How To Make Garlic Herb Roasted Leg of Lamb

Step 1: Prepare The Lamb

Remove the lamb from the refrigerator:

1–2 hours before roasting

Allowing the lamb to come closer to room temperature helps it cook evenly.

Pat the lamb dry using paper towels.

Trim excess fat if needed, but leave some fat because it adds flavor and moisture.

Step 2: Make The Garlic Herb Paste

In a bowl, combine:

  • Minced garlic
  • Chopped rosemary
  • Chopped thyme
  • Chopped parsley
  • Olive oil
  • Lemon zest
  • Lemon juice
  • Dijon mustard
  • Salt
  • Black pepper

Mix until a thick herb paste forms.

Step 3: Season The Lamb

Using a sharp knife, make small cuts throughout the lamb surface.

Press some garlic herb paste into the cuts.

Rub the remaining herb mixture all over the outside of the lamb.

Allow it to rest for:

30 minutes

to absorb the flavors.

Step 4: Prepare The Roasting Pan

Preheat oven to:

425°F (220°C)

Place:

  • Onion
  • Carrots
  • Celery

in the bottom of a roasting pan.

Add broth and bay leaves.

Place the lamb on top of the vegetables.

Step 5: Roast The Lamb

Place the lamb in the oven at:

425°F (220°C) for 20 minutes

to create a flavorful crust.

Then reduce the temperature to:

325°F (160°C)

Continue roasting until the lamb reaches your preferred doneness.

Approximate temperatures:

  • Rare: 125°F (52°C)
  • Medium Rare: 135°F (57°C)
  • Medium: 145°F (63°C)
  • Well Done: 160°F (71°C)

Cooking time depends on the size of the lamb and your preferred doneness.

Step 6: Rest The Lamb

Remove the lamb from the oven.

Transfer it to a cutting board.

Cover loosely with foil.

Allow it to rest for:

20–30 minutes

Resting allows the juices to redistribute, keeping the meat tender.

Step 7: Make The Pan Sauce

While the lamb rests, strain the roasting juices.

Remove excess fat.

Simmer the liquid until slightly reduced.

For a richer finish, add:

  • Butter
  • Fresh herbs

Taste and adjust seasoning.

Step 8: Slice And Serve

Carve the lamb into slices against the grain.

Arrange on a serving platter.

Drizzle with the herb sauce.

Garnish with:

  • Fresh rosemary
  • Parsley
  • Lemon slices

Serve warm.
