This succulent lamb recipe feels really special and is full of flavour. Try it as your go to Easter recipe this year and your guests will be more than impressed. This lamb recipe uses a balsamic glaze to really ramp up a sweet and sharp flavour in the meat.



  1. Place the racks of lamb in a large non-metallic dish. Mix together 8tbsp olive oil, the lemon juice, half the oregano, garlic and seasoning and pour over the lamb. Leave to marinate in the fridge for at least 2 hours or up to 24 hours if possible. To make the balsamic glaze, mix together the balsamic vinegar, clear honey, mint, salt and freshly milled black pepper in a small bowl, then set aside.
  2. Preheat the oven to 200 C, 180 C fan, 400 F, gas 6. Brown the racks of lamb in a little olive oil until browned on the outside, then place on a large baking tray and roast for 20 minutes per 450g (1lb) for pink lamb, 25 minutes for well done.
  3. Arrange the potato, sweet potato, courgette and onion slices in a large roasting dish. Drizzle over the remaining olive oil and season well. Bake in the oven for 30 to 40 minutes or until golden.
  4. Five minutes before the end of cooking, brush the lamb racks with the balsamic glaze, then cook for another 5 minutes or until cooked but slightly pink in the middle. Pour the rest of the balsamic glaze into a small bowl and serve with the lamb. Carve the lamb into cutlets and serve with the sweet potato gratin.

Top Tip for making Balsamic Glazed Rack of Lamb with Sweet Potato Gratin

Use the slicing blade on your food processor to cut the vegetables in a matter of minutes. If you have a cook’s blowtorch, use it to brown any bits of the lamb fat that need it. You can marinate the lamb up to 24 hours ahead and the glaze can be made the day before too.
