Recipe: Slow-roast lamb roulade

Ingredients

  • 1.5kg Deboned lamb shoulder
  • 2 tsp Salt
  • 1.5 tsp Black pepper
  • 2 tsp Olive oil
  • 20g Unsalted butter
  • 2 Shallots, finely diced
  • 3 Garlic cloves, minced
  • 300g Mushrooms
  • 100g Baby spinach, chopped
  • 20g Hazelnuts
  • 20g Pistachios, roughly chopped
  • 1.5 tbsp Parsley, finely chopped
  • 1.5 tsp Rosemary, finely chopped
  • 1 tbsp Lemon zest

Method:

  1. Preheat oven to 180°C. Roast the hazelnuts for 8 minutes. Cool, then roughly chop.
  2. Blitz the mushrooms in a food processor, scraping down the sides as needed, until the mushrooms are chopped into little 3mm pieces.
  3. Melt the butter in a non-stick pan over high heat. Add shallots, garlic and mushrooms. Cook, stirring regularly, for 5 minutes or until the liquid that comes out of the mushrooms mostly evaporates. Add the baby spinach and cook until wilted.
  4. Transfer the filling into a bowl. Cool for 20 minutes then stir in remaining ingredients.
  5. Pile the stuffing on a piece of cling wrap. Use your hands to roughly shape it into a 35cm long log. Tightly roll up with cling wrap. Place in the freezer for 3 hours (up to 3 days) until it is firm.
  6. Place the lamb shoulder fat-side down. Cover with plastic wrap or baking paper. Then use a rolling pin or meat mallet to pound the meat into a 40 x 22cm rectangle. Aim for even thickness ~1.75cm. Trim and patch as needed to make your rectangle.
  7. Sprinkle the surface of the lamb with half the salt and pepper. Unwrap the frozen stuffing log then roll it up tightly, finishing with the seam side down.
  8. Secure with kitchen twine tied every 2cm.
  9. Preheat the oven to 220°C.
  10. Rub the lamb roll all over with the olive oil, then sprinkle with the remaining salt and pepper.
  11. Serve with buttery baby potatoes, gravy made by thickening the pan juices, and a glass of the Diemersfontein Cabernet Sauvignon.
