Looking for tried and tested roast lamb recipes - parents will only eat well done

[BCSurvivor]

Hosting Easter dinner for the first time.
I'm cooking a leg of lamb, but, being mostly veggie, I've only cooked lamb a handful of times.
My parents and brother will only eat lamb if it's well done.
I like lamb, and out of choice I would have it medium and very slightly pink.
As my family will only eat well done lamb, without a hint of pink, I am a bit concerned about drying out the meat, or it being tough.
Does anyone have any tried and tested recipes for well done lamb that's still moist?

I would do shoulder for the well done lamb lovers.

@Scampuss the leg is currently bought and in the freezer.

this is delicious.

Do it slow cooked. I Think Nigella has a recipe.

Stud with garlic, rosemary and anchovies. Lay it on a bed of sliced onions. Add in a few glugs of red wine. Cover with foil tightly and put in the oven low for 3 hours. It will fall off the bone and will make a good gravy.

@mumonthehill that sounds amazing!

I would slow cook the leg. This website never lets me down.

N B. Some legs of lamb only fit into a very large slow cooker - if you are using one.
