This spice-roasted porterhouse steak dish is an excellent choice for anyone seeking a satisfying, diabetes-friendly main course. By using thick-cut steaks and a fragrant coriander-herb rub, you create a deeply savoury crust that perfectly complements the rich, tender meat. Roasting at a high temperature ensures a succulent finish without the need for heavy sauces, keeping the focus on the quality of the beef and the aromatic spices.

Ideal for a weekend dinner or a special occasion, this recipe provides a sophisticated balance of lean fillet and marbled loin.

Ingredients for Spice-Roasted Porterhouse Steaks

  • Two 2-inch-thick porterhouse steaks

  • Olive oil

  • 1 1/2 tablespoons Coriander-Herb Spice Rub

How to make Spice-Roasted Porterhouse Steaks

Place two 2-inch-thick porterhouse steaks on a heavy rimmed baking sheet. Brush both sides with a full-flavoured olive oil, then rub 1 1/2 tablespoons of the Coriander-Herb Spice Rub into each side of each steak.

Preheat the oven to 232°C. Roast steaks until a meat thermometer inserted into the centre registers 52°C for rare, about 25 minutes. Transfer the steaks to a cutting board, cover loosely with foil, and let rest 10 minutes. To serve, cut the 2 whole pieces of meat (known as the loin and the fillet) from each steak, and slice. Give each guest a few slices of the loin and the fillet.
