At first glance, you may be intimidated by the appearance or the price of a rack of lamb. But rest assured that cooking this cut of meat is surprisingly easy, quick, and customizable to your tastes and preferences.

What Is a Rack of Lamb?

A rack of lamb consists of seven or eight ribs, still connected, that come from either side of the spine. Each rack is approximately 1 1/2 to 2 pounds, and is suitable for 2 to 3 servings. Rack of lamb is tender and flavorful, and is bound to be an impressive centerpiece on your table.

If you are trying lamb for the first time you will notice a flavor profile that is notably different than beef. Lamb generally offers well-balanced, robust, and grassy flavor notes with a nice hint of smokiness. When cooked properly, it is also pleasantly tender.

How To Cook Rack of Lamb

Quick-cooking methods such as roasting or grilling are very suitable for this relatively tender cut of lamb. In comparison, other cuts such as lamb shoulder or leg are inherently tougher, and are better suited for slower cooking methods such as braising. For optimal flavor and texture, a rack of lamb is typically served rare or medium-rare, depending on your preference. You will definitely need a meat thermometer to ensure the proper cooking temperature.

Seasoning Rack of Lamb

Additional flavor can be provided by everything from simple salt-and-pepper seasonings to different herb-based marinades, or even dry spice rubs. Some cooks even add breadcrumb coatings for a crispy crust. However, it is important to remember that this cut of lamb is simply tasty all on its own, and your choice of seasonings should enhance and complement the lamb rather than masking and overwhelming it.

To Sear or Not To Sear

Searing the rack of lamb before finishing it in the oven can be a very good technique, particularly if you have chosen a simple seasoning. Searing renders excess fat from the rack, builds in additional flavor, and can also create a nice caramelization of the surface of the meat.

However, if you are using an herbal marinade or spice rub, particularly one that includes breadcrumbs, searing could burn the coating mixture. For this recipe, I have opted not to sear, but instead to start in the oven roasting at a high temperature to brown the exterior of the lamb and render some of the excess fat without burning the marinade.

“The aromas that come from the oven while this rack of lamb is cooking are fantastic! The herb and garlic paste help keep the meat moist but also impart a delicious flavor. My lamb only needed just over 20 minutes in total to be cooked to medium-rare.” —Julia Hartbeck

Trim any excess fat from the lamb and cross-score the fat side by making shallow diagonal cuts, about 1/4 inch deep and about 1 inch apart.

The Spruce Eats / Diana Chistruga
Rub the lamb with salt and pepper on all sides and place it on a rimmed baking sheet.

Place the garlic, olive oil, rosemary, thyme, lemon juice, and Dijon mustard in a small food processor and pulse until it becomes a paste.

Rub the mixture all over the lamb, focusing in particular on pushing the mixture into the scored fat side.

Cover with plastic wrap and store at room temperature for 1 1/2 hours, or up to overnight in the refrigerator. If stored in the refrigerator, be sure to bring it back to room temperature for about 1 hour for proper roasting results. Meanwhile, position a rack in the center of the oven and heat to 450 F.

Remove the plastic, and wrap the exposed frenched bones with foil to prevent excessive browning or burning.

Roast for 10 minutes to brown the fat cap and render any excess fat from the lamb.

The Spruce Eats / Diana Chistruga
Reduce the temperature to 325 F and roast for an additional 10 to 20 minutes, depending on the size of the rack, until a thermometer inserted in the center reads 120 F for rare or 130 F for medium-rare.

Tent the lamb with foil and allow it to rest for 10 minutes before carving between the bones to serve individual chops.

Recipe Tips

Cooking this tender cut of lamb initially on high heat helps with browning the exposed surface of the lamb while rendering any excess fat. The temperature is then lowered to ensure proper cooking throughout the center of the lamb.
To make sure that the lamb is cooked to your desired doneness level, there are many variables to consider regarding the size, shape, and fat content, so using an accurate meat thermometer is the key. Keep in mind that the temperature will continue to rise by 5 to 10 degrees during the resting period.
Each rack of lamb serves 2-3 people. The recipe can easily be doubled to serve 4-6.

Recipe Variations

While I definitely enjoy the flavors of a traditional roasted rack of lamb, I also enjoy applying some Persian culinary techniques. I first marinate the lamb in a combination of bloomed saffron, grated onions, yogurt, and lemon juice. In this case, the rack can be either grilled or oven-roasted. Alternatively, a simple but impactful rub of sumac, lemon zest, and garlic paste will hit all the familiar Persian notes.

What is Frenching?

When selecting a rack of lamb you will likely encounter the term “frenching”. This is the process of removing the fat and some of the meat from the tips of the ribs to create a classic, sophisticated presentation. You may find a rack of lamb already frenched at the meat department of your supermarket, or you may simply request this service from your butcher. Alternatively, if you find yourself looking for a bit of adventure and have some time on your hands, you can certainly tackle this task on your own.
