Ingredients You’ll Need
It may look like a lot at first glance, but these ingredients are simple and carefully chosen to bring out the deep, complex flavors you’re craving. Each component plays a crucial role—from the fennel seeds providing that subtle aniseed aroma, to the rosemary lending evergreen earthiness, and the garlic bringing its pungent warmth. And don’t forget the key role of the pork belly with its perfect balance of meat and fat for that melt-in-your-mouth texture.
- 2.5 kg / 5lb pork belly with skin on (NOT SCORED): The star of the show, providing rich meat with a delicious layer of skin that crisps up beautifully.
- 2 tbsp fennel seeds: Toast these to unlock their fragrant, slightly sweet anise flavor, a classic in Italian-style roast pork.
- 2 tsp black peppercorns: Adds a sharp, peppery bite when ground fresh for the rub.
- 2 1/2 tsp cooking salt / kosher salt: Essential for seasoning and helping to dry out the skin for crispiness.
- 3 tbsp finely chopped rosemary leaves: Fresh or dried rosemary adds piney, aromatic depth.
- 2 tsp red chilli flakes: A little heat that wakes up your palate without overpowering.
- 6 large garlic cloves, finely grated: Brings a warm, savory punch that permeates the pork.
- 2 1/2 tsp cooking salt / kosher salt (for rub): More seasoning to infuse the meat with flavor.
- 2 tbsp olive oil, divided: Used to moisturize the skin and help with roasting.
- 3 tbsp pork belly fat (reserved from roasting): Captured for making a rich, flavorful gravy.
- 1/4 cup plain flour / all-purpose flour: For thickening the luscious gravy.
- 2 cups water: To deglaze the roasting tray and create the gravy base.
- 1/4 tsp freshly ground black pepper: Added to the gravy for subtle spice.
- Salt (if needed): Use to taste, but often unnecessary with all the seasoning in the pork.
How to Make Porchetta with Crispy Skin and Fennel-Rosemary Rub Recipe
Step 1: Prepare Your Spice Rub
Start by toasting your fennel seeds and black peppercorns in a dry pan over medium heat for about 1 1/2 to 2 minutes until the fennel seeds turn lightly browned and aromatic. Grinding these toasted spices into a coarse powder releases their essential oils, providing great flavor depth. Mix this powder with rosemary, chili flakes, garlic, and salt to create a thick, rustic rub that will infuse the pork belly with incredible aroma and taste.
Step 2: Trim and Score the Pork Belly
Pat the pork skin dry carefully with paper towels, an essential step to encourage crispiness later. Trim approximately 3cm of meat from one long edge but keep the skin intact so you can roll the pork nicely. The goal is to ensure the skin fully envelops the meat after rolling. Next, score the meat side in 3cm diamond patterns about 1cm deep, being careful not to pierce through. This allows the rub flavors to deeply penetrate into the flesh.
Step 3: Apply the Rub and Roll
Generously spread your fennel-rosemary paste into all scored cuts and across the meat side with your hands, ensuring every nook is covered. Don’t forget to rub the trimmed meat piece as well, since it will go inside the roll. Lay the trimmed pork piece in the middle, roll the belly tightly, and secure with kitchen twine tied every inch or so. This creates a neat porchetta log promising perfect cooking and presentation.
Step 4: Refrigerate and Dry the Skin
Place the rolled porchetta on a rack over a tray and refrigerate uncovered for 24 to 48 hours. This step is a secret weapon: it intensifies the flavors by infusing the rub and dries the skin’s surface to ensure a super crispy crackling later. A minimum of 12 hours is possible, but the longer, the better your results.
Step 5: Slow Roast the Porchetta
Before cooking, rub the skin with 1 tablespoon of olive oil and a generous sprinkle of salt, rubbing it in for even coverage. Roast the porchetta fat-side up on a rack at 110°C (215°F) for 3 and a half hours. This low-and-slow method makes the meat tender without drying it out, while the skin stays soft, ready to transform into irresistible crackling.
Step 6: Crisp the Skin to Perfection
Once the slow roasting finishes, remove the porchetta and crank your oven up to 240°C (465°F). Transfer your pork to a clean roasting tray, drizzle with the remaining olive oil (without rubbing), and pop it back in for 30 to 40 minutes. Rotate halfway through to evenly puff and crackle the skin for that picture-perfect crunch.
