How to Make Lamb Roast

I love making this recipe because it’s super easy to put together! Always start by preheating the oven to 400F/205C so it’s ready to go. Next, prepare the meat. I like to purchase Costco’s grass-fed boneless leg of lamb from New Zealand for this recipe and others. The bone is already removed, which makes things so much easier!

  • Prepare approximately 3 pounds of lamb, cutting it into 1-1/2 inch pieces – larger chunks work better for this recipe. This roast dinner can also be prepared with beef using tri-tip or chuck roast.

Next, it’s time to brown the meat. I recommend doing this in batches so the meat gets well browned and caramelized and doesn’t stew in the pan. First, preheat a large braising pan over medium-high heat, add a bit of oil and brown the meat for 7 to 8 minutes, seasoning generously with salt. Next, add in the carrots, potatoes, onion, red wine, seasonings and toss everything together. It’s that simple!!! If you don’t want to use wine, beef or veggie broth will also work great!

Methods of Preparation

As much as I love to use a traditional oven and let the lamb roast dinner bake for a few hours, I know not everyone has the time! Here are a few ways of preparing this dish!

  • For traditional oven preparation, preheat the oven to 400F as soon as you get started. Roast the lamb and potatoes for 2 hours, keeping it covered the entire time. Half way through at the hour mark, use a wooden spoon or spatula to toss the ingredients.
  • For slow-cooker, follow the recipe as written and transfer the browned lamb and the rest of the ingredients into a slow cooker. Cover and set the temperature to ‘HIGH’ for 5 to 6 hours. Stir once about 4 hours in.
  • For pressure cooker, follow the recipe as written and combine all the ingredients in your pressure cooker. Set the cooker to a beef/lamb/meat setting and pressure cook for approximately 30 minutes.
