Make the most of summer zucchini with this Italian scarpaccia tart! Crispy outer edges and tender interiors make this delicious for a light lunch, snack or side dish.
Using a thin setting on a mandolin, or the slicer on the side of your box grater, finely slice the zucchini (you can use a knife but it takes ages) and the onion.
Sprinkle some flakey sea salt over the zucchini and onion, mix and put into a colander that is balanced over a large bowl. Put something heavy on top of the veggies (I use a plate and some food tins) and leave for an hour or two to extract as much liquid as possible. Squeeze more liquid out in a clean tea towel.
1 kg zucchini, 150 g red onion
Make sure to keep the liquid that is squeezed out!
Finely chop some rosemary and preheat the oven to 200℃/392℉
Now, use the zucchini liquid to make the batter by mixing in all the flour and the cornmeal /polenta.
125 g white flour, 50 g cornmeal
Add a little extra water as needed to make a looseish simple batter.
50 ml water
Miz the zucchini and onion, plus half the rosemary in with the polenta & flour batter.
2 tablespoon fresh rosemary
Sprinkle some polenta over a non-stick baking sheet and brush olive oil all over it. (This prevents it from catching, plus makes a crunchy coating on the bottom.
50 ml olive oil
Spread the zucchini and batter mixture over the sheet. Press down hard with a spatula or put a sheet of parchement paper over the top and press down on that.
The scarpaccia should be even and quite thin, plus you want good contact with the batter and zucchini slices.
Brush with more olive oil, and sprinkle over the rest of the rosemary and some flakey sea salt.
50 ml olive oil, 1 teaspoon flakey sea salt
Bake in the oven for 35-45 minutes or until crispy on the top and edges.
You can cook for longer if you want the scarpaccia to be extra crispy!
Leave to cool completely to help it firm up , then cut into squares in the tin, carefully lift out and eat!
*TIP: It can be a little tricky to remove in one piece from the pan, use a spatula to slide underneath the scarpaccia once it is fully cool to lift it out.
Notes
SUBSTITUTION IDEAS:
Gluten-Free - use chickpea flour in place of the regular white flour to make a simple batter for a gluten-free scarpaccia.
Other Fresh Herbs - use fresh basil, oregano or parsley as well as or instead of the rosemary.
Zucchini Flowers - if you're lucky enough to have fresh zucchini flowers, half them lengthwise and dip in the batter. Press into the top of the scarpaccia for a super pretty effect.
Vegan Parmesan Cheese- Traditional scarpaccia sometimes adds parmesan cheese, add a sprinkle of nutritional yeast or some vegan parmesan to the batter.
Other veggies- very finely slice potatoes, a red bell pepper or carrots for yummy mixed vegetable scarpaccia.
A little spicy- add some red pepper flakes or cayenne pepper to the batter.
Garlicky- choose to add some finely sliced fresh garlic, or sprinkle a generous dash of garlic powder over.
