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.

Easy Lamb Roast Dinner (video)

25 mins prep + 2 hrs cook
6 servings
Quick and easy, one-pan roasted lamb dinner with potatoes and carrots.

Ingredients 

  • 3 pounds leg of lamb or beef chuck roast
  • oil, for frying
  • Salt and black pepper
  • 1 large onion, sliced
  • 6 large carrots, chopped
  • 2 pounds baby potatoes, or cubed potatoes
  • 1 tsp herb de provence or Italian herb blend
  • 1/2 tsp paprika
  • 1/3 cup red wine or broth
  • 2 tbsp finely chopped parsley, for garnish

Instructions

  • Preheat the oven to 400F/205C. Cut the leg of lamb into 1 1/2-inch chunks; avoid cutting the pieces too small. Preheat a large braising pan over medium-high heat and add about a tablespoon of oil to the pan. Once the pan is hot, add the lamb, season it generously with salt and fry for 7 to 8 minutes, until well browned all over. Do this in batches to prevent the meat from stewing instead of frying. Once the first batch is done, take the meat out of the pan and into a separate bowl. 
  • Once all the meat is browned, return it to the pan and add the sliced onion, chopped carrots and potatoes. Add the wine or broth, herbs, paprika and season generously with ground black pepper. Using a spatula to toss all the ingredients together, making sure that everything is well seasoned and coated. Cover the pan with a tight fitting lid. Watch my video recipe to see how I do it. 
  • Roast the lamb dinner at 400F for 2 hours, covered the entire time. About halfway through, remove it from the oven and stir. When ready to enjoy, garnish with fresh parsley. 
  • 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.
