One pot slow cooker lamb roast

So about a week ago i posted a recipe on a beef roast done on the slow cooker so i thought, why not also do lamb? lets get started!

1kg leg of lamb (if you see any fat remove it!)
6 large potatoes, chopped into 1/4 or 1/6's
3 red onions quartered
5 large carrots, peeled and roughly chopped into chunks
1 small butternut squah peeled and chopped
2 tsp freshly finely chopped rosemary
1 head of garlic chopped in half
generous pinch of salt and pepper.
200ml lamb stock cube (or whatever you have to hand)

place the lamb in the bottom of the slow cooker and season with salt and pepper.
place the veggies and garlic over and around the lamb then sprinkle over the rosemary
pour in half the stock and cook on low for 6-8 hours or high for 4-6 hours, check to see if the stock needs topping up ever couple of hours or so.
when the lamb is done. remove it to a plate with the vegetables.
the garlic should be very soft. squeeze it into the juices and leftover stock within the slow cooker and blend it, add a little water if it needs to be thinner.
