Grilled leg of lamb is one of those dishes that turns simple ingredients into something unforgettable. A Cuban mojo marinade of citrus, garlic, oregano, and cumin penetrates the meat while high-heat grilling builds a deeply caramelized crust around a buttery, medium-rare center. Butterflying the lamb helps it cook evenly, honoring Mediterranean and Caribbean grilling traditions while delivering bold flavor in less time. Serve it with rice or roasted potatoes alongside your mojo sauce, Cuban black beans, and a grilled vegetables salad.
It’s a smooth, slow jam for your taste buds, turning any dinner into a soulful celebration, especially that jazzed up soul food Christmas menu. Let this grilled Easter lamb take you on a flavor journey that’ll have you coming back for an encore!
How I Grill Leg of Lamb
I always start with a butterflied leg of lamb because it grills more evenly and gives me maximum surface area for char. My Cuban mojo marinade isn't just about seasoning the meat; the citrus, garlic, oregano, and cumin work together to mellow lamb's richness while adding layers of bright, savory flavor. I let it marinate overnight whenever possible because time makes a noticeable difference.
Before grilling, I pat the lamb completely dry. That's one mistake I see often. Wet meat steams instead of searing, and you miss out on that flavorful crust every grilled leg of lamb deserves. I grill over direct high heat just long enough to develop color, then finish over indirect heat until the thickest part reaches about 130°F for medium rare. A meat thermometer isn't optional here. Overcooked lamb loses both its tenderness and its personality.
Resting is just as important as grilling. Give it at least 10 minutes before slicing across the grain. Those juices stay where they belong, leaving every slice juicy instead of running across the cutting board.
To dial up flavor even more, I reduce a portion of the reserved marinade into a finishing sauce or brighten everything with fresh citrus zest and flaky salt just before serving. The contrast between the smoky crust, tender interior, and vibrant mojo is exactly what makes this grilled lamb recipe one I come back to again and again.
Beats and Eats (music to pair with leg of lamb)
David Ruffin's song "Slow Dance" moves with the same confidence as this grilled leg of lamb, letting warm melodies, silky harmonies, and an unhurried groove slowly build emotional depth the way the mojo marinade gradually transforms the meat. The smoky char, bright citrus, rich lamb, and lingering garlic notes unfold like Ruffin's soulful phrasing, proving that both great songs and great barbecue reward anyone willing to let them develop at their own pace.
What Is Cuban Mojo
Cuban mojo is a flavorful citrus garlic marinade and sauce used in Cuban cuisine, known for its bright, tangy, and garlicky flavors. The key ingredients typically include sour orange juice (or a mix of orange and lime juices), plenty of fresh garlic, olive oil, oregano, and sometimes cumin. The combination of citrus and garlic gives mojo its signature zesty and savory profile.
Mojo is often used to marinate meats like pork, chicken, or lamb, adding a fresh, vibrant flavor to grilled or roasted dishes. It can also be drizzled over vegetables, used as a dipping sauce for tostones (fried plantains), or mixed into rice and beans. Its versatility and bold flavors make it a staple in Cuban cooking.
Cuban Mojo Sauce Ingredient Notes
Fresh Garlic
Garlic is the backbone of authentic Cuban mojo, delivering its unmistakable savory bite and aroma. I prefer freshly minced cloves over pre-minced garlic because they release more essential oils and create a brighter, more complex sauce. If the garlic tastes overly sharp, let the mojo rest for 20 to 30 minutes before serving to mellow its edge.
Sour Orange Juice
Fresh sour orange juice gives mojo its signature tangy, slightly bitter citrus profile that balances rich meats like lamb and pork. If you can't find sour oranges, combine fresh orange juice with lime juice and a splash of grapefruit juice for a close approximation. Always use freshly squeezed juice for the cleanest flavor.
Fresh Oregano
Fresh oregano contributes earthy, peppery notes that define the herbaceous character of Cuban mojo. If using dried oregano, reduce the amount by about half since its flavor is more concentrated. Bruise fresh leaves slightly before chopping to release their aromatic oils.
Ground Cumin
Cumin adds warm, nutty depth that rounds out the bright citrus without overpowering it. Toast whole cumin seeds and grind them yourself if you want even more complexity, but freshly opened ground cumin is an excellent shortcut.
Extra Virgin Olive Oil
Olive oil binds the citrus and spices into a silky sauce while softening the acidity. Use a good-quality extra virgin olive oil with a fruity profile rather than a heavily peppery one, allowing the citrus to remain the star. Whisk it in gradually for the smoothest consistency.
Ways to Make It Even Better
- Let the mojo sit for at least 30 minutes before serving so the flavors meld together.
- Warm the sauce gently before spooning it over grilled lamb, pork, or chicken to intensify its aroma.
- Make it a day ahead; the flavor becomes deeper and more balanced overnight.
- Reserve a portion before marinating meat so you have a clean finishing sauce ready to drizzle over the finished dish.
How To Grill Butterflied Lamb Leg
Make Marinade
Place marinade ingredients in a blender and pulse until mix is roughly blended.
Alternatively and preferred - make a paste with the garlic, salt, and oregano by grinding using a mortar and pestle.
Place paste in a bowl. Add the lime and orange juices plus the ground cumin and mix well.
Place lamb in a large ziplock bag. Add the marinade. Remove as much air out of the bag as possible then seal and refrigerate 4 hours or preferably overnight.
Grill Lamb
Pre-heat grill for direct cooking over high heat.
Remove lamb from the refrigerator. Remove lamb from the marinade mixture and allow to reach room temperature. Pat dry the lamb.
Place the lamb directly over the heat and grill 6-10 minutes per side (lid closed) depending on temperature and thickness of the lamb. Allow for more cooking time the thicker the lamb. I like medium rare for this which is an internal temperature of about 130 degrees F if you're using a meat thermometer which I recommend.
Remove from the grill. Cover lightly with aluminum foil and allow to cool for five minutes or so. I serve this with the reserved marinade that I reduce in a saucepan. Alternatively you can add a little lemon zest or lemon juice crushed red pepper flakes.
Recipe Notes for Cooks
- Ask your butcher to butterfly the leg of lamb if you don't want to do it yourself.
- Marinate at least 4 hours, but overnight delivers noticeably deeper flavor.
- Pat the lamb dry before grilling to maximize browning.
- Grill with both direct and indirect heat zones to prevent flare-ups from the lamb fat.
- Cook to 130 to 135°F for medium rare and let carryover cooking finish the job.
- Slice against the grain for the most tender texture.
- Reserve fresh marinade separately if you plan to reduce it into a serving sauce. Never reuse marinade that touched raw meat unless it is thoroughly boiled.
- Leftovers make excellent sandwiches, grain bowls, tacos, or salads the next day.
