Lamb can be a tricky meat to get right. You need to know how to work with the different cuts.

Some cuts that are leaner like backstrap are best suited for grilling. Then you have the lamb shoulder which is a fattier cut with a lot of connective tissue that lends well to low and slow style cooking.

In this recipe, I’ll be going through a few techniques to help you get a more succulent finished lamb blackstrap. I’ll also show you an easy roast Zucchini salad that will go perfectly.

Grilled Lamb Backstrap

Lamb backstrap is cut from near the spine in the middle of the loin. The backstrap is the same cut you call a ribeye that comes from beef.

The fact is the average lamb weighs 135 lbs and the average cow weighs 1,100 lbs at slaughter. So being a smaller leaner cut of meat, it tends to cook quickly, so it’s not one to walk away from the grill while cooking.

It’s a premium, lean cut and has a slightly milder flavor, making it a perfect choice for anyone that’s still on the fence about eating lamb.

Have I said to you that you need to have a good relationship with your local butcher before? I know I bang on about this but it truly does make a difference in how much they will go out of their way to help you. 

You’ll need to get some decent sized lamb backstrap. Remembering this is lamb, so they won’t be huge but two decent sized ones should easily feed four people.

I feel a lot of people stay away from eating lamb mainly because their only experience in eating it was eating older mutton or eating overcooked lamb, which tends to be hard and chewy. By following this recipe and cooking method, you’ll always be eating succulent juicy lamb and loving it.

Items that will help you cook these are:

Stuffing the lamb backstrap

If you cannot find fresh spinach, don’t worry, most supermarkets now stock it frozen. Hence I had to use it for this recipe.

So defrost the spinach and roughly chop it up, then squeeze out as much moisture as possible. Now combine the spinach, feta and garlic into a bowl and mix thoroughly, then put aside.

Using a sharp knife, cut a pocket into the side of each backstrap, from one end to the other. Making sure not to cut right through, we need to be able to keep the spinach mixture in as we cook the backstraps.

Now using the spinach mixture, fill up each backstrap with plenty of mixture. Don’t be shy, get a lot into each one.

Now using butcher’s twine or cooking string, tie each backstrap up. I usually use 5 to 6 pieces depending on the size of the backstrap. Make sure they are nice and tight and the seam is pretty much closed up.

Now onto the seasoning. Just give each backstrap a light coating of oil, just to help the rub to stick. 

Now combine all of the lamb rub ingredients into a bowl and mix thoroughly. I tend to transfer dry rubs to a rub shaker; this just helps applying it evenly.

Apply from a height of around 12” to make sure you get even coverage and no clumping of the ingredients on the lamb.

Place the lamb backstraps aside while you prep the BBQ, this just to allow the herbs to start flavoring the meat.

High heat set up perfect for roasting

For this cook we need a high heat source up around the 400°F range; not only to get some good color on the lamb but also to roast the vegetables we’ll be serving with the lamb.

I’m using a 22” Weber Kettle, so I’ll start off by lighting up a chimney of charcoal briquettes.

Once the briquettes are all fully lit, I’ll dump them into two charcoal baskets and position them on either side of the charcoal grate. I tend to wear heat proof gloves and use an old pair of grill tongs when doing this.

I’ll place the lid back on, making sure all the vents are open and allow the grill to warm up for 10 minutes.

Once the Weber is up near the 400°F temp, I’ll give the grill a brush with a wire brush and then place the stuffed lamb backstraps on the cooking grate between the charcoal baskets.

I’ll put the lid back on and just keep a check on the internal temp of the lamb. Most people have a tendency to overcook lamb, which results in a chewy feed. We are only wanting to take the internal temp to 135°F and then allowing a 30-minute rest under some foil. 

Lamb really likes a good long rest. Trust me, it will make for a more tender bite.

Roasted Zucchini Salad

If I have to eat salads to be healthy, then this recipe is on the top of my list.

I tend to get the vegetables prepared before I cook the lamb. It just makes for an easier cook and I like to be prepared.

To do this, start off by trimming the ends of the zucchinis and cutting them into thick ½” slices. Then deseed the bell peppers and cut them into ½” strips. Now peel and cut the onions into ½” wedges.

Put all the prepped vegetables into a baking dish along with the cherry tomatoes and drizzle with olive oil and then sprinkle the paprika, mint and salt and pepper and mix up thoroughly.

Then this can get into the Weber set up for roasting at 400°F for 30 minutes. Turning them once during the cooking process.

You’ll know when the vegetables are done, as the tomatoes will start to soften and break down a little.

That’s when it’s time to take them off the heat and allow the vegetables to cool for a couple of minutes. 

Vinaigrette recipe

I love adding a nice, fresh vinaigrette to my salads and this roasted salad is no exception. This recipe suits both the roasted vegetables and the lamb really well and it’s super easy to make.

Into a small bowl, add the shallots, vinegar, mustard, honey and garlic. Whisk this up and then slowly add the oil while whisking.

Once all of the oil is added and thoroughly mixed, season with salt and pepper. 

You won’t need a lot of this; it’s just a nice fresh flavor that helps combine all the others together.

Serving suggestions

First things first, we need to remove the string from the lamb backstrap, although we are meant to use dental floss after each meal, having it with the meal is not a good look. So grab a pair of scissors and remove it now.

The flavors of the roasted vegetables and the spinach and feta stuffed lamb backstrap really blend well together. So I tend to make a bed of the roasted vegetables on a plate. I then like to top this with some thickly cut ¾” pieces of the stuffed lamb backstrap.

I’m a sauce guy. I love to accompany most dishes I make with one, so this one is no different but being lamb and roasted vegetables, I wanted to have a fresh and tasty vinaigrette that wasn’t going to overpower the delicate flavors we already have on the plate.

So just add a drizzle of the vinaigrette. A little goes a long way and you can refrigerate the rest for a few weeks.

This is the sort of meal that can be enjoyed with a glass of wine or nice pale ale or six if you’re at my place.
