My obsessions-Italy and Cooking

A Winter Tomato Tart

I’m a tomato snob-I admit it. Even though we still have tomatoes for sale at our local farmers’ market, I just can’t bring myself to buy them. The taste does not compare with a real summer tomato. There is a way to get around this and that’s to roast the tomatoes. I’m meeting with friends to spend some time practicing our Italian and decided to serve this tart made with plum tomatoes. Drizzled with olive oil and baked in a buttery shell with a filling of carmelized onions and gorgonzola cheese, these tomatoes will make you forget that it’s winter!


1-1/2 cups all-purpose flour
1/2 teaspoon salt
1 stick (8 ounces) plus 1 tablespoon cold unsalted butter
About 1/4 cup ice water

In a bowl toss flour with salt. Cut in the butter until the mixture resembles coarse meal. Using a fork, stir in the ice water by tablespoons until the dough holds together when pressed. Sprinkle in more water if needed. Flatten the dough into a disk, wrap well and refrigerate for at least 15 minutes before rolling out.

Tart Filling

2-1/2 pounds yellow onions, coarsely chopped
6 sprigs freshly thyme leaves
1/4 cup extra virgin olive oil
Salt and fresh ground pepper
1 tablespoon minced fresh rosemary
3 ounces Gorgonzola cheese
1 pound plum tomatoes, sliced crosswise 1/3″ thick
1 egg beaten

In large saute pan onions in 3 tablespoons olive oil over very low heat until the onions are light brown. Season with salt and pepper and add 2 teaspoons fresh rosemary. Let cool.

Preheat the oven to 400 degrees. Roll out dough on a lightly floured board to a 14″ circle. Spread the onions over the dough, leaving a 2″ border. Crumble the cheese over top and overlap the tomatoes in a ring. Season with salt and pepper, then drizzle with remaining olive oil and sprinkle with fresh thyme and rosemary. Fold up the dough and pleat the border. Brush the dough with beaten egg.

Bake until the crust is golden, about 35 minutes. Can be served hot or at room temperature. Serves 4-6 as a main course or 8-10 as an appetizer.

I’ve been making this for years, adapted from an old Food & Wine recipe.

  1. Oh my. That looks absolutely tantalizing! I will have to give this a try.

  2. Oh YUMMY! I especially loved this when I read the part where it said caramelized onions and gorgonzola cheese. Will have to try this one, and soon!

  3. Can’t wait to try this!

  4. Gervase, Rowena and Gigi-you won’t be disappointed! I’m getting ready to have a little leftover slice with a glass of wine.

  5. This sounds really good-do you think you could substitute another type of cheese-I am not a big gorgonzola fan?

  6. Linda, let us know if you try it with the feta. I’m not a big Gorgonzola fan either.

  7. Just getting back to you on the tart…

    AWESOME! Can’t wait to get to the market again for some tomatoes. Gotta make this again!!

  8. This one is a must try. What a photo!

  9. Ooh, does this ever look good. I love rustic tarts (mostly because I always do an awful job on pie crust so they never look ‘perfect’). The tomatoes, gorgonzola and carmelized onion? mmmmmmmmm………

  10. Rowena-I’m so happy that you tried it and were as happy as I always am with this!

    Choosy Beggar and Casalba-it really is as tasty as it looks!

  11. Oh My….does that look wonderful. My husband loves tomatoes. He actually eats them with every meal including breakfast….Can I substitute with Assiago cheese instead of using gorgonzola??

  12. Sue-yes, go ahead and use assiago-it should be really tasty!

  13. wow! this looks wonderful!!! i must try it.

  14. This looks delicious. I just did something similar with a tart–I agree, oven roasting or baking the tomatoes is great in the winter months–combined with fresh herbs and flavorful onion is a perfect meal.

  15. I have been meaning to get on here and share that I made this at Easter and it was the best thing I’ve made this year and I have been craving it all summer, so I’m making it again today. BTW, I made it with feta. Yummy!
