Grass Fed Beef with Herbs

This herb-crusted roast beef is a celebration of simple, high-quality ingredients. By using grass-fed beef such as sirloin or fillet, you ensure a deeper, more complex flavour that pairs beautifully with the earthy notes of fresh thyme, oregano, and flat-leaf parsley. The slow marination process allows the garlic and herbs to penetrate the meat, while a quick sear in a hot frying pan creates a savoury, caramelised crust that locks in the juices.

As a high-protein main dish, this recipe is as nutritious as it is impressive, making it an excellent choice for a weekend gathering or a muscle-building midweek meal. Serving the sliced beef with a bright yellow and green bean salad provides a refreshing contrast to the richness of the meat. Be sure to let the beef rest thoroughly after roasting to ensure every slice remains tender and succulent.
