My roasted rack of lamb turns out tender and juicy under a pork panko herb crust that actually stays on through resting and slicing — 0.6g net carbs and 55.6g protein. I sear, brush on Dijon, press the crust, and roast. It feeds 3-4 easily.
I've been making rack of lamb for Christmas dinner since 2018, and I haven't ordered it at a restaurant since. The pork panko crust is what makes this recipe different. I tested regular breadcrumbs, almond flour, and crushed pork rinds side by side over multiple attempts. Regular breadcrumbs slide right off once the juices start flowing during the rest. Almond flour gets soggy within minutes. Pork panko locks on and holds through slicing, every single time.
The method is simple but the order matters. I sear first in a cast iron skillet to build a deep base layer of flavor on the exterior, then do an initial bake at 400 degrees. While the lamb is in the oven, I pulse the pork panko, parmesan, garlic, rosemary, cilantro, and olive oil in the food processor. Then out comes the lamb, on goes a generous brush of Dijon mustard, and I press the herb mixture into the mustard until every surface is coated. One more 5-minute bake and the crust sets up beautifully. The Dijon disappears once the crust firms, but you'd know if it wasn't there. It's the glue that holds everything together and adds a sharp, savory edge underneath.
This is one of those cuts that's naturally keto. Zero carbs in the meat, and with pork panko instead of flour-based breadcrumbs, the whole dish stays low carb with no compromises. I usually serve it alongside keto shepherd's pie when I want to lean into the lamb flavor for a full spread. For something lighter, cilantro lime chicken works as a starter, and air fryer steak bites are my go-to second protein if I'm feeding a bigger group. Creamy pork chops are another option when I want an elegant two-protein table.
One thing I wish I'd figured out earlier: you can prep this ahead. Sear the lamb, let it cool, brush the Dijon and press the pork panko on, then refrigerate. Pull it out 20-30 minutes before baking so it's not ice cold going into the oven. I've done this for every dinner party since I worked out the timing, and it means I'm actually sitting with my guests instead of hovering over the stove.
If the crust starts browning too fast (and with some ovens, it will), tent loosely with foil and pull it off in the last few minutes to crisp back up. I do this almost every time. It's insurance against a burnt crust with a perfect pink interior underneath.
For medium-rare, I pull mine at 132 degrees and let it rest a full 10 minutes. The temperature climbs another 5 degrees while resting, landing right in the 130-140 sweet spot. The edges crisp up golden and almost crackle when you bite in, while the center stays pink and impossibly tender.
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.
Place the lamb on a cutting board fat side up. Score the fat with a knife and season both sides with salt and pepper. Cut the rack of lamb in half with 3 or 4 bones per half depending on the size.
3
Sear the lamb rack
Using a cast iron skillet, or other oven safe pan, heat 2 tablespoons of oil on the stovetop. Sear all sides (about 2 minutes per side) of the lamb rack. Place the pan into the oven for 8 minutes.
4
Make the herb crust
While the lamb is cooking, prepare the crust. Add ground pork rinds, minced garlic, parmesan, 1 tablespoon olive oil, parsley, cilantro, and rosemary to a food processor or blender and pulse for 15 seconds. Pour mixture onto a plate. (Remove leaves off the rosemary sprig and parsley before adding to the food processor or blender. The cilantro can go in with its stem as a large part of the flavor is in the stem. The mixture will be slightly green)
5
Mustard slather
Remove the lamb from the oven and immediately brush generously with mustard until evenly coated.
6
Crust it
Dip the lamb rack into the crumb mixture until coated evenly on all sides. Tap lightly to allow excess to fall off.
7
Last bake
Place the lamb rack back into the oven for 5 minutes. Let rest for 5-10 minutes. Slice and serve immediately. Enjoy!

Frequently Asked Questions
Can I sear the lamb ahead and finish it in the oven later?
I do this for every dinner party now. Sear the lamb, let it cool completely, brush on the Dijon and press the pork panko crust on, then cover and refrigerate. I pull it out 20-30 minutes before baking so it's not ice cold going into the oven. The crust sets up just as well as doing it all at once, and I actually get to sit down with my guests.
How do I reheat leftovers without drying them out?
I reheat leftover lamb in a 300 degree oven with a small splash of stock in the bottom of the pan, covered loosely with foil. Takes about 10-12 minutes to warm through. The crust won't be as crispy as fresh, but the meat stays tender. I've also sliced cold leftovers thin and eaten them over salads, which is my favorite next-day move.
What does frenching the bones mean?
Frenching is when the meat and fat are scraped clean off the ends of the rib bones so they stick up clean and white. It's purely for presentation. I buy mine pre-frenched because cleaning those bones by hand is tedious, but if your butcher doesn't offer it, a sharp paring knife and some patience will get you there. The flavor is identical either way.
Can I use almond flour or regular breadcrumbs instead of pork panko?
I tested all three side by side. Regular breadcrumbs crisp up fine initially but slide off during the rest once the juices loosen the crust. Almond flour gets soggy fast. Pork panko is the only one I've found that grips the Dijon layer and holds through resting and slicing. If you can't find pork panko, crush your own pork rinds in a food processor until they're a fine crumb.
How many people does one rack serve?
One rack gives you eight chops. I usually cut it in half (3-4 bones per section) and figure one section per person for a main course, which means one rack feeds 3-4 people. For a dinner party, I buy two racks and cook them side by side. The timing stays the same.
What temperature should the lamb reach for medium-rare?
