ROAST LEG OF LAMB

This delicious and easy lamb recipe is perfect for holiday dinner even if it’s your first time making Leg of Lamb. If you follow some simple guidelines and tips below, you can easily get a flavorful roast lamb every time. There is also a step by step if it’s your first time carving a Leg of Lamb.

One of the most important keys to cooking a beautiful Roast Leg of Lamb is to buy your lamb leg from the butcher and not from the grocery store meat aisle. You want a fresh young (but not too young) lamb and to have the butcher trim the thick outer layer of fat off to make sure it won’t taste like older, tougher mutton.

You can ask the butcher to include the lamb shank but it’s not necessary, unless you plan on using the bones to make a stock later. You do want a bone in lamb for a more naturally flavorful Roast Leg of Lamb, but the shank is more for looks.

Leg of Lamb doesn’t need a marinade, it is a naturally tender cut so leaving in a marinade too long can actually make the meat tougher. Herbs like fresh rosemary or sprigs of thyme plus garlic cloves are enough to make a flavorful lamb roast that is tender and juicy, and easier for you to make!

The cooking time for this Leg of Lamb recipe is for a medium rare to medium roast lamb. Like a Prime Rib, a whole leg of lamb is a large cut of meat so there will be a few cuts that are rare and medium well so your Easter dinner guests are sure to get the cut they like best.

Roast Leg of Lamb goes best with side dishes that won’t overpower the rustic, naturally flavorful roast lamb. For a simple and delicious Easter Dinner, serve Leg of Lamb with Parmesan Smashed PotatoesRoasted Vegetables, and French Bread Rolls. Mint jelly is a traditional topping for Leg of Lamb, use the bonus recipe below to turn a store bought mint jelly into a tasty sauce.

Can you make Roast Leg of Lamb in the Slow Cooker?

To make Slow Cooker Leg of Lamb, use a bone in lamb leg about 4 pounds. Prepare and season the lamb according to the recipe instructions. Place lamb in slow cooker. Add 2 cups beef stock to the slow cooker around the lamb. Cook on low for 10 hours. Remove from slow cooker and place lamb fat side up in roasting pan. Drizzle oil on lamb and bake at 400 degrees for 15-20 minutes to brown.

MINT JELLY SAUCE TO SERVE WITH ROAST LEG OF LAMB

  • Ingredients: 2 tablespoons sugar, 1/2 cup water, 1/4 cup vinegar, 1 jar mint jelly, 1/3 cup minced mint leaves, 1 tablespoons lemon juice
  • Simmer sugar, water, and vinegar in a sauce pan over medium low heat for 5 minutes.
  • Whisk in mint jelly until well combined.
  • Stir in lemon juice and mint. 
  • Serve alongside Roast Leg of Lamb or store for up to 1 week in the refrigerator.

HOW TO CARVE ROAST LEG OF LAMB

    • After the lamb has rested for 15 minutes, place on a clean cutting board. 
    • The bone runs fairly close to the middle at an angle, so you can start carving either side of meat.
    • Slice the roast lamb meat across the grain. Cut straight down to the thickest part of the meat until you reach the bone (like a bone in ham). The cuts are going to be perpendicular to the bone (like a lowercase t) and the meat will still be attached.
    • To cut the slices off of the bone, turn your knife so it’s going the same direction of the bone. Starting at the furthest end of the bone, cut slices off the bone keeping knife close to the bone.
    • If there is leftover meat on the bone, carefully slice off or use bone for a rich stock for Lamb Stew.
