Chimichurri barbecued lamb is the kind of grilled lamb recipe that turns an ordinary barbecue into something seriously special, with juicy, smoky meat covered in a bright homemade chimichurri sauce. The combination is fantastic: rich lamb gets kissed by the heat of the grill while parsley, garlic, herbs, vinegar and olive oil bring a fresh, punchy contrast to every bite.
There is something wonderfully celebratory about serving lamb at a summer gathering. Lamb has long been enjoyed across Mediterranean, Middle Eastern and South American cooking traditions, while chimichurri is particularly associated with Argentine and Uruguayan cuisine, where the vibrant herb sauce is a classic partner for grilled meats.
Put the two together and you have a seriously impressive barbecue dish without needing complicated cooking techniques.
I especially love this BBQ lamb recipe for entertaining because most of the work can be done before everyone arrives. Prepare the chimichurri ahead, season the lamb, fire up the barbecue and let the grill create those gorgeous caramelised edges. It is ideal for Father’s Day recipes, summer dinner ideas, holiday entertaining or a relaxed family barbecue.
And honestly, the homemade chimichurri is the secret weapon. It is fresh, garlicky, slightly sharp and wonderfully herby, cutting through the richness of the lamb and making every mouthful feel lighter and more exciting.
Why You’ll Love This Chimichurri Lamb Recipe
This isn’t complicated barbecue cooking. It is all about getting a few simple elements right.
The lamb should be generously seasoned so that the natural flavour of the meat really shines. Grilling over high heat creates a beautifully browned exterior, while allowing the meat to rest keeps the centre juicy.
Then comes the chimichurri.
Fresh parsley, garlic, oregano, red wine vinegar and extra-virgin olive oil create a sauce that is incredibly aromatic and vibrant. A little chilli gives it a gentle kick without overpowering the lamb.
For this grilled lamb recipe, I recommend using lamb leg steaks, butterflied lamb leg or lamb loin chops. A butterflied leg is particularly fantastic when you’re feeding a crowd because it grills beautifully and can be sliced before serving.

How to Make Chimichurri Barbecued Lamb
Start by preparing the lamb.
Place the lamb in a large dish and drizzle over the olive oil. Add the minced garlic, oregano, smoked paprika, salt, pepper and lemon juice. Rub everything thoroughly into the meat, making sure the seasoning reaches all the little folds and edges.
Leave the lamb at room temperature for around 30 minutes before grilling. This takes the chill off the meat and gives the seasoning a little time to work.
While the lamb rests, make the chimichurri.
Add the parsley, coriander, garlic, oregano and chilli to a bowl. Stir through the red wine vinegar, then gradually add the olive oil. Season with salt and black pepper and mix well.
Taste it.
This is important because chimichurri is incredibly easy to adjust. Want more zing? Add another splash of vinegar or lemon juice. Prefer more heat? Add extra chilli. Like a softer, rounder sauce? Add another drizzle of olive oil.
Set the sauce aside for at least 15 minutes before serving so the flavours have time to mingle.
Now get your barbecue properly hot.
Place the seasoned lamb onto the grill and cook over direct heat until beautifully browned and lightly charred. Depending on the thickness of your lamb, this can take roughly 6–10 minutes per side.
For thicker cuts, move the lamb to a cooler part of the barbecue after searing and continue cooking until it reaches your preferred doneness.
Use a meat thermometer rather than relying entirely on appearance. Lamb is best when it remains tender and juicy, so avoid overcooking it.
Once cooked, transfer the lamb to a board and let it rest for around 10 minutes.
This step is absolutely worth it.
Resting allows the juices to redistribute through the meat instead of immediately running onto your chopping board. After resting, slice the lamb against the grain and spoon plenty of homemade chimichurri over the top.
Serve immediately.
What Does Chimichurri Taste Like?
If you’ve never made chimichurri before, prepare to become slightly obsessed.
Traditional-style chimichurri has a fresh, herbaceous flavour with garlic, acidity and olive oil working together. The red wine vinegar gives the sauce its characteristic tang, while chilli adds a little heat.
