It's always good to have some tender meat ready for making low-carb meals. Once cooked, you can keep it in the fridge and use straight away.
Slow-cooked lamb is great when served on top of fresh crunchy lettuce (6.1 g net carbs), omelet (3.4 g net carbs) or sweet pepper (7 g net carbs). So versatile!

Step-by-step
Preheat the oven to 150 °C/ 300 °F (fan assisted), or 170 °C/ 340 °F (conventional). Peel the garlic and slice it into smaller pieces. Black garlic is aged white garlic and you can find it in most large grocery stores. It's sweet and has similar taste like balsamic vinegar. If you can't find black garlic, use freshly sliced white garlic.

Place the lamb leg into a baking dish. Add balsamic vinegar, fruit vinegar, sliced garlic and rosemary. Season with salt and add water. Cover with a lid and place the lamb in the oven for about 2 hours. The timing is simple. You should add at least 30 minutes for every 500 g/ 1.1 lb/ of lamb leg.

After 2 hours, take the lid off, baste with the vinegar juices, and increase the temperature to 200 °C/ 400 °F (fan assisted), or 220 °C/ 425 °F (conventional). Cook for another 30-45 minutes, basting with the juicesone or twice again.

When done, carefully remove from the oven and let it cool down for a few minutes. When the meat is still warm, shred it with a fork. Pour the meat sauce over the shredded meat. Place it back in the oven if it needs reheating.

Separate the lettuce leaves. Wash and place them into a salad spinner or simply tap off the excess water using a paper towel. Top with the shredded meat mixture. The cooked meat can be stored in the fridge for up to 4 days.

Hi. Where i'm from lamb isn't that usuaal. What kind of meat cuts from beef or pork, can I use instead? Sorry for bad english.
Hi Johan, no need to apologise, your English is absolutely fine! If you use beef, I'd use oxtail, brisket, silverside, neck, middle ribs or leg. If you use pork, try belly, chump end, spare rib and hand. I also have a recipe for slow-cooked oxtail on my blog (oxtail is my absolute favourite cut of beef). Have a look here in the "meat" category: Meat Recipes
Awesome, I love your blog! Thank you for this recipe. I'll go and get some lamb now 😊
Thank you for your kind words Mary 😊
