FAQs
I recommend the bone in leg of lamb for fried honey Dijon leg of lamb. Boneless is fine if that is all you can find, but the bone in helps kick up the umami and deepens the flavor of the meat.
For leg of lamb, which is a nice thick and round roast of a cut, you want an internal temp of 145ยฐ for medium rare, 160ยฐ for medium, and 170ยฐ for well done. Personally, I think cooking leg of lamb that hard would be a travesty, but some people just prefer super well done meat.
Might not be my style, but to each their own.
sounds a great recipe, will be trying this for Sunday Lunch tomorrow, one question… did you cook the lamb with the lid up or down ?
For the Big-Easy, I cooked it with the lid off. On a traditional grill / smoker I would have slow smoked w/ lid on. Thanks!
How long did your lamb take to cook, to get to the proper temp?
Hi Simeren, There isn’t an exact time, as each cut is different but try for 15 minutes per pound for your roast. Using a good instant read thermometer is super important to make sure you don’t over cook the meat. Cheers!
Did you find the honey burned when you made this?
Looks so yummy! Pictures look so good.
Turkey!
I just thought of something, Lamb is OK but a brisket would be out of this world, I have got to try this.
The recopies sound awesome, the pictures of look great, if you’re a fat guy on a diet your screwed.
If I had this Big Easy Oil-Less Fryer on Thanksgiving the first thing I would make is a Crรฉole injected turkey. I need this in my life!!!!
The first thing I would make in your Big Easy Oil-less Fryer is fried chicken. I am a fried chicken fanatic!
A turkey of course! Just think of all the things you can make with the leftovers.
Obviously a fried turkey would be in order!
I’ve never been a fan of lamb, but this recipe is making me rethink that decision.
True story Crodelia, it isn’t my favorite either! But I have learned to experiment with things and give them another shot. This recipe was worth it ;D
Oh my friend. I am in love. Lamb is my absolute favorite meat and that roast is cooked to perfection. Seriously. I could easily devour the whole thing.
I love lamb too – it looks incredible!
