Porchetta Recipe Pork Belly: Herb-Crusted Roast With Crackling Skin

There’s nothing like the aroma of herb-crusted porchetta roasting in the oven, filling the kitchen with the scents of my grandmother’s Sicilian kitchen. This pork belly version delivers the same traditional flavors with a simpler approach for home cooks.

The secret lies in the herb rub—a fragrant blend of rosemary, garlic, and fennel that penetrates the meat as it slow-roasts. I’ve perfected this method over years of Sunday family dinners, ensuring tender meat with crackling skin every time.

You’ll achieve restaurant-quality results with basic ingredients and careful attention to temperature. The pork belly transforms into a golden-brown masterpiece, with herbs forming a delicious crust that’s impossible to resist.

Serve it as the centerpiece of your next gathering, just as we did at family feasts in Sicily. This dish brings tradition to your table with every bite.

Ingredients for Porchetta Recipe Pork Belly

Pork belly, fresh herbs, and a few pantry staples create this show-stopping Sicilian classic.

The pork belly is non-negotiable here—skin-on and unrolled. I get mine from Whole Foods or a good butcher; their meat counter staff can score the skin for you (worth the extra minute). Look for a piece with even fat marbling and thick skin—this is what gives you that iconic crackle. The rosemary and fennel should be fresh and aromatic; if they smell like nothing, they’ll taste like nothing.

No fresh rosemary? Dried at half the amount, but fresh really makes the difference. Fennel seeds can be swapped for anise seeds in a pinch, though the flavor shifts slightly. For the wine, any dry white works—Sauvignon Blanc or Pinot Grigio are my go-tos. If avoiding alcohol, use apple cider vinegar mixed with water (half and half). The garlic can be eyeballed, but don’t skimp on the salt.

The rub can be made a day ahead and stored in the fridge. The pork belly itself should be roasted fresh but keeps beautifully as leftovers—4-5 days in the fridge, or freeze for up to 3 months. Reheat slices in a pan to recrispen the skin (microwave is a sad choice here).

Step-by-Step Instructions for Herb-Crusted Roast With Crackling Skin

This method delivers crispy skin and aromatic herbs in every bite.

Step 1: Create the Herb Rub and Score the Skin

In a small bowl, combine the 0.25 cup Fresh Rosemary (finely chopped), 8 cloves Garlic Cloves (minced to a paste), 2 tbsp Fennel Seeds (lightly crushed), 2 tbsp Kosher Salt, 1 tbsp Black Pepper, 1 tbsp Dried Sage (rubbed between palms), 1 tsp Red Pepper Flakes, 0.25 cup Extra-Virgin Olive Oil, and 1 tbsp Lemon Zest. Stir until it forms a thick, fragrant paste.

Pat the 4 lb Pork Belly dry with paper towels, focusing on the skin side. Using a sharp knife, score the skin in a diamond pattern, cutting just through the skin and fat cap but not into the meat. This scoring ensures the fat renders properly and the skin crisps evenly.

Step 2: Season and Roll the Pork Belly

Lay the pork belly skin-side down on a clean surface. Rub the herb paste all over the meat, pressing it into every crevice. Be generous—the paste should coat the entire surface evenly. This layer will infuse the meat with incredible flavor as it roasts.

Carefully roll the pork belly into a tight log, with the skin on the outside. Tie the roll with kitchen twine at 1-inch intervals to hold its shape. A tight roll ensures even cooking and keeps the filling in place. The twine also helps the skin crisp uniformly.

Step 3: Roast at High Heat for Crackling Skin

Preheat your oven to 450°F. Place the tied pork belly on a wire rack set over a rimmed baking sheet. Roast for 45 minutes until the skin begins to puff and turn golden brown. The high heat is crucial for rendering the fat and creating that signature crackling texture.

After 45 minutes, reduce the oven temperature to 325°F and pour the 0.5 cup White Wine into the baking sheet below the rack. The wine will create steam, keeping the meat moist while the skin continues to crisp. Roast for another 1.5 to 2 hours.

Step 4: Rest and Crisp the Skin Further

Remove the pork belly from the oven and transfer it to a cutting board. Tent it loosely with foil and let it rest for 20 minutes. This resting period allows the juices to redistribute, ensuring the meat stays moist and tender when sliced.

For extra crispiness, place the pork belly back under the broiler for 2-3 minutes just before serving. Watch it closely—it can go from perfectly crisp to burnt in seconds. The skin should be shatteringly crisp, while the inside remains juicy and packed with herb flavor.

Step 5: Slice and Serve with Pan Juices

Remove the twine and slice the pork belly into ½-inch thick rounds. Use a sharp knife and cut cleanly through the skin to maintain its crisp texture. The slices should reveal the beautiful herb layer spiraled through the center.

Drizzle any accumulated pan juices over the sliced pork belly before serving. The juices will add an extra burst of flavor and moisture. Serve warm with your favorite sides, and enjoy the perfect balance of crispy skin and aromatic, tender meat.

Make-Ahead Tips for Leftovers

Herb Paste Prep

I always make the herb rub a day ahead—it lets the flavors meld. Combine all the herbs, garlic, and olive oil in a bowl, then refrigerate for up to 24 hours. The oil will absorb the aromatics beautifully. 🌿

Dry Brine Overnight

Rub the pork belly with the herb paste and salt, then let it sit uncovered in the fridge for 12-24 hours. This step draws out moisture for extra-crispy skin while the flavors penetrate deep into the meat.

Roll and Tie

Roll and tie the pork belly the morning of cooking, then refrigerate until ready to roast. This keeps the shape tight and prevents the roll from unraveling. I use unwaxed kitchen twine for the best hold.

Partial Roasting

You can roast the pork belly at 325°F for 1 hour ahead of time, then finish later. Let it cool before refrigerating, then return to the oven to complete cooking and crisp the skin. ⏰

Pan Juice Storage

Strain and save the pan juices after roasting. They keep in the fridge for 3 days or freeze for up to 1 month. Reheat gently and drizzle over slices when serving for a flavor boost.

Re-Crisping Skin

For leftovers, place slices on a wire rack in a 400°F oven for 5-10 minutes to revive the crackling. Avoid the microwave—it’ll soften that perfect skin you worked so hard to achieve.
