Ingredients You’ll Need

For this Garlic Rosemary Roast Leg of Lamb Recipe, I like to keep things fresh and simple—using fresh herbs and garlic really elevates the lamb’s natural flavors. When shopping, look for a good quality boneless leg of lamb, preferably from a trusted butcher, and fresh herbs that smell vibrant.

• Boneless leg of lamb: Choosing a boneless cut makes roasting and carving so much easier—and it absorbs flavors beautifully.
• Fresh garlic: Freshly grated garlic adds an incredible punch that you just can’t get from pre-minced jars.
• Olive oil: Use a good quality extra virgin olive oil for the best flavor and to help the herbs adhere to the meat.
• Fresh rosemary: Mince this finely so it evenly distributes and infuses the lamb.
• Fresh mint: I discovered that a little mint adds a subtle brightness that balances the richness.
• Kosher salt: Essential for seasoning deeply and enhancing the lamb’s flavor.
• Cracked black pepper: Adds just the right amount of heat and texture.
• Extra garlic heads (optional): Roasting whole garlic heads alongside the lamb mellows their sweetness—such a treat to eat!
• Fresh rosemary sprigs (optional): Great for roasting around the lamb to add aromatic magic during cooking.

Variations

While I love the classic garlic and rosemary combo, this Garlic Rosemary Roast Leg of Lamb Recipe is a flexible canvas. Feel free to make it your own—it’s always fun to experiment with herbs or adjust seasoning to match your palate.

• Herb Mix-Up: I sometimes swap fresh mint for thyme or oregano, which also adds a lovely earthy flavor. My family actually prefers thyme in the fall!
• Spice It Up: For a little extra kick, add crushed red pepper flakes or a touch of smoked paprika to the rub—turns the roast into a mild spicy delight.
• Garlic Lovers’ Dream: Double the garlic or stuff slivers of garlic into small incisions in the meat for a deeper infusion.
• Marinade Magic: If you have extra time, marinate the lamb overnight in the garlic-herb oil mixture to boost flavor intensity.

How to Make Garlic Rosemary Roast Leg of Lamb Recipe

Step 1: Prep Your Oven and Meat

Start by preheating your oven to 325°F. While it warms, pat your boneless leg of lamb dry with paper towels—this helps the herb rub stick better and allows for better browning. I always find that a dry surface is key to developing that gorgeous crust we’re aiming for.

Step 2: Make the Garlic Rosemary Herb Rub

In a small bowl, mix grated garlic, olive oil, minced fresh rosemary, fresh mint, kosher salt, and cracked black pepper until fully combined. This fragrant paste is the flavor bomb for your lamb—get ready for your kitchen to smell amazing! Use your hands or a spoon to rub this mixture all over the entire leg of lamb, making sure every surface is lovingly coated.

Step 3: Add Extra Garlic and Rosemary

If you’re using whole garlic heads and rosemary sprigs, tuck them around the lamb in your roasting pan or cast iron skillet. This trick adds an extra layer of aroma and infuses the meat subtly as it roasts.

Step 4: Roast Your Leg of Lamb

Pop the lamb into the oven and roast for about 20 minutes per pound for medium-rare. For the 5-pound roast, I roasted mine for 100 minutes. Keep an eye on the internal temperature if you have a meat thermometer—it should be around 135°F for medium-rare, and the meat will continue to cook while resting.

Step 5: Rest and Slice

This step is crucial: let the roast rest for 15-20 minutes once out of the oven. Resting lets the juices redistribute so when you slice, you won’t lose that beautiful moisture. After resting, carve into thick, juicy slices and prepare for the compliments!

How to Serve Garlic Rosemary Roast Leg of Lamb Recipe

Garnishes

I love garnishing this roast with a few sprigs of fresh rosemary and some roasted garlic cloves from the pan—it not only looks lovely but invites extra aroma right at the table. Sometimes, a sprinkle of flaky sea salt right before serving adds that perfect finishing touch.

Side Dishes

My go-to sides include creamy mashed potatoes, roasted root vegetables like carrots and parsnips, or a vibrant salad with lemon vinaigrette. On some occasions, I pile slices of lamb on warm flatbreads with homemade tzatziki sauce—my family goes crazy for this casual twist!

Creative Ways to Present

For special gatherings, I’ve arranged the sliced roast in a beautiful spiral on a serving platter, garnished with fresh herb sprigs and lemon wedges for color contrast. Another favorite is serving the lamb as sliders with garlic aioli and arugula on mini buns—it’s always a hit with kids and adults alike!

Make Ahead and Storage

Storing Leftovers

I store leftover lamb tightly wrapped in foil or an airtight container in the refrigerator, where it keeps well for 3-4 days. This way, the meat stays moist and flavorful for quick meals during the week.

Freezing

If I want to keep it longer, I slice the roast and freeze portions in freezer-safe bags, separated by parchment paper so slices don’t stick together. This makes reheating just a portion super convenient.

Reheating

To reheat, I gently warm slices in a low oven (around 275°F), covered loosely with foil to avoid drying out. Alternatively, reheating in a skillet with a splash of broth keeps the lamb juicy and flavorful.
