Before starting to explain the recipe for roast lamb, it is important to know the difference between suckling lamb other types of lamb. Classification of lamb meat is determined by the age of the animal:

  • Suckling lamb has a maximum age of one month and a half.
  • Between 6 and 10 weeks old, the animal is referred to as baby lamb.
  • Spring lamb ranges between 12 weeks and 5 months. These have not yet grazed but have been fed with feed.
  • Mutton refers to animals over one years old.

Lamb meat tends to be more tender than some others and is particularly tasty when roasted in the oven. We recommend asking the butcher to mark it ready for the oven, i.e. cut some lines on the meat, without making any deep lines. This will make the lamb roast easily.


When preparing the lamb, spread it with lard or, if you do not have lard or prefer not to use it, use olive oil instead. The purpose of this step is to, on the one hand, make the meat juicier and, on the other hand, form a kind of crust around the lamb meat.

Next, season the meat and place the lamb in a clay pot or, if you do not have this, a baking tray, along with two glasses of water. You can also add some aromatic herbs like thyme or rosemary, or some chopped garlic, parsley, etc. to add extra depth of flavour to the succulent meat.


With the oven preheated to 150 ° C, pop the pan or tray holding the lamb into the oven and cook for at least 45 minutes on one side. Then, turn it over and cook for a further 45 minutes on the other side, so that it's well browned. If you see that the water has evaporated completely, you should add more to ensure that the steam is present during the roasting process, thus avoiding being left with dry, tough meat. The size of the piece will determine the cooking time, so be aware of this and keep an eye on it.

And... enjoy your roast lamb in oven!
