Sear the lamb. Use paper toweling to pat the pieces of lamb dry. Place meat into a bowl with arrowroot powder and a bit of salt and pepper, and toss to coat.
Turn the Instant Pot to sauté mode and heat the oil. Working in batches, arrange a single layer of meat into the hot oil. Sear for about 2 minutes per side, then set the seared lamb aside on a plate and sear the next batch.
Add the diced onions to the hot oil and sauté for 4-5 minutes, until softened. Pour the beer (or broth) in to deglaze the bottom of the Instant Pot liner. Use a wooden spoon to scrape up any browned bits off the bottom.
Pour in the broth. Add the carrots, potatoes, lamb, and seasonings. Lock the lid on, close the steam release, and manually set the IP to cook at high pressure for 35 minutes. Allow a 15-minute natural pressure release before carefully opening the pressure valve to release any remaining steam.
Finish and Serve. Once the pressure has completely released, unlock and remove the lid. Stir in the green peas and allow them to cook with the stew for a few minutes.
Optionally, you can thicken the stew by making a slurry of 2 tablespoons cold water mixed with 2 tablespoons arrowroot. Stir the slurry 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 additional salt and pepper if desired.
