Succulent, tender roasted rack of lamb can make a very special main course for any springtime celebration, and with a little advance prep, it’s quick to make, too. I use garlic, olive oil, and rosemary to make a delicious Mediterranean-style rub that works perfectly with the lamb and will make your kitchen smell irresistible.

What is Frenched lamb? 

“Frenched” means that the bones of the roast have been trimmed of any meat, fat, and membranes for a cleaner look. You can ask your butcher to do this, or you can watch a tutorial on Fine Cooking and do it yourself, if you’re up to the challenge! 

How long do you cook a rack of lamb?

Cooking times vary somewhat, depending on the exact temperature you’re aiming for, but since lamb racks cook quickly due of their small size, plan on about 20-25 minutes in a 450°F oven to achieve a medium-rare temperature.

What’s the best temperature for lamb?

Many people enjoy lamb the way they enjoy their steak; there’s no need to cook lamb to well done unless that’s the way you prefer it.

Can rack of lamb be cooked on the grill?

Yes, it can. Preheat your grill to 450°F. Start with the lamb fat side down, then flip after 10-15 minutes, and cook another 10 minutes. Be sure to monitor this carefully, however, because lamb has more fat and could catch fire while grilling. As in the recipe, allow the lamb to rest before carving.
