When I lived in the UK (over ten years ago!) I used to eat a lot more lamb. And although I do have some low carb lamb recipes on the blog, I really don't have that many – mainly because it can be expensive, or I can't find the cuts that I like.
But when I saw a rack of lamb on sale recently, I jumped at the chance to enjoy it! I prepared it by giving it a simple coating of mayo, Dijon mustard and fresh rosemary. The flavors work perfectly with the lamb!
The trickiest part is knowing how long to cook it for, and that's where a probe thermometer comes in. Lamb is generally served on the pink side, but whether you prefer it rare (140F) or medium rare (145F) is up to you! I'm a rare meat kind of person – plus if you have leftovers I think they're much better when cooked to rare.
How to Cook a Rack of Lamb with Rosemary
Season the lamb with salt and pepper, then combine the mayonnaise, Dijon mustard and finely chopped rosemary together in a bowl.
Spread the mayo mixture over the lamb, and place it on a small baking sheet (this quarter size pan was perfect).
Roast in a preheated oven until cooked to your liking. Rare took about 20 minutes. Let the lamb rest for 10 minutes.
Carve the lamb into separate sections, then serve.
