Main Ingredients: Proper Portions, Like Grandma Used To Make
Lamb: 1 (5-6 pound / 2.2-2.7 kg) leg of lamb , bone-in. Now, quality is key here. Look for lamb that's a nice pinkish red colour with creamy white fat.
Not too yellow, that means it's old. I usually get mine from the butcher, they give me the best cuts, honestly.
Olive Oil: 2 tablespoons (30ml). Go for extra virgin; it makes a difference.
Garlic: 4 cloves , minced (approx. 12g). Fresh is best, always.
Rosemary: 2 tablespoons fresh, chopped (approx. 6g). That fragrant rosemary is what elevates all lamb roast recipes !
Dijon Mustard: 1 tablespoon (approx. 14g).
Sea Salt: 1 teaspoon (approx. 5g).
Black Pepper: 1/2 teaspoon (approx. 2.5g).
Veggies: 1 large onion (quartered, approx. 200g), 2 carrots (roughly chopped, approx. 150g), 2 celery stalks (roughly chopped, approx. 100g). This is essential. These babies make delicious gravy!
Broth: 1 cup chicken or vegetable (240ml). If you don't have any, water with a bouillon cube will do in a pinch.
Flour: 2 tablespoons all-purpose (16g, optional, for gravy). This is for thickening the gravy, if you’re into that sort of thing.
Spice Up Your Life: Seasoning Notes
For this Easy Lamb Roast Recipe , we're sticking to classics. Rosemary and garlic are a match made in heaven for lamb.
The Dijon mustard just adds a little something extra. Feel free to add a pinch of red pepper flakes if you like a bit of heat.
Some people also like thyme. You know? It's totally up to you. Don't be afraid to experiment and find your ideal lamb roast dinner experience.
Essential Kit: You Don't Need the Whole Shop
- Roasting Pan with Rack: Absolutely crucial for even cooking.
- Small Bowl: For mixing the herb paste.
- Sharp Knife: For scoring the lamb.
- Meat Thermometer: Honestly, you need one. Insert the thermometer into the thickest part of the lamb, avoiding the bone, and aim for 130° F ( 54° C) for rare.
- Aluminum Foil: For tenting the lamb while it rests.
Now, don't stress if you don't have everything. A baking tray can work instead of a roasting pan, although it won’t be as even.
I hope this gets you started on a grand oven-roasted Lamb Shoulder .

Serving Suggestions - Making it Look the Business
Presentation is key, isn't it? A perfectly Garlic Rosemary Lamb Roast deserves to be shown off. Slice the lamb nice and thick and arrange it on a platter.
Drizzle with the gravy, obviously. A sprig of fresh rosemary just makes it look a bit fancy.
For sides, classic roast potatoes are a must. Yorkshire puddings? Absolutely! And a simple green veg like green beans or asparagus cuts through the richness.
Don't forget a cracking red wine. It's just perfect.
Storage Tips - Keeping it for Later
If you're lucky enough to have leftovers (which rarely happens in my house!), you can pop them in the fridge for up to three days.
Make sure the lamb is in an airtight container though, yeah?
Freezing is an option too. Slice the lamb first and freeze it in portions. When you want to reheat it, let it thaw completely and then warm it up in the oven with a little bit of gravy to stop it drying out.
Aim for a temperature of 165° F ( 74° C) to ensure it's safe to eat.
Variations - Switching Things Up
Fancy a change? Instead of rosemary and garlic, try thyme and lemon zest. It gives it a lovely, bright flavour.
Or, if you're feeling adventurous, add a pinch of red pepper flakes to the herb paste for a bit of a kick.
For dietary swaps, use sweet potatoes.

Frequently Asked Questions
What's the best internal temperature for a roast of lamb recipes, and how do I use a meat thermometer?
For a perfectly cooked roast of lamb, use a meat thermometer! Insert it into the thickest part of the lamb, avoiding the bone. For medium rare, aim for 135°F (57°C); for medium, 140°F (60°C); and for well done, 160°F (71°C).
Remember that the temperature will continue to rise slightly as the lamb rests, so pull it out of the oven a few degrees before your target temperature.
Can I marinate the lamb overnight? Is it worth the effort?
Absolutely, marinating the lamb overnight is a brilliant idea! A longer marinating time allows the flavours of the rosemary, garlic, and Dijon mustard to deeply penetrate the meat, resulting in a more flavourful and tender roast. Just make sure to keep it covered in the fridge.
Think of it as giving your lamb a proper spa day before the big roast!
My roast lamb is tough! What am I doing wrong?
Tough lamb is a common issue, but easily solved! Overcooking is the usual suspect. Always use a meat thermometer and avoid cooking past your desired doneness. Crucially, let the lamb rest for at least 15-20 minutes after roasting, tented with foil.
This allows the juices to redistribute, making it more tender and juicy. Carving against the grain also makes a difference!
I don't have rosemary. Can I use dried rosemary for this roast of lamb recipe, or substitute it?
While fresh rosemary is best, you can certainly use dried rosemary in a pinch. As a general rule, use about 1 teaspoon of dried rosemary for every tablespoon of fresh. Alternatively, fresh thyme makes a great substitute. Both herbs will add an earthy, aromatic flavour to your roast.
Don't be afraid to experiment with other herbs as well a little oregano or marjoram can also be lovely!
How do I make gravy from the pan drippings? What if I don't have broth?
Making gravy is easier than you think! After removing the lamb, place the roasting pan on the stovetop. Sprinkle in some flour, cook for a minute, then gradually whisk in broth, scraping up those delicious browned bits. If you don't have broth, water with a bouillon cube works well.
Simmer until thickened, then strain for a smooth gravy. It's proper "lick the-plate" good!
What are some good side dishes to serve with roast lamb?
Roast lamb is a classic, so it calls for classic sides! Roasted potatoes are a must, soaking up all those lovely pan drippings. Yorkshire puddings are another great choice for gravy sopping. For a bit of freshness, serve with steamed green beans, asparagus, or a mint sauce.
And don't forget a full bodied red wine to complete the meal cheers!
