The Easiest Way to Cook a Roast Leg of Lamb This Easter

If you’ve been anywhere near a supermarket this week, you’ll have noticed the same thing—cracking deals on leg of lamb everywhere you look. Easter has a way of bringing lamb front and centre, and retailers know it. From half-price offers to multi-buy deals, it’s one of the best times of year to pick one up.

But here’s your gentle reminder: if you haven’t grabbed one yet, you’ll need to be quick. Most major supermarkets close on Easter Sunday, so today is your last chance to get your hands on one before the big day.

The good news? Once you’ve got it, cooking it couldn’t be easier.

Why Lamb Is the Perfect Easter Centrepiece

There’s something about a roast leg of lamb that just feels right at Easter. It’s rich, comforting, and just a little bit special—without being overcomplicated. Paired with garlic and rosemary, it delivers that unmistakable flavour that instantly makes your kitchen smell like a proper Sunday roast is underway.

And despite what you might think, it’s actually one of the most forgiving cuts of meat to cook.

The Easiest Way to Roast Leg of Lamb

This is not a recipe that requires constant checking, complicated steps, or cheffy techniques. It’s simple, reliable, and gives you consistently great results every time.

What You’ll Need

1.5–2kg leg of lamb
4–6 garlic cloves, sliced
Fresh rosemary
Olive oil
Salt and black pepper
Optional: a squeeze of lemon

Step 1: Let It Come to Room Temperature

Take your lamb out of the fridge about 30–60 minutes before cooking. This helps it cook evenly and keeps it tender.

Step 2: Keep the Prep Simple

Using a sharp knife, make small slits all over the lamb. Push slices of garlic and sprigs of rosemary into each one.

Drizzle with olive oil, season generously with salt and pepper, and that’s it. No marinades, no fuss.

Step 3: Into the Oven

Preheat your oven to 180°C (160°C fan).

Place the lamb in a roasting tray and cook for:

20 minutes per 500g for a perfectly pink, medium finish
Add an extra 10–15 minutes if you prefer it more well done

For a typical 2kg leg, you’re looking at around 1 hour 20 minutes.

Once it’s in, you can largely leave it alone—no need for constant basting or turning.

Step 4: Let It Rest

When the lamb is done, take it out and cover loosely with foil. Let it rest for 15–20 minutes before carving.

This step makes all the difference—it keeps the meat juicy and tender.

Why This Method Works Every Time

It relies on simple flavours that always work
It’s low effort, ideal if you’re hosting
It gives you a crisp exterior and tender centre
And most importantly, it lets the lamb shine

What to Serve Alongside

Keep it classic:

Crispy roast potatoes or try our Pommes Boulangère Recipe
Carrots or parsnips
Greens like broccoli or cabbage
Mint sauce or gravy

Or lighten things up with new potatoes and a fresh spring salad.

A Roast Worth the Occasion

Easter Sunday doesn’t need to be stressful in the kitchen. With a good piece of lamb and a straightforward approach, you can create something that feels special without overthinking it.

So if you’ve managed to grab a bargain leg of lamb this weekend, you’re already halfway there. The rest is just a hot oven, a bit of patience, and the promise of a proper roast dinner waiting at the end of it.
