A Timeless Easter Tradition: Lamb has long been associated with spring celebrations, symbolizing renewal and new beginnings. Serving a succulent rack of lamb for Easter brings a touch of classic elegance to your holiday feast.
A Delicious Alternative to Ham: While ham is a popular Easter choice, lamb offers a sophisticated and flavorful alternative that stands out. Its tender texture and rich taste provide a delightful change of pace that will be appreciated by all.
Inspired by Culinary Legends: The foundational marinade for this lamb is adapted from none other than Julia Child, ensuring a depth of flavor and culinary excellence that speaks for itself. Her timeless techniques guarantee a perfectly seasoned and tender roast every time.
Elevated with Fresh Parsley Pesto: The homemade parsley pesto is a game-changer. It’s incredibly easy to whip up and adds a bright, fresh, and gourmet touch that elevates the entire dish. While classic mint jelly has its place and is a nod to tradition (as my parents preferred), this vibrant pesto offers a modern, sophisticated twist that truly enhances the lamb’s natural richness.

My inspiration struck when I found beautiful New Zealand rack of lamb at a great price. It was destined to be our Easter main course. The idea of pairing it with a simple parsley pesto immediately made it feel special, promising an elegant meal without demanding hours in the kitchen. Even my discerning husband, Bill, who can be quite particular about new flavors, was intrigued – though a slight hint of skepticism about the pesto pairing was detectable. Thankfully, the results spoke for themselves, and the pesto earned its rightful place!

Key Ingredients for Your Herb Crusted Rack of Lamb

Crafting the perfect herb crust and vibrant pesto requires just a few quality ingredients. Here’s a closer look at what you’ll need:

Kitchen Staples: You’ll start with everyday essentials like garlic cloves, kosher salt, freshly ground black pepper, and dried oregano. These form the aromatic backbone of the herb crust, providing foundational savory notes that complement lamb beautifully.
Fresh Rosemary: The star herb for the crust! Use only the fresh leaves, finely chopped. Fresh rosemary’s pungent, piney, and slightly lemony notes are a classic pairing with lamb, enhancing its rich flavor without overpowering it. While dried herbs are convenient, fresh rosemary truly makes a difference here.
Rack of Lamb: Aim for a rack weighing about 2 pounds, preferably with the bones “frenched.” Frenching, where the meat and fat are trimmed from the ends of the rib bones, not only gives the rack an elegant, professional appearance but also allows for more even cooking around the bones. If your butcher hasn’t done this, don’t worry – it’s a simple process you can do at home (see our FAQ for instructions). Look for “spring lamb” in May and June for the most tender and sweetest meat.

For the Bright Parsley Pesto:

Fresh Parsley: Two cups of vibrant fresh parsley leaves are essential for a bright, herbaceous pesto. Flat-leaf parsley (Italian parsley) is generally preferred for its stronger flavor and more tender leaves compared to curly parsley.
Pecorino Romano Cheese: This hard, salty Italian cheese made from sheep’s milk adds a sharp, tangy, and savory depth to the pesto, complementing the lamb perfectly. If unavailable, Parmesan can be a substitute, but Pecorino Romano offers a distinct flavor profile.
Garlic Clove: Just one clove, finely chopped, provides a gentle aromatic kick to the pesto, balancing the freshness of the parsley and richness of the cheese.
Extra Virgin Olive Oil: A high-quality extra virgin olive oil is crucial for the pesto’s texture and flavor. It emulsifies with the other ingredients, creating a smooth, rich sauce.
Freshly Ground Black Pepper: To taste, adding a subtle warmth and spice that rounds out the pesto’s profile.

Expert Tips for a Perfectly Roasted Rack of Lamb

Achieving a perfectly cooked, juicy rack of lamb is easier than you think with these expert tips:

PRO-Tip: Marinate Ahead for Maximum Flavor: Apply the herb rub to your rack of lamb the day before you plan to roast it. This extended marination time allows the garlic, rosemary, and oregano flavors to deeply penetrate the meat, resulting in a more tender and intensely flavorful roast. Six hours is good, but overnight is even better.
Choose Tender Spring Lamb: While lamb is available year-round, cooking it in the spring when young, tender cuts are more readily available ensures the most succulent and mild-flavored meat. Spring lamb is typically 3-5 months old and known for its delicate taste.
PRO-Tip: Bring to Room Temperature: Before roasting, let your rack of lamb sit at room temperature for about 30 minutes. This crucial step helps the meat cook more evenly from edge to center, preventing a tough, overcooked exterior and a raw interior.
Invest in a Meat Thermometer: Good lamb is a significant investment, and you absolutely do not want to overcook it. A reliable meat thermometer is your best friend for ensuring your lamb is cooked to your preferred doneness, whether that’s a perfect medium-rare or medium. It takes the guesswork out of roasting.
Roast on a Rack: Always roast your lamb on a wire rack set inside a roasting pan. This allows hot air to circulate freely around all sides of the rack, promoting even cooking and creating a beautifully crisp herb crust. It also prevents the bottom of the lamb from steaming in its own juices.

How to Cook a Flawless Herb Crusted Rack of Lamb

While grilling a rack of lamb can be absolutely scrumptious, I find roasting it in the oven to be the most reliable method for achieving that perfect, tender interior and wonderfully aromatic herb crust. Rosemary, a timeless partner for lamb, plays a starring role in both this recipe and my favorite grilled lamb chop recipe. The secret to a truly delicious oven-roasted rack of lamb lies in a well-balanced, flavorful marinade.

