A festive leg of lamb is a wonderful centerpiece for special celebrations. Traditional methods might take up to 8 hours of slow cooking in the oven and many arduous preparation steps, but our easy Instant Pot recipe will put dinner on the table in no time. Although cooking lamb shoulder seems to be the go-to recipe when using this protein, don't let the size of a leg of lamb be discouraging, as our recipe is easy, delicious, and time-saving.
Seasoned with garlic and fresh herbs, this leg of lamb is cooked to medium-rare juicy perfection. Simple side dishes like white or brown rice, quinoa, mashed potatoes, or cauliflower rice for a low-carb approach, are excellent choices. A green salad with a fresh herby dressing will pair perfectly with the robust flavor of this leg of lamb.
Serve this Instant Pot dish at your next celebratory meal, holiday gathering, or Easter feast.
"The Instant Pot makes cooking a whole leg of lamb incredibly fast. If you like your lamb more done, cook it a few minutes longer. My roast was just shy of 4 pounds and came out medium-rare after 30 minutes. To enhance the herb flavor, serve this with an herby sauce like gremolata."—Danielle Centoni
For the Lamb:
1 (4-pound) boneless leg of lamb
2 large carrots
1 large onion
4 cloves garlic, crushed and minced, or 2 teaspoons garlic powder
2 tablespoons olive oil, divided
1 tablespoon finely chopped fresh rosemary
1 tablespoon finely chopped fresh thyme
1 1/2 teaspoons kosher salt
1/2 teaspoon freshly ground black pepper
1 1/2 cups unsalted chicken stock
For the Gravy:
3 tablespoons cornstarch
3 tablespoons cold water
Steps to Make It
Gather the ingredients.
Bring the lamb to room temperature before cooking, about 1 hour. Pat the lamb dry with paper towels. Truss the lamb with kitchen twine in several places, about 1 1/2 to 2 inches between tie, so it is uniform in thickness.
Peel the carrots and onion. Slice the carrots on the diagonal into 2-inch lengths. Cut the onion into 6 to 8 wedges.
In a small bowl, combine the garlic with 1 tablespoon of the olive oil, the rosemary, thyme, salt, and pepper. Rub the mixture all over the lamb.
Add the remaining 1 tablespoon of olive oil to the Instant Pot and choose the sauté setting. When the oil is hot, add the lamb, turning to sear on all sides, about 7 minutes total.
Cancel the sauté setting. Add the chicken stock and scrape up the brown bits. Add the sliced carrots and onion wedges to the pot.
Lock the lid in place on the Instant Pot and turn the venting knob to the sealing position. Select the manual setting, high pressure, and set the time to 35 minutes (for medium doneness level).
When the time is up, let the pressure release naturally for 15 minutes. Carefully turn the knob to the venting position to release the remaining pressure. Remove the meat and vegetables to a platter and keep warm with a foil tent. The temperature will rise another 5 to 10 degrees as it rests.
Strain the liquids into a bowl or gravy separator, skim and discard the fat, and return the liquids to the Instant Pot. Select the sauté setting.
In a separate bowl, combine the cornstarch with the cold water and mix until smooth.
Stir the cornstarch mixture into the simmering liquids and stir until thickened, 4 to 5 minutes. Taste the sauce and adjust the seasonings as needed.
Place the thickened gravy in a saucer and serve with the leg of lamb and vegetables.
- When browning, if the leg of lamb isn't as brown as you'd like, transfer the roast to a baking pan and place it under a preheated broiler for about 5 minutes. Turn the pan a few times so the lamb will brown evenly.
- Do not use glass bakeware when broiling or when a recipe calls to add liquid to a hot pan, as glass may explode. Even if it states oven-safe or heat resistant, tempered glass products can, and do, break occasionally.
Try cooking these potatoes using the Instant Pot and serve a complete meal:
- When the roast is done, transfer it to a platter along with the vegetables. Cover and keep warm in a 170 F to 200 F oven. Place 1 1/2 pounds of baby potatoes in a steaming basket inside the Instant Pot with the lamb liquids. Select the manual setting, high pressure, for 8 minutes. Do a quick release and remove the potatoes to the platter with the lamb. Make the sauce as directed.
For more complex and deep flavors:
- Replace about 1/2 cup of the chicken stock with dry white or red wine, or if you want to skip the wine, add 1 tablespoon of red wine vinegar to the pot alongside the stock to add some acidity into the cooking juices.
- Use additional spices of your liking, such as turmeric, red chile flakes, dried sage, dried marjoram, ground cumin, or a pinch of nutmeg to enhance the leg of lamb's flavor.
How to Store
- Store the cooked leftovers in an airtight container for up to 3 days.
- If you have plenty of leftovers and you'd like to freeze them, portion and place in zip-top bags. Freeze for up to 3 months. Thaw overnight in the fridge before reheating.
Does Lamb Get More Tender the Longer You Cook It?
Some cuts of lamb, like lamb shanks or stew meat, benefit from a long, slow cooking process, becoming more tender as they cook. However, most cuts of lamb, like lamb chops and leg of lamb, are already tender to begin with and will become tough if over-cooked. Aim for medium or medium-rare.
