Savoury Tarte Tatin with Pork Belly and Caramelised Onions
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.

Ingredients
Instructions
- Heat the oven to 200°C (390°F). Cut the pork belly into thick slices, then lightly crush the peppercorns.
- 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.
- 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.
- 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.
- 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.
- 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.
