Tomato Tart

As summer ends, the last burst of tomatoes is ripening in my garden. This tart is a great starter course for dinner and should be made right before serving.

As summer ends and the weather gets cooler, the last burst of tomatoes is ripening in my garden. I really like to roast them—they’re not quite as sweet as they were even a month or two ago. Roasting them brings out a sweetness and juiciness that can save even the sourest tomatoes. This tart is a great starter course for dinner and should be made right before serving.


1 pound of ripe tomatoes
1 onion, sliced
2 cloves of garlic, minced
1 tablespoon olive oil (plus more for drizzling)
1 tablespoon butter
1 tablespoon balsamic vinegar (plus more for drizzling)
puff pastry (I used a 1/4 quarter sheet of Dufour’s Puff Pastry and I would recommend cutting it down whatever sheet you get to fit with your pie pan)
parmesan (to finish)
parsley (to finish)
1 egg


  • If you buy frozen puff pastry – like I almost always do – take the dough out of the freezer to defrost in your fridge at least three hours before you plan to bake it.
  • When you are ready to make your tart, preheat the oven to 350 degrees.
  • Sauté the onions and garlic over low heat in the olive oil and butter. Once the onions become translucent, add a teaspoon of salt and a tablespoon of balsamic vinegar. Take them off the heat immediately and set aside.
  • In an 8-inch round pie pan, roll the puff pastry out to match the size of the bottom of pie pan if it doesn’t fit.
  • Place the puff pastry inside the pan and spread out the onion and garlic mixture onto the bottom of the pan.
  • Layer sliced tomatoes or cherry tomatoes (or both!!) on top of the onion mixture.
  • Whisk together an egg and brush it onto the edges of the puff pastry. Sprinkle with salt and drizzle with olive oil and balsamic vinegar.
  • Bake for 30 minutes or until the edges become golden brown. Top with grated parmesan, chopped parsley and serve warm from the oven!