That acidity is particularly brilliant with lamb.
Because lamb has a naturally rich flavour, the sharpness of chimichurri balances it beautifully. Instead of making the meal feel heavy, the sauce adds freshness and brightness.
It’s also incredibly versatile. Once you’ve made a batch, don’t stop at lamb. Try it with grilled chicken, steak, roasted vegetables, potatoes or crusty bread.
My Pro Tips for Perfect Barbecued Lamb
1. Don’t rush the resting time.
Give the lamb around 30 minutes at room temperature before grilling and another 10 minutes after cooking. Those little pauses can make a surprisingly big difference to the finished texture.
2. Get the barbecue properly hot.
You want enough heat to create those delicious browned, slightly charred edges. A lukewarm grill won’t give you the same flavour or texture.
3. Make the chimichurri ahead.
Although you can serve it immediately, letting it sit for 15–30 minutes gives the garlic, herbs, vinegar and chilli time to mingle.
4. Don’t drown the lamb in sauce.
Chimichurri is powerful stuff. Spoon some over the sliced lamb and serve the rest alongside so everyone can add as much as they like.
5. Slice against the grain.
This simple technique helps make each piece of lamb more tender and enjoyable, especially when you’re working with a larger cut such as butterflied lamb leg.
What to Serve With Chimichurri Lamb
This is one of those summer dinner ideas where the sides can be wonderfully simple.
For a classic barbecue spread, serve the lamb with crispy roasted potatoes, grilled corn, a fresh tomato salad and a bowl of leafy greens.
Grilled vegetables are another fantastic option. Courgettes, peppers, aubergines and asparagus all work beautifully with the smoky lamb and sharp herb sauce.
For something a little more Mediterranean-inspired, add warm flatbreads, hummus, cucumber salad and roasted vegetables.
And if you’re putting together a larger family barbecue, make extra chimichurri. Seriously. People will start putting it on everything.
Frequently Asked Questions
What cut of lamb is best for barbecuing?
Butterflied lamb leg is an excellent choice because it has plenty of flavour and is easy to cook over a barbecue. Lamb chops and lamb loin are also fantastic for quicker individual portions.
Can I make chimichurri ahead of time?
Absolutely. In fact, preparing it ahead is a great idea. Store it covered in the refrigerator and bring it closer to room temperature before serving so the olive oil loosens and the flavours are easier to appreciate.
How long should lamb rest after grilling?
Around 10 minutes is a good starting point for a larger cut. Smaller lamb chops need less resting time.
Can I make this recipe without a barbecue?
Yes. A cast-iron grill pan or heavy frying pan can give you excellent results indoors. Make sure your kitchen is well ventilated because the high heat can create plenty of smoke.
The Best Way to Serve It
For me, the magic happens when the lamb is sliced into generous pieces, piled onto a large serving platter and finished with spoonfuls of bright green chimichurri.
Don’t be shy with the sauce.
Let a little run over the edges of the meat and onto the serving platter. Put the remaining chimichurri in a bowl alongside the lamb and surround everything with colourful grilled vegetables, potatoes or salad.
It looks impressive, but the preparation is wonderfully uncomplicated—which is exactly what I want from a good BBQ recipe.
The smoky lamb, fresh herbs, garlic, chilli and vinegar create a combination that feels restaurant-worthy while still being completely achievable in your own garden.
Final Thoughts
This chimichurri barbecued lamb is proof that an impressive summer meal doesn’t need a huge ingredient list or hours in the kitchen. A well-seasoned piece of lamb, a hot barbecue and a bowl of vibrant homemade chimichurri are really all you need.

Whether you’re planning Father’s Day recipes, a summer gathering, a special holiday meal or simply want to upgrade your next weekend barbecue, this is a recipe I’d happily put at the centre of the table.
And once that first slice of lamb hits the plate with a generous spoonful of chimichurri on top, don’t be surprised if everyone suddenly starts asking when you’re making it again.
