• 3/4 cup plain Greek yogurt, about 180 g
• 1 tablespoon fresh lemon juice, 15 ml
• 1 teaspoon lemon zest
• 1 small garlic clove, finely grated
• 1 teaspoon sumac
• 1 tablespoon olive oil, 15 ml
• 1/4 teaspoon fine salt

Ingredient Notes

Choose medium zucchini if possible. Oversized zucchini can be watery and seedy, which makes it harder to get a crisp result. If using large zucchini, remove the soft seedy center before slicing.

Fine cornmeal is best here. Very coarse polenta can stay gritty in a thin batter. If you want extra crispness, replace two tablespoons of the all-purpose flour with rice flour.

Parmesan adds savory depth and helps the tart brown. Pecorino works too, but it is saltier, so keep the seasoning modest.

Sumac gives the yogurt a tart, lemony flavor. If you do not have it, use a little extra lemon zest and a small pinch of paprika. The flavor will not be identical, but it will still work as a bright sauce.

Equipment

Use a large bowl, a colander, a clean kitchen towel or cheesecloth, a sharp knife or mandoline, parchment paper, and a rimmed sheet pan.

A 13 x 18-inch sheet pan gives the best thin, crisp result. A 9 x 13-inch pan can work, but the scarpaccia will be thicker and softer in the center.

Step-by-Step Instructions

1. Slice the Zucchini and Onion

Slice the zucchini into very thin rounds or half-moons. Aim for even slices so they soften at the same rate. Thinly slice the onion.

Place the zucchini and onion in a colander. Toss with 1 teaspoon of the salt and let stand for 45 minutes.

2. Squeeze Out the Moisture

Transfer the salted zucchini and onion to a clean kitchen towel or cheesecloth. Squeeze firmly over the sink until the vegetables no longer drip heavily.

If you want to use some of the released zucchini liquid in the batter, reserve a small amount before discarding the rest.

3. Prepare the Pan

Preheat the oven to 425°F / 220°C. Line a 13 x 18-inch rimmed sheet pan with parchment paper.

Brush the parchment with 1 tablespoon of the olive oil. This helps the bottom brown and reduces sticking.

4. Make the Batter

In a large bowl, mix the flour, cornmeal, Parmesan, remaining 1/4 teaspoon salt, black pepper, parsley, mint or oregano, and Aleppo pepper if using.

Add the egg, 1 tablespoon olive oil, and the water or reserved zucchini liquid. Stir until you have a thick, spoonable batter. It should coat the vegetables, not run like pancake batter.

5. Fold in the Vegetables

Add the squeezed zucchini and onion to the batter. Fold until the slices are lightly coated and evenly distributed.

If the mixture feels dry and floury, add water 1 tablespoon at a time. Stop as soon as the batter clings to the zucchini.

6. Spread Thinly

Scrape the mixture onto the prepared pan. Press and spread it into a thin, even layer, about 1/4 inch / 6 mm thick.

Drizzle the remaining 1 tablespoon olive oil over the top.

7. Bake Until Crisp at the Edges

Bake for 35 to 40 minutes, rotating the pan once halfway through. The edges should be deep golden, the top should look dry, and the center should be set rather than wet.

If the middle still looks pale and soft, bake a few minutes longer.

8. Cool and Slice

Let the scarpaccia cool on the pan for 10 minutes. This short rest helps it hold together when sliced.

Cut into squares or rectangles.

9. Make the Sumac Yogurt

Stir the Greek yogurt, lemon juice, lemon zest, garlic, sumac, olive oil, and salt until smooth.

Spoon the yogurt onto the side of the plate or drizzle lightly over the slices just before serving.

Expert Tips

Do not skip the salting step. It is the main difference between crisp-edged scarpaccia and a soggy zucchini bake.

Spread the mixture thinner than you think. If it is too thick, the center steams before the edges can crisp.

Oil under the batter matters. The oiled parchment helps the bottom brown instead of staying pale and soft.

Let it cool before cutting. Straight from the oven, the center is more delicate. After 10 minutes, the slices are easier to lift.

Common Mistakes

Using watery oversized zucchini can make the tart heavy. Remove the seedy middle if the zucchini is large.

Adding too much liquid to the batter is another common issue. The batter should lightly bind the zucchini, not surround it in a thick layer.

Underbaking will leave the center damp. Look for browned edges, a dry surface, and a set middle before removing the pan.

Coarse cornmeal can taste gritty in this recipe. Use fine cornmeal for the best texture.

Variations

For an extra-crisp version, replace a small portion of the flour with rice flour.

For more herbs, use parsley with mint, oregano, or basil.

For a spicy version, add Aleppo pepper, crushed red pepper, or a small pinch of chili flakes.

For a cheesier top, sprinkle a little extra Parmesan over the scarpaccia during the last 10 minutes of baking.

For a summer squash version, replace half or all of the zucchini with yellow squash.

Serving Suggestions

Serve zucchini scarpaccia warm or at room temperature with sumac yogurt on the side.

It pairs well with tomato cucumber salad, grilled chicken, fish, lentil soup, roasted vegetables, arugula salad, olives, or a mezze-style platter. For appetizer portions, cut it into small squares and serve with toothpicks or a small bowl of yogurt dip.

Storage

Cool leftovers completely, then store them in an airtight container in the refrigerator for up to 3 to 4 days.

Separate layers with parchment if stacking slices. Keep the sumac yogurt in a separate container so the scarpaccia does not soften.

Do not leave the baked slices or yogurt sauce at room temperature for long periods, especially in warm weather.

Reheating

Reheat slices on a sheet pan at 375°F / 190°C until warmed through and lightly crisp again.

You can also reheat slices in a dry or lightly oiled skillet over medium heat. Avoid the microwave if you want the edges to stay crisp.

Make-Ahead

You can slice, salt, squeeze, and refrigerate the zucchini and onion up to 1 day ahead.

The sumac yogurt can be made up to 2 days ahead and kept covered in the refrigerator.

For the best texture, bake the scarpaccia the day you plan to serve it.

Freezing

Freezing is possible, but not ideal. The zucchini may soften after thawing, and the crisp texture will be reduced.

If needed, freeze baked slices in a single layer until firm, then wrap tightly. Reheat in a hot oven rather than the microwave.

What should the batter look like?

It should be thick and spoonable. It should coat the zucchini slices lightly without pooling around them.