Prepare the Herb Crust: Begin by combining fresh rosemary, chopped garlic, kosher salt, and freshly ground black pepper in a food processor. Process until minced, then slowly drizzle in extra virgin olive oil until a thick, fragrant paste forms. This paste is your herb crust.
PRO-Tip: The Marinade Magic: Generously smear this aromatic herb paste all over the surface of your rack of lamb. Like beef, lamb benefits immensely from marinating, anywhere from 6 hours to overnight in the refrigerator. This allows the robust flavors of the herbs and garlic to deeply infuse the meat, contributing to both taste and tenderness.
Bring to Room Temperature: Before roasting, remove the marinated lamb from the refrigerator about 30 minutes in advance. Allowing it to come to room temperature ensures more even cooking.
Preheat Your Oven: Preheat your oven to a high temperature, typically 450°F (232°C). This initial high heat helps to create a beautiful sear and crisp crust on the lamb.
Roasting Time: Place the rack of lamb on a wire rack in a roasting pan. Roast for approximately 25 minutes for a perfect medium-rare doneness (internal temperature of 135-140°F / 57-60°C). If you prefer your lamb cooked to medium, add another 5 minutes to the cooking time, aiming for an internal temperature of 140-145°F (60-63°C).
PRO-Tip: Use a Meat Thermometer: A quality meat thermometer is indispensable here. Insert it into the thickest part of the meat, avoiding the bone, to accurately monitor the internal temperature. This is the absolute best way to ensure your expensive cut of lamb is cooked to perfection.
Resting is Essential: Once your lamb reaches the desired internal temperature, remove it from the oven immediately. Cover it loosely with aluminum foil and let it rest for 10-15 minutes before carving.
PRO-Tip: Understanding Carryover Cooking: During the resting period, the internal temperature of the lamb will continue to rise by about 5-10°F (3-5°C). This phenomenon, known as “carryover cooking,” allows the juices to redistribute throughout the meat, resulting in a more tender, succulent, and evenly cooked final product.
Prepare the Parsley Pesto: While the lamb is resting or beforehand, prepare your fresh parsley pesto. In a food processor, combine fresh parsley, Pecorino Romano cheese, and a garlic clove. With the processor running, slowly drizzle in extra virgin olive oil until a smooth, vibrant green pesto forms. Season with freshly ground black pepper to taste. If the pesto seems too thick, add a tablespoon or so of water and process again until it reaches your desired consistency. This fresh, herbaceous sauce provides a bright counterpoint to the rich lamb.
Carve and Serve: After resting, slice the rack of lamb between the bones to create individual chops. Depending on appetites, plan for two to three chops per person. Serve each tender, herb-crusted chop with a generous spoonful of the vibrant parsley pesto. The combination of savory lamb and fresh, garlicky pesto is truly a small victory for any cook, pleasing even the pickiest palates.

Frequently Asked Questions About Cooking Lamb

When Is Lamb Season?

While lamb is available year-round, its flavor and tenderness can vary by season. Springtime, typically May and June, is when “spring lamb” is most tender and sweet, characterized by a delicate, mild flavor. However, it makes a terrific Easter entree in April as well, especially if the lamb is at least 4 months old. As the year progresses, autumnal lamb, usually from sheep that are older (6-12 months), tends to have a more developed, slightly richer and more complex flavor. Lamb generally refers to sheep that are under a year old, with spring lamb specifically being 3-5 months old.

What’s the difference between a rack of lamb and lamb chops?

A rack of lamb is a specific cut that comes from the rib section of the lamb, typically comprising 8 ribs, often sold as a single piece. Each of these ribs, when cut individually, becomes a lamb chop. So, in essence, lamb chops are individual portions carved from a larger rack of lamb. The rack can be roasted whole for an impressive presentation, then sliced into chops for serving.

What is the safe internal temperature for roasting lamb?

According to the USDA, lamb should be cooked to a minimum internal temperature of 145°F (63°C) for food safety. This yields a medium doneness. However, many gourmets prefer lamb cooked to medium-rare for maximum tenderness and juiciness. For medium-rare, we recommend removing the lamb from the oven when its internal temperature reaches 125°F (52°C). After removal, cover it loosely with foil and allow it to rest for about 10 minutes. During this resting period, carryover cooking will cause the temperature to rise by approximately 10°F (5°C), bringing it to a perfect 135°F (57°C) to 140°F (60°C). If you are serving lamb to very young children, the elderly, or individuals with compromised immune systems, it is crucial to adhere strictly to the USDA’s recommended 145°F (63°C) for safety.

How Do You French the Bones?

Frenching the bones of a rack of lamb means trimming the meat, fat, and connective tissue from the end of the rib bones, exposing about an inch or two of clean bone. The easiest method is to simply ask your butcher to do it for you when you purchase the rack. If that’s not an option, you can do it yourself: using a sharp paring knife, make a cut around each rib bone at the point where the meat begins, then scrape down the bone to remove the meat and fat. While primarily an aesthetic step that gives the rack an elegant presentation, it also allows for more even cooking around the bones. Your lamb chops will still be incredibly delicious even if the bones are not frenched, but it’s a nice touch for special occasions.
