Roast Lamb Neck Fillet | Season Herbs

Roast lamb neck fillet is considered a low cost cut but it is not to be overlooked as a versatile meat that packs lots of flavour. There are two options for cooking roast lamb neck, either 15 minutes in the oven or a slow roast of up to 2 to 3 hours.

Both methods require searing in a frying pan beforehand to lock in the juices and prepare the meat for roasting. Don’t be afraid to let the lamb be slightly pink in the middle, if that is to your liking! 

Prepare the Fillet

  • Step 1 - Preheat the oven to 180°C or gas mark 4.
  • Step 2 - Make slits in the lamb and press in the sliced garlic and small sprigs of rosemary from 2 large sprigs. Ensure the garlic and rosemary is fully pressed into the meat and season with salt and pepper.
  • Step 3 - In an oven proof dish, lay 4 whole sprigs of rosemary on a large sheet of foil and bring up the edges of foil to encase the lamb while leaving the top open. 

Sear the Roast Lamb Neck Fillet

  • Step 4 - Rub the neck of the lamb with olive oil and sear in a heavy based frying pan. We are looking for a light brown colouring on all sides, cooking for just 5 minutes. 

How long to cook lamb neck fillet in oven

  • Step 5 - Depending on the size of your cut, add your lamb to the prepared oven dish and pour in the wine. Bake for just 15 minutes or until the lamb is cooked through or slightly pink in the middle. Rest for 5 minutes before serving.

Roast potatoes, parsnips and butternut squash

  • Step 6 - Let’s complete the dish. Cut the potatoes into small roasts and parboil for 5 minutes, drain and toss in the oil.
  • Step 7 - Chop the rosemary from the remaining sprig and sprinkle over the potatoes. Add parsnips and butternut squash to the baking tray and cook with the lamb for 45 minutes.
  • Step 8 - Serve the lamb with the potatoes and vegetables, pouring over the excess juices.
