Savoury Tarte Tatin with Pork Belly and Caramelised Onions

A savoury tarte Tatin takes the French upside-down tart into dinner territory, using the same idea of a caramelised filling finished beneath crisp puff pastry. Here, rich pork belly sits among slow-cooked onions reduced with white wine, cider vinegar, thyme and pepper until glossy, sweet-savoury and deeply savoury. Once turned out, the tart has a burnished onion topping, tender pork and a flaky all-butter pastry base. It is a dramatic but practical dish for sharing, best served warm with something sharp or leafy alongside to cut through the richness.

Why this recipe works

  • Crisp pastry, glossy topping: The tart is baked pastry-side up, then inverted so the crisp puff pastry supports a sticky onion and pork belly topping.
  • Richness kept in check: Dry white wine and apple cider vinegar cut through the pork fat and brown sugar, keeping the caramelised onions savoury rather than cloying.
  • Classic inverted method: Using the tarte Tatin technique lets the onions caramelise against the pan while the pastry bakes separately into a deep golden crust.

Timing notes

  • Rest before flipping: The short rest allows the caramel to settle slightly, making the inversion cleaner and reducing the chance of a runny topping.
  • Serve warm: This tart is at its best soon after turning out, while the pastry is still crisp and the onion topping is glossy.
  • Most of the time is gentle cooking: The active work is manageable, but the onions need patient caramelising and the tart needs a full bake for the best texture.

Ingredient notes

  • Choose all-butter pastry: All-butter puff pastry gives the tart a cleaner flavour and a more delicate, flaky finish than many standard versions.
  • Use skinless pork belly: Skinless pork belly browns and renders more evenly here, giving rich pieces of pork without a chewy layer beneath the pastry.
  • Keep the caramel savoury: The wine and cider vinegar are important for balance. If using water instead of wine, reduce the liquid well and adjust the seasoning to taste.

Common mistakes

  • Crowding the pork: Brown the pork belly in a single layer so it renders properly; overcrowding traps steam and slows down caramelisation.
  • Rushing the onions: Onions should cook slowly until jammy. If they start to catch, lower the heat rather than adding more sugar.
  • Leaving the filling too loose: Reduce the wine and vinegar until the onions are coated in a syrupy glaze before adding the pastry, otherwise the finished tart can turn soggy.

Serving ideas

  • Add something sharp: Serve with bitter leaves, a mustardy green salad or lightly dressed chicory to balance the pork and caramelised onions.
  • Wine pairing: A dry white wine or a light, fresh red works well with the sweet onions, thyme and rich pork belly.

  1. Heat the oven to 200°C (390°F). Cut the pork belly into thick slices, then lightly crush the peppercorns.
  2. Set a cast-iron frying pan over medium heat and add the pork belly in a single layer. Cook for 8 to 10 minutes, turning, until well browned and much of the fat has rendered; transfer to a plate.
  3. Pour off all but about 2 tablespoons of fat from the pan, then add the butter. Slice the onions, add them to the pan with the brown sugar and crushed peppercorns, and cook over medium-low heat for 25 to 30 minutes, stirring often, until deep golden and jammy.
  4. Add the thyme sprigs, then pour in the wine and vinegar. Simmer for 6 to 8 minutes until the liquid reduces to a glossy syrup that coats the onions.
  5. Nestle the pork belly into the onions, arranging it evenly across the pan. Roll the puff pastry to a round slightly larger than the pan, then lay it over the filling and tuck the edges down inside the pan.
  6. Bake for 30 to 35 minutes until the pastry is puffed and deep golden. Rest for 10 minutes so the caramel settles slightly, then carefully invert on to a serving plate and lift off the pan; remove the thyme sprigs before serving.

Recipe notes

Tips

  • For the cleanest flip, choose a serving plate with a slight rim to catch any caramel, and invert in one confident motion.
  • If the onions start to catch while caramelising, lower the heat and stir more often; slow cooking is what makes them sweet and glossy.
  • Pork belly should be cooked until piping hot throughout; if serving anyone vulnerable, avoid undercooking and ensure the centre is fully hot.

Substitutions

  • Replace Dry White Wine with the same amount of water, and reduce for a minute or two longer to concentrate the flavour.
  • Replace Fresh thyme with 1 tsp dried thyme, stirred in when you add the wine and vinegar.
  • Replace Brown sugar with the same amount of honey for a softer, more floral sweetness.

Storage

  • Refrigerate up to 3 days
  • Cool completely, then refrigerate in an airtight container. Reheat on a baking tray in a 180°C (355°F) oven for 12 to 15 minutes until the pastry is crisp again and the filling is piping hot.
