Personally I don’t think it makes a difference because we’re roasting the leg uncovered, so it does get a chance to get browned and crispy. It will also change roasting time a little bit.

That will take a while at 350 but sure you are welcome to try.

I am going to try at 350F (180C) and use a thermometer to aim for a medium rare doneness.

You should not cover this lamb roast because it will come out over cooked and not roasted. To avoid mess in the oven use a Dutch oven or roasting pan with high walls. No mess.

Not covering it makes a great mess in oven. I made this for my gf and she asked me to cover 3 times I said. It’s not what it says…
It turned out good but…damm I looked like an idiot.

Hi Diane. The times per pound are pretty accurate but again all ovens vary, even brand new ones. I have 2 brand new ovens in the studio and in the house kitchen and they do bake differently. So it’s best to undercook the roast a bit and check with a knife for doneness. You are on the right track of thought. Good luck!

Sure!
