Porchetta

This classic Italian porchetta is a show-stopping centrepiece that brings the authentic flavours of a Roman rotisserie into your home kitchen. By wrapping a lean pork loin inside a succulent, herb-rubbed pork belly, you create a roast that is beautifully balanced in texture. The aromatic blend of toasted fennel seeds, fresh rosemary, and garlic permeates the meat, while the traditional air-drying method ensures the crackling achieves a perfect, golden crunch every time.

As a diabetes-friendly option, this dish focuses on high-quality protein and fragrant botanicals rather than sugary glazes or heavy starches. It is an excellent choice for a weekend gathering or a festive celebration, offering a sophisticated alternative to a standard roast. Serve thin slices alongside a vibrant green salad or seasonal roasted vegetables for a nutritious and deeply satisfying savoury meal.

Ingredients for Porchetta

  • 1 5-2.7kg piece fresh pork belly, skin on

  • 1 (trimmed) 2-1.4kg boneless, centre-cut pork loin

  • 3 tablespoons fennel seeds

  • 2 tablespoons crushed red pepper flakes

  • 2 tablespoons minced fresh sage

  • 1 tablespoon minced fresh rosemary

  • 3 garlic cloves, minced

  • Kosher salt

  • 1/2 orange, seeded, thinly sliced

How to make Porchetta

Put belly skin side down; arrange loin in centre. Roll belly around loin so the short ends of the belly meet. If any of the belly or loin overhangs, trim meat. Unroll; set loin aside.

Toast fennel seeds and red pepper flakes in a small skillet over medium heat until fragrant, about 1 minute. Tip spices into a bowl; let cool. Finely grind spices in a spice mill and transfer to a small bowl, along with the sage, rosemary, and garlic; set fennel mixture aside.

Assemble porchetta according to steps 1-5.

Refrigerate roast, uncovered, for 1-2 days to allow skin to air-dry; pat occasionally with paper towels.

Let porchetta sit at room temperature for 2 hours. Preheat oven to 260°C. Season porchetta with salt. Roast on rack in baking sheet, turning once, for 40 minutes. Reduce heat to 149°C and continue roasting, rotating the pan and turning porchetta occasionally, until an instant-read thermometer inserted into centre of meat registers 63°C, 1 1/2-2 hours more. If skin is not yet deep brown and crisp, increase heat to 260°C and roast for 10 minutes more. Let rest for 30 minutes. Using a serrated knife, slice into 1/2" rounds.

  1. Set belly skin side down. Using a knife, score the belly flesh in a checkerboard pattern 1/3" deep so roast will cook evenly.

  2. Flip belly skin side up. Using a paring knife, poke dozens of 1/8"-deep holes through skin all over belly. Don't be gentle! Keep poking.

  3. Using the jagged edge of a meat mallet, pound skin all over for 3 minutes to tenderize, which will help make skin crispy when roasted.

  4. Turn belly and generously salt both it and loin; rub both with fennel mixture. Arrange loin down middle of belly. Top with orange slices.

  5. Roll belly around loin; tie crosswise with kitchen twine at 1/2" intervals. Trim twine. Transfer roast to a wire rack set in a rimmed baking sheet.
