Why You’ll Love This Rosemary Zucchini Tart

Zucchini is one of those vegetables you’ll see everywhere during summer. From easy vegan zucchini bread to zucchini and potato casserole to baked zucchini fries, there’s not much you can’t do with this versatile veggie! But one way I like to enjoy it in all of its glory is in this vegan rosemary zucchini tart.

This summery tart looks fancy but is surprisingly simple to put together! Fresh zucchini and summer squash are thinly sliced, then layered on top of an easy homemade tart crust. I seasoned the veggies with rosemary for an elegant and garden-fresh flavor profile before I baked the tart to golden brown perfection. 

Besides being an easy yet impressive dish, I love how this zucchini tart recipe showcases a handful of simple ingredients in such a beautiful way. The flavors of the fresh zucchini and summer squash shine through, while the flaky and ‘buttery’ crust is airy and light yet decadent. It’s truly a perfect summer appetizer, side dish, or lunch!

Pair this savory vegetarian tart with my Red Pepper and Sun-Dried Tomato Pesto Pasta, Cherry Tomato Basil Pasta, Vegan Caprese Salad, or Vegan Broccoli Salad for an unforgettable summer meal.

The Ingredients and Substitutes

Please refer to the recipe card for the full list of ingredients and their quantities.

I used vegetable oil in the tart crust but you can use an equal amount of cold coconut oil or vegan butter as a substitute.

Gluten-free? Swap the all-purpose flour for gluten-free all-purpose flour, like Bob’s Red Mill Gluten-Free AP Flour.

You can use store-bought vegan puff pastry or pie dough instead of making the crust from scratch if you’d like. Thaw the dough and roll it into a rectangle with a rolling pin before laying it in the baking pan.

What Else Can I Add to a Savory Vegetable Tart?

  • More herbs: In addition to the rosemary, season the zucchini slices with dried basil, thyme, and/or oregano.
  • Tomatoes: Arrange thinly sliced Roma tomatoes along with the squash.
  • Red chili flakes: Season the zucchini with a pinch of red pepper flakes for a subtle spicy twist.
  • Vegan ricotta: Spread a generous layer of vegan ricotta cheese over the dough before adding the sliced zucchini on top.
  • Vegan cream cheese: Or, instead of the ricotta, add a layer of softened vegan cream cheese.
  • Vegan “egg” wash: Before baking, brush the exposed edges of the dough with a little soy milk to encourage browning.
  • Vegan cheese: Garnish the baked tart with a sprinkle of vegan feta cheese, vegan parmesan, or nutritional yeast (guide to nutritional yeast).
  • Lemon zest: Whisk the lemon zest from 1 lemon into the flour mixture or sprinkle it on top of the tart before baking.

FAQs

Should I salt and drain the zucchini slices before baking?

Zucchini is naturally watery and salting, rinsing, and blotting the slices before baking can help you avoid making a soggy tart. You’re more than welcome to take this extra step if you’d like, but it isn’t necessary.

Should I cover the tart while it bakes?

No, bake it uncovered to help tenderize the vegetables and encourage the dough to turn golden brown.

Can I make the dough ahead of time?

Yes, you can make the dough 2 to 3 days ahead of assembling and baking the tart. Once formed into a ball, wrap the dough in plastic wrap and store it in the fridge. Place it on the kitchen counter for 30 minutes before shaping it on the baking sheet so it can come down to room temperature.

Do I have to blind-bake the crust before adding the zucchini?

No, blind baking the crust isn’t necessary in this recipe because it cooks in the same amount of time as the zucchini.

Pro Recipe Tips

  • Slice the zucchini and squash with a mandoline: Slicing the zucchini and squash with a mandoline will give you the most even slices, which will cook evenly and in the same amount of time.
  • Make sure the slices aren’t too thin or thick: Aim for ⅛ -inch round slices. Any thinner and the zucchini slices will be mushy and overcooked. Too thick and they’ll still be firm by the time the crust is done cooking. 
  • Make the tart in a different pan: You can roll the dough into a circle and lay it in a 9-inch round pan, pie dish, or cast iron skillet instead.
  • Let it cool: Allow the tart to cool in the baking pan for 10 minutes before slicing. It will be piping hot when it comes out of the oven!
