What Is A Rack of Lamb?
A rack of lamb is a connected series of rib chops—similar to a beef rib roast but smaller and more delicate. The meat is naturally tender and is best served rare to medium-rare. Presented whole, it makes an elegant, easy-to-cook centerpiece.
Ingredients You’ll Need
This recipe uses just a few simple ingredients that combine for a big flavor payoff. Here’s what you’ll need:
- Breadcrumbs: Regular breadcrumbs, panko, or even pork rind crumbs work well.
- Herbs: Crushed dried rosemary and thyme. Fresh herbs can be used if finely chopped.
- Garlic powder: For a concentrated savory note.
- Olive oil: Or a neutral oil of your choice.
- Lamb rack: One 8- to 10-bone rack (about 1.5–2 lb), trimmed and frenched. Bring to room temperature before cooking for even results.
- Salt and black pepper
- Garlic: Four cloves, crushed.
- Mustard: Dijon is recommended, but use your preferred variety.
How to Cook A Rack Of Lamb
Because the lamb cooks quickly, prepare side dishes ahead or start them before you begin the lamb. Follow these steps for consistent results:
- Preheat and mix: Preheat the oven to 450°F and position the rack in the center. In a dish or bowl, combine 1/2 cup breadcrumbs, 1 tsp crushed dried rosemary, 1 tsp dried thyme, 1 tsp garlic powder, and 2 tbsp olive oil; mix until moistened.
- Season and sear: Pat the lamb dry and season with salt and pepper. Heat 2 tbsp olive oil in a large oven-safe skillet over high heat. Add crushed garlic, then sear the rack for 1–2 minutes per side until browned.
- Coat and prepare to roast: Remove the skillet from heat, brush the lamb with 2 tbsp Dijon mustard, and press it into the breadcrumb mixture to coat. Return the rack to the skillet and cover the exposed ribs with foil to prevent burning.
- Roast: Roast 15–22 minutes, or until an instant-read thermometer registers 125°F for rare or 135°F for medium-rare. Begin checking at about 15 minutes—internal temperature is the most reliable indicator.
- Rest and carve: Transfer the lamb to a cutting board and loosely tent with foil. Rest 10 minutes to let juices redistribute, then cut between the ribs into chops. Garnish with parsley if desired and serve.
Should I Cut the Rack of Lamb Before Cooking?
Generally, cook the rack whole and carve after resting. If your rack isn’t frenched, you may prefer to have it frenched or remove excess fat and silver skin, but portioning into individual chops before cooking is not necessary and can dry the meat.
Helpful Tips
- Choosing quality lamb: Pick racks with rosy-pink meat and a clean white fat cap. Avoid dark red meat or discolored fat.
- Frenched vs. unfrenched: Frenched racks offer a classic presentation and easy handling, but leaving the rib meat intact is a matter of preference—both taste great.
- Portioning: Plan around 2–3 chops per person. For larger groups, prepare a second rack.
Serving Suggestions
The lamb is the star, so simple, complementary sides work best. Consider:
- Roasted carrots: Sweet, caramelized carrots pair well with the savory lamb.
- Potatoes: Baked, roasted, or creamy mashed potatoes are classic accompaniments.
- Grilled or roasted vegetables: A medley of seasonal vegetables brightens the plate and balances the richness.
How to Store and Reheat Leftover Lamb
- Store leftovers in an airtight container or wrapped well in the refrigerator for up to 3 days, or freeze for up to 2 months. Thaw frozen lamb in the refrigerator before reheating.
- Reheat gently over medium heat in a covered skillet with a splash of water or broth to keep meat moist; avoid high heat to prevent overcooking.
