Weeknight Porchetta

This weeknight porchetta offers a lighter, quicker take on the traditional Italian roast. By using a lean pork tenderloin instead of the customary fatty belly, this diabetes-friendly main course delivers all the aromatic flavours of fennel, rosemary, and garlic without the heavy saturated fat. Wrapping the lean meat in a few slices of bacon ensures the pork remains succulent and juicy during roasting, while the halved garlic bulbs caramelise in the pan to create a mellow, savoury garnish.

A perfect choice for a healthy evening meal, this dish is naturally low in carbohydrates and high in protein. Serve it alongside plenty of steamed green vegetables, such as cavolo nero or tenderstem broccoli, to keep the meal balanced and nutritious. The preparation is simple enough for a Tuesday night, yet the elegant presentation and fragrant herbs make it sophisticated enough for a weekend dinner with friends.

Ingredients for Weeknight Porchetta

  • 4 garlic cloves, finely chopped

  • plus 2 heads, halved crosswise

  • 1 tablespoon coarsely chopped fresh rosemary, plus 4 sprigs

  • 1 tablespoon fennel seeds, coarsely chopped

  • 1 1/2 teaspoons kosher salt

  • 2 tablespoons olive oil, divided

  • Freshly ground black pepper

  • 1 675g pork tenderloin

  • 4 slices bacon

How to make Weeknight Porchetta

Preheat oven to 425°. Toss chopped garlic, chopped rosemary, fennel seeds, salt, and 1 tablespoon oil in a small bowl; season with pepper.

Rub garlic mixture all over tenderloin (if you have time to do this in the morning, great; refrigerate pork until dinner). Scatter rosemary sprigs in a large baking dish and set tenderloin on top. Wrap bacon slices around tenderloin, tucking ends underneath so bacon stays put. Nestle halved heads of garlic around tenderloin and drizzle everything with remaining 1 tablespoon oil.

Roast until an instant-read thermometer inserted into thickest part of tenderloin registers 145° for medium, 40–45 minutes. Transfer to a cutting board and let rest at least 10 minutes before slicing.