Step 7: Rest, Carve, and Serve
Let your porchetta rest for at least 30 minutes or up to 1 and a half hours to allow juices to redistribute. Then, carefully cut the twine and slice with a serrated knife. Serve alongside the silky, flavorful gravy you create by deglazing the roasting tray with water and whisking in reserved pork fat and flour. That gravy pools beautifully around each serving, adding depth and richness to every bite.
How to Serve Porchetta with Crispy Skin and Fennel-Rosemary Rub Recipe
Garnishes
Keep it simple and let the porchetta shine. A sprinkling of fresh rosemary leaves or a few fennel fronds scattered over the top adds a fresh herbal note. Lemon wedges on the side provide a bright citrus contrast that cuts through the richness perfectly.
Side Dishes
Porchetta pairs wonderfully with rustic sides that complement its robust flavors. Think roasted root vegetables like carrots and parsnips, or creamy mashed potatoes for comforting velvetiness. A crisp green salad with a tangy vinaigrette or sautéed greens like kale or spinach balances the richness of the pork beautifully.
Creative Ways to Present
For a special dinner, slice the porchetta and arrange the pieces overlapping on a wooden board for a rustic, shareable style. You can also cube leftovers for sandwiches or use thin slices in a gourmet pork banh mi with pickled vegetables and fresh herbs. This versatility makes the Porchetta with Crispy Skin and Fennel-Rosemary Rub Recipe a true crowd-pleaser well beyond the first serving.
Make Ahead and Storage
Storing Leftovers
Once cooked, store any leftover porchetta in an airtight container in the refrigerator. It will keep wonderfully for 3 to 4 days, retaining its flavor and tenderness. Reheat gently to preserve the moisture and crispy skin texture.
Freezing
You can freeze cooked porchetta slices wrapped tightly in foil or plastic wrap and placed in a freezer bag. It will keep well for up to 3 months. Thaw overnight in the refrigerator and reheat carefully to bring back that crispy skin magic.
Reheating
Reheating porchetta is best done in an oven preheated to 180°C (350°F). Place slices on a baking sheet and cover lightly with foil to prevent drying. Heat for about 15 to 20 minutes until warmed through, then remove the foil for a few minutes if you want to refresh the crispiness of the skin.
FAQs
Can I use pork loin instead of pork belly for this recipe?
Pork loin is leaner and won’t achieve the same luscious texture or crackling as pork belly, which has the perfect fat-to-meat ratio for this Porchetta with Crispy Skin and Fennel-Rosemary Rub Recipe. For the best results, stick with pork belly with the skin on.
Why do I need to refrigerate the pork uncovered before roasting?
This step helps dry out the skin, which is critical for achieving that signature crackling. Moisture is the enemy of crispiness, so letting the skin air-dry in the fridge creates a beautifully textured finish.
Is the salt only for flavor or does it serve other purposes?
Salt is essential not just for seasoning but also for drawing moisture out of the skin, aiding in crispiness development during roasting. It also helps enhance all the aromatic flavors in the rub that seep into the meat.
How do I make sure the skin doesn’t burn during the high heat roasting?
Keep a close eye during the 30 to 40-minute high heat crackling stage and rotate the pork halfway through cooking. If some spots look too dark too soon, you can tent those areas with foil to prevent burning while the rest crisps up evenly.
Can I add other herbs or spices to the fennel-rosemary rub?
Absolutely! While fennel and rosemary are classic, you could experiment with sage, thyme, or even a touch of crushed juniper berries to give your Porchetta with Crispy Skin and Fennel-Rosemary Rub Recipe your own twist. Just be mindful not to overpower the pork’s natural flavor.
Final Thoughts

Ingredients
Meat and Marinade
- 2.5 kg / 5 lb pork belly with skin on (not scored)
- 3 tbsp finely chopped rosemary leaves (about 1/4 cup leaves, fresh; use 1 tbsp dried if unavailable)
- 6 large garlic cloves, finely grated or crushed
- 2 1/2 tsp cooking salt / kosher salt (halve if using table salt, increase by 50% for salt flakes) – divided
- 2 tbsp olive oil, divided
- 3 tbsp pork belly fat (reserved from roasting for gravy)
Spice Rub
- 2 tbsp fennel seeds
- 2 tsp black peppercorns
- 2 tsp red chili flakes (red pepper flakes)
Gravy
- 1/4 cup plain flour / all-purpose flour
- 2 cups water
- 1/4 tsp freshly ground black pepper
- Salt, if needed (usually not required)
Instructions
- Toast Spices: Preheat a small pan over medium heat without oil. Toast the fennel seeds and black peppercorns, tossing regularly, for 1.5 to 2 minutes until the fennel seeds are lightly browned and fragrant.
