This hearty Slow Cooker Lamb and Lentil Stew never fails to fight the cold weather. We’ve cooked lamb chunks until tender and juicy in a thick, rich gravy, alongside a satisfying helping of silky, protein-packed lentils. Lentils are a great source of protein, meaning they’ll leave you feeling fuller for longer.
We’ve seasoned our gravy with a heavenly combination of rosemary and thyme, to perfectly complement our diced leg of lamb. You’ll want to make sure all visible fat has been removed before you start cooking. Lamb is gorgeous for slow cooking because it can simmer away for hours without losing its juiciness.
The best thing about this dish is that it’s really simple to throw all of the ingredients together into one casserole dish, and you don’t need to worry about it once it’s bubbling away. Just pop your ingredients into the slow cooker, get on with your day and come home to a kitchen that’s filled with the smell of a hearty home-cooked dinner!
You can make this one in your oven, or in an Instant Pot, if you’d prefer.

Is this cooked on the high or low setting on a slowcooker?
SharonMonday 11th December 2023
Hi Liza, our Slow Cooker Lamb and Lentil Stew is cooked on the high setting. Hope you enjoy the recipe!
Laura ESunday 19th November 2023
Hi there, does the slow cooker on low or high please?
Cheryl LloydThursday 8th February 2024
This recipe cooks for 4-5 hours on high 😊
Pauline BaldwinMonday 13th November 2023
Can I use red lentils instead?
SharonFriday 17th November 2023
Hi Pauline, red lentils have a different texture to green lentils. Red lentils will break up and will make the stew much thicker than it should be, whereas green lentils will hold their shape. Hope this helps.
