Roasted Rack of Lamb

Why This Pork Panko Herb Crust Actually Works

I’ve made herb crusted lamb more times than I can count, and the pork panko is what finally solved the crust problem. Every other version I tried (regular breadcrumbs, almond flour, even crushed crackers) fell apart during the rest or turned soggy by the time I sliced. Pork panko grips the Dijon layer and holds. Add in parmesan, garlic, fresh rosemary, and cilantro, and the crust has enough flavor that you don’t need a sauce. This is a keto centerpiece that takes about 30 minutes of active time, and the sear-then-oven method gives you a tender interior with a crust that crunches. If you like crispy pork panko coatings, my keto chicken katsu uses the same technique on chicken.

What You're Working With

A lamb rack is eight unseparated chops cut from behind the shoulder and in front of the loin. It’s a naturally tender cut with a robust, slightly grassy flavor from the fat cap. The fat is what makes this cut perfect for low carb cooking because the meat itself has zero carbs and the marbling keeps everything juicy through cooking. I score the fat cap before searing so it renders evenly and creates more surface area for the crust to grip.

How Many People Does It Feed

One lamb rack has 8 chops and feeds 3-4 people depending on appetites. I cut mine in half with 3-4 bones per section. If you need more, you can cook two racks side by side with no change to the timing. There’s also a double rack option (meat on both sides of the bones, giving you 16 chops) and a crown roast, where you tie two or more single racks together so the ribs form a dramatic upright circle. I’ve done the crown for Thanksgiving and it makes a statement on the table, but the single rack with the herb crust is what I come back to most. For other proteins that impress at a dinner party, my boursin chicken and bacon wrapped pork chops are the two I rotate with this.

How I Make It

• Prepare the Lamb
  I place the lamb fat side up on a cutting board and score the fat in a crosshatch pattern with a sharp knife. Season both sides generously with salt and pepper. I usually cut the rack in half with 3-4 bones per section. Pull it out of the fridge 20-30 minutes before cooking so it comes closer to room temperature. This makes a real difference for even cooking. If the center is ice cold, you’ll end up with an overdone crust and a raw middle.

• Sear the Lamb
  Heat oil in a cast iron skillet on the stovetop. I sear each side for about 2 minutes until I get a deep golden crust. Don’t rush this step. That initial sear is where most of the flavor lives. Once all sides are seared, the skillet goes straight into a 400 degree oven for 8 minutes.

• Make the Herb Crust
  While the lamb bakes, I prep the crust. Pork panko, minced garlic, parmesan, olive oil, parsley, cilantro, and rosemary go into the food processor for a quick 15-second pulse. Pour it onto a plate. I pull the leaves off the rosemary sprigs and parsley stems before processing (rosemary stems are tough and bitter). The cilantro goes in stem and all because the stems carry most of the flavor. The mixture will look slightly green.

• Coat with the Crust
  Once the lamb comes out of the oven, I brush Dijon mustard generously over every surface until it’s evenly coated. Then I press the lamb into the herb mixture on the plate, turning to coat all sides. Give it a light tap to shake off any excess. The Dijon acts as glue, and the crust will set during the final bake.

• Final Bake and Rest
  Back into the oven for 5 minutes. Then out, and I let it rest for a full 10 minutes before slicing. Resting is non-negotiable. The juices redistribute and the temperature climbs another 5 degrees. If the crust starts browning too fast at any point, tent loosely with foil and pull it off in the last couple minutes to re-crisp.

Internal Temperature Guide

This recipe lands at medium-rare, which is where I think lamb tastes best. I pull mine at 132 degrees and rest for 10 minutes, which brings the final temp to about 137. If you prefer a different doneness, here’s what to aim for:

Rare: 120-130 degrees F

Medium-Rare: 130-140 degrees F (bright pink)

Medium: 140-145 degrees F (light pink)

Medium-Well: 145-150 degrees F

Well-Done: 150-160 degrees F

The resting time is non-negotiable. I know it’s tempting to slice right away, but those 10 minutes let the juices redistribute and the temperature climb another 5 degrees. If you skip the rest, the juices run out onto the cutting board instead of staying in the meat.

Lamb Chops vs. the Full Rack

People sometimes confuse lamb chops with a full rack, and they’re not quite the same thing. Lamb chops can come from the rib, loin, or shoulder. A full rack is specifically the rib section with all eight chops connected, which is what this recipe calls for. I prefer cooking the full rack because the connected bones insulate the meat and give you a more even cook. You get better browning on the fat cap and the bones act as a natural handle for the herb crust. Once it’s rested, I slice between the bones for individual servings.
