I was disappointed with this, but maybe I should have cooked the potatoes a bit before adding the lamb, as by the time the potatoes had softened the meat was dry. I will try it again sometime as so many people have made such positive comments it must be worth another go.

Very easy to make and very tasty - a favourite in our house.

Unfortunately I wasted four organic lamb steaks on this recipe. I normally cook my lamb steaks for a couple of hours in a very slow oven - when I saw that they had to be cooked for just 30 mins. I was very dubious - I was right - they were as tough as old boots. However, had I done them as I usually do, I think the meal would have been superb.

Tasty and easy. I added garlic when baking in the oven. Served with a green salad and some feta cheese crumbled ober the top. Yum.

I like this because it's all in one tray and you can bang it in the oven quickly when you come in from work and get onn with other things.

fantastic. and very easy. i steamed the vegetables beforehand a little, and used potatoes, leek and butternut squash instead of sweet potatoe. i would next time add some shallots maybe.

This was really easy to make and even nicer to taste. I cooked the potatoes an extra 10-15 minutes before adding the lamb

Can anyone advise what I could cook with this. I was thinking mash and brocolli, but am worried it would be too dry. Maybe potato gratin? Any advise would be much appreciated as I need to impress with this!

This ones a bit tricky to get right. I think I needed to slice my sweet potato thinner, because it wasn't cooked properly after the 20mins. By the time the sweet potato was ready my meat was a bit dry.

Over all though, this was really tasty,and my boyfriend gave it a thumbs up. I'll try it again but will a few changes to the recipe.

Very nice - might stick a couple of cloves of garlic in next time though. Will certainly be making this again!

Was lovely. Next time, I might put the veg (did sweet potato and carrots) in for an extra 10 mins before I put the lamb on top. Served with spring greens.

didn't have flat enough roasting tray so wasn't properly cooked but if cooked longer, would be delicious - dad loved it!

This is deadly easy to make and great taste. I added more veg with sweet potatoes which went down very well.
