Roast lamb leg with gravy
Roast lamb leg with gravy sits in our dinner collection for weeknight dinners when you still want something proper. We keep the voice practical — what to buy, what heat to use, and how to tell when it is done. As written it serves 6–8. Budget about 5 min to prep and 1 hr 40 min to cook or bake, roughly About 3 hr (includes 1 hr out of fridge and 20 min rest) all up, across 10 ingredients and 6 method steps. Key building blocks: bone-in lamb leg, cooking salt and ½ tsp black pepper. If you need a substitute, change one thing at a time and expect the texture notes below to matter more than the timer. After cooking, serve straight from the pan with a simple salad or mash. Feeds a small table as written; bump quantities if you are feeding a crew. If humidity or a fan oven changes browning, trust visual cues over the last minute of the clock. Method opens with: “Take lamb out of the fridge at least 1 hour before roasting. Heat oven to 240°C (220°C fan).”. Follow the order as written; jumping ahead is how pans crowd and sauces split.
Ingredients
Method
- Take lamb out of the fridge at least 1 hour before roasting. Heat oven to 240°C (220°C fan).
- Mix rosemary, minced garlic and oil. Rub all over the lamb, then sprinkle salt and pepper. Sit lamb on the cut garlic heads and rosemary sprigs in a roasting pan.
- Roast 20 minutes. Drop oven to 200°C (180°C fan) and roast about 1 hour more, until internal temperature is 53°C for medium-rare. Check from 45 minutes.
- Rest 20 minutes loosely foil-covered (temp will rise to about 62°C).
- Gravy: put pan on medium heat with about 4–5 tbsp drippings. Stir in flour 1 minute. Whisk in stock in two lots. Mash the roasted garlic into the gravy. Simmer until it starts to thicken, then strain.
- Carve and serve with gravy, roast potatoes, peas and buttered carrots.
Tip: Use a thermometer — lamb leg is lean and dries if it goes past pink. Take it out at 53°C, not 62°C, because of carry-over heat. Beef stock makes a darker, better gravy than chicken.
Notes
- Shopping and mise en place: read the full ingredient list once before you start. For Roast lamb leg with gravy, bone-in lamb leg and cooking salt are the items that decide whether the dish tastes flat or properly seasoned. Weigh where grams are given — volume cups are fine for liquids and some dry goods, but baking ratios are tighter if you use scales. Australian cups are 250 ml; a tablespoon is 20 ml and a teaspoon is 5 ml.
- From our tested tip, expanded: Use a thermometer — lamb leg is lean and dries if it goes past pink. Take it out at 53°C, not 62°C, because of carry-over heat. Beef stock makes a darker, better gravy than chicken. Treat that as the non-negotiable. If something still feels off — too wet, too pale, too tight — adjust one variable at a time (heat, liquid, or bake time) rather than changing three things at once.
- Make-ahead and leftovers: feeds a small table as written; bump quantities if you are feeding a crew. Leftovers of Roast lamb leg with gravy usually keep 2–3 days in a sealed fridge container; reheat until steaming hot in the centre. Label freezer bags with the dish name and date. Allergens sit in the ingredient list — always double-check if cooking for guests.

Keep this page bookmarked if it becomes a household regular — we update wording when cooks report a confusing step. Metric consistency across Scoops & Dishes means once you trust the cups and scales here, breakfast through dessert behaves the same way.