I pull my lamb at 132 degrees and let it rest for 10 minutes. The internal temperature climbs another 5 degrees during the rest, landing at 137 which is right in the medium-rare zone (130-140). I've tried pulling at higher temps and the center goes from pink to gray faster than you'd expect. A good instant-read thermometer is worth the investment here.
Why does this recipe use 400 degrees instead of 450 like other recipes?
I've tested both. At 450, the herb crust browns too fast and you end up racing to get the interior to temp before the outside burns. At 400, the sear-first method gives you plenty of exterior color and the lower oven temp lets the crust set gradually without scorching. My crust comes out evenly golden every time at 400. If your oven runs hot, tent with foil midway through.
Crust held together through slicing, which never happens for me!! Annie, I always go to your recipes for company dinners. The Dijon step is doing the work there.
Was skeptical the parmesan was pulling its weight in the crust. It is. Better bind and color than my herb-crumb version, though I’d dial the rosemary back.
The color it gives is what got me too, Riley. Herb-crumb goes flat and pale. One sprig of rosemary is where I land most of the time, two pushes it closer to the edge.
The herb crust softens up when reheated, no way around that. But the Dijon underneath kept the lamb from drying out way better than I expected. I cut the rack into chops before refrigerating so weeknight portions are actually doable, no need to pull out a whole piece. Two minutes in a skillet on medium and the parmesan gets a little toasty again. 55g of protein per serving. It’s in my Sunday prep rotation now even though it still feels like a splurge.
Elaine, it’s the pork panko. Regular breadcrumbs can’t hold through the rest. I tested all three side by side and nothing else grips the Dijon like that.
Making rack of lamb for a dinner party next Saturday and trying to figure out what I can tackle the night before. First question: can the herb crust mixture (pork panko, parmesan, garlic, herbs) be mixed and refrigerated overnight, or does the panko get weird sitting in there?nnAlso curious about the sear. Is it okay to sear a few hours ahead, refrigerate, then brush on the Dijon and press the crust on right before the oven? First time cooking lamb, so I’m not sure what can wait and what has to happen in sequence. Basically trying to map out a timeline so I’m not losing my mind while guests are there.
Roberto, the timeline is close to right, just flip the crust step. Sear, cool completely, then brush on the Dijon and press the panko in before refrigerating. Not right before the oven. The crust needs that time to grip. The dry mix is fine to combine the night before, but I’d add the parsley and cilantro day-of. They lose punch overnight. Pull the lamb 20-30 minutes before baking.
Ask your butcher to french the bones if they aren’t already, I didn’t realize that was an option and spent way too long with a knife. First time cooking rack of lamb and the sear in the cast iron was the step I was most anxious about, but it’s pretty forgiving once the pan is hot enough. The herb crust held all the way through slicing. I’d go lighter on the cilantro next time, just not a fan personally, but the Dijon base is what makes it work.
Cilantro is the one I always second-guess. Back it off to a tablespoon and the Dijon + parsley hold it together. Hope round two goes even better, Donna.
0.6g net carbs finally got me to try rack of lamb. Pressing the pork panko into the Dijon and watching it grip, yeah I held my breath. Freaking proud of how those chops sliced at the table. Does the mustard need to go on right out of the oven, or can it wait a minute while you clear the pan?
Snuck a teaspoon of anchovy paste into the Dijon before spreading. Can’t quite place where that savory depth comes from, and zero fishiness. Doing it every time now.
Anchovy paste does exactly that. I use it in pan sauces for the same reason – zero fishiness but something is definitely happening in the background. Never thought to put it in the Dijon, trying it next time.
Stirred some lemon zest into the Dijon before brushing and swapped the cilantro for mint. Coating came out brighter and cut through the fat better than my first go. Worth trying if your rack’s on the richer side.
My 14-year-old who normally disappears when I start cooking just stood there watching me press the herb crust on. He ate his portion and my husband’s leftovers. Making a double batch for the Fourth.
A teenager voluntarily watching you cook is the review that matters. For the Fourth, sear both racks the night before and refrigerate with the crust already pressed on. Day-of is just the oven.
The sear matters more than I expected, and I almost skipped it the first time because I thought the oven would do enough. It doesn’t. The Dijon goes on when the lamb is still hot from the pan and it sets up almost immediately, so the pork panko crust sticks instead of sliding around during the rest. I also swapped out the cilantro for fresh thyme (if cilantro isn’t your thing, thyme and rosemary together are incredible here) and added a little lemon zest to the mix. The brightness cut right through the richness of the fat cap. Crust came out intact, golden, with real crunch from the parmesan on the edges. Making this for a spring dinner party next weekend and already planning to double the herb coating.
Thyme and rosemary is better for a dinner party crowd anyway, cilantro has too many haters at the table. Doubling the herb coating is right, I always run out.
The pork panko crust held through slicing, which I didn’t expect, and that alone made it worth making again. The cilantro is aggressive though, I’d pull it back or swap for more parsley next time.
My grandmother used to make rack of lamb for Easter every year, and I thought that was just one of those traditions I had to let go after going keto. The fresh rosemary in the herb crust brought back her kitchen so fast I had to put the pan down for a second. Really wasn’t prepared for that. So grateful this recipe exists.
My dad used to make rack of lamb on New Year’s and I honestly thought I’d given that up for good when I went keto. The rosemary and the mustard slather here hit me in a way I wasn’t ready for. Not as perfect as his (still figuring out the sear), but close enough that I cried a little, and that’s worth four stars from me.
That got me. For the sear – really hot pan, fat cap down first, and don’t touch it for 2 full minutes. It releases when it’s ready. Rushing that part is where the color gets uneven.
