🔪 How To Make Leg of Lamb In An Instant Pot
This recipe is practically effortless as your pressure cooker does all the hard work! You will need your Instant Pot, the metal trivet that came with it, a wooden spoon, and your measuring utensils.
A 5-pound boneless leg of lamb will yield about 10 servings.
- Season. Add 2 tablespoons of olive oil to the Instant Pot and turn on the saute setting, then season your 5-pound leg of lamb with 1 teaspoon of both salt and pepper.
- Sear. Once your Instant Pot is heated, sear the seasoned leg of lamb for 4 minutes on each side. Then, remove the lamb from the pot and set it aside.
- Saute. While still on the saute setting, add the 1 cup of sliced onion to the Instant Pot. Saute for a 2-3 minutes until fragrant. Add 4 garlic cloves and saute for an additional 30 seconds.
- Deglaze the pan. Deglaze the pan by pouring in 4 cups of beef broth and using a wooden spoon to scrape the browned bits off the bottom. Add the 2 teaspoons of dried rosemary and then turn off the saute setting.
- Place lamb in the pot. Place the trivet into the Instant Pot and set the seared leg of lamb on top of it.
- Cook. Close and seal the lid of the pot and set it to manual pressure cook for 45 minutes.
- Release pressure. Once the time is up, allow the Instant Pot to naturally release the pressure (NPR) for 20 minutes before performing a quick release.
- Transfer the lamb. Carefully open the lid of the pot and transfer the lamb to a serving tray or cutting board.
- Rest. Allow the lamb to rest for 10 minutes before slicing and serving with the broth poured over the top or use it to make my lamb gravy.
Serve your leg of lamb with some homemade mint sauce and mashed potatoes! For some more ideas, take a look at what to serve with lamb. Enjoy!
💭 Angela's Tips & Recipe Notes
- The Instant Pot will not start the timer until it has reached pressure, which could take 10-15 minutes.
- A good rule of thumb is to cook your lamb for 9 minutes per pound for medium-rare or 11 minutes per pound for medium.
- If you are using a bone-in leg of lamb, your meat will need to cook longer. Cook for 10 minutes per pound for medium-rare or 13 minutes per pound for medium.
- I don't recommend cooking your lamb past medium in order to enjoy juicy, flavorful, and tender meat!
🥡 Storing & Reheating
There are ton of different recipes you can make with leftover lamb! Keep leftover lamb in an airtight container in the fridge for up to one week.
To freeze, place meat into a freezer-safe container and freeze for up to 6 months, keeping the meat and broth separate. Allow it to thaw out overnight before reheating.
Reheating Leg of Lamb
Place your lamb into a baking dish with some broth and cover it with foil. Bake in the oven at 300°F (150°C) until heated all the way through.

❓ FAQ
This really depends on the cut of meat! Lamb shanks or stew meat, for example, become amazingly tender and delicious when cooked for longer periods of time. However, lamb chops or leg of lamb (as well as most other cuts of lamb) are already incredibly tender cuts of meat and can easily become tough or chewy when overcooked.
Leg of lamb is best enjoyed when it is medium-rare to medium as it can become tough if overcooked. You'll want to cook your boneless leg of lamb in the pressure cooker for 9 minutes per pound for medium-rare or 11 minutes per pound for medium.
I highly recommend searing your lamb for the best flavor. If you skip this step, the meat won't be as juicy or flavorful.
