Rosemary Beef Fillet

This elegant rosemary beef fillet is a celebratory centrepiece that relies on high-quality ingredients and simple techniques. By searing the meat with fresh rosemary sprigs and garlic, you infuse the beef with deep, woody aromatics and a savoury crust. The lean cut of beef tenderloin ensures the dish remains tender and melt-in-the-mouth, while the roasting process provides a consistently succulent finish that is perfect for a Sunday roast or a special dinner party.

As a diabetes-friendly main course, this protein-rich dish is naturally low in carbohydrates and focus on heart-healthy fats like extra-virgin olive oil. Serving the beef with a sharp Dijon or wholegrain mustard adds plenty of punchy flavour without the need for sugary glazes or heavy sauces. Pair it with steamed seasonal greens and roasted root vegetables for a balanced, nutritious, and thoroughly comforting meal.

Ingredients for Rosemary Beef Fillet

  • 1 (3 1/2-lb) trimmed and tied centre-cut beef tenderloin roast at room temperature

  • 4 teaspoons kosher salt

  • 1 teaspoon black pepper

  • 2 garlic cloves, finely chopped

  • 6 (3- to 4-inch) fresh rosemary sprigs

  • 45ml extra-virgin olive oil

How to make Rosemary Beef Fillet

Put oven rack in middle position and preheat oven to 177°C.

Pat tenderloin dry, then coat all sides with salt, pepper, and garlic. Tuck rosemary sprigs under strings on all sides of roast, leaving a few inches between each.

Heat oil in a flameproof heavy roasting pan over high heat until hot but not smoking, then brown tenderloin on all sides (but not ends), about 10 minutes total.

Transfer pan to oven and roast until thermometer inserted diagonally 2 inches into centre of meat registers 49°C, 25 to 30 minutes. Transfer beef to a cutting board and let stand 15 minutes. (Temperature of meat will rise to about 54°C.) Discard string and rosemary sprigs before slicing.
