Harissa-Crusted Tri-Tip Roast

This harissa-crusted tri-tip roast is a vibrant, spice-led dish that brings an aromatic North African influence to your Sunday table. By creating a homemade harissa paste with toasted caraway, garlic, and cumin, the beef is infused with a deep, smoky heat that perfectly complements the rich flavour of the meat. It is a fantastic way to elevate a lean cut of beef into something truly special.

As a diabetes-friendly main course, this recipe prioritises high-quality protein and heart-healthy fats from olive oil while remaining low in sugar. The use of a wire rack during roasting ensures the heat circulates evenly, resulting in a beautifully tender finish. Serve sliced thinly with a side of roasted Mediterranean vegetables or a crisp green salad for a balanced, nutritious meal.
