How to Make Rosemary Garlic Lamb Rump Roast
- Preheat the oven to 400°F (200°C) and position the rack in the center for even heat distribution during roasting, leaving enough space around the roast.
- Prepare herb rub: In a bowl, finely chop fresh rosemary and mince garlic cloves, then stir in olive oil, sea salt, and freshly ground black pepper until a fragrant paste forms.
- Season the lamb: Pat the rump roast dry with paper towels. Generously rub the herb mixture all over, pressing firmly so rosemary and garlic adhere to every inch of the meat.
