Grilled Rosemary Garlic Leg of Lamb for Easter Dinner
A smoky, charred take on the classic Easter roast, this grilled leg of lamb is rubbed with a bright rosemary-garlic marinade and cooked over two-zone heat for juicy, medium-rare slices. Faster than a traditional oven roast, it delivers the same celebratory flavor with a crisp, grilled crust.
Jake's note
"This grilled leg is perfect for Easter or any springtime gathering — it gives you roast-like richness with a welcome smoky char. Home cooks will love how the simple rosemary-garlic rub transforms a classic into a faster, grill-friendly centerpiece."
Grilled Rosemary Garlic Leg of Lamb for Easter Dinner
This grilled rosemary-garlic leg of lamb takes the traditional Easter centerpiece and gives it a bright, slightly smoky twist that still reads celebratory on the table. The rosemary and garlic marry with lemon and Dijon to cut through the lamb’s richness, while a quick, high-heat sear builds the browned, slightly charred crust we crave without overcooking the interior. Using a bone-in leg keeps the slices juicy and adds flavor as the meat finishes over indirect heat, so you get clean medium-rare slices with an herb-forward punch.
What makes this version work is the balance of technique and timing: a short marinade to impart flavor without chemically “cooking” the surface, a purposeful crosshatch on the fat to render and crisp evenly, then moving from a hot sear to lower indirect heat so you don’t lose the pink, tender center. It’s faster than a slow oven roast but delivers all the hallmarks of a holiday roast—slices that look beautiful on a platter, pan juices to spoon over each serving, and aromatics that fill the yard as the grill lid lifts. This recipe suits host-cooks who want an impressive roast with predictable results and minimal fuss.

Ingredients
Instructions
Make the rosemary-garlic marinade and prep the lamb
For this step
- 4 lbBone-in leg of lamb
- 0.25 cupExtra-virgin olive oil
- 6 clovesGarlic, minced (about 6 cloves)
- 3 tbspFresh rosemary, finely chopped
- 1 itemLemon (zest and juice)
- 2 tbspDijon mustard
- 2 tspKosher salt
- 1 tspFreshly ground black pepper
Marinate and come to room temperature
Prepare the grill for two-zone cooking
Sear the lamb over direct heat
Finish over indirect heat to desired doneness
Rest, carve, and serve
Tips from the kitchen
Score the fat properly
Make shallow crosshatch cuts through the fat only so the marinade and heat render the fat without cutting into the meat itself.
Use a probe thermometer
Insert it into the thickest part near the bone and watch for 125–130°F for medium-rare, remembering carryover will raise it another 5–10°F while resting.
Protect garlic from burning
Smear the marinade on before searing but avoid leaving excessive minced garlic directly on the hot grate when searing to prevent bitter char.
Let meat rest fully
Tent loosely with foil for 15–20 minutes to let juices redistribute; carving too soon squeezes flavorful juices onto the board.
Two-zone grill control
Calibrate your hot and indirect zones before you start so you can sear quickly and move the leg away to finish at a steady lower temperature.
Variations & substitutions
Mint-Dijon Finish
Mix chopped fresh mint and a touch more Dijon with olive oil and spoon over slices right before serving for a classic, bright contrast.
Mediterranean Herb Crust
Add chopped oregano and thyme to the marinade and press a thin layer of panko mixed with grated lemon zest onto the surface before searing for extra texture.
Citrus-Honey Twist
Swap half the lemon for orange juice and stir a tablespoon of honey into the marinade for a sweeter, glazed flavor that caramelizes while searing.
Boneless Leg Adaptation
Use a boneless leg but reduce indirect cooking time by about 10–15 minutes and check temperature in the thickest part for doneness.
Storage & make-ahead
Store leftover sliced lamb in an airtight container in the refrigerator for up to 3–4 days; keep juices and a little fat with the meat to prevent drying. For longer storage, freeze tightly wrapped slices for up to 3 months. Reheat gently in a 275°F oven covered with foil until warmed through (about 10–15 minutes) or slice thin and warm briefly in a hot skillet with a splash of broth to preserve tenderness.
What to serve with it
Serve thin slices across the grain with spooned pan juices or a bright mint chimichurri to cut the richness. Pair with roasted new potatoes tossed in rosemary, charred asparagus or spring peas, and a simple lemony salad; for wine, choose a medium-bodied red like Grenache or a structured rosé to complement the herb and char flavors. Present the bone-in roast on a wooden board with lemon wedges for guests to squeeze at the table.
Frequently asked questions
Can I marinate the lamb overnight?
Yes—overnight marinating (up to 18 hours) deepens the herb and garlic flavor, but don’t marinate much longer or the lemon can start to change the texture of the surface.
How do I know when it’s done without a thermometer?
While I strongly recommend a thermometer, you can press the meat to compare firmness—soft equals rare, slightly springy gives medium-rare—but this is less reliable, especially with bone-in pieces.
What if my garlic blackens while searing?
If bits of garlic char, scrape them off and continue searing the meat itself; bitter burnt garlic won’t be pleasant, so keep the sear brief and focused on the fat and exterior, not the minced garlic.
Can I add smoke for more flavor?
Absolutely—add a handful of soaked wood chips to a gas smoker box or push coals to one side in a charcoal grill to introduce mild smoke; keep it subtle so it doesn’t overpower the rosemary and lemon.
Should I carve before or after resting?
Always rest first—carving immediately will bleed juices onto the board and yield drier slices; after a 15–20 minute rest, carve thinly across the grain for best tenderness.
