Overnight Slow Cooked Lamb roast

I could bang in lamb roasts until the cows come home! Here’s my classic recipe for lamb shoulder, rubbed with a coffee based seasoning, served with red wine sauce/jus, silky smooth mashed spuds, carrots, celery, onions and fresh rosemary. I reckon you will get around this like I do!

One thing I want to emphasize about cooking roast lamb DO NOT go off time to weight ratio like a lot of old school recipes tell you too. That is a VERY rough guide as every piece of lamb is different and take different lengths of cooking to achieve the same result. Conversely, always determine fines of roast lamb by the feel when you push a thin skewer through the thickest parts of the meat. When it feels like you have almost no resistance or you are pushing the skewer through butter you are done.

Overnight Slow Cooked Lamb roast

Ingredients

    blank

    • 5 potatoes

    • 100g chopped unsalted butter

    • 50ml cream or milk

    • salt and pepper to taste

    • 1 tbsp garlic granules

    • 1/2 tbsp smoked paprika

    blank

    • 2-2.5kg/4.41-5.51lb lamb shoulder

    • Backyard BBQ coffee seasoning

    • 2 sprigs fresh rosemary

    • 5 garlic cloves crushed

    • 2 large carrots thickly sliced

    • 2-3 large onions peeled and quartered

    • 4 tbsp tomato paste

    • 1-200ml red wine

    • 2-300ml beef stock

    • 2-3 spoons beef tallow (see my previous vids)

    blank

    • liquid left from lamb cook

    • a splash of red wine on hand

    • 100ml of corn starch slurry

    • cracked pepper to taste

    Directions

      blank

      1. Peel spuds and place in a pot and cover with water. Pinch of salt

      2. Boil until you can easily push a fork through them, drain water and back onto low heat to remove excess water.

      3. Mash them until smooth or pass through a ricer, then add remaining ingredients whilst in the pot on low heat until fully combined. Cover and reheat as required

      1. Preheat your oven or smoker to 120C/250F. Whilst that’s happening, trim off any hard fat on the shoulder. No need to remove it all

      2. Apply a coat of Siracha sauce to act as a binder, then season with Backyard BBQ

      3. Either start cooking late the night before serving, or very early on the morning of. Allow yourself approx 8 hours of cooking time.

      4. Cook lamb until bark has started to form, meat has darkened and should becoming red if smoking. This typically takes 4-6 hours and internal temp is approx 70C/160F

      5. As the lamb approaches this point start the veg

      6. In a large crock pot/casserole dish, bring up to heat on med/high. Once it starts to lightly smoke add beef tallow and cook of onion and carrot. Once they develop colour add remaining veggies and do the same. Then create a space in the middle of the pot and cook the tomato paste for a minute until it gives off a strong tomatoey smell. Mix all together

      7. Add your red wine and this will deglaze the pot too. Then bang in the beef stock. Lastly tip in the lamb shoulder on top, cover tightly with foil or the lid and in the oven at 120C/250F. You will cook the lamb until it “probes like butter”. Allow approx 2-3 hours from this point

      8. Remove lamb and bang into your serving dish, back in the oven turned off to rest and move onto gravy/sauce/jus. Once ready to serve lamb, either slice it or pull apart with your chicken scratchers. As lamb shoulder has large bones I find using my hands easier and rip the meat off.

      1. Strain veg from lamb juice into a pot on medium heat, so it’s at a high simmer

      2. Slowly add slurry until it starts to thicken. Then taste. I like to bang in a bit of pepper and if it’s to thick I adjust with red wine and simmer for another 5 mins or so

      blank

      1. Add mash into a dinner bowl, some of the veg, pulled lamb, then top off with the red wine jus/gravy you just made.
