the is a really delicious recipe but i would recommend starting the sweet potatoes in the oven for 10-15minutes before adding the lamb steaks

I cooked this meal for a romantic night in, and wow it was good. Great flavours, simple but effective. Goes great with roasted carrots. Start cooking the potatoes before adding the meat as it does take longer to cook than stated.

Extremely tasty dish - would also recommend putting in the sweet potatoes in for 10-15 mins before adding the lamb.

Very quick, very easy, definitely will thow in some garlic next time. I also didn't have any Rosemary in but Tyme worked just as well. We had it with Brocolli, Carotts and Parsnips... And a cheeky piece of bread to mop up the juices!

It is a nice and easy one, but I added some garlic and salt. And next time would probably add some red wine for flavour.

As others have mentioned, give the Sweet Potatoes 20mins first at 180, then put the meat in. Simple mid week tasty roast.

Made this on a few occasions and you do really need to part boil the tats before adding to the oven. I always prefer sweet tats with lamb then normal so this was perfect! Was surprised that the mustard tasted sooo good with the lamb! This is def one I will be making again and again and I recommend to all!

I used white potatoes, gave the pots and onions five minutes in oven before adding the chops and topped with redcurrant jelly instead of mustard. I also added seasoning. Very tasty.

Really liked this - used new potatoes instead of sweet, halved and parboiled then roasted with the lamb, and double the rosemary - was out of garlic, but think that would have crowned it!
