This is my favorite preparation for rack of lamb that’s circulating all over the internet in one form or another. In my adaptation, you cook baby potatoes until creamy and crispy underneath the lamb. The potatoes absorb some of the pan drippings from the lamb, along with the essence of thyme, rosemary, and lemon. It’s a simple recipe that’s big on flavor, that anybody can make.
I just love any cut of lamb, but particularly rack of lamb. It’s intensely savory and has just the right amount of fat for roasting at high heat. To get the potatoes just right, you start by par-boiling them in boiling water. I’ll show you how to get the perfect texture on those so you have a complete meal in under 30 minutes!
So what’s involved?
How to Prepare the Potatoes for Roasting
To start, you set the lamb on the counter to come to room temperature for about 30 minutes. This just helps the lamb cook evenly later. As the oven preheats, drop the golden potatoes whole into a pot of boiling water. Once they are tender, take a spatula and just smash down a bit to give more surface area for roasting.
Seasoning the Rack of Lamb
Season the rack of lamb with salt and pepper and sear on all sides. Do this step in an oven safe skillet, like this cast iron pan. Then just rub dijon mustard all over the meat. This add complexity of flavor (tangy and spicy) to contrast the savory lamb underneath. Now, dip it in the breadcrumb mixture – breadcrumbs, olive oil, garlic, rosemary, and thyme. I like to wrap a bit of tinfoil around the bone tips to prevent burning.
Remember that skillet from searing the lamb? Place the potatoes on the bottom of that same pan (yep, it’s a one pan kind of meal). Season with salt and red chili flakes. You could also add extra rosemary and thyme sprigs to the skillet to infuse the potatoes with a slice of lemon. Now rest the lamb right on top of the potatoes. Into the oven it goes for 14 minutes for medium rare.
Imagine how those lamb drippings are going to season those potatoes. You can’t let something as flavorful as a rack of lamb go to waste…
Tip: When you remove the lamb, allow it to rest (tented under foil) for about 5 minutes so the juices have time to go back to the center of the meat. Turn the potatoes over. They will be nice and golden on the bottom.
I hope you love this recipe as much as my family does and make it over and over again.
