Description

Instant Pot Irish Lamb Shanks. A taste of the River Slaney, with potatoes and carrots, thanks to my pressure cooker.


Ingredients

Scale
  • 1 tablespoon vegetable oil
  • 4 lamb shanks
  • 2 teaspoons fine sea salt
  • 1 large onion, minced
  • 1 stalk of celery, minced
  • 1 carrot, peeled and minced
  • 2 cloves garlic, crushed
  • 1 teaspoon fresh thyme (or substitute dried)
  • ½ teaspoon fine sea salt
  • 1 cup Guinness (or another stout, or more broth)
  • 1 cup chicken broth (preferably homemade, or substitute water)
  • ½ teaspoon fine sea salt (if using homemade broth)
  • ¾ pound baby potatoes
  • 1 pound carrots, peeled and cut into 2-inch lengths

Instructions

  1. Sear the lamb shanks: In an Instant Pot or other pressure cooker, heat the vegetable oil using Sauté mode adjusted to high until the oil is shimmering. (Use medium-high heat with a stovetop PC). Sprinkle the lamb shanks with 2 teaspoons of salt. Brown the shanks in two batches: put 2 shanks in the pot, meaty side down, and cook until browned, about 4 minutes. Move the browned shanks to a bowl and brown the second set of shanks.
  2. Sauté the aromatics: Add the onion, celery, carrot, and garlic to the pot. Sprinkle with the thyme and ½ teaspoon salt. Sauté for five minutes, or until the onions soften, occasionally scraping the pot with a flat edged wooden spoon to loosen any browned bits of lamb or onion. Add the beer to the pot, bring to a simmer, and simmer for 1 minute to boil off some of the alcohol. Scrape the bottom of the pot one last time to loosen any browned bits. Stir in the chicken broth, then add the lamb shanks and any lamb juices from the bowl. Add the potatoes and carrots on top of everything.
  3. Pressure cook for 45 minutes with a Natural Release: Lock the lid and pressure cook at high pressure for 45 minutes in an Instant Pot ("manual" or "pressure cook" mode), or for 40 minutes in a stovetop cooker. Let the pressure to come down naturally, about 20 minutes.
  4. Serve: Unlock the lid, tilting it away from you to avoid the hot steam. Gently move the potatoes and carrots to a serving bowl, using tongs or a slotted spoon. Remove the lamb shanks to a platter. Pour the liquid in the pot into a fat separator and let it sit for a few minutes for the fat to separate. Pour a little of the defatted liquid over the shanks and vegetables, then serve, passing the rest of the sauce at the table. Enjoy!

 

Notes

  • This recipe is better in a larger Instant Pot - 8 or 10 quart - not because of the extra volume, but because of the width of the pot. The long bone in the lamb shank fits in the larger pots better. It will work in a 6 quart pot, but try to get the shortest shanks you can find - 8 inches or less - to make sure they’ll fit.