- Make Porchetta Rub: Crush the toasted fennel seeds and peppercorns into a coarse powder using a mortar and pestle or spice grinder. Add red chili flakes, rosemary, garlic, and 2 1/2 tsp salt to make a thick, wet paste. Mix thoroughly with a spoon.
- Trim Excess Meat from Pork Belly: Pat the pork skin dry with paper towels. Cut off about 3 cm (2.2 inches) of meat along one long edge, leaving the skin intact. This helps the pork roll neatly and allows the skin to fully enclose the meat. Reserve the trimmed meat for stuffing.
- Score Pork Flesh: Using a sharp knife, score 3 cm (1.2 inch) diamond-shaped cuts into the flesh side about 1 cm (0.4 inch) deep, taking care not to cut through the skin.
- Apply Rub: Using your hands, evenly spread the porchetta rub into the scored flesh, making sure to get the rub deep into the cuts. Also rub the reserved trimmed meat piece with the spice paste.
- Roll and Tie: Place the trimmed piece of pork in the middle of the main pork belly piece. Roll the pork belly tightly to enclose the meat, then tie the roll securely with kitchen twine at 2.5 cm (1 inch) intervals, starting from the center, then both ends, and finally filling in the middle. You should have around 8 evenly spaced ties.
- Dry in Fridge: Place the tied pork belly roll on a rack set over a tray and refrigerate uncovered for 24 to 48 hours. This step allows the rub to infuse and the skin to dry, which is key for good crackling. At minimum, let it rest uncovered for 12 hours.
- Preheat Oven and Prepare Skin: Preheat the oven to 110°C (215°F) with the rack in the middle position. Remove the pork from the fridge and wipe the tray underneath clean. Rub 1 tablespoon of olive oil evenly over the pork skin, then sprinkle and rub in the salt thoroughly. Make sure the salt is evenly distributed, including on the kitchen twine and around the roll. Roll the pork on the salt on the tray to spread the seasoning.
- Slow Roast: Place the pork on a clean rack set over a tray. Roast slowly at 110°C (215°F) for 3 1/2 hours. The pork flesh should become tender but remain intact, and the skin should still be soft at this stage.
- Increase Oven Temperature and Add Oil: Remove the pork from the oven and increase the oven temperature to 240°C (465°F). Transfer the pork still on the rack to a clean tray, reserving the drippings tray for gravy. Drizzle the remaining 1 tablespoon olive oil evenly over the pork skin without rubbing it in. Return the pork to the oven promptly as it is heating up.
- Crisp the Crackling: Roast the pork at 240°C (465°F) for 30 to 40 minutes, rotating the tray halfway through (around 15-20 minutes). The skin should puff up beautifully and become crisp and crackly all over—including the sides and top.
- Rest and Carve: Remove the porchetta from the oven and rest it for at least 30 minutes (up to 1.5 hours) before cutting the twine. Use a serrated knife to slice the porchetta into thick rounds to serve.
- Make the Gravy: Pour all fat from the slow roasting tray into a jug without scraping the tray. Place the tray on the stove over medium heat and add 1/2 cup water to deglaze, stirring to loosen bits stuck to the tray. If needed, use boiling water or heat the tray in the oven to help loosen drippings.
- Prepare Gravy Sauce: Heat 3 tablespoons of the reserved pork fat in a large saucepan over medium-high heat. Add 1/4 cup plain flour and stir continuously for about 1 minute to form a roux. Slowly whisk in the deglazing water and the remaining water (total 2 cups), along with freshly ground black pepper. Simmer the gravy for 2 minutes or until thickened. Adjust salt if necessary.
- Serve: Plate slices of porchetta with the gravy poured over or on the side. Enjoy your flavorful and tender porchetta with crispy crackling!
Notes
- Note 1: Do not score the pork belly skin before cooking because it can cause the flavor rub to fall off and affect the crackling.
- Note 2: Fresh rosemary gives the best flavor, but dried rosemary can be used (reduce quantity accordingly).
- Note 3: Proper dry aging in the fridge for 24 to 48 hours is critical for good crackling texture.
- Note 4: Trimming the meat so the pork rolls neatly helps the crackling skin fully enclose the meat for even cooking and presentation.
- Note 5: Maintain low and slow roasting first to tenderize meat, then finish with very high heat for crisp crackling without drying the meat.
