Instant Pot Irish Lamb Stew

Step 1

Brown the meat. Pat the pieces of lamb with a few paper towels to dry them. Sprinkle with arrowroot powder and a bit of salt and pepper. Turn the Instant Pot to sauté mode and heat the oil. In batches, add the meat to the Instant Pot, and let it cook for about 2 minutes per side. Set it aside on a plate.

Step 2

Cook in the Instant Pot. Add the onions to the Instant Pot, and saute for a few minutes until softened. Add the Guinness (if using) to deglaze the bottom of the pan. Use a wooden spoon to scrape any browned bits off the bottom. Pour in the broth. Add the carrots, potatoes, lamb, and seasonings. Cover and turn to high pressure for 35 minutes. Allow for a natural pressure release.

Step 3

Finish and Serve. Once the pressure has completely released, open the lid. Stir in the green peas and allow them to cook with the stew for a few minutes. Optionally, you thicken the broth by making a slurry. Whisk more arrowroot powder with about 1/4 cup of the broth in a small dish, then stir that into the stew. Set the Instant Pot to Sauté mode and allow the stew to simmer for about 10 minutes, stirring occasionally. Ladle the soup into bowls, sprinkle with fresh thyme, and season with a little salt and pepper.
