    Lamb breast benefits from long slow cooking due to its high fat content, but when done right, there isn't a nicer tasting cut. Delicious with seasonal vegetables and redcurrant jelly (or mint sauce).

    ✔️ Why should you try it?

    1. Uses a cheaper cut of lamb.
    2. Benefits from long slow cooking.
    3. Delicious with seasonal vegetables and roast potatoes.
    4. Perfect for Easter Sunday.

    🥘 Ingredients

    Rolled lamb breast (about 1.5kg) - lamb breast often comes boned, rolled, and if you're really lucky, ready stuffed too. If your lamb breast isn't pre-stuffed you can use the recipe below.

    Onion & Carrots - placed on the bottom of the slow cooker and acts as a trivet for the lamb.

    Rosemary - my favourite herb with lamb. Fresh is best but you can use dried rosemary if you prefer.

    For the stuffing you will need onion, butter, garlic, herbs, sausagemeat, breadcrumbs and an egg.

    🔪 Instructions

    The recipe card with ingredient quantities and detailed instructions can be found at the bottom of the post

    One: If you're lucky your lamb breast will have come pre boned, stuffed and rolled by your butcher. If it hasn't, fry the chopped onion (for the stuffing) in the butter for 5 minutes then mix up all the stuffing ingredients in a bowl. Unroll the lamb, spread the stuffing onto the flesh, and then roll up again and secure with string. Lamb breast should always be rolled on the short edge to create a larger roll.

    Two: Chop the onion and carrots and place them at the bottom of your slow cooker. Add in the rosemary.

    Three: Place your rolled lamb breast on top of the vegetables, season and cook on low for 6-7 hours.

    Four: Leave to rest for 30 minutes before cutting into thick slices.

    Top Tips

    • Ask your butcher to bone, stuff, and roll your lamb breast for you—it's a real time-saver.
    • Lamb breast benefits from long, slow cooking, so resist the urge to cook it on high.
    • For added colour, transfer the slow-cooked lamb to a roasting tray and roast in a very hot oven for 15 minutes.
    • Place peeled potatoes (halving any large ones) in the slow cooker with onions and carrots for a complete one-pot meal!
    • If you prefer not to stuff your lamb breast, simply sprinkle chopped rosemary and garlic on the unrolled meat, season, and roll it back up.

    🍴 Serving suggestions

    The slow cooker lamb breast is best served with crispy polenta roast potatoes, tenderstem broccoli, cauliflower cheese, cheesy leeks, sweet potato and Yorkshire puddings.

    Cauliflower & broccoli cheese, creamed leeks and spiced red cabbage are other popular side dishes that go really well with lamb.

    Sliced rolled lamb breast.

    🥡 Storage

    Any leftover lamb can be stored in the fridge for up to 3 days. Reheat in the microwave with leftover vegetables and gravy for an easy dinner or lunch.

    ❓ FAQS

    How do you cook lamb so it's tender?

    The key to cooking any tougher fattier cut of lamb (like breast) is to cook it long and slow. That's why the slow cooker is perfect for cooking lamb.

    Can I cook lamb breast in the oven?

    Yes! You can cook rolled lamb breast in a very low oven (150°c) for 3 hours.

      Is no stock or water or any other liquid added to the slowcooker?

        Hi Ruth. No water or stock needed for this recipe. The lamb comes out lovely and tender without additional liquid.

      I only had one carrot to spare as I needed to steam the rest for a side dish so I added some chopped celery as I wanted to use the veggies to make gravy. I did pop it in the oven to brown as I had it on for some veg and it looked a little insipid in my Instapot but it was fabulous and we all loved it. A definite keep. Thanks so much for the recipe and idea of slow roasting in the slow cooker. Inspirational.

      As I am roasting potatoes, would popping it in the oven for 30 mins or so crisp up the skin?
