How To Cook Lamb In Slow Cooker

You’re going to love how simple this slow cooker lamb recipe is to put together and cook, as well as how delicious it is to eat!

Step One – Prepare the slow cooker

  • Preheat the slow cooker to the low heat setting. This gives the meat 8 hours cooking time.

Step Two – Add the ingredients

  • Make incisions in the leg of lamb and push in the sliced garlic. Any leftover garlic slices, just press on top of the lamb.
  • Add the fresh herbs to the bottom of the slow cooker bowl.
  • Rest the half leg of lamb on top.
  • Pour over the beef stock and red wine.
  • Scatter over the salt, pepper and dried oregano.

Step Three – Cook the slow cooker lamb

  • Pop the lid on the slow cooker and leave for 8 hours. After around 7 hours, check how the lamb is doing, if it is cooked through properly, then remove the lamb and rest. If not, continue to cook for longer until it’s done to you liking.

Step Four Make a gravy

  • Lamb is quite a fatty meat, so you need to skim the fat from the top of the cooking liquid using a spoon to avoid a fatty gravy.
  • Once skimmed, pour the cooking liquids through a sieve to remove the herbs and garlic slices. Then pour into a saucepan.
  • Thicken the gravy by adding 2 tsp of cornflour to a small amount of cold water and mixing into a paste. Then add this to the cooking liquid, and bring back to the boil and simmer until it thickens.

Slow Cooker Lamb Recipe Tips & Ideas

Can you put raw lamb in the slow cooker?

Yes, and that’s what makes slow cooking so simple and quick to prepare.

Can you overcook lamb in a slow cooker?

Wondering how long to cook lamb in slow cooker? And yes, you can overcook lamb in the slow cooker. To prevent this happening, it’s best to cook on low temperatures for a long period of time – like around 8 hours.

This gives the lamb meat time to tenderise but shouldn’t cause over cooking or drying out. Just be sure to check it after around 7 hours as all slow cookers cook at different temperatures and speeds.

Do you have to brown lamb before slow cooking?

Well.. I’d say no because I like to just ‘dump and go’ with my slow cooker recipes. Of course there’s those who like to brown the lamb for a more caramelised flavour and swear by it. However, it’s not necessary – just down to personal preference and the amount of time you have to spare.

What cut of lamb is best for slow cooker?

Go for typically tougher joints like whole or half leg of lamb, or lamb shoulder. These are full of connective tissue and fat, which is actually a good thing for slow cooking!

The long, slow cooking on a low temperature causes these to break down and become melt in the mouth tender.

Our favourite is slow cooker half leg of lamb, it fits int the slow cooker bowl and just cooks to perfection!

What herbs go with lamb?

Lamb is a strong tasting meat and can hold it’s own with an abundance of herbs and spices. When we cook this for a traditional roast dinner, we opt for garlic, rosemary, thyme and bay leaves.

When we cook the lamb for an Indian or Mediterranean style dish then I go all out with the spice mixes. For Indian food you can add cumin, chilli powder, turmeric, even curry pastes or powders.

For Mediterranean style dishes I opt for Moroccan style spice blends or harissa paste, lots of garlic and scatter over fresh flat leaf parsley when serving.
