What Type of Lamb Should I Use?

Choosing the right rack of lamb can make your life, and this dinner recipe, so much easier! I always buy Frenched racks of lamb from my local grocery store. A ‘Frenched’ rack of lamb will already have the rack of bones cleaned and the fat and tissue removed. It makes for a clean presentation at the dinner table. If the rack has too much fat left on the top side for your taste, use a sharp fileting knife to remove the excess fat. I usually get my lamb at Costco; it’s grass-fed, organic lamb and it has minimal gamy flavor. Whole Foods and Safeway are also great options.

Garlic, Herb & Mustard Spread

Even if you don’t typically enjoy lamb, you’ll love this roasted rack of lamb recipe because of the seasonings! I season the lamb with a homemade spread made with garlic, rosemary, thyme, mustard and olive oil. The garlic and herb flavor pair so well with lamb meat! I just place everything into a food processor and pulse the ingredients into a thick paste. Don’t have a food processor? You can finely mince the garlic and herbs, then combine with the rest of the ingredients in a bowl. You can even make this spread ahead of time if you want to save time!

Prepping the Rack of Lamb

Once I have my spread ready to go, it’s time to prepare the rack of lamb. First, I remove the lamb from it’s packaging and pat it dry with paper towels, then place the lamb onto a baking sheet lined with parchment paper. Next, I use a spatula to spread the garlic and herb paste all over the lamb, especially on the top side. Once the lamb is dressed, it needs to rest at room temperature for about 1 hour.

You can also season the lamb the night before and keep it stored in the refrigerator. Remove the lamb about 1 hour before roasting to allow the temperature of the meat to rise.

Roasting & Resting Lamb

Lamb ready to roast? First, preheat the oven to 450F. I always like to have my oven preheated for at least 15 minutes before roasting. This recipe requires a little bit of flipping to ensure the best results. I roast my rack of lamb for 10 minutes with the fat side facing up, then flip it and roast on the other side for 10 minutes. And one final flip back over and I let the lamb finish roasting with the fat side up. The spread likes to stick to the parchment paper sometimes! If that happens, just use a small, off-set spatula to spread it back onto the lamb.

The timing for this recipe really depends on how thick your rack of lamb is. Small, thin racks of lamb will roast in 25 minutes, thicker racks can take up to 40 minutes. I like my lamb cooked to a medium-rare, which is 125F to 130F. For a medium doneness, roast until the internal temperature reaches 14oF to 145F. Once the lamb is done roasting, allow it rest on a carving board for at least 5 to 10 minutes before slicing and serving.

Creamy, Garlicky Tzatziki Sauce

You’re going to want this creamy, garlicky sauce with everything!! My easy tzatziki sauce is the perfect complement to the roasted lamb chops! It’s super easy to make, too! First, I peel and grate a large cucumber, season it with salt, wait 5 minutes and then wring out all the liquids. The salt will help draw out more of the cucumber juices. Next, I combine the yogurt, garlic, mint, dill, olive oil and the grated cucumber in a food processer and pulse everything together.  I usually have at least a quarter cup of this sauce with my lamb, it’s that good!

Easy Dill, Mint & Basil Tomato Cucumber Salad

Since roasted lamb can be quite rich and fatty, I love to serve a refreshing side of salad. This easy cucumber and tomato salad is seasoned with basil, mint and dill, which complement the flavors of the tzatziki sauce! Just chop a few cucumbers, tomatoes and shallots, then add a stack of fresh herbs, salt and pepper. I dress the salad simply with lemon juice and extra virgin olive oil.

I recommend waiting to dress the salad until you’re ready to serve. If you dress it too early with the salt, lemon juice and olive oil, the juices from the tomatoes and cucumber will run and cause the salad to be extra juicy and watery.

Oven-Roasted Baby Potatoes

And for a starchy side dish to complement the roasted rack of lamb, I love to make my easy ‘Oven-Roasted Potatoes’! The potatoes are dressed with garlic, thyme, parsley and little bit of parmesan cheese. They’re roasted to perfection and golden! Make sure to check out my video recipe for these potatoes. You can enjoy them with just about any main entrée!

I like to make these roasted potatoes while I’m waiting for my seasoned lamb to rest. Once they’re done, I keep them warm on the stove top until I’m ready to serve.
