I had a small lamb roast, just under 2 lbs and was looking for something to do with it. I came upon this recipe, and I am so glad I did. I did not use as many potatoes or onions, as it's just me right now, and used only about half the broth. It roasted rather faster than indicated, but that might be a function of my using a countertop oven right now. The roast was perfectly done, and I am glad that I checked it early! Potatoes and onions were very tasty, also.
Delicious! I cooked for the extra 40 minutes so only change I made was to give the vegies a mix at that stage and add a touch extra stock. I didn't do it but you could also throw in a few handfuls of frozen vegies at the same stage for a complete meal in one pan.
