Why you’ll love this roasted lamb loin recipe

  • Easy lamb recipe: This recipe requires minimal prep time and is simple to follow, even for beginners.
  • Lean lamb: Lamb cuts can be tough and fatty but this lamb tenderloin is lean and so tender.
  • Spice it up: Just like my Moroccan lamb shanks, adding aromatic spices like za’atar to lamb results in an extra fragrant dish that tastes as good as it looks.

Ingredients and substitutions

Ingredients laid out to make za'atar crusted lamb loin.
  • Lamb loin – Lamb tenderloin is a lean and tender cut of meat that’s equivalent to beef or pork tenderloin. For this recipe, I’m using two lamb backstraps, the eye of the loin. Choose organic grass-fed lamb if possible.
  • Za’atar seasoning – Za’atar is a Middle Eastern spice blend that typically includes thyme, oregano, sumac, sesame seeds, and salt. I use homemade Lebanese za’atar for this recipe but you can also opt a store-bought blend.

See the recipe card for full information on ingredients and quantities.

Variations

Dukkah – A traditional Egyptian blend of nuts, seeds, and warm spices that makes a delicious lamb crust as well.

Lamb dry rub Use my homemade lamb dry rub instead of the za’atar for a spicier twist.

Herb crust – Add chopped fresh rosemary, thyme, and minced garlic on top of the oiled and seasoned lamb loins for a herbaceous flavor.

Serve with a lemon mint cucumber sauce or simply a dollop of homemade Greek yogurt.
