Porchetta con Patate al Forno (Rolled Pork Belly with Roast Potatoes)
Why this recipe works
- Crisp crackling: Starting the roast at high heat helps the skin blister and crisp before the pork finishes more gently.
- Classic herb seasoning: Toasted fennel, garlic, rosemary and lemon zest give the pork its distinctive savoury, aromatic profile.
- Built-in side dish: The potatoes roast in the same tin, soaking up the pork drippings, lemon and herbs as they turn tender and golden.
- Evenly rolled roast: Rolling and tying the pork belly keeps the seasoning enclosed and helps the joint cook into neat, sliceable portions.

Timing notes
- Mostly hands-off: The shaping and seasoning need attention, but most of the total time is oven roasting.
- Rest before slicing: Let the porchetta rest for 15 minutes so the juices settle and the slices hold together cleanly.
- Serve while the skin is crisp: Porchetta is best sliced soon after resting, when the crackling still contrasts with the juicy pork.
Texture tips
- Dry skin is essential: Pat the pork skin very dry before scoring and salting; surface moisture is the main enemy of crisp crackling.
- Score shallowly: Cut through the skin and fat without slicing into the meat, so the seasoning stays inside and the pork remains juicy.
- Finish the potatoes uncovered: If the potatoes need more colour, roast them briefly after the pork comes out so the edges deepen without overcooking the meat.
Ingredient notes
- Use skin-on pork belly: The skin is what creates the crackling, while the belly’s fat keeps the rolled roast rich and succulent.
- Toast the fennel: A brief toast before crushing brings out fennel’s sweet aniseed aroma and makes the seasoning more pronounced.
- Lemon balances the richness: Lemon zest seasons the pork directly, while the juice in the tin brightens the fatty pan juices around the potatoes.
Make-ahead tips
- Prepare the seasoning early: The fennel, garlic, rosemary and lemon mixture can be prepared ahead, then rubbed onto the pork when you are ready to roll.
- Reheat gently: Warm sliced pork and potatoes in a 180°C (355°F) oven until piping hot, keeping the pork covered for most of the time to prevent drying.
- Freeze the pork separately: For the best texture, freeze sliced porchetta without the potatoes and defrost overnight in the fridge before reheating.

Ingredients
Instructions
- Take the pork belly out of the fridge 30 minutes before cooking. Pat it dry well, then score the skin in a tight crosshatch, cutting through the skin and fat but not into the meat. Preheat the oven to 220°C (430°F).
- Toast the fennel seeds in a dry pan for 1 minute until fragrant, then crush them lightly. Finely grate the garlic, strip and chop the rosemary leaves, and finely zest the lemon. Mix the crushed fennel, garlic, rosemary, lemon zest, black pepper and 12 g of the fine sea salt into a paste.
- Turn the pork belly meat-side up and rub the seasoning paste all over the meat. Roll it up tightly into a neat log, keeping the skin on the outside, then tie securely at 2 to 3 cm intervals with kitchen string. Rub the skin with the olive oil and the remaining 6 g fine sea salt.
- Halve any larger potatoes so they are a similar size, then toss them in the roasting tin. Squeeze in the lemon juice and add any remaining lemon halves to the tin, then scatter over any leftover rosemary sprigs. Sit the porchetta on top of the potatoes, seam-side down.
- Roast for 30 minutes at 220°C (430°F) to start crisping the skin. Reduce the oven to 160°C (320°F) and roast for 75 to 85 minutes more, turning the potatoes once or twice, until the pork reaches 70°C (160°F) in the centre and the potatoes are tender. If the skin needs more colour, increase the oven to 220°C (430°F) for the final 10 minutes, watching closely.
- Transfer the porchetta to a board and rest for 15 minutes. Toss the potatoes in the tin juices and roast for 10 minutes more if you want them deeper golden. Slice the porchetta and serve with the potatoes and the lemony pan juices.
Recipe notes
Tips
- For the crispest crackling, make sure the pork skin is very dry before salting, and keep the score marks shallow so the seasoning stays on the meat side.
- Use a thermometer for accuracy: aim for 70°C (160°F) in the centre, then let carryover heat finish the job during the rest.
- If serving anyone who is pregnant, elderly, or immunocompromised, cook the pork to 75°C (167°F) and rest as directed.
Substitutions
- Replace Fresh rosemary with fresh thyme for a softer, more floral herb note.
- Replace Lemon with lime for a sharper citrus edge.
Storage
- Refrigerate up to 3 days
- Cool leftovers quickly, then refrigerate in a sealed container. Reheat sliced pork and potatoes in a 180°C (355°F) oven until piping hot; keep the pork covered for most of the reheating to prevent drying, then uncover briefly to re-crisp the skin. Freeze sliced pork (without potatoes for best texture) for up to 2 months and defrost overnight in the fridge before reheating.
