Fennel-Rubbed Pork Roast

This aromatic fennel-rubbed pork roast is a sophisticated yet simple choice for a healthy Sunday lunch or a midweek feast. By using a lean top sirloin cut and a vibrant crust of crushed fennel and anise seeds, the meat is infused with a fragrant, slightly sweet liquorice flavour that perfectly complements the savoury pork without the need for sugary glazes or heavy sauces.

As a diabetes-friendly main course, this recipe prioritises high-quality protein and bold spices over carbohydrates. The addition of crushed red pepper flakes provides a subtle warmth that elevates the dish further. Serve your roasted pork sliced thinly alongside a generous helping of steamed seasonal greens or a crisp garden salad for a balanced, nutritious meal that feels truly indulgent.

Ingredients for Fennel-Rubbed Pork Roast

  • 1.4kg pork top sirloin roast, tied

  • 1 tablespoon olive oil

  • Kosher salt, freshly ground pepper

  • 2 tablespoons fennel seeds, crushed

  • 1 tablespoon anise seeds, crushed

  • 1 teaspoon crushed red pepper flakes

How to make Fennel-Rubbed Pork Roast

Preheat oven to 204°C. Rub pork with oil; season generously with salt and pepper and rub with fennel seeds, anise seeds, and red pepper flakes, pressing to adhere.

Place pork roast, fat side up, on a rimmed baking sheet and roast until deeply browned and an instant-read thermometer inserted into the centre registers 57°C, 60–70 minutes.

Transfer to a cutting board; let pork rest at least 10 minutes before slicing.

DO AHEAD: Pork can be seasoned 1 day ahead. Cover and chill.
