Tomato Tarte Tatin is a savoury twist on the classic French dessert, traditionally made with apples. This version uses ripe tomatoes, slowly cooked to bring out their natural sweetness while balancing acidity through caramelisation.
Unlike the original sweet tart, this dish leans into a savoury profile, where tomatoes soften and intensify over slow heat. The addition of vinegar and herbs builds depth, making each bite layered rather than one-note.
A French upside-down tart like this works best during the peak tomato season, when produce is naturally juicy and flavourful. It’s a great centrepiece for a relaxed meal, offering crisp pastry on top and rich, jammy tomatoes underneath.
Season the halved tomatoes generously with salt and pepper, ensuring the seasoning reaches the cut surfaces. Let them sit briefly so excess moisture begins to draw out. This helps intensify flavour while cooking and prevents the tart from becoming watery later.

Step 2: Make Caramel Base
Place sugar in a heavy pan over direct heat and let it melt undisturbed until it turns amber. Add red wine vinegar carefully to deglaze, scraping any caramel bits stuck to the base. Stir in garlic, sliced onions, thyme, and parsley, allowing everything to soften and absorb the caramel.

Step 3: Slow Cook Tomatoes
Arrange the tomato flesh side down over the onion mixture. Move the pan to indirect heat, cover, and cook slowly until the tomatoes wrinkle and release juices. This stage deepens flavour, concentrating sweetness while maintaining structure.

Step 4: Arrange For Baking
Transfer softened tomatoes into a buttered pan, placing them cut side up. Spoon the caramelised onion mixture evenly over them. Trim the puff pastry into a round shape and place it over the filling, gently tucking the edges inward.

Step 5: Bake the tart
Place the pan on indirect heat at a higher temperature and bake until the pastry turns golden and crisp. The butter in the pastry will create flaky layers while sealing the filling underneath.

Step 6: Flip And Finish
Allow the tart to cool slightly before flipping it onto a plate. This helps the caramel settle and prevents sticking. Garnish with fresh basil and a light sprinkle of flaky salt for contrast.
It is a savoury version of the classic French upside-down tart, where tomatoes are caramelised and baked under pastry, then flipped before serving.
Yes, you can use an oven. Slow-cook tomatoes at a low temperature, then bake them at a higher temperature to achieve a similar caramelisation and pastry texture.
This usually happens if tomatoes are not pre-seasoned or cooked long enough. Slow cooking helps reduce moisture and concentrate flavour properly.
Yes, but reduce cooking time slightly. Cherry tomatoes release juices faster and caramelise quicker compared to larger plum tomatoes.
Store in an airtight container in the fridge for up to two days. Reheat in an oven to bring back the crispness of the pastry.
