Classic Porchetta Recipe

Prepare and brine (optional dry cure)

Pat the pork belly and shoulder dry with paper towels. Score the skin of the belly in parallel 1/2-inch lines through the skin but not through the fat (if not already scored). Mix 1 1/2 tablespoons kosher salt, black pepper, fennel pollen (or ground fennel), chopped rosemary, chopped sage, minced garlic, lemon zest, and 1 tablespoon olive oil into a paste. Rub two-thirds of this herb-garlic paste into the meat side of the butterflied belly and onto the pork shoulder pieces. Reserve the remaining paste to use on the exterior later. If you have time, tightly wrap the seasoned meat in plastic and refrigerate overnight to develop flavor and help dry the skin for crisping; otherwise continue immediately.

Roll and truss

Lay the seasoned pork belly skin-side down. Place the pork shoulder pieces evenly along the belly, leaving a 1-inch margin at one long edge. Starting from the edge with the shoulder, roll the belly tightly into a log so the shoulder is enclosed inside the belly roll and the skin becomes the exterior. Tie the roll tightly at 1- to 1 1/2-inch intervals with butcher's twine to hold shape and ensure even cooking. Tuck any loose ends under the roll.

Dry and season exterior

If the pork was refrigerated overnight, remove it and let it come toward refrigerator temperature (30–60 minutes). Pat the outside skin dry again. Rub the remaining herb paste (if any) onto the seam and ends (not on the skin). Rub 1 tablespoon olive oil over the skin and then rub 1 tablespoon kosher salt evenly over the skin surface to help draw moisture out and encourage crackling.

Roast low and slow

Preheat oven to 275°F (135°C). Place the porchetta seam-side down on a rack in a roasting pan. Add 1 cup white wine or 1 cup water to the pan (this prevents drippings from burning and yields flavorful pan juices). Roast at 275°F until the internal temperature reaches 145°F (63°C) in the center — about 2 to 2 1/2 hours for a ~3 lb roll. Baste pan juices over the meat occasionally. If the skin begins to bubble prematurely, you may tent lightly with foil until final crisping.

Rest before crisping

Remove the porchetta from the oven when internal temp is 145°F. Increase oven temperature to 475°F (245°C). Loosely tent the porchetta with foil and let rest 15–20 minutes; this helps redistribute juices and firms the roll for slicing. Carefully remove the foil and pat the skin dry again with paper towel if there is any moisture on the surface.

Final high-heat crisp

Brush the skin with 1 tablespoon oil and sprinkle the additional tablespoon of kosher salt evenly over the skin. Transfer the porchetta back to the oven (uncovered) at 475°F (245°C) on the roasting rack and roast until the skin is blistered, deep golden and crackling — about 20–30 minutes. Watch closely to avoid burning; rotate pan if necessary for even browning. For very stubborn leathery skin, you can briefly use the oven broiler (keep door ajar and watch carefully) for 1–3 minutes to finish the crackle.

Final rest

Remove porchetta from oven and let rest 10 minutes before slicing — this preserves juices and prevents tearing the crackling. Remove butcher's twine and slice on a sharp knife into 1/3 lb (approx. single-sandwich) portions or thinner slices for multiple servings. Expect a mix of juicy meat and crisp crackling in each slice.

Prepare bread and garnish

If desired, lightly toast the pain au lait rolls cut-side down in a skillet or oven until just golden. Spread each roll with butter or aioli. Layer 1/3 lb hand-sliced porchetta per sandwich (about 1 to 1 1/2 thick slices depending on roll size). Add a handful of arugula or baby greens and a spoonful of pickled red onions or pickles for brightness and balance.

Serve

Serve sandwiches immediately while the porchetta crackling is crisp. Leftover porchetta keeps 3–4 days refrigerated; reheat gently in a low oven to preserve crispness or slice cold for salads or charcuterie.
