Rich and tender slow cooker lamb ragu perfect for serving with pappardelle or polenta, this dish makes a perfectly cozy family Sunday meal.

Lamb in the slow cooker

The slow cooker and a large piece of lamb are made for each other. Just a minimum of preparation, then give the cooker the time it needs, and the results are always perfect: irresistibly tender and flavorful meat.

Just the way this particular recipe for slow cooker lamb ragu is. The meat is perfectly tender, the gravy is rich and packed with flavor. You will lick the plate clean. Serve this over some pappardelle or soft polenta and you will need nothing more.

And if you like slow-cooked lamb, you could also try the Lamb Casserole, the Lamb Shoulder in the Slow Cooker, or the Slow-Cooked Lamb Shoulder which is cooked in the oven.

  • I prefer the shoulder, but the leg is fine as well, a piece weighing about 1.3/ 3 lbs.
  • If you use boneless meat, about 1 kg/ 2.2 lbs. should be enough.
  • As you can see in the photographs, I had a piece of meat that still had the skin on. That is fine, but if you have a skinless cut that is even better, the dish will have less fat in it. I try to remove as much of the skin as possible before shredding the meat.


  • I had already chopped bacon. If you have a whole piece, chop it roughly.
  • You could leave out the bacon and the dish will still taste very good. However, I like it better with the bacon, it is hearty and imparts the lamb ragu extra flavor.


  • I use homemade lamb stock when I have it. However, when I don’t, I go for chicken or beef stock. Lamb stock is not often available in stores, so chances are that unless you make it yourself, you might have to replace it anyway. When using commercial stock make sure it is low sodium, regular sorts might make the dish too salty.

Vegetables: onion, garlic, carrots, canned tomatoes.

Spices: dried thyme, bay leaves, chili flakes, salt and pepper.

Other ingredients: tomato paste, red wine vinegar.

How to serve slow-cooked lamb ragu?

Serve immediately or reheat before serving.

An extremely popular way of serving lamb ragu is with pappardelle, no idea why… but people seem to like it… Indeed, a tasty combination, but rest assured that any other kind of pasta shape will taste equally delicious.

My favorite combination is ragu with soft basic polenta, I am crazy about polenta in any form, and the way it soaks that gravy is just out of this world. You can also serve the dish with mashed or boiled potatoes, bulgur, or rice.

And sprinkle a bit of freshly grated Parmesan on top if you like.

Make in advance

You can cook the dish in advance, transfer everything to another pot, let cool and refrigerate until ready to serve. Reheat on the stovetop before serving.

Alternatively, you can brown the meat on the stove, make the sauce on the stovetop as well. Let everything cool and keep refrigerated until the next day or when ready to cook in the slow cooker.

What to do with leftovers?

The slow cooker lamb ragu keeps well in the fridge for at least 2-3 days and you can reheat it repeatedly, it gets even better after reheating. You can freeze the leftovers for up to 3 months in an airtight container. Defrost in the fridge and reheat properly before serving.
