Lamb Sirloin Roast

This little roast is a go-to meal when I’m craving lamb. It’s enough for two ordinary appetite people or one hungry person and it cooks in 20 minutes.

I start off with slicing garlic and cutting some rosemary sprigs from out back and then getting out some olive oil, salt, pepper, dried thyme and dried rosemary.

Drizzle olive oil on the lamb and rub it all over both sides. Peel and slice a clove of garlic and then with a sharp paring knife, poke holes in the lamb. Slide a slice of garlic into each hole and follow that with the end a sprig of rosemary. Sprinkle with salt, pepper, thyme and dried rosemary and you’re done all the work.

While the lamb comes to room temperature, preheat the oven to 200C/400F and when the oven is ready, this little pillow of lamb goodness will be ready for the oven. Roast for 20 minutes if you like your lamb medium rare and 25 minutes if you like it more well done. Always test the internal temperature of your lamb with a thermometer.

I think I need to choose a better knife to cut the meat with. Sorry about that. I was really hungry.

With the grilled potatoes, wilted spinach with mashed roasted pumpkin on top – this was a mighty nice meal. When I lived in the states, I rarely ate lamb but here in Australia it’s on the menu often. Do you like lamb?
