Keto roast lamb with rosemary recipe

Keto roast lamb with rosemary recipe

A Sunday roast dinner is a wonderful treat and a great way to end a busy week. I always try and make time for one, and my friends and family are huge fans of this recipe, which is packed with flavour. The best thing about a roast dinner is that it doesn’t call for any carbs – the flavour of the meat and vegetables more than makeup for its absence.

I won’t lie to you – at first, it wasn’t easy to forgo the traditional roast potatoes that are usually found accompanying a roast lamb dinner, but the flavour of this lamb makes up for it.

When picking your meat, I strongly recommend buying organic, grass-fed lamb, as it has so much more nutrients and health benefits. It’s also significantly higher in omega-3 fatty acids, which is essential for a healthy heart.

For this recipe, I used a leg of lamb. I always ask my butcher to loosen the bone before putting it back in. This is crucial because the bone emits loads of flavour when cooking and is packed with nutrients that you don’t want to lose, and by loosening it up a little, I can pull it out before I start carving.

Timing is also important – leave your roast lamb in the oven for too long, and it will dry out and become tough and rubbery. As a general rule, you should cook it for 10 minutes per pound of lamb for a medium-rare roast. And don’t forget the resting time – this is crucial! Leave the roast covered in a baking tin to rest for an additional 20 minutes. This pulls in the heat and helps the juices of the meat keep the lamb moist and soft.

Finally, I use carrots and tomatoes to accompany my roast lamb, but you can swap it for other vegetables, just as long as they are relatively low in carbs.

Featured ingredient: Lamb

Red meat, including lamb, has a lot of stigmas attached to it. There are so many scare stories about how consuming red meat can lead to heart attack, high cholesterol, and weight gain. But, if you follow the keto diet, you will know that red meat is perfectly fine to eat without getting sick or putting on loads of weight.

In reality, lamb is a fantastic source of protein, and if eaten in moderation, it can have some great health benefits. It’s full of vital nutrients like zinc and iron and essential B vitamins, including B6, B3, B2, and B12. This type of vitamin helps promote a healthy nervous system function. This is an essential part of our health as the nervous system ultimately controls how the entire body communicates and functions as one entity.

Consuming lamb can also help boost our immune system as it’s packed with zinc. A healthy immune system will help you fight off colds and illnesses much quicker, as well as make you less susceptible to infections like pneumonia. It can also help promote healthy growth and development, making it an ideal meal for children.

Lamb is also loaded with iron, more so than other protein sources like chicken or fish.

Some people will argue that lamb can make you put on weight rather than lose it. Yes, lamb does contain fat, but most of this fat is omega-3 fatty acids, which are actually very good for us!

Finally, the high protein content in lamb makes it a no-brainer ingredient for those on the keto diet. Most animal protein is considered ‘complete proteins’ as they contain essential amino acids, unlike vegetables, grains, and nuts.
