What ingredients are in Barbecue Garlic Rack of Lamb?

For this BBQ Garlic Rack of Lamb, you’ll need just a handful of quality ingredients, which makes this recipe absolutely brilliant for both special occasions and weekend meals.

The star of the show is obviously the lamb itself, which develops the most gorgeous flavour when cooked over the barbecue. I’m rather particular about keeping things simple with lamb, as the meat has such a wonderful natural taste that doesn’t need much fussing about.

• 2 racks of lamb (frenched, with fatty skin removed if desired)
• 1-2 tablespoons oil
• 2 tablespoons minced garlic (or roasted garlic bulbs, mashed, for a sweeter flavour)
• Freshly ground mix of coloured peppercorns (pink, green & black)
• Salt

When shopping for your ingredients, do try to source the highest quality lamb you can find. A good butcher will french the rack for you (that’s the process of cleaning the rib bones), though many supermarkets now sell them ready prepared.

And regarding the garlic, might I suggest the roasted option if you have the time? It creates the most heavenly sweet flavour that complements the lamb beautifully.

While the recipe is charmingly simple, the quality of these few ingredients will make all the difference to your finished dish.

How to Make this Barbecue Garlic Rack of Lamb

For a truly spectacular BBQ Garlic Rack of Lamb, I recommend using the indirect cooking method on your barbecue. Start by preheating your BBQ to about 180°C (which is equivalent to 350°F mentioned in the original recipe).

While that’s warming up, take your 2 racks of lamb and prepare them for their smoky journey. Heat 1-2 tablespoons of oil in a cast iron pan directly on the barbecue grill and sear those lovely racks on all sides, beginning with the meaty side first to develop a gorgeous crust. This initial searing locks in all those magnificent juices and creates a depth of flavour that’s simply divine. Using a Monolith cast iron grid can enhance your searing experience by providing excellent heat conduction.

Once your lamb racks are beautifully seared, remove them from the heat and generously spread 2 tablespoons of minced garlic all over the meat. Now, if you’ve got the time, might I suggest using roasted garlic bulbs that have been mashed instead? They lend a sweeter, more mellow flavour that pairs wonderfully with the smoky notes from the barbecue.

Next, sprinkle your lamb with a freshly ground mix of coloured peppercorns and a good pinch of salt. Then move the racks to the indirect heat zone of your barbecue, this is where the magic happens. Close the lid and let them roast for about 20-30 minutes, depending on how you prefer your lamb cooked.

The beauty of cooking this rack of lamb on the barbecue is the subtle smokiness that infuses the meat. When your lamb has reached your desired doneness (perhaps 60°C internally for medium-rare or 65°C for medium), remove it from the barbecue and allow it to rest.

This resting stage is absolutely essential, so either cover it loosely with foil or, if your barbecue has cooled slightly, leave it in there with the heat off for about 5 minutes. The resting period allows the juices to redistribute throughout the meat, ensuring each slice is magnificently succulent.

When ready to serve, you can either slice between the bones or present the rack whole for a more dramatic presentation at the table. Either way, the combination of garlic, pepper, and that distinctive barbecue flavour will make this a memorable meal indeed.

Frequently Asked Questions

How Long Should I Let the Lamb Marinate Before Cooking?

As hungry as a wolf, I don’t see marinade time mentioned in the recipe. I’d suggest at least 2 hours for flavour infusion, though overnight would deepen the garlic-pepper profile.

What’s the Ideal Internal Temperature for Medium-Rare Lamb?

For medium-rare lamb cooking, I aim for an internal temperature of 57°C (135°F). I recommend using a meat thermometer to check for doneness, then resting your lamb before slicing.

Can I prepare the racks a day in advance?

Like a fine wine ageing beautifully, I’ve found prepping lamb racks a day ahead enhances flavour. Yes, you can prepare them—actually, marinating tips suggest overnight refrigeration allows garlic and pepper to deeply infuse the meat.

How many people does one rack typically serve?

I would say one rack typically serves 2-3 people, depending on appetites and other dishes you’re serving. When planning cooking portions, I consider serving sizes of about 2-3 chops per person.

Should I cover the exposed bones with foil while cooking?

I don’t typically cover lamb bones with foil while cooking. They’ll naturally brown nicely, adding to the presentation. If you’re concerned about charring, you can wrap just the exposed tips.
