Why Choose Lamb on a Ketogenic Diet?
Lamb is a fatty cut of red meat, naturally rich in protein, B vitamins, and essential minerals like zinc and iron. Unlike lean meats that may not provide enough fat for keto, lamb offers the right balance for those on a low-carb, high-fat diet. Plus, it’s naturally low in carbs, making it perfect for clean eating without sacrificing flavor.
Ingredients
- 2 lb. leg of lamb
- 6 garlic cloves (peeled and halved)
- 1 tbsp. rosemary leaves (fresh or dried)
- 1 tsp. ground black pepper
- 1/2 cup reduced-sodium beef broth
Instructions
- Preheat your oven to 400°F (204°C).
- Place the lamb leg in a roasting pan.
- Using a knife, make small incisions throughout the lamb and insert garlic halves into the slits.
- Sprinkle rosemary and black pepper evenly over the meat.
- Pour the reduced-sodium beef broth around the lamb in the pan.
- Roast for 30 minutes at 400°F to create a flavorful crust.
- Reduce oven temperature to 350°F (177°C) and continue roasting for another 1 hour (or until internal temperature reaches 145°F for medium-rare).
- Let the lamb rest for 10 minutes before slicing. Serve warm with keto-friendly sides.

Health Highlights
One serving of lamb contains about 22g of high-quality protein — essential for muscle maintenance and satiety. It’s also a great source of conjugated linoleic acid (CLA), a naturally occurring fat linked to improved body composition and metabolic health. Rosemary and garlic not only elevate flavor but also bring antioxidant and anti-inflammatory properties to the table.
Serving Suggestions
- Serve with mashed cauliflower or roasted Brussels sprouts
- Add a keto gravy using pan drippings and xanthan gum
- Pair with a green salad drizzled in olive oil and lemon
Pro Tips
- Let the meat rest before slicing to lock in juices.
- Use a meat thermometer to avoid overcooking.
- Substitute rosemary with thyme or oregano for variation.
