This rosemary scented lamb loin with blue cheese, leek and potato gratin is bursting full of flavours and make the perfect dinner night option.


  • 175g medium potatoes
  • 1 clove of garlic
  • 1 bunch of rosemary
  • 150g leek
  • 150g green beans
  • 150g creme fraiche
  • 2 lamb loin
  • 150g baby spinach
  • 200g blue cheese
  • 36g red wine stock
  • 150ml water for the sauce


1Preheat your oven to 200°C. Pop a saucepan of water with 0.5 tsp of salt onto boil for the potatoes. Peel the potatoes and slice into rounds ½cm thick. Trim the root and dark green part from the leek. Halve lengthways then thinly slice widthways. Peel and grate the garlic (or use a garlic press). Trim the green beans and chop in half. Pick the rosemary leaves from their stalks and roughly chop (discard the stalks). Add the potato to the pan and simmer until tender, 10-12 mins.

2Meanwhile, heat a splash of oil in another pan on medium heat. Add the leek, half the rosemary and a pinch of salt. Cook, stirring, until the leeks are soft, 4-5 mins. Add the garlic and cook for a minute. Stir in the creme fraiche and bring to a simmer. Remove from the heat. When the potatoes are cooked, drain, then add to the leeks. Turn carefully to coat. Spoon into an appropriate sized ovenproof dish.

3Sprinkle the blue cheese on top of the gratin and bake in the oven until golden and bubbly 12-15 mins. Meanwhile, heat a splash of oil in a large frying pan over medium high heat. Season the lamb loins with salt and pepper and sprinkle over the remaining rosemary. Brown the meat on all sides, 2 mins and then transfer to a baking tray. Roast on the middle shelf for 9-10 mins. Keep the pan we will use it again later.

4Whilst everything is in the oven, rinse the potato pan pop the red wine stock pot into it with the water (see ingredients for amount) and put onto medium heat. Stir to dissolve the stock pot and then simmer until thickened and glossy, about 10 mins.

5When the lamb is ready, wrap loosely in foil and allow to rest for 5 mins. Meanwhile, heat the frying pan over medium heat (add a splash of oil if necessary). Stir fry the green beans until softened, 4-5 mins. Add a splash of water as they cook. Add the spinach and cook until wilted, 2-3 mins. Season well with salt and pepper and then use a spoon to squeeze out any excess water from the spinach. Get ready to serve!

6Heat your sauce through gently before serving if needed. Arrange the green beans and spinach on your plate. Thinly slice the lamb loins and sit on top of the greens. Serve a generous amount of the gratin alongside and spoon the sauce over the meat and around the plate. Enjoy!
