Ingredients Notes & Substitutions
You only need a handful of ingredients to make this slow cooked lamb shoulder with lemony potatoes recipe. Everything you will need is listed below along with any possible substitutions and ingredient notes. The full list of ingredient quantities can be found in the recipe card at the bottom of this post.
- bone-in lamb shoulder – I have tested this recipe each time with a bone in lamb shoulder. A boneless lamb shoulder will cook more quickly, however the bone helps the lamb to retain more flavour. For this recipe we want the lamb to take longer to cook to result in meat that falls apart. I’ve used a 2.3-2.4kg lamb shoulder. If using a smaller lamb shoulder the cook time can vary. I haven’t tested this recipe with a lamb leg roast but I do think it would work well.
- lemon – you will need the juice and zest of one lemon. The lemon zest is used in the rub and the lemon juice is used for the potatoes.
- waxy potatoes – I’ve used carisma potatoes for this recipe but you can use your choice waxy potatoes.
- chicken broth – or chicken stock. You can use homemade chicken stock. I’ve used this stock powder mixed with water.
Lemon & herb rub
- dried herbs – for the rub you will need dried thyme, whole fennel seeds and dried tarragon. You can substitute thyme for dried rosemary.
- garlic powder and onion powder –
- sea salt flakes
- lemon zest
- extra virgin olive oil – I always recommend extra virgin olive as it is much higher in nutrients and less processed than other olive oils and cooking oils.

Let’s Cook Slow Cooked Lamb Shoulder and Lemony Potatoes!
This is one of those recipes that is pretty hands off, just 15 minutes of prep time and then the oven does the rest of the work for you. This lamb recipe is made with minimal effort and minimal dishes, win-win. Follow the instructions below for perfect lamb every time.
Preheat your oven to 220°C/428°F (conventional).
Add the lemon zest, dried thyme, dried tarragon, whole fennel seeds, garlic powder, onion powder, salt and olive oil to a small bowl. Stir to combine and then spoon the rub onto the surface of the lamb shoulder. Use a clean hand to rub the mixture over the whole top surface of the lamb.


Add the potatoes cut into wedges to a large roasting pan. Add the chicken stock, lemon juice and salt and toss to combine. Push the potatoes the sides of the pan and place the lamb into the centre, skin side up.




Cover the roasting pan with a layer of baking paper and then a layer of aluminium foil, sealing the edges. Place the lamb into the oven and turn the heat down to 180°C/356°F. Slow roast for 4 hours and 30 minutes.

After 4 1/2 hours, remove the foil and baking paper from the pan, turn the oven temperature up to 220°C/428°F and roast for another 30 minutes. You want a really hot oven so that the skin and fat renders and goes crispy. After 30 minutes, remove from the oven and rest for 10 minutes.


Pull the meat apart with two forks and serve alongside the lemony potatoes and your choice of sides. Drizzle the juices over the lamb and potatoes for extra flavour. Season with cracked black pepper to taste.


Recipe Notes
If you would like to turn the pan juices into gravy, strain them through a fine mesh sieve into a medium saucepan / pot, place onto the stove and turn to a medium high heat. Use a mug to remove a half cup or so of liquid and add a tablespoon of corn flour to the liquid. Stir straight away to create a slurry. Return the slurry back to the pan and whisk to combine. Continue stirring as the gravy thickens. Once thickened to your liking, turn off the heat.
Storage
Store leftovers in an airtight container in the fridge for up to 3 days.
