Rustic Tomato Zucchini Tart is filled with caramelized onions, garden fresh zucchini, tomatoes and Parmesan cheese on top of pastry dough. Let me show you how to make another one of my easy zucchini recipes that’s perfect for a light dinner or fancy enough for company.
I have a delicious recipe for you today! The inspiration for this Tomato Zucchini Tart came after a walk through our garden. Our garden is producing nicely this year. Which makes me very happy.
I couldn't wait to use both the tomato and zucchini and made this delicious Rustic Tomato Zucchini Tart for dinner. It was the perfect light summer evening recipe to serve with a large tossed salad.
Here are the tomatoes that made such a delicious tasty recipe. Aren't they so cute? I know, I know, tomatoes aren't really "cute."

- Butter
- Onions, sliced thin
- Zucchini, sliced thin
- Grape tomatoes, about 2 cups
- ¼ cup Parmesan cheese
- 1 cup Mozzarella cheese
- Basil
- Parsley
- 1 egg mixed with a little milk
- Single recipe pie crust; homemade or store bought.
Instructions
Using either a very sharp knife or a mandoline slicer, slice the zucchini into rounds. For best results, you want the zucchini slices to be thin and evenly sliced as possible. Which is why I recommend using a mandoline slicer.
Slice the grape tomatoes in half, lengthwise. That way they won't roll around on the tart when you're moving it into the oven.
Set the vegetables aside as you prepare the onions.
Make sure you check out my post on how to make an easy pie dough recipe. I have step by step photo instructions too!
Roll out the pie dough and fit it into an rectangle baking tray; set aside. Heat the butter in a heavy skillet. Then add the sliced onions and cook until they are soft and golden brown; about 20 minutes.
Spread the mozzarella cheese on top of the pie dough. Add the cooked onions on top of the cheese. Arrange the sliced zucchini and then the tomatoes on top.
Arrange the zucchini and tomatoes on top and sprinkle with the Parmesan cheese and herbs.
Brush the beaten egg and milk mixture over the entire pie crust. Bake in a preheated 425 degree oven for about 20 minutes or until the crust is golden brown.
Frequently Asked Recipe Questions
You'll know a zucchini is no longer fresh when you slice into it and the inside flesh is stringy. Also the skin will be wrinkled. Do not eat the zucchini if it is moldy.
I like to roll pie dough out on parchment baking sheets. That way I can easily move the pie dough to the appropriate pan by simply lifting the edges of the parchment paper.
If you find your pie dough is breaking apart and crumbling, it's probably too dry. You can fix this problem by lightly sprinkling the dough with chilled cold water over the surface and then working the water into the dough.

They say great minds think alike, as I recently made a Tomato and Cheese Crostata! Very similar to your recipe here and I didn't even see the Pioneer Woman's episode with her Tomato Tart. Crostata or tart, as either one definitely makes for a delicious and light summer or fall-inspired meal 🙂
