Roasted Leg of Lamb

If you haven’t cooked a leg of lamb before, don’t be intimidated. I know it seems incredibly daunting but it’s so much easier than you think. This roasted leg of lamb recipe here is fool-proof and fuss-free, I promise. And you don’t even need a long drawn-out ingredient list.

Nope, the ingredient list is super simple here.

Ingredients

Leg of lamb

Bone-in will have extra flavor.

Garlic

Adds a lovely buttery flavor profile.

Olive oil

This will serve as the rub for your lamb. We recommend using good quality olive oil here such as California Olive Ranch (our favorite).

Fresh herbs

Chopped fresh rosemary and thyme are common pairings with leg of lamb but you can also improvise with some of your favorite herbs.

Dijon

Adds a sharp, tangy flavor to your lamb rub, balancing out the rich taste of the lamb meat.

Salt and pepper

Season generously! 1/2 – 1 teaspoon kosher salt is recommended per pound of lamb.

Now I left the shank on for it’s dramatic presentation but you can easily purchase one with the shank removed – there’s no advantage here except for the aesthetic eye for serving.

Marinating is also not needed here – you’ll see that the simple garlic mixture rub will bring in so much flavor. And it’s sure to be a crowd-pleaser for your Easter holiday or next dinner party, impressing all your guests with such minimal effort. It also pairs perfectly with these mini hasselback potatoes!

tips and tricks for success

  • Go to a reputable butcher. Cooking such a large cut of meat can be daunting! We recommend purchasing a leg of lamb that is preferably grass-fed and organic. Ask for market weight, avoiding baby lamb or mutton. The butcher can also trim the excess fat.
  • Bone-in is ideal. Bone-in will have extra flavor, but if you are nervous about carving and serving, boneless can be used.
  • Fresh herbs are best. Although you can certainly substitute dried herbs, fresh herbs are key here, delivering the best kind of flavor.
  • Use an instant-read thermometer for the most accurate results. Check your lamb halfway through cooking, inserting through the thickest part of the meat but avoiding the bone. The internal temperature should reach 135°F for medium.
  • Let your meat rest. As with any large cuts of meat, let your lamb rest for at least 15 minutes prior to serving, allowing the juices to redistribute – this will allow for maximum flavor and juiciness.

Roasted Leg of Lamb: Frequently Asked Questions

Which is better, boneless or bone-in leg of lamb?

Bone-in will have more flavor, but boneless will be much easier to carve. If purchasing boneless, we recommend purchasing oven-safe kitchen twine as the lamb will need to be tied together.

Do I have to marinate the leg of lamb?

Because a leg of lamb is so naturally tender, marinating is not necessary.

Can I use dried herbs instead?

Absolutely! But because dried herbs are often more potent/concentrated than fresh herbs, you need less when using dry. The correct ratio is 1 tablespoon fresh herbs to 1 teaspoon dried herbs.

How long should I cook the leg of lamb?

This really depends on personal preference. We recommend medium (135°F, 20 minutes per pound) but you can also cook to rare (125°F, 15 minutes per pound), medium well (145°F, 25 minutes per pound) or well done (155°F, 30 minutes per pound).

Can I freeze leftover lamb?

Yes! Leftover lamb can be stored in an airtight container for 1-2 days in the fridge, and frozen in slices wrapped in aluminum foil, reheating at 350°F (still wrapped) until warmed through.
