A rack of lamb is so impressive in appearance, that I’ve always assumed it a process reserved for experienced chefs. Probably fussy, probably difficult.
If you’ve never prepared rack of lamb for this reason, I hope you’ll give this oven roasted rack of lamb a try. It’s a very easy dinner to prepare.
Lamb can be so forgiving. It’s good rare, medium, and well-done, and its exterior develops a crispness that rivals that of the skin of pork and chicken, or the exterior of perfectly grilled beef. And it will do this all without much fuss.
For this recipe, which I learned in Culinary School, we’re using a rack of lamb marinade with rosemary and thyme. After the marinade, we’re searing it stove top, then slathering both sides with Dijon mustard.
The final step is pressing on a panko bread crumb and ground pistachio mixture to finish in the oven.
Keep this one in your back pocket when you’re looking for easy and special recipes for Easter dinner.
Let’s take a look.
Colorado has a strong ranching heritage and lamb plays a big part in our history. Colorado Lamb is highly sought after due to its quality, and consistency in flavor and tenderness. The majority of lamb are free range, grazing on grass, brush and sage in the foothills of the Rocky Mountains. And even graze in Colorado Vineyards. Colorado lamb is hormone and antibiotic free.
Lamb raised and imported from New Zealand and Australia are smaller in size that American raised lamb, and bring with it a gamier flavor. Please support local. Ask your butcher for Colorado raised lamb.
Preparing a Frenched Rack of Lamb
At Cooking School, we prepped a Frenched rack of lamb. New for me. After being handed a rack of lamb we were instructed to clean the bones using the “frenching” method. It truly was a labor of love, and a very difficult task.
I wrestled with that chunk of meat for over an hour, and I swear there was a moment where I thought I’d cry out of frustration.
Frenching a rack of lamb means to strip meat and membrane away from the bone to give it a clean appearance. See that beautiful little clean handle – that takes a lot of work.
Our knife skill training at school was extensive and I’m very glad for that. However my boning knife and I still aren’t speaking over the whole ordeal. Here’s a link from Serious Eats if you’re interested in learning Knife Skills, How to Clean and French a Lamb Rack.
Pro Tip: Purchase a rack of lamb that has already been Frenched by your butcher. You’ll gladly pay those few extra dollars to save an hours worth of tedious work.
Ingredients You’ll Need

- 1 – 1 pound rack of lamb, Frenched
- Pistachios: Purchase shelled pistachios that are roasted.
- Spices: Dried rosemary and thyme combined with olive oil makes the best lamb marinade = easy.
- Dijon Mustard: Dijon brings a beautiful flavor, plus acts as the “glue” to hold the panko bread crumb and ground pistachio mixture. An added benefit of mustard, is that it also tenderizes the meat.
Tip: When calculating how much rack of lamb will feed your crowd, when sliced, one rack of lamb has 8 chops. Plan on 2 chops per person. Although the chops are small, the side dishes will fill in to make an ample meal for each person.

Rack of Lamb Cooking Time
Roast your rack of lamb in a 400 degree pre-heated oven. Roast time will vary because oven temperatures are not always reliable. But you can estimate about a 20 – 30 minute cook time.

Since the internal temperature of cooked lamb will rise 5 – 10 degrees during the rest period, adjust accordingly by pulling the lamb out of the oven when its 10 degrees lower than desired doneness.
