Choosing the Right Leg of Lamb for Your Roast
Your roast’s success starts before it even hits the oven.
While any lamb can be roasted, grass‑fed lamb delivers superior results.
Why choose grass‑fed lamb?
Grass‑fed lamb from Gingin Grassfed delivers:
- Natural, robust flavour
- Lean but juicy meat texture
- Ethical and sustainable farming practices
- Less fatty drippings that still taste rich
Because the lamb grazes on nutrient‑rich pasture, you’ll notice the depth of flavour right from the first bite.

Preparing Your Lamb for Roasting
Before we talk cooking times, you need to prep your lamb.
Step‑by‑Step Prep:
- Bring the lamb to room temperature
Pull your lamb out of the fridge 30–45 minutes before roasting.
This ensures even cooking. - Trim excess fat
A thin layer is great for flavour, but large fat deposits can cause flare‑ups. - Score and season
Lightly score the surface, especially where you’ll insert garlic.- Rub with olive oil
- Sprinkle sea salt and black pepper
- Add herbs (rosemary, thyme)
- Insert garlic slivers
Make small cuts and push garlic cloves into the meat.
Now you’re ready to roast!

Oven Setup
Set your oven to 180°C fan‑forced (or 200°C conventional).
Place the lamb on a roasting rack so heat circulates evenly. If you don’t have a rack, a bed of roughly chopped onions and carrots works too.
Cooking Process
- Roast uncovered for first 20 minutes.
This helps brown the exterior. - Lower heat to 160–170°C and continue roasting.
Refer to the timing chart above. - Baste occasionally with pan juices.
This improves flavour and stops drying. - When done, remove from oven and rest for at least 15 minutes.
Resting lets the juices redistribute and gives you tender meat.
Best Side Dishes for Roast Leg of Lamb
Your lamb deserves sides that match its flavour. Consider:
Classic Complements:
- Roasted rosemary potatoes
Crisp on the outside, fluffy inside. - Garlic & rosemary carrots
Sweetness meets savoury. - Mint sauce or jelly
A traditional favourite with lamb. - Green beans with almonds
For freshness and crunch.
Herb and Seasoning Options
Garlic is the star, but a few herbs can take your roast to the next level.
Try combining:
- Rosemary: Pungent and piney
- Thyme: Subtle earthiness
- Oregano: Mediterranean flair
- Lemon zest: Bright contrast to rich lamb fat
Rub these with olive oil on the lamb before roasting.
How to Carve Your Roast Leg of Lamb
Once rested, carving correctly makes a difference.
- Cut against the grain (this makes each slice tender).
- Use a sharp carving knife.
- Scoop up pan juices and drizzle over meat slices.
This makes serving easier and enhances flavour at the table.
Common Mistakes to Avoid
Even seasoned cooks slip up. Here’s what to watch for:
Overcooking
Dry, stringy lamb means you missed the right internal temperature.
Not Resting
Cutting too soon lets all those tasty juices escape.
Skipping Seasoning
Lamb loves salt, pepper and herbs. Don’t hold back!
Tips for Next‑Level Flavour
Want to go beyond the basics? Try these:
Marinade the lamb overnight
Infuse garlic, lemon zest, rosemary and olive oil for up to 12 hours.
Use rock salt crust
This insulates the lamb, keeping it moist and tender.
