Semi-Boneless Leg of Lamb - this recipe calls for a semi-boneless leg around 4.5 pounds. This is the size that fits best in my 6-quart Instant Pot - anything large won't fit. As I mention in the Top Tips section below if you can't find the exact 4.5 pound roast buy larger and cut in down to the needed weight. Cut in slices then into bite-size pieces perfect for a stew, casserole, or soup.
Extra Virgin Olive Oil
Garlic - fresh garlic, minced is best!
Kosher Salt
Ground Black Pepper
Dried Herbs - use any favorite combination of dried herbs - I used parsley, thyme, rosemary
Beef or Lamb Stock - use either lamb or beef stock, and broth is fine too.
Carrots - peel and slice the carrots into larger pieces about 1-1/2 inches so they don't go mushy. If this matters to you, make them prettier but cut on a diagonal.
Celery Stalks - cut into larger 1-1/2 inch pieces
Onion - use any favorite onion, I used a yellow onion.

How To Make This Instant Pot Lamb Leg Recipe

Here's how to make this Instant Pot Leg of Lamb:

For complete instructions, please see the printable recipe card below.

Season the Lamb

Rub 4 tablespoons of olive oil over the outside of the roast. Then follow with garlic, herbs, and salt and pepper.

Seasoning the leg of lamb with oil, salt, pepper, and herbs prior to searing.

Sear The Roast

Add 2 tablespoons olive oil to the pressure cooker pot. Using the Sauté setting, preheat the pot to high.

Sear the lamb roast until it is golden brown, approximately 4 to 5 minutes. Flip over and repeat. Remove the roast from the pot and set it aside.

Searing the leg of lamb in the pressure cooker

Add Remaining Ingredients

Place carrots, celery, and onions in the bottom of the pressure cooker.

Adding vegetables to the bottom of the Instant Pot

Place the roast (and any juices that have accumulated) back into the pot, fat side up, on top of the vegetables. Pour stock over the top.

Pressure Cook

Secure the pressure cooker lid and set the pressure cooker to high for 25 minutes. (for a medium-rare roast the general guideline is: 25 minutes for a 4-pound roast, 30 minutes for a 6-pound roast)

Once the pressure cooker cycle is complete, allow the pressure to release naturally for 15 minutes, then follow with a quick release.

Serve

Remove the lamb roast from the pot and cover with foil (leave the vegetables in the pot to keep warm).

Removing the cooked roast from the pressure cooker pot.

Let the lamb roast sit for 10 minutes covered with foil, then slice and serve.

Variations

Here are a few ways you can vary or make substitutions to your pressure cooker lamb:

Use dried or fresh herbs, in any combination that you like. Go Greek and use herbs popular from that region (oregano, rosemary, marjoram, dill, and fennel). Feeling French-inspired? Use an Herbs de Provence blend (thyme, rosemary, savory, marjoram, and oregano)
While the carrots, celery, and onions infuse flavor into the roast, if you are in a hurry you can omit them. You could also add more vegetables if they will fit in your pot, but offset any additional vegetables with 1/2 to 1 cup more stock.

Top Tips

Make-ahead tip: Prep the lamb in advance by rubbing the olive oil, garlic, and seasoning on the roast. Wrap in plastic and keep up to 2 days prior to cooking. The vegetables can all be cut and prepped in advance as well!
Make sure the roast and the vegetables don't go over your max fill line. You can place the vegetables under the roast and up the side if needed.
The ideal roast weight that will fit in your pressure cooker will probably be around 4.5 pounds. If you can't find the exact size of roast in weight, buy a bigger one and trim it down to 4.5 pounds. I literally do this all the time. Cut the extra raw lamb into bit size chunks and freeze it for later use in a lamb stew or another delicious recipe!
Make sure that you season and then sear your lamb before pressure cooking it. This will add flavor to the meat and make it more delicious.
This recipe results in a medium-rare roast that is still pink in the middle. As with all roasts, the outside will more done than the inside. Serve the medium to well-done meat lovers first, and those that like it more rare last.
